chore: auto-fix biome on staged files via pre-commit hook#373
Merged
Conversation
Adds a dependency-free git pre-commit hook (.githooks/pre-commit) that runs biome check --write on staged source files and re-stages them, so commits land lint+format clean. Wired through prepare (git config core.hooksPath .githooks, git-guarded so consumer installs are a no-op); uses the biome already in deps — no husky/lint-staged, no lockfile change.

What
Adds a dependency-free git pre-commit hook that auto-fixes biome (lint + format) on staged files and re-stages them, so commits land clean.
.githooks/pre-commitrunsbiome check --writeon staged*.{ts,tsx,js,jsx,json,jsonc}and re-stages them. No-op if biome is absent or nothing relevant is staged.prepare:git config core.hooksPath .githooks(git-guarded, so a consumer's git-dep install is a no-op), then the existingtsupbuild.Why
Matches agent-eval's auto-fix-on-commit behavior without adding the husky/lint-staged toolchain (which would need a lockfile bump on this repo).
Verified
Smoke: staged a badly-formatted file → hook reformatted it (
const a = 2→const a = 2) and re-staged it; the hook's own commit ran clean.
