git log shows which commits an agent made.
Will they see the notes? On the pull request, yes, through the gitvow action. Notes are pushed automatically by the pre-push hook; GitHub’s own UI does not show git notes.
Can an agent turn the gate off? Editing the policy or the hook settings requires confirmation under the default policy, and a missing policy fails closed. A determined human can, of course; the gate is for agents.
What happens if a hook crashes? Claude Code treats exit codes other than 0 and 2 as non-blocking errors and continues. gitvow only exits 2 deliberately; a crash in the policy path is caught and turned into a block. The one failure this does not cover is a hook command that cannot be found at all, which is why a per-user install records the absolute path of the executable; see Install.
Can I get back what the agent had before I changed it? Yes. Every agent edit takes a snapshot under a session ref; gitvow snapshots, gitvow diff and gitvow restore list, compare and check one out into a scratch worktree. Code only; the conversation stays local. See Snapshots.
Why not store the transcript? Because it contains tool output, and tool output contains whatever the agent read. See What stays out of git.
Does it work with rebase and squash? Rebase and amend, yes: trailers are in the message and survive on their own, and install sets notes.rewriteRef so notes follow the rewritten commit. Squash, only partly. A squash creates a new commit that git does not treat as a rewrite of the old ones, so the notes do not follow it (tested; earlier versions of this page said otherwise). The trailers survive only if the squash message keeps the original messages, which forges do by default and people edit. Since 0.29 the GitHub Action carries the notes onto the squash commit when the pull request is merged (gitvow carry, run on the closed event with contents: write), and every reader finds a note on a commit whose message lost the trailer by scanning the session refs. gitvow report --decisions-summary still writes the decisions into the pull-request description, so the record survives even where the Action does not run.
Two agents in one repository at once? Each session writes its own notes ref, refs/notes/gitvow/<session-id>, so they never contend, and pushing notes from many machines never conflicts.
Which agents? Claude Code, verified in real sessions. Codex CLI, Gemini CLI, Cursor, Copilot CLI and Factory through adapters built against their documented hook contracts; see Codex, Gemini and Cursor.
