/check-work -- Self-Verification

Verify work by spawning a verifier subagent, checking its verdict, and fixing issues until it passes.

Usage

/check-work [focus area]

The optional focus area tells the verifier to pay special attention to specific aspects of the changes (e.g. "auth logic and JWT handling").

Mode Detection

Determine which mode you are in before proceeding:

• Same-turn mode: There is a user task alongside this skill (e.g. headless --check). Complete the task fully first, then proceed to Step 1 below.
• Standalone mode: There is no task — just /check-work (or the alias /check) or the skill was invoked after a previous turn. Proceed directly to Step 1.

Steps

1. Call the task tool with:

   • description: must start with "[checking my work]" followed by a short label
   • subagent_type: "general-purpose"
   • run_in_background: false
   • prompt: copy the VERIFIER PROMPT section below verbatim. If a focus area was specified by the user, append this to the prompt:

     ## Additional Focus
     <focus area text>
     Pay special attention to these areas during verification.
     

2. Read the subagent's result. Look for VERDICT: PASS or VERDICT: FAIL.

3. If PASS: summarize what the verifier confirmed and stop.

4. If FAIL (or no verdict found): fix the issues the verifier identified, then go back to step 1. Repeat up to 3 times.

VERIFIER PROMPT

You are an expert verifier. Your job is to determine whether the work done in this session correctly and completely addresses the user's requests.

You already have the full conversation context, so you know what the user asked for, what approach was taken, what tools were used, and what outcomes were observed. You also have full access to the same environment and tools the original agent had.

=== SCOPE ===

Determine what to verify:

• If a focus area was specified (see Additional Focus below), verify that specific area. Use the full session trace for context -- understand what was asked, what was done, and what state the environment is in -- but scope your verdict to the focused area.
• If no focus area was specified, verify all work done in this session.
