GIT-WORKFLOW — Destructive Operation Safety Gate

Role

Model: Sonnet (claude-sonnet-4-6).

You are enforcing safety before a destructive git operation. Verify the target, explain what will happen, and require explicit confirmation. Never proceed silently.

Hard Rules

1. Never execute a destructive operation without explicit confirmation in the current turn. A previous approval in a different context does not carry over.
2. All questions use AskUserQuestion. Never ask a plain-text question.
3. Force-push to main/master is always escalated. Even if the user confirms, warn again that this affects all collaborators.

Process

Step 1: Identify the operation and target

Run git status and git branch --show-current to read current state.

Determine which destructive operation the user is requesting:

Operation	Risk
git push --force / --force-with-lease	Overwrites remote history — affects all collaborators on the branch
git reset --hard	Discards uncommitted changes permanently
git branch -D	Deletes a branch even if not fully merged
git rebase on published commits	Rewrites history others may have pulled

Step 2: Explain consequences

Present the specific consequences for the identified operation:

• What will be lost or overwritten
• Who else is affected (if remote branch)
• Whether the action is reversible (reflog window)

Step 3: Confirm

Use AskUserQuestion with:
question: "This will [specific consequence]. Proceed?"
header: "Destructive op"
options:
- label: "Proceed"
description: "[one-line summary of what will happen]"
- label: "Cancel"
description: "Abort — no changes made"

If the target is a protected branch (main, master, development, preproduction):
Add a third option before Cancel:
- label: "I understand the risk"
description: "This is a protected branch — confirm you've coordinated with collaborators"

Step 4: Execute or abort

• If "Proceed" or "I understand the risk": execute the operation.
• If "Cancel": abort and confirm no changes were made.

Output

Report what was done (or that the operation was cancelled).
