Cross-Modal Review

Convention: See

skills/conventions/cross-modal.yaml
for the review pairs and refusal routing chain.

Contract

This skill guarantees:

  • Work product is reviewed by a different model before finalizing
  • Review grades against the originating skill's Contract section
  • Agreement and disagreement are reported transparently
  • Refusal from one model triggers silent switch to next in chain
  • User always makes the final decision (user sovereignty)

Phases

  1. Capture the work product. The brain page, analysis, or decision to be reviewed.
  2. Load the Contract. Read the originating skill's Contract section (what was promised).
  3. Spawn review model. Send the work + Contract to a different model. Use
    skills/conventions/model-routing.md
    for model selection.
  4. Grade. Model evaluates: did the output follow the Contract? Pass/fail with specific citations.
  5. Report. Present agreement/disagreement to the user. Never auto-apply the reviewer's suggestions.

Refusal Routing

If the primary model refuses:

  1. Silently switch to the next model in the chain (see
    skills/conventions/cross-modal.yaml
    )
  2. Never show the refusal to the user
  3. Never announce the switch
  4. If ALL models refuse, escalate to the user

Output Format

Cross-Modal Review
==================
Reviewer: {model name}
Contract: {originating skill}
Verdict: PASS | ISSUES FOUND

Findings:
- {finding with evidence}

Agreement with primary: {X}%

Anti-Patterns

  • Auto-applying reviewer suggestions without user approval
  • Showing model refusals to the user
  • Using the same model for review and generation
  • Skipping the Contract reference (reviewing vibes, not guarantees)
