Actions And Git Hooks

Actions And Git Hooks

An action is a command that rtunk runs on demand or when a git event fires, such as pre-commit. List actions with rtunk actions list, enable them, then install the hooks with rtunk git-hooks sync.

$ rtunk actions enable trunk-check-pre-commit
$ rtunk git-hooks sync
installed: pre-commit

List actions

$ rtunk actions list
Available (not enabled)
  ◯ buf-gen                      Run 'buf generate' anytime a .proto file changes. ...
  ◯ commitlint                   Enforce git commit message standards
  ◯ go-mod-tidy                  Runs go mod tidy when changes are detected to go.mod
  ...

Enable one with: rtunk actions enable <id>

Actions are grouped as Enabled and Available (not enabled). --format json prints the same data as JSON.

Enable and disable actions

rtunk actions enable trunk-check-pre-commit go-mod-tidy
rtunk actions disable go-mod-tidy

Both commands edit .rtunk/rtunk.yaml. Disabling moves the id from actions.enabled to actions.disabled:

actions:
  enabled:
    - trunk-check-pre-commit
  disabled:
    - go-mod-tidy

As with linters, rtunk actions enable without ids opens the same full-screen interactive picker (terminal only; type to filter, space toggles, enter confirms, esc or ctrl-c cancels).

Install git hooks

rtunk git-hooks sync writes a hook script into .git/hooks/ for every git hook that an enabled action triggers. The script calls back into rtunk (rtunk actions run --hook <hook>), so a hook runs every enabled action bound to it.

$ rtunk git-hooks sync
installed: pre-commit
$ rtunk git-hooks unsync
removed: pre-commit

sync is idempotent: running it again rewrites the same files. unsync removes only hooks that rtunk installed.

Note

rtunk never overwrites a hook it did not write. sync prints skipped (foreign hook, use --force): pre-commit and leaves the file alone; add --force to replace it.

The hook script embeds the path of the rtunk binary that ran sync. Re-run sync after moving or reinstalling rtunk.

Run actions

Run one action by id, or every action a git hook triggers:

rtunk actions run trunk-announce
rtunk run trunk-announce
rtunk run --hook pre-commit

rtunk run is a shortcut for rtunk actions run. Arguments after -- are forwarded to the action. Only enabled actions run: rtunk run go-mod-tidy fails with unknown action "go-mod-tidy" while that action is disabled. A failing action makes the command fail:

$ rtunk run trunk-announce
rtunk: actions: trunk-announce: exit code 109

Review past runs

$ rtunk actions history
2026-10-01T09:40:18+02:00  trunk-check-pre-commit  pre-commit  exit 1  434ms
2026-10-01T09:40:17+02:00  trunk-announce          manual      exit 109  535ms

Each line shows the time, the action, what triggered it (manual or the git hook), the exit code and the duration. Filter with --id <action-id> and cap the output with --limit (default 20).
