Reviewed the docs against this session's landed cli/unity-test-runner changes and found real, worth-fixing gaps rather than assuming everything was already covered.

cli build command

Six new options had zero documentation footprint: --build-profile, --manual-exit, --skip-activation, --run-as-host-user, --enable-gpu, --git-config-extensions (game-ci/cli#62, #67).

game-ci test's Unity support

The doc described it vaguely as "provided by the detected engine plugin." It now has a real, concrete implementation (game-ci/cli#59) — Unity's own native CLI test runner via --unity-cli-args — worth describing directly instead of deferring entirely to a plugin abstraction. Explained why it's a raw pass-through rather than typed flags (Unity's own docs point to unity test --help as the only authoritative reference).

build-unity-image --recipe

A fully implemented, real feature (game-ci/cli#56/#61) — a declarative YAML recipe file, with recipe fields taking priority over CLI flags — had no documentation at all.

unity-test-runner's coverageEnabled

New opt-out input (game-ci/unity-test-runner#311) added specifically to work around real coverage-instrumentation crashes/compile errors on some Unity versions. It was undocumented, meaning the exact users who'd need it had no way to discover it.

Verification

yarn build — compiles clean, no new broken links or routes (the pre-existing "duplicate routes" warning for /docs/docker/versions is unrelated to this change).

Summary by CodeRabbit

  • Documentation
    • Expanded Unity CLI build guidance with build profiles, license handling, editor exit controls, host-user execution, Windows GPU support, Git configuration, and platform restrictions.
    • Documented game-ci test, Unity’s experimental test runner, raw CLI argument support, and custom test runner alternatives.
    • Added guidance for disabling code coverage when it causes test failures; coverage remains enabled by default.
    • Documented YAML recipes and the --recipe option for custom Unity image builds, including recipe settings taking priority over CLI flags.

…overageEnabled

Reviewed the docs against this session's landed changes and found real
gaps - several new, real options had zero documentation footprint:

- cli build command: --build-profile, --manual-exit, --skip-activation,
  --run-as-host-user, --enable-gpu, --git-config-extensions (game-ci/
  cli#62, #67) were entirely undocumented.
- game-ci test's Unity support: the doc described it vaguely as
  "provided by the detected engine plugin" - it now has a real, concrete
  implementation (game-ci/cli#59, Unity's own native CLI test runner via
  --unity-cli-args) worth describing directly instead of deferring to a
  plugin abstraction.
- build-unity-image's --recipe flag (game-ci/cli#56/#61) - a declarative
  YAML recipe file, and the priority-over-flags design decision - had no
  documentation at all despite being a fully implemented, real feature.
- unity-test-runner's coverageEnabled input (game-ci/unity-test-runner
  #311) - an opt-out for code coverage instrumentation added specifically
  to work around real crashes/compile errors on some Unity versions - was
  undocumented, meaning the exact users who'd need it had no way to
  discover it from the docs.

Verified with `yarn build` - compiles clean, no new broken links/routes.

Review Change Stack

Warning

Review limit reached

@frostebite, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 54 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The documentation adds Unity build and test options, configurable test coverage, and YAML recipes for Docker image builds.

Changes

Unity build and test documentation

Layer / File(s) Summary
Build and test CLI options
docs/03-github-cli/02-build.mdx
The build guide documents new build options, platform restrictions, Unity’s official test runner, and raw --unity-cli-args passthrough.

Test coverage configuration

Layer / File(s) Summary
Coverage configuration
docs/03-github/03-test-runner.mdx
The test-runner guide documents the optional coverageEnabled setting, its true default, and behavior when set to false.

Docker image recipes

Layer / File(s) Summary
Docker recipe configuration
docs/08-docker/05-custom-images.mdx
The custom image guide documents the --recipe option, YAML fields, CLI mappings, invocation syntax, and recipe precedence.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🔵 Low · up to 1ee6f

The documentation adds coverage for new CLI, recipe, and Unity test-runner options, but the current text still contains an inaccurate Unity test example and incomplete recipe guidance that could cause copy-paste failures or configuration confusion. It is mergeable with explicit owner follow-up to correct these bounded documentation issues.

In `@docs/03-github-cli/02-build.mdx`:
- Around line 154-171: Update the Unity CLI description to reflect the stated
release timeline: replace the 2025 claim with the accurate release information
and identify 0.1.0-beta.7 as the minimum version supporting unity test, --mode,
and --output if appropriate. In the game-ci test example, replace the unverified
--platform and --report arguments with --mode editmode --output results.xml,
while preserving the raw pass-through explanation.

In `@docs/08-docker/05-custom-images.mdx`:
- Around line 86-95: Update the recipe field mapping documentation to explicitly
state that push is not supported in recipe files and must be supplied as the
--push CLI option on every invocation.
- Around line 79-90: Update the documentation to remove the unsupported recipe
invocation, precedence claims, and recipe field mapping table; use the
implemented build-image command and document only currently supported CLI
behavior.

…y push

Per CodeRabbit review on #582, verified directly against Unity's own
docs (docs.unity.com/en-us/unity-cli):

- Unity CLI's actual first public release was April 2026
  (0.1.0-beta.1), not 2025 as originally written - a stale claim
  carried over from earlier, less precise investigation.
- The illustrative game-ci test example used guessed flags
  (--platform/--report) that directly contradicted the same
  paragraph's own stated rationale for --unity-cli-args being a raw
  pass-through (no guessing flag names). Replaced with --mode/--output,
  which Unity's own release notes document as real flags added in CLI
  0.1.0-beta.7 (still noted as "confirm with --help", since the CLI
  reference page itself still has no formal parameter table for test).
- Clarified that --push is not a recipe field - it's a per-invocation
  CLI flag regardless of whether a recipe is used, since whether to
  push is a decision about *this run*, not a property of the build.

Did not act on CodeRabbit's broader claim that --recipe/build-unity-image
isn't implemented and the command is named "build-image" - verified
directly against cli's current source (src/cli-commands.ts,
src/model/build-image/recipe-file.ts, build-image-command.ts) that the
command is build-unity-image, --recipe works standalone (unityVersion
can come from the recipe alone), and the feature is real/merged/tested,
not a stale proposal.

…rsion field

Per CodeRabbit follow-up on #582, verified against the current cli
source (build-image-command.ts's own --help text literally says
"Required unless provided via --recipe"; recipe-file.ts's RecipeFile
interface has an optional version field with no CLI flag equivalent).
