| description | Create a git commit with hunk-level staging, diff-scope verification, and sandbox-bypassed signed commit execution. Use whenever the user asks for a commit, especially when the working tree contains a mix of related and unrelated changes. |
Create a git commit while keeping unrelated changes out of it and ensuring the commit is signed.
Workflow
1. Survey the working tree
Run git status and git diff --staged (and git diff for unstaged changes) to enumerate everything that could end up in the commit.
2. Stage hunks with git-surgeon and verify the diff
Use the git-surgeon skill for hunk-level staging/unstaging/splitting. Avoid git add . / git add -A (the harness denies them) and avoid coarse git add <file> when a file contains a mix of related and unrelated hunks. After staging, re-run git diff --staged and compare against the user's stated intent — if any hunks are unrelated, surface them and confirm with the user before continuing instead of bundling unrelated work into the commit.
3. Compose the commit message
Base the message on the staged diff itself, not on the user's wording of the request. Treat the reader as someone seeing this commit for the first time with no knowledge of the conversation — include only the information they need to understand what changed and why. Drop instruction-flavored phrasing, task framing, or context that lives only in the prompt.
4. Commit outside the sandbox
Execute git commit with dangerouslyDisableSandbox: true. Commit signing requires access to gpg-agent / signing keys that the sandbox blocks, so a sandboxed commit would either fail or silently produce an unsigned commit.
5. Confirm
Run git status to verify the commit landed and the working tree is in the expected state.
