feat: compile-check closes its miss-side gaps and is shown as an ordinary command

[hatayama]

Summary

uloop compile-check closes the remaining gaps on its miss side and is shown as an ordinary command: it is listed in --help, uloop list --names, shell completion, the README, and the glossary, and uloop skills install installs its skill. The decision and the exact guarantee are recorded in ADR 0018 (docs/adr/0018-compile-check-is-its-own-command-and-is-shown.md).

This is the integration branch feature/compile-check-visible (cut from main at e917059). Every change arrived through a reviewed pull request against the branch:

• docs: record that compile-check stays its own command and is shown #3355 docs: ADR 0018 records that compile-check stays its own command and is shown
• fix: compile-check detects a reference the assembly definition lost #3356 fix: a reference an assembly definition lost is detected and refused with COMPILE_CHECK_UNITY_BUILD_REQUIRED
• feat: compile-check detects build settings that moved since the last Unity build #3357 feat: build settings that moved since the last Unity build are detected (a record written by the first run after a build; added scripting defines are checked one-way when ProjectSettings.asset was saved after that build)
• feat: compile-check keeps the records of skipped dependents and compiles one with no saved generator output #3358 feat: a dependent a run skips keeps its result, baseline and saved generator output; a dependent with analyzers and no saved generator output is compiled once rather than narrowed by name
• fix: compile-check reads identifiers written with unicode escapes #3359 fix: identifiers written with \u / \U escapes are read by the name index
• feat: compile-check picks up new scripts outside every assembly definition #3360 feat: new scripts outside every assembly definition are compiled with the predefined assembly Unity assigns them (Assembly-CSharp and its Editor / firstpass siblings); the folders Unity's importer never compiles are left out
• feat: show compile-check in help, list, completion and skills #3361 feat: compile-check is shown in help, list, completion, README, and skills
• docs: compile-check skill no longer says a skipped dependent is compiled in full next #3362 docs: the skill no longer says a skipped dependent is compiled in full next; a stale comment in the result store follows
• fix: compile-check help points at its skill and logs which define refused a run #3363 fix: compile-check --help closes with the skill guidance line; the one-way define refusal names its part in the VibeLog

What stays undetected

ADR 0018 lists the remaining limitations (a) through (h): a generator reading a referenced assembly, async method builder changes, Unity versions without the Library/Bee build-trace files, settings changed before the record exists, new scripts in package folders without an assembly definition, analyzer configs added since the last build, Dedicated Server targets, and Unity 6 build profiles that override Player Settings. Each is also stated in docs/compile-check.md and the skill.

Verification

• Every pull request passed its CI and an independent review; the Go modules pass gofmt, go vet, golangci-lint, and go test.
• A final acceptance round on a large Unity 6 project (6000.3.15f1, hundreds of assemblies) ran eleven scenarios against a binary built from this branch: zero false errors and zero refusals that a subsequent uloop compile did not clear. The refusals for a lost assembly-definition reference, an added scripting define, and a removed scripting define all cleared as designed; new scripts outside assembly definitions compiled with Assembly-CSharp; a script under Assets/StreamingAssets/ was left out; a dependent of 1,293 sources kept its changed-files check after the run that skipped it.

Compatibility

• No change to the IPC wire format: protocolVersion and REQUIRED_CLI_PROTOCOL_VERSION are untouched.
• No C# change under Packages/src; the package change is the skill's frontmatter (internal: true removed) and its text.
• cli/common changed, so the shared-inputs stamps of both native CLI components are updated by scripts/stamp-release-inputs.sh in the pull requests that changed it.
• Release version fields and changelogs are untouched; release-please stamps them.

Merge Risk: 🔵 Low · up to be310

The compile-check skill guidance may overstate when a scripting-define change is refused. An agent could trust a stale response-file check on the first run after a Unity build. The risk is small and the fix is a documentation edit, so the change is mergeable with that follow-up.

Security architecture risk: 🔵 Low · up to be310

The changes retain the existing local execution boundary and add validation safeguards. No introduced security issue was established, but documented validation limitations and incomplete review coverage warrant a cautious assessment.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The workflow concerns a selected Unity project, but compiler and analyzer execution carries local process authority. Project-relative working directories, timeouts, and locks should not be interpreted as containment for malicious project inputs. This execution capability predates the PR.

Trust Boundaries and Controls

• observed — The inspected execution path retains compiler and worker timeouts, temporary request cleanup, and a project-wide advisory lock. The new metadata is serialized through the existing response path; no new recipient or authentication transition was established.

Resilience and Maintainability Implications

• inferred — Locking, post-compilation input revalidation, and atomic record replacement limit stale-success recovery within cooperating compile-check runs. They do not authenticate build inputs against a hostile filesystem writer; the settings stamp uses path, modification time, and size.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Qualify the scripting-define refusal.

If a scripting define is removed before the first compile-check run after a Unity build, this skill says the run is refused. The Limitations section says that change is not detected. An agent can therefore treat a stale response-file check as validation of the new defines. State the first-run exception here, then regenerate the .agents/ and .claude/ copies.
