Independent peer review via Claude. Translates a natural-language review request into a Claude-specific prompt so invocations stay implementation-agnostic.
Extract from the current context:
If no reviewable material is available, stop and state that material is required.
Assemble a prompt for Claude:
$claude-print SkillRun the $claude-print skill in read-only mode with the assembled prompt.
Compare Claude's output against the reviewed material and the dimensions and structure requested in Step 2, then classify it into one of three branches:
request_user_input to ask the user whether to retry peer review now (transient Claude errors like usage limits often clear within minutes) or proceed with the partial findings. State what is missing so the user can decide."request_user_input to ask the user whether to retry peer review now (transient Claude errors like usage limits often clear within minutes) or proceed without peer review."Do not synthesize peer findings locally to fill a gap. Peer review's value is independence; locally written findings labeled "peer" mislead the consumer.
Then call update_plan to mark this step completed and continue with the next step of the active workflow.
$peer-review is the stable abstraction. Pipeline skills should not call $claude-print directly unless they need raw Claude print-mode behavior.| Case | Status | Duration (ms) | Turns | Tokens | Tool calls | ||||||||

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted, and 20 counted toward the lift figure. The other 3 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +43 percentage points is the difference between those two pass rates over the 20 comparable cases. 1 case got worse with the skill loaded, and it is included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
| Model | Method | Date | Lift |
|---|---|---|---|
| gemini-3.6-flash | verified | 8/21/2026 | +14% |
