What it measures: How tangled the control flow is — methods with many branches are hard to test and change.

Method: Cyclomatic complexity per method (1 + decision points), computed exhaustively across production source; test projects separated by convention. Deterministic.

216 method(s) exceeded the cyclomatic complexity threshold of 15; the worst was script_apply_edits.script_apply_edits at 146. A further 14 method(s) were over the threshold but excluded as flat dispatchers (a long switch/match over independent cases: many branches, almost no nesting), the largest being ScreenshotUtility.GetGlyph at 41 — they are counted neither in the figure above nor in this dimension's score. 9 files carry no cyclomatic complexity row at all for this reason — every one of their over-threshold methods was excluded, so the exclusion is disclosed nowhere in the file itself: MCPForUnity/Runtime/Helpers/ScreenshotUtility.cs (ScreenshotUtility.GetGlyph at 41), MCPForUnity/Editor/Tools/Physics/ManagePhysics.cs (ManagePhysics.HandleCommand at 25), MCPForUnity/Editor/Services/AssetGen/ImageResultFormat.cs (ImageResultFormat.FromBytes at 24), TestProjects/AssetStoreUploads/Packages/com.unity.asset-store-tools/Editor/Validator/Scripts/Services/Validation/AssetUtilityService.cs (AssetUtilityService.GetAssetPathsFromAssets at 22), MCPForUnity/Editor/Tools/GameObjects/GameObjectMoveRelative.cs (GameObjectMoveRelative.GetDirectionVector at 20), and 4 more not listed here. They are named here because the per-file figures other dimensions report are taken BEFORE this exclusion, so such a file can show a high maximum complexity elsewhere in this report and nothing here, with nothing to reconcile the two.

What to do

1. Bring the 2 bodies over 120 down to 120 or less in Cyclomatic Complexity — start with script_apply_edits.script_apply_edits (cyclomatic 146), script_apply_edits._iter_csharp_tokens (cyclomatic 121). — This score is capped by its worst body, so a finding fixed alone moves it by almost nothing — the next one down takes its place. Refactoring these 2 together lifts Cyclomatic Complexity from 4.4 to about 4.7/10, projected with the scoring formula itself and assuming each lands exactly at 120; a cleaner split scores higher.
2. Enforce Cyclomatic Complexity in CI to reach Verified (currently Documented). — Hardens enforcement from Documented toward Prevented — provenance only; does not change the score.

7 outdated, 0 deprecated direct UPM dependency(ies) of 8 graded, 1 pinning defect(s), across 4 UPM manifest(s) and 1 committed packages-lock.json. Currency is graded on the version each project RESOLVED in its lockfile, not the minimum its manifest declares, and against the newest release that project's own Unity editor can take — a later release requiring a newer editor is not counted as an upgrade this repository is behind on, because installing it is not something the owner can do without changing editor. Whether any of these packages is UNMAINTAINED is not graded: the registry publishes no maintenance status, and release age does not stand in for one. Whether any is UNUSED is not graded either — that is a source question, not a registry one. Known CVEs in this dependency graph are D30's question.

What it measures: Whether the licenses of third-party packages are compatible with your policy.

Method: Third-party package licenses resolved from declared package metadata and checked against the configured policy (allow/deny/copyleft). Deterministic; clean = no incompatible license found at metadata depth.

Maturity: Documented → Verified → Prevented · effective 10.0 / 10 · rule-coverage 100% · ceiling Verified

0 of 43 shipped Python distribution(s) use a banned license. Licences were resolved from PyPI over the distributions a consumer installs — this repository's 8 declared runtime requirement(s) closed transitively over each distribution's published `requires_dist` (35 reached that way). Requirements it states ONLY under an extra, a PEP 735 dependency group, a Poetry dev group or a dev-named requirements file are excluded: pip does not install any of them for a consumer. ★ This repository commits no dependency lockfile that this pass reads, so each licence is the one PyPI publishes for the distribution's CURRENT release rather than for a pinned version. This repository publishes itself under MIT, which is its own choice and is not judged here. ★ COVERAGE OF THIS VERDICT: it grades this repository's Python distribution dependencies and nothing else. The repository also declares package.json and a Unity UPM manifest (Packages/manifest.json or a package's package.json), and the licences of those dependency graphs were NOT read by this pass — a gap in this engine's coverage, not a statement about them. So this result says the graded closure carries no banned licence; it does NOT say this repository's licensing is clear.

Maturity: Documented → Verified → Prevented · effective Exemplary / 10 · rule-coverage 100% · ceiling Documented

The documentation is comprehensive and well-structured for a large architecture/roadmap project: the root README covers releases, an external-analytics doc explains cookieless analytics with public vs private visibility, and dedicated docs cover instance routing, physics management, Python three-layer design, remote auth, and a detailed 2026 roadmap. The release-notes document is clipped mid-series but its outline (Release Notes; v10.x series; What's Changed) exists, so the absence of an overview section in the root README does not trigger any defect. The repository's documentation is comprehensive and well-structured. The READMEs for each project (MCP for Unity) describe what they are and how to use their contents, while architecture/design docs cover the full scope (privacy-first telemetry, transport modes, API compatibility shims, release workflows). A single clipped architecture doc section does not invalidate its completeness; all outlined sections appear in the visible text. The READMEs are focused on usage rather than installation/contribution for their directories. (9 of 25 sampled documents could not be assessed: 1 of 3 evaluation groups failed.)

What it measures: Whether files that change together actually belong together — pairs that repeatedly co-change in git history despite having no explicit code dependency, surfacing the hidden/logical coupling (and boundaries in the wrong place) a static scan can't see.

Method: Pairwise co-occurrence over the per-commit file sets in git history (production source only — tests and generated dropped): Degree-of-Coupling = shared ÷ min individual revisions, reported above noise floors (each file ≥10 revisions, ≥5 shared commits, ≥50% strength); sweeping commits excluded. Deterministic over fixed history.

Coverage: Population: PRODUCTION source files only — test and generated files are dropped before pairing, so a class co-changing with its own test (trivially ~100%) can't drown the real production↔production coupling. Pairs ranked by Degree-of-Coupling. A non-source file is never a coupling PARTICIPANT either: documentation, schemas, config and data files are dropped with the rest, so a code↔docs pair — a command and the reference page that restates it — is not reported however strongly the two co-change; nor is coupling that runs THROUGH a build step or config file.

What it measures: Whether the build pipeline provides supply-chain integrity — generated provenance/attestation, signed artifacts (cosign/sigstore), an SBOM, and pinned build actions. Presence of the configuration, not a runtime guarantee.

Method: Supply-chain provenance/signing read deterministically from CI/build config (.github/workflows, .gitlab-ci.yml, azure-pipelines, Jenkinsfile, .circleci) + the release surface: four signals — generated provenance/attestation (SLSA/in-toto/actions-attest), artifact signing (cosign/sigstore/gitsign), an SBOM (syft/sbom-action/*.spdx.json/*.cdx.json), and SHA-pinned build actions — scored 10·present/denom.

What it measures: Whether the repository publishes a coordinated-vulnerability-disclosure policy (SECURITY.md or security.txt) with a reporting contact, so finders know how to report a vulnerability. Presence of a policy file with a contact, not whether the policy is adequate or honoured.

Method: Vulnerability-disclosure policy read deterministically from the repo: a SECURITY.md (root/.github/docs) or .well-known/security.txt / security.txt, regex-checked for a reporting contact (email / URL / mailto). Present + contact → 10; present without a contact → 4; NotApplicable when no policy file exists (it may live off-repo). Detects the policy file's presence + contact, not its adequacy.

What it measures: Whether any dependency the repository declares is published as MALICIOUS rather than merely vulnerable — a package that is an attacker's work, in any ecosystem osv-scanner reads. Scored apart from D30 because the answer is binary: there is no safe version to upgrade to, and the fix is to remove the package and rotate every credential it could have read.

Method: The same dependency scan D30 reads, partitioned on the scanner's own classification rather than rescanned: a row is MALICIOUS when its id is in the `MAL-` space (the ossf/malicious-packages feed) OR its `database_specific.cwe_ids` carries `CWE-506` ("Embedded Malicious Code"). Both channels are structural; the summary text is deliberately NOT read, because a malicious-package record whose summary says only "Critical severity vulnerability" is a real shape ([GHSA redacted]) and a text matcher misses it. Scored BINARY: any surviving row is 0, whatever its severity and however many CVEs sit beside it — a hostile dependency is not a quantity. Applicability and degradation are D30's: NotApplicable only when no ecosystem is readable, and an unscannable ecosystem degrades rather than reading clean. SCORED, not informational.

What it measures: Whether anyone still ships security patches for the platform this repository RUNS ON — the runtime it pins and the framework majors its own constraints hold it to. Separate from D12 because the question differs: a current Django on an end-of-life Python is perfectly up to date and completely unsupported, and the fix is a migration rather than a version bump. What the repository says it merely SUPPORTS is never charged.

Method: End-of-life PLATFORM read from the repository's own declarations and graded against a FROZEN, dated table of vendor support dates — no network, no feed, no API, so this dimension answers identically inside a closed scan fence. Two subjects: a RUNTIME the project pins (a single or all-end-of-life TargetFramework, a .nvmrc or .python-version, a requires-python CAP) and a FRAMEWORK major a dependency constraint cannot move off (a caret, tilde or exact version; `vue@^2.7.16` pins Vue 2). A FLOOR is deliberately never charged — `requires-python = ">=3.8"` states what a package SUPPORTS, not what it runs on — and a multi-target project is charged only when EVERY target is out of support. Runtime 4.0/product capped 8.0, framework 1.5 capped 4.5. The table is safe to freeze because a statement about support that ended in the past cannot become false: it loses recall as it ages, never precision, and a test asserts every entry predates the freeze date. Disjoint from D31 (a container image's OS layer) and D29 (the toolchain a CI workflow installs). Abstains when the repository declares no platform this pass reads — never scores it clean.

Maturity: Documented → Verified → Prevented · effective 10.0 / 10 · rule-coverage 100% · ceiling Documented

0 end-of-life runtime(s) and 0 end-of-life framework(s), read from 0 platform declaration(s) and 8 dependency declaration(s). This dimension reads what the repository says about ITSELF — a pinned target framework, a version file, a capped requires-python, a Rust toolchain pin, a framework major a constraint cannot move off. A FLOOR is deliberately never charged: `requires-python = ">=3.8"` states what the package SUPPORTS, not what it runs on, and a well-maintained library declares exactly that while running its own CI on a current release. The end-of-life facts are FROZEN and dated, so this dimension needs no network and answers identically inside a closed scan fence; as the table ages it loses recall and never precision, because a statement about support that ended in the past cannot become false. The OS layer of a container image is D31's question and the toolchain a CI workflow installs is D29's; this row is neither.

Other · Architecture — How the codebase splits by code ROLE — domain, application, infrastructure, test, generated. The significance map behind the knowledge/coupling weighting, and a DDD signal in its own right: a thin domain core under fat infrastructure is the anemic-domain smell, quantified. How each file's role is decided, because the split is only as good as that: a generated name or a build-output tree makes it Generated, a test project makes it Test, and otherwise the file's NAMESPACE and PATH words are matched against fixed vocabularies in a fixed ORDER — domain, then infrastructure, then application — so a file whose words hit two layers is counted under the earlier one. A production file matching none of them counts as application, so that share reads 'application or unclassified' rather than a measured application layer. Roles come from naming convention, never from what the code does. On this repository the split was taken from the source tree on disk rather than from a loaded .NET workspace, so a file's role is decided by its PATH segments alone — no declared namespace was available to add to the evidence — and generated output is excluded from the census entirely rather than counted as a generated share.

Method: Roslyn line-count by code ROLE: every source file classified Domain/Application/Infrastructure/Test/Generated by namespace + path convention (the shared CodeRoleClassifier), then significant lines summed per role. Deterministic; the advisory score is the business-logic (domain+application) share of production code.

Coverage: Population: ALL source files, each bucketed into ONE of five roles (Domain/Application/Infrastructure/Test/Generated) by namespace + path convention — a file whose layer isn't named in the convention falls to Application (the neutral default), and the split is line-count, not semantic depth or business value.

What to do

• The domain core is a small share of production code, but most of the rest matched no layer vocabulary at all — so this is not yet an anemic-domain finding. The namespace/path convention could not place that code, which makes the composition above a statement about the naming, not about the design. Name the layers (or check that the repository's conventions differ from the ones this check knows) before reading a thin domain into it.

Other · Architecture — Whether the project-reference graph is acyclic (cycles block independent build/deploy and signal eroding boundaries).

Method: Project reference cycles via elementary-DFS over real .csproj references, using the engine shared with D5/D7; cyclic versus acyclic. Exhaustive, deterministic.

Other · Architecture — Whether dependencies point inward (Domain ← Application ← Infrastructure/Web) — the clean-architecture dependency rule, checked across the project graph.

Method: Layer violations by name-segment inference (Domain/Core to Application to Infrastructure/Web) over the project-reference graph. Exhaustive over all projects, deterministic.

Other · Architecture — Whether interfaces stay focused rather than fat — the Interface-Segregation principle (SOLID 'I').

Method: Roslyn scan: public interface declared-member counts (accessors fold into their property/event); fat-interface threshold (over 15 declared members) flagged per type. Each finding also reports the distinct-OPERATION count — members counted by name, so an overload group counts once — which decides whether it states the caller-side ISP harm or the implementer-side burden of an overload set. TypeScript: exported interfaces that declare behaviour, counted over their REQUIRED operations (method signatures and function-typed properties with no `?`, once per signature) — data-shape interfaces and ambient .d.ts declarations are outside the population; JavaScript declares no interfaces and is not applicable. Deterministic, type-level.

• `IMcpClientConfigurator` declares 16 members: `Id`, `DisplayName`, `Status`, `ConfiguredTransport`, `SupportsAutoConfigure`, `IsInstalled`, `SupportedTransports`, `GetConfigureActionLabel`, `GetConfigPath`, `CheckStatus`, `Configure`, `Unregister`, `GetManualSnippet`, `GetInstallationSteps`, `SupportsSkills`, `GetSkillInstallPath`. Counted as the author wrote them — a property is ONE member and its get/set accessors are not counted separately, and an event counts once. A wide interface forces every implementer and caller to depend on methods they don't use (the Interface-Segregation 'I' in SOLID). Split it into focused role-interfaces. — MCPForUnity/Editor/Clients/IMcpClientConfigurator.cs:9

What to do

• Split fat interfaces into focused role-interfaces so clients depend only on what they use.

Other · Architecture — Whether production projects stay free of references to test projects — tests may depend on production, never the reverse.

Method: Csproj graph: each production project checked for references to test projects (identified by test-framework presence, not name). Zero violations is clean. Deterministic.

Other · Security — Whether sensitive data is encrypted at rest and in transit and keys are vaulted.

Method: Roslyn plus filesystem scan: encryption presence (EF ColumnEncryption, key-vault references, HTTPS enforcement) and key-derivation KDF detection. Deterministic.

What to do

• Strengthen data-at-rest protection: vault your keys (Azure Key Vault / AWS KMS / IDataProtector key ring) and encrypt the most sensitive columns (EF HasConversion encryption or provider-native column encryption) — partial coverage still leaves gaps.
• Enforce HTTPS (UseHttpsRedirection / RequireHttpsMetadata) so data in transit is always encrypted.

Other · Security — Whether access is authorized by default — a framework authorization attribute/decorator or policy, or imperative guard methods (throw-on-violation) called from handlers.

Method: Roslyn scan: [Authorize] usage and authorization policies, plus imperative throw-on-violation guard methods detected via syntax. Deterministic.

• Authorization IS enforced here (by imperative guard methods that throw on violation) — this is NOT a claim that the code is unprotected. What's missing is a NAMED rule set: the guards encode the access rules inline, so the rules can't be listed, reviewed or tested apart from the call sites that apply them. Recommendation, not a defect.

What to do

• Name the access rules — give each one a named predicate/policy object your guards consult, so the rule set can be reviewed and unit-tested independently of the call sites that enforce it.

Other · Security — Whether data has a defined lifetime — retention periods, TTLs, cleanup jobs (storage limitation).

Method: Roslyn scan: retention/TTL configuration presence in schema; CascadeDelete detected but not scored as retention control. Deterministic, gated by PII presence.

• A retention mechanism is present, but the data-lifecycle is not yet complete — missing: a scheduled purge / cleanup job (PurgeOlderThan / CleanupJob), a documented retention period / data-expiry.

What to do

• Complete the data-lifecycle story: an expiry limit (a declared maximum age for the stored data — a retention-age setting, or a store-level TTL where your storage offers one), a scheduled purge/cleanup job that enforces it, and a documented retention period covering the personal data.

Other · Code Health — Unreviewed-generation residue: shipped members still throwing NotImplementedException, and placeholder string literals left in non-test, non-generated code. Scored as a quality signature, never as a claim about authorship.

Method: Roslyn syntax scan: NotImplementedException throws and placeholder string literals in non-test, non-generated shipped code. Deterministic, code-shape signature.

Other · Code Health — Unfinished work detected by code SHAPE, not keywords: members that only throw a "not implemented" exception, methods that take inputs and return a constant, async methods that never await, dead `if (false)` / `#if false` branches, and skeleton types most of whose members are holes. A real, objective slice of technical debt.

Method: Roslyn syntax scan: incompleteness by code shape (constant-returning methods, async-never-await, #if false branches, guards that return what the code already falls through to, tests an earlier guard already decided, comparisons against NaN, skeleton types), not keyword-gated. Deterministic, code-shape heuristic.

• The `if` and its `else` contain the same 1 statement, so no input can make the condition matter. Implement the distinction that was intended, or drop the branch and keep the body.

• Control only reaches here when `string.IsNullOrEmpty(name)` is false, because the guard on line 18 exits otherwise. This test is therefore always true and its `else`, and any code it is meant to skip, is unreachable. Implement the distinction that was intended, or delete the test. — MCPForUnity/Editor/Tools/GameObjects/GameObjectCreate.cs:101
• Control only reaches here when `diagnostics.HasErrors` is false, because the guard on line 67 exits otherwise. This test is therefore always false and everything it guards is unreachable. Implement the distinction that was intended, or delete the test. — MCPForUnity/Editor/Tools/Sprite2D/SpriteFullSetup.cs:77
• A line of code has been commented out rather than removed — dead weight that rots and confuses. Delete it (version control remembers). (×35) — MCPForUnity/Editor/Helpers/GameObjectSerializer.cs:235, MCPForUnity/Editor/Helpers/GameObjectSerializer.cs:245, MCPForUnity/Editor/Helpers/GameObjectSerializer.cs:480, …

What to do

• Clear the softer debt: remove commented-out code and dead branches, re-enable or delete skipped tests, and replace blanket warning suppressions with targeted ones.

Maturity · Maturity — Whether the repo and its projects have a README, and whether it's substantive and current.

Method: Filesystem scan: README presence, word count, and headings for depth; git history for staleness. Exhaustive across root and project dirs, deterministic.

What to do

• Add a build/run (quick start) section to the root README — the first thing a newcomer needs.
• Explain in the README how to run the tests. Add a section called Testing to the README in the repository's top folder, saying how to run the test suite.
• Add an 'Architecture' / 'How it works' section to the root README — the high-level shape.
• Add a README to the 1 of 4 project(s) that lack one — worth up to 0.5 pts.

Maturity · Maturity — Whether key decisions (ADRs) and the high-level shape (C4/diagrams) are written down.

Method: Filesystem scan: ADR folder/naming conventions or content, plus Mermaid/PlantUML/C4/architecture.md discovery. Exhaustive, deterministic.

• No Architecture Decision Records found — no conventional ADR directory, no numbered `NNNN-title` documents in any markup this check reads, and nothing ADR-shaped by content. Design rationale recorded elsewhere (a design-notes tree, a mailing list, pull-request discussion) is not visible to this check and is not re-findable per decision, so a future maintainer cannot ask why one choice was made and get an answer.

What to do

• Record your significant design decisions. Write one short document per decision, giving its date, the situation, the decision and its consequences, and keep them together with your other design documents. A docs/adr folder with each file named by number and title is the easiest place to find them.

Maturity · Maturity — Whether the repo is organised deliberately — src/test separation and consistent project naming.

Method: Filesystem scan: src/test folder separation and namespace-prefix consistency (majority RootNamespace agreement). Exhaustive across projects, deterministic.

• Production code isn't grouped under a src/ folder — it's spread across several top-level directories, so there's no one place that says 'this is the product'.

What to do

• Group production code under src/ (or split deliberately, e.g. backend/ + frontend/) so production and tooling code aren't mixed at the root.

Maturity · Maturity — Whether the README actually describes the code that exists (LLM-judged, advisory).

Method: Judged by language model at low temperature: README accuracy versus actual projects, within a disclosed tolerance. Advisory, not a measured number.

Readiness · Readiness — Whether an automated pipeline builds and tests every change.

Method: Filesystem scan: CI workflow files (.github/workflows, .gitlab-ci.yml, etc.) for build and test stages. Exhaustive, deterministic.

Readiness · Readiness — For a library: a deliberate (small) public API surface and explicit semantic versioning so consumers can depend on it safely.

Method: Roslyn scan: public API surface area and semantic-versioning markers (SemVer attributes, changelog entries) for libraries; off .NET, a library is the ecosystem's publication act (an npm package that is not private and names an entry point, a PyPI distribution with a build system, a Rust library crate, a Maven/Gradle module that publishes, a Go module with no package main, a gemspec, a Composer library, a SwiftPM library product, a pub.dev or Hex package), its surface is the share of types the language model records as public (Rust, Swift, Java, Kotlin, Go, Dart; not measured where the model records no type visibility or, as in TypeScript, only module-level export), and its version is read from the manifest, a semver CHANGELOG, release tooling or semver git tags. Exhaustive, deterministic.

Readiness · Readiness — Whether SAST, secret/dependency scanning and performance benchmarking are wired in (presence, not runtime).

Method: Filesystem scan: SAST configuration, dependency-update automation, secret scanning, and a benchmark harness or benchmark step — in this repository's own ecosystem. Exhaustive, deterministic.

• No static application security testing detected. For this repository's stack, add `semgrep --config=auto` plus gitleaks for committed secrets — this tree has no MSBuild project file, so CodeQL's csharp pack (which traces a build) and NuGet security analyzers (which are referenced from a project) have nothing to attach to as a CI step. What was searched, so you can tell an absence from a miss: the 136004 CI workflow file(s) in this repository, and the scanner and linter configuration checked in beside them. A scan that runs outside CI, one configured in your forge's web UI rather than in a committed file, or a tool whose name is none of those this check carries, is not seen — if that is your case the row is wrong, and saying so is more useful than adding a second scanner.

What to do

• Add a SAST step to CI running what this repository's stack ships: `semgrep --config=auto` plus gitleaks for committed secrets — this tree has no MSBuild project file, so CodeQL's csharp pack (which traces a build) and NuGet security analyzers (which are referenced from a project) have nothing to attach to — so a security regression fails the build instead of landing.
• Enable Dependabot/Renovate or a dependency-review gate.
• Add gitleaks/trufflehog in CI to block PRs that introduce committed secrets.

Readiness · Readiness — Whether releases are automated and safely reversible (probes, rolling updates, approval gates) — from manifests/pipeline files, not the live environment.

Method: Filesystem scan: deployment manifests/IaC (K8s YAML, Helm, Terraform) for rolling updates, probes, approval gates, migration hooks. Exhaustive, deterministic.

• Deployment is orchestrated by compose, but no service declares a `healthcheck:` and nothing pins a previous image to fall back to — the runtime can tell that the container is up, not that it is serving, so a bad release is harder to detect and reverse.

What to do

• Add a `healthcheck:` to the served compose service — probing the endpoint it already answers on where it has one — with `depends_on: condition: service_healthy` on whatever waits for it, and keep the deployed image tag immutable and recorded so rolling back is re-pointing at the previous tag rather than rebuilding.

Readiness · Readiness — Whether disaster recovery is planned and codified — backups, geo-recovery, RTO/RPO, persistence guarantees — from IaC + container manifests + docs, never the live cloud.

Method: Filesystem scan: disaster recovery, backup, geo-recovery, RTO/RPO, persistence guarantees from IaC, manifests, and docs. Exhaustive, deterministic, never a live environment.

What to do

• Document RTO/RPO and a tested restore procedure (a backup config alone isn't disaster recovery).
• No persistence guard on critical data stores — use Docker named volumes (or your orchestrator's persistent-volume equivalent) so the data store can't be wiped by a container recreate (or, in cloud, set purge-protection / soft-delete / prevent_destroy).

Readiness · Readiness — Whether releases are traceable — a maintained changelog and explicit version stamping.

Method: Filesystem scan: changelog file presence and version tags in csproj or git tags. Exhaustive, deterministic.

Readiness · Performance — Whether the code protects its performance with benchmarks — a benchmark suite, allocation/memory measurement, and (ideally) a CI gate. Presence is credited as a bonus, never a deduction.

Method: Repo + source scan: BenchmarkDotNet referenced (csproj/source), [Benchmark]/[MemoryDiagnoser] attribute counts, and a benchmark step in CI; off .NET, the same ladder over Go testing.B, Rust criterion/#[bench]/divan, JMH/kotlinx-benchmark, pytest-benchmark/asv/pyperf, tinybench/mitata/vitest bench/benchmark.js and Swift package-benchmark — scored as a bonus ladder (absence is neutral, never a deduction). Deterministic, presence detection.

• No benchmark suite was found by the two searches this check runs. FIRST, a BenchmarkDotNet package reference in any project file — every project the workspace loaded, plus a walk of project files on disk that never loaded, because a benchmark suite is exactly the project a partial load drops. SECOND, a script harness: a file whose name contains `benchmark` and ends `.py`, `.sh`, `.ps1`, `.bash`, `.rb`, `.js` or `.mjs`, credited ONLY when this repository's CI text also mentions benchmarks — a harness no pipeline runs is read as a fixture, deliberately. Neither search can see a benchmark suite in another ecosystem's idiom (a Go `testing.B` file, a JMH or criterion project, a pytest-benchmark run), so this is 'no benchmark found by those two searches', not a verdict that the repository has none. Where code is performance-sensitive, a benchmark guards against silent regressions — but it's a bonus here, not a deduction.

What to do

• Add a benchmarking harness for the hot paths and run it in CI to catch regressions (for .NET, a BenchmarkDotNet project with [MemoryDiagnoser] to track allocations).

Readiness · Performance — Whether the code is written to minimise allocations so it doesn't pressure its host's memory manager — buffer/slice views over copies, object pooling, stack or value-type allocation, and buffer writers. Reward-only: credited where present, never penalised where a simpler style is fine.

Method: Production-source scan: density (per 1k LoC) of allocation-aware APIs — in .NET Span/Memory, ArrayPool/ObjectPool, stackalloc, ValueTask, value-type structs, IBufferWriter, string.Create, SkipLocalsInit; off .NET, with comments and strings blanked, Go's sync.Pool, preallocated slices/maps, Grow, strconv.Append* and buf[:0] reuse; the JVM's NIO buffer views, MemorySegment, primitive collections, pools and literal presizes (plus Kotlin primitive arrays and value classes, Scala AnyVal and @specialized); Swift's reserveCapacity, ContiguousArray, withUnsafe* access and ~Copyable. Activated off .NET on the same floor (400 lines, and benchmarks or 8 uses); Rust and garbage-collected scripting languages are not applicable. Reward-only. Deterministic, syntax/text detection.

What to do

• Raise allocation-aware density on the hot paths — currently 9 use(s) across 99,794 production line(s) (~0.1/1k). More Span/Memory, pooling (ArrayPool/ObjectPool), stackalloc and ValueTask on the allocation-heavy paths climbs this toward 10.

Readiness · Performance — Whether asynchronous code stays responsive — it avoids sync-over-async blocking (a .NET .Wait()/.GetAwaiter().GetResult(), a time.sleep or blocking HTTP call inside a Python coroutine, a *Sync call inside an async JavaScript function, block_on inside a Rust async fn, runBlocking inside a Kotlin suspend function, block() inside a Reactor publisher) that stalls a thread or event loop and risks deadlock, and, where the code is a reusable library on .NET, awaits with ConfigureAwait(false) so it never captures and stalls its caller's context.

Method: Production-source scan: sync-over-async blocking counted everywhere — .Wait()/.GetAwaiter().GetResult() in .NET; off .NET, read from the language model, a blocking call inside an async function (Python, TS/JS, Rust, Kotlin, Swift, Dart) or inside a Java method returning a Reactor Mono/Flux or a Scala method returning a Future or effect — and, for a .NET library with ≥5 awaits, the share of awaits using ConfigureAwait(false). Deterministic, syntax/text detection.

• 9 blocking call(s) on async work (.Wait()/.GetAwaiter().GetResult()) — these waste a thread and can deadlock wherever a synchronization context is in play (a UI thread, or a caller that has one).
• `.GetAwaiter().GetResult()` blocks this thread until the async work completes — it wastes a thread-pool thread for as long as the work runs and can deadlock wherever a synchronization context is in play (a UI thread, or a caller that has one). (×8) — MCPForUnity/Editor/Services/BridgeControlService.cs:141, MCPForUnity/Editor/Services/Transport/TransportManager.cs:192, MCPForUnity/Editor/Services/Transport/Transports/WebSocketTransportClient.cs:236, …
• `Item1.Wait()` blocks this thread until the async work completes — it wastes a thread-pool thread for as long as the work runs and can deadlock wherever a synchronization context is in play (a UI thread, or a caller that has one). — TestProjects/AssetStoreUploads/Packages/com.unity.asset-store-tools/Editor/Validator/Scripts/Services/Validation/ScriptUtilityService.cs:168

What to do

• Make the call chain async end-to-end and await it — never block on a Task with .Wait()/.GetAwaiter().GetResult().

Other · Security — Cryptographic hygiene (weak hash/cipher, password key-derivation). This codebase has no web surface, so transport/header/cookie/CSRF controls are N/A and only crypto is scored.

Method: Roslyn plus filesystem scan: HSTS/security headers, secure cookies, input validation, middleware order, weak crypto (MD5/SHA1/DES); HTTPS-metadata context-aware. On a repository with no .NET source it reads JavaScript/TypeScript, Dart, Ruby, Scala, Rust or Elixir source itself (test, vendored, generated and minified paths not) for the arms that hold whether or not the code serves HTTP: a weak hash or cipher, key material fixed in the source, a TLS client that accepts any certificate, and (JavaScript/TypeScript, Ruby, Scala, Rust and Elixir) an obsolete TLS version; the server controls are not assessed there, and a Dart, Ruby, Scala, Rust or Elixir repository that serves no HTTP of its own is N/A on them. Deterministic.

• MD5/SHA1 is constructed here, and both are collision-broken. If this digest protects anything — a signature, an integrity or tamper check, a credential, or any value an attacker can influence — that is a real weakness: use SHA-256+ for content integrity, or a KDF (PBKDF2/Argon2/BCrypt) for password storage. If it only derives a non-security identifier (a cache key, a file or mutex name), collision resistance carries no security consequence here; make that intent explicit instead — a non-cryptographic hash such as `System.IO.Hashing.XxHash64`/`Crc32` says it in code — since the algorithm alone cannot distinguish the two uses. (×5) — MCPForUnity/Editor/Helpers/PortManager.cs:331, MCPForUnity/Editor/Helpers/ProjectIdentityUtility.cs:92, MCPForUnity/Editor/Services/Transport/Transports/StdioBridgeHost.cs:1190, …
• `Iterations` fixes PBKDF2-SHA-256 at 200,000 iterations. A key-derivation function's only defence is the cost of ONE guess, and that cost is this number — the algorithm choice does not set it. Current OWASP guidance is 1,300,000 PBKDF2 iterations with HMAC-SHA1, 600,000 with SHA-256 and 210,000 with SHA-512; scrypt at N=2^17, r=8, p=1 (or an equivalent N·r·p product); Argon2id at 19 MiB of memory and 2 iterations (or an equivalent row); bcrypt at a work factor of at least 10. This figure divides the attacker's work by a factor of tens or hundreds against the same stolen hash, on hardware they already own. Where what is derived is short or low-entropy — a PIN, a numeric parental code, a four-character token — the whole keyspace falls in the time this parameter buys, and no salt or constant-time comparison changes that. Raise the count to the current published figure for the PRF you use, measure it on the slowest hardware that must run it (a target of roughly 100 ms per derivation is the usual budget), and read the value from configuration so a deployment can raise it again without a rebuild. Where the derived value must interoperate with a format someone else fixed, the count cannot move — derive a SEPARATE value for anything you own rather than inheriting the external format's price. — MCPForUnity/Editor/Security/SecureKeyStore/EncryptedFileKeyStore.cs:20

What to do

• Review each MD5/SHA1 use by what it protects: replace it with SHA-256+ (or a KDF for passwords) where the digest is security-relevant, and switch it to a non-cryptographic hash (`System.IO.Hashing.XxHash64`/`Crc32`) where it only derives an identifier such as a cache key or a mutex name. This repository constructs a collision-broken hash (MD5/SHA1) at 5 sites, not one: `MCPForUnity/Editor/Helpers/PortManager.cs:331` (SHA1), `MCPForUnity/Editor/Helpers/ProjectIdentityUtility.cs:92` (SHA1), `MCPForUnity/Editor/Services/Transport/Transports/StdioBridgeHost.cs:1190` (SHA1), `MCPForUnity/Editor/Setup/SkillSyncService.cs:499` (SHA1), `MCPForUnity/Editor/Tools/Blender/BlenderBridgeTool.cs:885` (MD5). Each is a separate decision — fixing only the line this row cites leaves the others in place.
• Raise the cost parameter to current guidance — PBKDF2 at 1,300,000 (HMAC-SHA1), 600,000 (SHA-256) or 210,000 (SHA-512) iterations; scrypt at N=2^17, r=8, p=1; bcrypt at a work factor of 10 or more — or move to a memory-hard KDF (Argon2id, scrypt) where the platform offers one. Read the parameter from configuration and tune it to roughly 100 ms per derivation on the slowest hardware that must run it, so the price can be raised again without shipping new code.

Other · Code Health — Whether the code avoids sync-over-async (deadlock-prone blocking on tasks) and async void.

Method: Roslyn syntax scan: async methods scanned for .Wait()/.GetAwaiter().GetResult() and async-void outside event handlers. Deterministic, hard fact per invocation.

• `async void` can't be awaited and its exceptions crash the process instead of propagating. Return `Task` — or, where the delegate contract requires void (timer/event/callback registrations), make this a thin void shim that awaits a Task-returning inner method inside try/catch so exceptions are contained. (×16) — MCPForUnity/Editor/MenuItems/BlenderBridgeMenu.cs:22, MCPForUnity/Editor/MenuItems/BlenderBridgeMenu.cs:29, MCPForUnity/Editor/MenuItems/BlenderBridgeMenu.cs:36, …
• Blocking on a Task with `.Wait()`/`.GetAwaiter().GetResult()` can deadlock (and wastes a thread). Prefer awaiting it: make the caller `async` and `await` instead. Where a synchronous entry point must stay — a public sync API you cannot break, or a process entry point that must not return until the work finishes — the block belongs in ONE documented bridge and never inside code that is already async; and where it already is that bridge, give the wait a TIMEOUT so a hung task fails the call instead of hanging the process. (×8) — MCPForUnity/Editor/Services/BridgeControlService.cs:141, MCPForUnity/Editor/Services/Transport/TransportManager.cs:192, MCPForUnity/Editor/Setup/SkillSyncService.cs:293, …
• `Task.WaitAll` blocks this thread until the tasks complete — sync-over-async: it can deadlock under a synchronization context and it parks a thread for as long as the work runs. `await Task.WhenAll(…)` instead. — MCPForUnity/Editor/Services/McpEditorShutdownCleanup.cs:47
• Reading `.Result` of a task that has not completed blocks this thread until it does — the same block as `.Wait()`: under a synchronization context (Blazor, a UI thread, classic ASP.NET) it deadlocks, and on the thread pool it parks a thread for as long as the work runs. `await` the task instead (make the caller `async`); where a synchronous entry point must stay, keep the block in ONE documented bridge with a timeout. (×10) — MCPForUnity/Editor/Services/TestJobManager.cs:735, TestProjects/AssetStoreUploads/Packages/com.unity.asset-store-tools/Editor/Api/Abstractions/AuthenticationBase.cs:37, TestProjects/AssetStoreUploads/Packages/com.unity.asset-store-tools/Editor/Api/Abstractions/PackageUploaderBase.cs:26, …
• `.Wait(…)` blocks this thread until the task completes or the bound expires — sync-over-async: it can deadlock under a synchronization context and it parks a thread while it waits. `await` the task (with `.WaitAsync(timeout, token)` where the bound matters). — MCPForUnity/Editor/Services/Transport/Transports/StdioBridgeHost.cs:493
• Blocking on a Task with `.Wait()`/`.GetAwaiter().GetResult()` wastes a thread and, if the task needs a context this one is holding, deadlocks. `Dispose()` returns void by contract, so it cannot simply `await`: signal the work to stop first (cancel its token, set its stop flag) so the wait is short, give the wait a TIMEOUT so a hung task cannot hang shutdown, and — where callers can use it — add an awaitable teardown (`DisposeAsync`/`StopAsync`) beside the synchronous one and let `Dispose()` remain the bounded fallback. — MCPForUnity/Editor/Services/Transport/Transports/WebSocketTransportClient.cs:236

What to do

• async void method: ImportSelection

Other · Code Health — Whether any branch is dead by construction — a switch arm whose label can never equal a case-normalised subject, or an `else if` whose predicate the arm above has already swallowed.

Method: Roslyn syntax + semantics: switch labels compared against the subject's own case normaliser, and if/else-if chains checked for a literal an earlier arm's containment test already swallows. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a child process that has BOTH standard streams redirected drains both — reading one to the end while the other is never read deadlocks once the child fills the unread pipe.

Method: Roslyn syntax + semantics: ProcessStartInfo launches with both streams redirected, checked for a drain of each stream across the enclosing type. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same rule: a `spawn` imported from `child_process` whose stdout and stderr are both pipes (no options, no `stdio`, or `stdio` of `'pipe'`), bound to a local that never leaves its scope, where exactly one of the two streams is read, the other never, and the child’s `close`/`exit` (or the read stream’s end) is awaited; a shell redirect in the call’s arguments or a `kill` of the child suppresses it. The same rule reads Python’s `subprocess.Popen`, Dart’s `Process.start`, Ruby’s `Open3.popen3`, and Scala’s JDK process starts (`new ProcessBuilder(…).start()` with no `redirectErrorStream`/`redirectError`/`redirectOutput`/`inheritIO`, `Runtime.getRuntime.exec`) where one of `getInputStream`/`getErrorStream` is read and the other never while `waitFor()` is called or the read stream is read to its end. Deterministic, provable per finding. Advisory.

• `RedirectStandardError` is set here, but nothing in this type ever reads `StandardError` — while `StandardOutput` is read to the end. The child blocks as soon as it fills the StandardError pipe (~4 KB, never more than 64 KB), and it can then never finish writing StandardOutput, so the read-to-end above never returns and the `WaitForExit` timeout beside it does not help: the timeout bounds the WAIT, not the read that precedes it. Drain both — read one stream on a background thread (`BeginErrorReadLine()` with an `ErrorDataReceived` handler, or a `Task` running the second `ReadToEndAsync()`) and await both before `WaitForExit()` — or stop redirecting the stream you do not consume. — MCPForUnity/Editor/Security/SecureKeyStore/LinuxSecretToolKeyStore.cs:91

What to do

• Each finding names the span that makes the branch dead and the span it is dead because of. Confirm from the two, then delete the dead arm or fix the predicate that was meant to be reachable.

Other · Security — Whether a hand-rolled public/private IP check can be walked past — a method that unwraps IPv4-mapped IPv6 but returns the opposite verdict for the same host written as IPv4-compatible, 6to4 or NAT64.

Method: Roslyn syntax + semantics: methods that unwrap IPv4-mapped IPv6 and hand-roll IPv4 range carve-outs, checked for whether the IPv6 branch also accounts for the IPv4-compatible, 6to4 and NAT64 embeddings. Deterministic, provable per finding. Advisory.

Other · Security — Whether a length read out of the stream being parsed is bounded before it is allocated or read — an unchecked count taken from the input lets the input choose the allocation.

Method: Roslyn syntax + semantics: integer lengths read from a BinaryReader and spent on a bulk read or an array allocation, checked for any comparison or bounding call on the value anywhere in the method. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a loop that shortens a string until it fits a length budget has a floor — one with none grinds the value down to the empty string, or past it into a negative-length `Substring`.

Method: Roslyn syntax + semantics: while/do loops whose body's only effect on a string is to drop its last character, checked for whether anything — a direct comparison on the length, a body guard, a break — bounds that length below. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same rule: a `while`/`do` loop whose body’s one assignment to a value is `x = x.slice(0, -1)` or `x = x.slice|substring|substr(0, x.length - 1)`, driven by a condition that reads `x.length` only as a term of a larger expression — never compared directly, never tested for truthiness, and with no other read of `x` — and whose body has no `break`, `return`, `throw` or `if` naming `x`. Deterministic, provable per finding. Advisory.

Other · Security — Whether a walk that recurses through a JSON/XML tree handed in by its caller bounds how deep it will go — an uncapped walk lets the document's nesting choose the stack depth, and the resulting StackOverflowException cannot be caught.

Method: Roslyn syntax + semantics: methods that take a JSON/XML document node and call themselves with a child of it, reachable from an externally-callable member of the same type that accepts a document, checked for any depth parameter, descent counter or threaded arithmetic anywhere in the walk. On a repository with no .NET source it reads TypeScript off the engine’s own token stream (test, vendored, generated and minified paths and `.d.ts` not) with the same rule: a function or method with a parameter typed as a document value — `unknown`, `any`, `object`, `Record<string, unknown|any>`, a JSON alias (`JsonValue`, `JSONObject`, …) or a DOM node global the file does not rebind — that calls itself (bare, or through `this` for a method, or hands itself to a call over the value as in `value.map(walk)`) with something it took out of that value and never through an ancestor accessor such as `closest()` or `parentElement`, that is exported or reached from an exported function (a public method of the same exported class) taking such a value, and that names no depth, level, nesting, recursion, remaining or budget anywhere and threads no `+`/`-` arithmetic through a self-call. Plain JavaScript is not read: with no annotation nothing tells a parsed document from a tree the code built itself. Deterministic, provable per finding. Advisory.

• `TrySetShaderProperty` is public and takes the `JToken` from its caller, and it calls itself at line 221 with a child of the node it was given — and nowhere in `TrySetShaderProperty` is there a depth parameter, a descent counter, or any other cap. The walk therefore spends one stack frame per LEVEL of the tree it is handed, so the nesting of the caller's document — not this code — decides how deep the stack goes. A document nested past the stack that remains raises `StackOverflowException`, which .NET neither lets you catch nor unwinds: the process is torn down where it stands, taking every other request in flight with it, and no `try`/`catch` around `TrySetShaderProperty` can intervene. Thread a depth argument through `TrySetShaderProperty` and reject the document past a fixed maximum, or rewrite the descent with an explicit stack. — MCPForUnity/Editor/Helpers/MaterialOps.cs:221

What to do

• Each finding names the externally-callable member that accepts the document and the self-call that descends, and states that no depth parameter or counter exists anywhere in the walk. Confirm from the two, then thread a depth argument through the walk and reject documents past a fixed maximum, or rewrite it with an explicit stack.

Other · Code Health — Whether a type's disposal matches what it OWNS — releasing what it created, leaving alone what it was handed, and not declaring a finalizer for state that has nothing unmanaged to finalize.

Method: Roslyn syntax + semantics: every assignment to a disposable field is read to decide whether the type CREATED the value or was handed it, and the type's disposal is checked against that answer — an injected interface it disposes, a value it constructed and never releases, a finalizer on a type holding nothing unmanaged, and a disposable local whose every reference is a plain member read. A value handed to a container that disposes its contents (a parent control's `Controls` collection, a component `IContainer`) is released by that container and is not reported; generated code is out of population. On a repository with no .NET source the same ownership questions are read in JavaScript/TypeScript off the engine’s own token stream (test, vendored, generated and minified paths not): a class declaring `dispose()`, `[Symbol.dispose]()` or `[Symbol.asyncDispose]()` that disposes a field it was handed through a constructor parameter typed as a repository interface or resolved by a dependency-injection container; that assigns a field only ever from `new X(…)` of a disposable class and neither releases it anywhere in the class nor names it in its disposal member or a method that member calls, nor hands it to anything else; and a `const`/`let` local built from literals only whose every reference opens a statement operating on a non-release member of it. A class is disposable when every repository declaration of its name declares or inherits a disposal member, or when it is a documented library disposable (`vscode` EventEmitter, CancellationTokenSource and Disposable; three.js geometries, materials, textures, render targets, renderers, controls and composers). The finalizer arm has no JavaScript counterpart: a class cannot declare one. Dart is read for the owned-and-never-released arm: a Flutter `State` (or a class declaring `dispose()`/`close()`) whose library-private field is written only with direct creations of a framework controller, `FocusNode`, `StreamController` or periodic `Timer` (or a `.listen(…)` into a field declared `StreamSubscription`), which nothing in the class or its library releases (`dispose`/`close`/`cancel`) and which is never handed on except as a named argument. Ruby is read for the owned-and-never-released arm and the abandoned-local arm: a class declaring an instance `close`, `dispose`, `shutdown`, `stop`, `disconnect` or `terminate` whose instance variable is written only with a blockless core descriptor creation (`File.open`/`new`, `Tempfile`, `Dir.open`, `IO.popen`, the `socket` and `openssl` socket classes) that no method of the class closes and that is never handed on (passed, returned, stored, exposed by `attr_reader`, delegated) — a class whose superclass or mixin lies outside the repository is not judged — and a blockless creation read through and dropped (`File.open(path).read`) or held in a local that is never closed, returned, passed or stored (a `&:read` block-pass, an `autoclose: false` borrow and a `fileno` hand-over are not abandonment). PHP is read for the same two arms: a class (not a trait, and not one using a trait) declaring an instance `close`, `dispose`, `shutdown`, `stop`, `disconnect` or `terminate` whose `private` property (or a `final` class's `protected` one) is written only with a direct core `fopen`, `tmpfile`, `popen`, `proc_open`, `fsockopen`, `stream_socket_client`/`server` or `opendir` that nothing in the class closes (`fclose`, `pclose`, `closedir`, `unset`, a reset to `null`) and that is never handed on, and a handle held in a function's local, or read through as the argument of a reader, that is never closed, returned, passed, captured or stored; a `php://` stream, `curl_init`, `SplFileObject`, `PDO` and a function the repository declares under the core name are not read. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a method that temporarily changes state belonging to the whole process — the working directory, an environment variable — puts it back on EVERY path: a restore reached only when nothing throws leaks the change to the rest of the process.

Method: Roslyn syntax + semantics: method bodies that write the process working directory or an environment variable and write it back in the same body, checked for whether that restore sits in a `finally`/`catch` or only on the straight-line path. On a repository with no .NET source the same rule reads production JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not): `process.chdir`, `process.env.NAME =`/`["NAME"] =` and `delete process.env.NAME`, and Deno’s `Deno.chdir`/`Deno.env.set`/`Deno.env.delete`, paired per function body (a nested function or arrow is its own body, and module top-level code is none), where the last write puts back a local the body captured from the same global or deletes a variable the first write set, with at least one statement between them; a write in a `catch`/`finally` of that body silences it. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether async methods accept a CancellationToken so work can be cancelled (adoption curve).

Method: Roslyn scan: every async method (excluding framework-fixed overrides/Blazor handlers) checked for CancellationToken parameter presence. Deterministic, adoption percentage. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same question: every named async function that itself makes a request an AbortSignal can cancel (global `fetch`, axios and its file-local instances, ky, ofetch) counts, and it is compliant when its parameters or body name a signal or it hands one of its own parameters to the request as options; signatures a framework fixes (JSX event handlers, route and lifecycle exports, request-first handlers, `override`, `'use server'` modules, TanStack `mutationFn`) are exempt unless they take a signal. Deterministic, adoption percentage.

• Only 51/90 async methods accept a CancellationToken, so in-flight work can't be stopped early when the caller gives up — whatever ends it in your host (shutdown signal, timeout, abandoned request, user cancel). Thread a token through the call chain and honour it at each await and loop; where a method genuinely cannot be interrupted, omitting it is a deliberate choice — judge against your hosting model.
• No CancellationToken parameter — this work can't be stopped early once started. (×37) — MCPForUnity/Editor/Services/HttpAutoStartHandler.cs:287, MCPForUnity/Editor/Services/HttpBridgeReloadHandler.cs:146, MCPForUnity/Editor/Services/StdioBridgeReloadHandler.cs:133, …
• Neither takes a CancellationToken nor reads the one of the function it sits in, while it calls something that takes one — this work can't be stopped early once started. Take the token, or pass on the enclosing one. (×2) — MCPForUnity/Editor/Services/Transport/Transports/StdioBridgeHost.cs:1004, MCPForUnity/Editor/Tools/CommandRegistry.cs:433

What to do

• Thread a CancellationToken through async methods so work stops promptly on cancellation.

Other · Code Health — Whether an argument guard throws the exception its own condition describes — a guard that rejects a value for being EMPTY and reports it as `ArgumentNullException` tells the caller a parameter was null when it provably was not.

Method: Roslyn syntax: `throw new ArgumentNullException(nameof(p))` statements controlled by an `if`, whose condition is read for a test that is true of a NON-null `p` — an emptiness test that dereferences it (`p.Count == 0`, `!p.Any()`) or a BCL predicate documented true of the empty value (`string.IsNullOrEmpty(p)`). Deterministic, provable per finding. Advisory.

• The guard on line 698 rejects `projectDir` and line 700 reports that rejection as `ArgumentNullException` — but the condition's own test `string.IsNullOrEmpty(projectDir)` is true of a value that is NOT null: it is satisfied by an EMPTY `projectDir`, and on that path `projectDir` was already proven non-null by the very expression that decided it (`||` short-circuits, so the null test to its left had to be false to get here). So a caller who passes a valid empty argument is told a parameter was null. That is not a wording problem: the exception type is the contract. A caller catching `ArgumentNullException` to handle a real null swallows the empty case with it, and whoever reads the stack trace later is told a failure the source disproves. .NET separates the two on purpose — `ArgumentNullException.ThrowIfNull` and `ArgumentException.ThrowIfNullOrEmpty` are two helpers because they are two failures.

What to do

Confirm from the two, then throw the exception that describes what was actually wrong: `ArgumentException` for a value that arrived empty, or the .NET 8 helpers that spell the whole guard in one line and pick the type for you — `ArgumentException.ThrowIfNullOrEmpty(s)` / `ThrowIfNullOrWhiteSpace(s)` for strings, `ArgumentNullException.ThrowIfNull(x)` followed by `ArgumentOutOfRangeException.ThrowIfZero(x.Count)` for a collection. Splitting the two conditions is usually clearer than picking one exception for both: they are different failures and the caller may want to handle them differently.

Other · Code Health — Whether a `when` guard is free of side effects — a guard that increments a counter or assigns while deciding whether its arm matches applies that change during PATTERN MATCHING, on an arm that may not be selected, and skips it entirely when a short-circuit to its left answers first.

Method: Roslyn syntax: `when` guards on case labels and switch-expression arms, read for a mutation (`++`/`--`/assignment) sitting in a position the guard's own `&&`/`||`/`??`/`?:`/`?.` can skip. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a method that TAKES a lock or semaphore and gives it back from a flag-guarded `finally` returns the value that flag implies — reporting success while the guard hands the primitive back admits a second caller the exclusion was there to keep out, and reporting failure while the guard keeps it leaves nothing to ever give it back.

Method: Roslyn syntax: `try` statements whose `finally` releases a synchronisation primitive under a bare local-bool guard, where the method also TOOK that same primitive before the `try`, checked for a `return` of a bool literal whose value disagrees with the flag state the method's own straight-line assignments put it in. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether the work a diagnostic log line costs is paid only when that line is wanted — C# evaluates a call's arguments BEFORE the call, so a trace/debug message joined or projected out of a collection is built in full on every pass, and then discarded by a sink the shipped configuration leaves switched off.

Method: Roslyn syntax: log calls at a diagnostic level (a `Log`-prefixed method naming Trace/Debug/Verbose, or a bare `Debug`/`Trace`/`Verbose` on a receiver named for a logger), whose argument list is read for a call whose cost scales with a sequence — a LINQ operator, a materialisation, `string.Join`, a serializer — with no enclosing level check or conditional-compilation region. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same rule: a `debug`/`trace`/`verbose` call on a receiver named for a logger, or a `log`-prefixed method naming the level, whose argument calls an array operator (`map`/`filter`/`reduce`/`sort`/…), `Array.from`, `Object.keys/values/entries`, `JSON.stringify`/`util.inspect` over anything but a literal, or an array `join` — outside any arrow or function passed as an argument, which the logger calls only when the level is on — with no enclosing `if`, `&&` or `?:` whose condition names a level, a level string, or the `NODE_ENV`/`__DEV__`/`DEV` build switch. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a value the caller is invited to supply is the value the type actually uses — a constructor parameter stored in a private field that nothing ever reads while the default it was given is spelled out a second time at the site that should have read it, a keyed lookup that falls back to a different setting than the one its key names while the same type falls back to the matching one for that same key, or a culture-sensitive parse given no format provider by a type that feeds its own settable culture to the same kind of parse elsewhere, or a number an entry point writes to standard output under the host's culture while the same entry point formats with the invariant culture elsewhere. Either way, every caller who supplies a value silently gets something else.

Method: Roslyn syntax: private instance fields of a non-partial type assigned in a constructor from one of its own parameters with a `??` fallback, checked for whether anything in the type body reads the field and whether that same fallback expression is spelled out again outside the constructor; and `??` fallbacks onto a member access from a lookup call carrying exactly one string literal, grouped by that key across the type and checked for a fallback member whose folded name disagrees with the key while a sibling site for the same key agrees with it. On a repository with no .NET source the first two arms read JavaScript/TypeScript off the engine’s own token stream (tests included, bundles and vendored paths not): a `#x`, `private` or `private` parameter-property instance field filled in the constructor from a parameter (or one member of one) through `??`/`||` or a parameter default, never read anywhere in the file by name, whose constructed default is spelled again in the class body; and `lookup("key") ?? s.member` grouped by key per class, or per module outside every class. The culture arm has no JavaScript counterpart: its parses take no locale. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a value handed from a callback to the body that waits on it crosses on something built to be crossed — a `Queue<T>`/`List<T>`/`Dictionary<K,V>` written inside an event handler and read back outside it is mutated by two flows at once, and the semaphore or completion source beside it orders how MANY items exist while leaving the collection's own head, tail and backing array unprotected.

Method: Roslyn syntax: method, accessor, local-function and lambda bodies that declare BOTH a non-thread-safe generic collection (`Queue`/`Stack`/`List`/`Dictionary`/`HashSet`/`Sorted*`/`LinkedList`) and a synchronisation primitive (`SemaphoreSlim`/`TaskCompletionSource`/`ManualResetEvent(Slim)`/`AutoResetEvent`/`CountdownEvent`) as locals, then read for a `+=`-registered lambda that raises that primitive while the body outside every lambda waits on it — and, in that scope, a mutating call on the collection inside the lambda paired with a mention of it outside. Any `lock` in the scope abstains it. On a repository with no .NET source the same handoff is read in Java off the engine’s own token stream (test source sets, vendored and demonstration paths not): an `ArrayList`/`LinkedList`/`ArrayDeque`/`PriorityQueue`/`Hash*`/`LinkedHash*`/`Tree*` local and a `CountDownLatch`/`Semaphore`/`CompletableFuture` local, a lambda or anonymous class that raises the primitive and mutates the collection, and a wait outside it; any `synchronized` or `lock()` abstains the body. Because each of those primitives orders what the callback wrote before raising it, only a touch that provably overlaps the callback is convicted: one after the registration and before the next wait, or one in a loop registered-before, waiting on every pass and not declaring the collection. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a condition that tests a value for emptiness indexes that same value only where the test holds — an `||` written one parenthesis too far to the left leaves an index access outside the guard beside it, so the empty case the guard exists to anticipate reaches the index and throws.

Method: Roslyn syntax only, no semantic model: the OUTERMOST `&&`/`||` of every boolean condition, read for a symbol the condition tests for emptiness (`string.IsNullOrEmpty`/`IsNullOrWhiteSpace`, a `Length`/`Count` comparison against a literal, `Any()`, a `Length`/`Count` pattern, or a comparison against `""`) and ALSO indexes. Each `symbol[...]` access is placed by a boolean-reachability walk from the access up to the outermost connective: an access is COVERED when some enclosing step has it in the right operand and the left operand, under the truth value that step forces, proves the symbol non-empty — a recursion over `&&`/`||` whose true- and false-directions are asymmetric. A finding needs BOTH an uncovered access and a covered one on the same symbol in the same condition, which is the agreeing twin that separates a misplaced parenthesis from an unrelated length test. Bare index accesses with no emptiness test in the condition are neither counted nor reported; a non-identifier receiver and a lambda nested inside the condition are outside the population. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a decision taken once per element is taken ABOUT that element — a test inside a counted loop that reads a fixed subscript of the very collection its guarded statement indexes by the loop variable applies element zero's answer to all of them, so the elements that differ from it are all handled wrongly, and in the same direction.

Method: Roslyn syntax only, no semantic model: every `for` statement declaring exactly ONE loop variable, and every `if` inside its body that is not under a nested loop or a lambda. A site enters the population when the `if`’s condition never mentions the loop variable while the statement it guards indexes some collection by that variable ALONE (`c[i]`; `c[i + 1]` and `c[i, j]` are outside it). A finding additionally needs the AGREEING TWIN at the same-collection grain: the condition must read THAT SAME collection at a subscript that does not move — written into the condition, or reached through a local declared BEFORE the loop, so an alias bound inside the body is not followed. Both collection expressions must be simple identifiers. On a repository with no .NET source the same rule reads JavaScript/TypeScript off the engine’s own token stream (tests included, bundles and vendored paths not): a `for (let|var|const x = …; …; …)` with one declarator and a braced body, an alias followed only when it is declared before the loop in a block that encloses it and never assigned inside the loop. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether exceptions are handled rather than silently swallowed or rethrown with lost stack traces.

Method: Roslyn syntax scan: every catch clause counted; empty catches and bare rethrows flagged. Population is all catch clauses, not estimated. Deterministic, hard fact.

• `catch (Exception)` does nothing with the exception it caught — the body neither logs it, rethrows it, nor even names it, so the failure is discarded as completely as by an empty catch. Log it through whatever this codebase already uses to report problems, or let it propagate; if one specific failure genuinely cannot matter, catch exactly that exception type and say why in a comment on the catch. — MCPForUnity/Editor/Helpers/GameObjectSerializer.cs:317

Other · Code Health — Whether a guard written as a NEGATED `||` says what its author meant — `!(a || b || x != k)` is `!a && !b && x == k` by De Morgan, so a bail-out that mixes capabilities the code needs with a fault it refuses turns inside out: it fires only where the capabilities are ABSENT, and lets every value the fault term names walk straight into the body that cannot handle it.

Method: Roslyn syntax only, no semantic model: every logical-not whose operand is a parenthesised `||` chain of two or more disjuncts, flattened (a left-nested `a || b || c` read once would see `(a || b)` as one disjunct). A site enters the population on that shape alone. A finding additionally needs the disjuncts to DISAGREE in polarity: at least one bare boolean read — an identifier or member access, never an invocation, which is a predicate rather than a capability flag — and at least one `x != <constant>`, the only form that negates into an exact-value pin (`== null` negates into a looser requirement and is outside the fault set). Consistently-polarised disjunctions, all-fault or all-capability, are counted and never reported; a negated `&&` is outside the population entirely. No same-receiver gate: it was measured to cost a real defect and remove no false positive. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether a plugin lookup names the type it means — searching every assembly loaded into the process for a candidate whose SIMPLE name equals a string supplied at runtime, and taking the first one found, is decided by assembly LOAD ORDER rather than by this source, so the same name can resolve to a different type on the next run.

Method: Roslyn syntax only, no semantic model: every invocation of `First`/`FirstOrDefault`/`Single`/`SingleOrDefault` whose OWN expression subtree contains both a `GetAssemblies()` call and a `GetTypes()`/`GetExportedTypes()` call — a single-element pick out of every type loaded into the process. A nested selector in the same chain sees no `GetAssemblies()` in its own subtree and is outside the population, so one lookup counts once however many links its chain has. A finding additionally needs both remaining halves: the selector must be `First`/`FirstOrDefault` (`Single`/`SingleOrDefault` reports the ambiguity rather than resolving it, and is counted and never reported), and the chain must carry an `==` comparison of `<lambda parameter>.Name` against something that is not a literal. The receiver must be a plain identifier bound by one of the chain’s own lambdas, which places `assembly.GetName().Name == "X"` outside the rule by construction. One exemption: a `.Name` test joined by `&&` to a `FullName`/`AssemblyQualifiedName` test on the same identifier is spared; joined by `||` it is not. Deterministic, provable per finding. Advisory.

Other · Code Health — Whether log calls use message templates (queryable) rather than interpolated strings.

Method: Roslyn syntax scan: every log call-site counted; interpolated-string first-argument violations flagged. Population is all log calls, not estimated. On a repository with no .NET source it reads JavaScript/TypeScript off the engine’s own token stream (test, vendored and minified paths not) with the same rule: a `trace`/`debug`/`info`/`warn`/`error`/`fatal`/`verbose`/`silly`/`http`/`log` call on a receiver named for a logger, in a package whose own or an enclosing `package.json` declares a logger that carries values as fields (pino, pino-http, nestjs-pino, Fastify, winston, bunyan, tslog, LogTape, roarr), whose first deciding argument is a template literal with substitutions; an object-literal fields argument is stepped over, a plain string message clears the call. Python is read the same way: a `debug`/`info`/`warning`/`error`/`exception`/`critical`/`log` call on a logger in a file that imports the standard library’s `logging` or structlog (loguru, which formats at the call, is not judged), whose message is a whole f-string with a non-constant field; a `%`-formatted, `.format()`-ed or concatenated message is not convicted, as in C#. PHP is read the same way: a PSR-3 level call (`emergency`…`debug`, `log`) on a logger (`$logger`, `$this->logger`, Laravel’s `Log::`, `logger()`, `\Drupal::logger()`) in a package whose `composer.json` requires a PSR-3 logger or a framework that hands one out (psr/log, Monolog, Laravel, Symfony, Drupal, CakePHP), or a file that imports one, whose message is a double-quoted string interpolating a variable; a single-quoted message clears the call, and `sprintf` or `.` concatenation is not convicted, as in C#. Dart is read the same way: a `trace`/`debug`/`info`/`warn`/`error`/`fatal` call on Sentry’s structured logger (`Sentry.logger`) whose message is a whole string literal interpolating a value (`$name`, `${…}`); the `Sentry.logger.fmt` template API clears the call. Dart that logs only through loggers with one message and no fields (package:logging, package:logger, talker, dart:developer) is not applicable rather than a reach gap. Ruby is read the same way: a `trace`/`debug`/`info`/`warn`/`error`/`fatal` call on the console gem’s `Console` (declared by a Gemfile, gemspec or Gemfile.lock, or required) or, where SemanticLogger, Ougai or dry-logger is declared or required, on a receiver named for a logger (`logger`, `@logger`, `Rails.logger`, `log`), whose first deciding argument is, as the whole argument, a double-quoted string interpolating a non-constant value (`#{…}`, `#@ivar`); a plain literal clears the call, keyword arguments are the fields, and a block, `%`-format or `+` concatenation is not convicted. Ruby that logs only through the standard Logger (Rails.logger) is not applicable rather than a reach gap. Deterministic.

• Logging an interpolated string (`$"..."`) collapses the event to plain text — you lose the named, queryable properties structured logging exists for. Use a message template with placeholders: `LogInformation("User {UserId} did {Action}", id, action)`. If these calls go through a logging wrapper that only accepts a pre-formatted string, give the wrapper a template+args overload that forwards to the underlying logger, then migrate call sites to it.

• This method contradicts itself about `mcpServers`: line 98 assigns it with `as TomlTable`, which hands back null rather than throwing when the value is not a `TomlTable`, but line 101 then dereferences it directly with no null test between them and no guard around it.

• 0/599 C# file(s) are in a nullable-enabled context. This repository commits no project file, so nothing sets <Nullable>enable</Nullable> for it: a file is enabled only by its own `#nullable enable`, by a Unity `csc.rsp` with `-nullable:enable` for its assembly, or as a file-based app (`#:` directives) whose `#:property Nullable` does not turn it off. NRTs catch a whole class of null-deref bugs at compile time.

What to do

• Where a method uses `?.` on a symbol and then dereferences it directly, settle the question once: test it before the first use and handle null, or drop the `?.`.
• Put every file in a nullable-enabled context — `#nullable enable` at its top, or commit a project file with <Nullable>enable</Nullable> — and resolve warnings rather than suppressing with `!`.
