# Commit
Use `check` to verify staged work, `message` to propose or validate its message,
or both when a commit is requested.
## Scope and Checks
1. Inspect `git status --short`, `git diff`, and `git diff --cached`. Stage only
the requested change; preserve unrelated worktree and staged content.
2. Follow [development and verification](../../../CLAUDE.md#development-and-verification)
for the affected files, workspaces, generated outputs, and runtime consumers.
Read the matching [testing guide](../../../docs/testing.md) when behavior
changes.
3. Run applicable formatting, lint/static analysis, type checks, and tests.
Await each heavy check; run one Vitest or Cargo check at a time.
4. Fix actual failures. After checks pass, repeat them only if a new change,
failure, or unresolved concern warrants it. Documentation does not require
unrelated language suites.
`lefthook.yml` is the staged-file hook configuration. Hooks do not replace
behavior verification. For local Rust `ENOMEM` failures, check for competing
compiler/linker processes and retry once with `CARGO_BUILD_JOBS=1`; investigate
actual compiler failures separately. Do not delete installed dependencies as a
generic response to a slow hook.
## Message
Use `<type>[optional scope]: <description>`. The authoritative rules and allowed
types are in [commitlint.config.mjs](../../../commitlint.config.mjs): lowercase
type and subject, no final period, and at most 100 header characters. Use an
imperative description of the actual change.
Examples:
- `feat: add agent sharing`
- `fix(api): preserve webhook idempotency`
- `docs: simplify testing guidance`
Choose the type from the change, not from a desired version bump. See
[release behavior](release-triggers.md) when release impact matters.
Before committing, review the complete staged diff and relevant check results.
Report the commit SHA, scope, and validation; distinguish failed or unrun checks
from passes. Push or open a PR when requested by the caller.
