chore(ci): add opt-in local checks by BumpyClock · Pull Request #1 · BumpyClock/agent-limits

BumpyClock · 2026-11-01T22:31:29Z

Why

Contributors need optional offline checks before pushing without replacing existing hooks.

Scope

Add an explicit hook installer, clean-checkout and pushed-ref checks, and local validation guidance. Release note: optional pre-push checks are available to contributors.

Verification

Boat hook fixtures passed with stub project commands (13 cases, one policy-specific skip).
Real workspace acceptance remains blocked by the deleted pinned GPUI origin and missing vendor submodule. Native GPUI acceptance is unverified.

Findings

Remove inherited Git repository variables from the fixture environment.
Inspect submodule changes when checking checkout state.
Remove or supply the PowerShell installer.

Summary by CodeRabbit

New Features
- Added an opt-in installer for local pre-push checks. Installation is not automatic and avoids replacing existing hooks or custom hook settings.
- When applicable, checks run before a push and require a clean checkout. They validate formatting and run offline workspace checks; certain changes or ref conditions may trigger broader validation.
Documentation
- Added guidance on installing and using local checks, their requirements, and limitations. Full workspace validation remains blocked until the pinned GPUI dependency is available.

Walkthrough

The change adds opt-in Git hook installation and pre-push validation. The hook checks pushed refs and checkout state before invoking a script that validates Rust dependencies and runs formatting and locked offline workspace checks. Tests use disposable repositories, and documentation describes setup and limitations.

Changes

Local pre-push checks

Layer / File(s)	Summary
Enable the local hooks `.gitattributes`, `scripts/install-hooks.sh`, `scripts/hooks/test-hooks.py`	The installer checks existing hook settings and active hooks before enabling `.githooks`. Git attributes set LF endings for the specified hook scripts. The test harness checks installer behavior in disposable repositories.
Validate pushes and run checks `.githooks/pre-push`, `scripts/hooks/check.sh`, `scripts/hooks/test-hooks.py`, `docs/local-checks.md`	The pre-push hook validates ref records and checkout state before running checks. The check script validates the Rust environment and dependency state, then runs formatting and locked offline workspace checks. Tests cover hook behavior, and documentation describes setup and limitations.

Merge Risk: Low · up to 776fd

The opt-in pre-push checks are low risk to merge. Fix the documented PowerShell installer command, which points to a missing file, and consider hardening the clean-checkout check and the test environment. Real-workspace acceptance is still blocked by the deleted GPUI dependency, as the PR states.

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 3 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Minor · Functional Correctness · Quick win

Inspect submodule changes when checking checkout state.

If a contributor sets submodule.vendor/gpui-component.ignore=dirty or all, git status can report a clean checkout while that dependency’s source differs from the pushed commit. Once the dependency prerequisites are resolved, cargo check can then validate local source that the push does not contain. Pass --ignore-submodules=none to this status command so the clean-checkout check does not depend on local Git configuration. (git-scm.com)

Remove or supply the PowerShell installer.

The documented pwsh command names scripts/install-hooks.ps1, which is not present at the reviewed revision. A contributor who follows that command cannot install the hooks. Remove the command or add the installer; keep the working Bash/Git Bash instruction. (raw.githubusercontent.com)

Major · Data Integrity & Integration · Quick win

Remove inherited Git repository variables from the fixture environment.

If a Git hook launches this test suite, os.environ can contain GIT_DIR, GIT_WORK_TREE, or GIT_INDEX_FILE. These variables can redirect the fixture’s git add and git commit commands to the calling repository instead of self.root. Clear repository-location variables before the first git init. Git documents this requirement for commands targeting another repository. (git-scm.com) Based on learnings, Git subprocesses targeting a disposable repository must not inherit repository-location variables.
