Ambient capture

Install the hook

stn hooks install     # add a post-commit hook that runs `stn glob`
stn hooks uninstall   # remove the stndp hook

The installer writes .git/hooks/post-commit in the current repository. It refuses to overwrite a pre-existing post-commit hook it didn't write, and re-running hooks install is safe.

What it captures

The hook runs stn glob after each commit — the same one-shot capture your agent's SessionStart hook performs. It records this session's git context (branch, commit, recent commits, and your GitHub activity) into the graph and is idempotent: re-capturing the same commit is a no-op, so it only ever writes new context. Unlike checkpoint it carries no human focus and never surfaces in stn resume.

You can also run it by hand any time, or wire it to a different trigger (a login shell, an editor hook):

stn glob              # capture this session's context once (idempotent)
stn glob --no-github  # skip the GitHub activity lookup (no network)
stn glob --force      # re-capture even if nothing changed
