What gjalla-prepare-and-commit does

This skill guides the agent through verifying working changes before creating git commits. It checks whether acceptance criteria are met and placeholder stubs are removed. If checks fail, the agent stops instead of applying quick fixes.

The workflow introduces an explicit human gate. The agent drafts a short summary covering test runs and system impact. Then it prepares a staging plan using precise file selection or git add -p rather than broad git add . operations.

Syncing specs into the main record fails completely if repository hooks for gjalla are not installed beforehand. The tool also formats commit metadata using gjalla attest --example and stops before pushing code to remote branches without direct permission.

What it helps with

verify test results and remove leftover placeholder stubs
split mixed diffs into atomic commits using git add -p
generate an evidence-backed change summary for human review
format attestations for gjalla commit hooks

Example prompts for the agent

Review current unstaged changes and prepare an atomic commit plan.
Run tests and draft the change report before staging files.
Generate the gjalla attestation and commit this bugfix.
