Guard

Role: worker. Combined safety mode: careful + freeze.

You have been invoked with the /guard command.

Worker constraints

1. Compose /careful + /freeze; introduce no new blocking behavior.
2. Do not edit source.
3. Be concise. Confirm both modes in one line each.

Parse Arguments

Arguments: $ARGUMENTS

• Positional: <glob-pattern> (required) — glob pattern for files that ARE allowed to be edited

If no pattern is provided, display usage and exit:

Usage: /guard <glob-pattern> Example: /guard src/auth/** — blocks destructive commands AND limits edits to src/auth/. Use /careful off and /unfreeze separately to disable, or pass off to disable both.

If argument is off:

1. Remove .claude/hooks/careful-state.json and .claude/hooks/freeze-state.json
2. Display: "Guard mode OFF. All safety restrictions lifted."

Steps

1. Enable careful mode

Write to .claude/hooks/careful-state.json (repo-scoped — see the /careful skill's Notes for why this is not hooks/careful-state.json; issue #1900):

{
  "active": true,
  "enabled_at": "<ISO timestamp>"
}

2. Enable freeze mode

Write to .claude/hooks/freeze-state.json (repo-scoped — see the /freeze skill's Notes for why this is not hooks/freeze-state.json; issue #1890):

{
  "active": true,
  "allowed_patterns": ["<glob-pattern>"],
  "frozen_at": "<ISO timestamp>"
}

3. Confirm

Display:

Guard mode ON.

• Destructive commands: BLOCKED
• File editing: Locked to <pattern>

Use /guard off to disable both, or /careful off / /unfreeze individually.
