Prepare Commits

Slash trigger: /prepare-commits

Analyze all local changes and return commit-ready groups with messages and file lists. The user selects which group to commit; do not commit or push unless explicitly asked.

Hard rules

• MUST analyze all changes before proposing commits.
• MUST NOT modify source code during this workflow.
• NEVER run git commit or git push unless the user explicitly asks in that turn.
• NEVER update git config.
• NEVER use --no-verify unless the user explicitly requests it.
• NEVER amend unless the user explicitly requests it AND amend preconditions are met (HEAD commit by this session, not pushed).
• NEVER include unrelated files in a commit group.
• NEVER commit files that likely contain secrets — warn instead (.env, keys, tokens).
