Git drift hook

Keep committed harness files honest by installing a git pre-commit hook that runs the drift gate on every commit.

Install

adept hook install                 # fail mode (default)
adept hook install --mode fix      # auto-fix mode

This writes .git/hooks/pre-commit. The installed hook is a thin stub that execs adept hook run — all the logic stays in the CLI.

You can also install it at init time:

adept init --git-hook              # bare flag == fail mode
adept init --git-hook=fix

Modes

Mode	Behavior on drift
fail (default)	The commit is blocked; you fix drift and re-commit.
fix	adept auto-adopts / re-renders the drift and re-stages the files, then the commit proceeds.

Under the hood, fix mode runs adept hook run --fix.

Safety

• adept only overwrites a pre-commit hook it wrote itself (marked with an internal adept-managed marker). It refuses to clobber a hand-written hook — remove it or install manually if you already have one.
• The hook assumes a standard .git/ directory. In a worktree or submodule (where .git is a file pointing elsewhere), install the hook manually.
• The installed hook calls adept from $PATH — that’s the install-time contract, so make sure adept is on the PATH of whoever commits.

Running the gate manually / in CI

The same gate the hook invokes:

adept hook run           # fail on drift
adept hook run --fix     # auto-adopt/re-render and re-stage

For CI, prefer adept status, which exits 2 when anything is out of sync:

adept status || echo "drift detected"
