Two models must agree

Alternate two models from different providers to review a plan, doc, or diff until both approve the exact same version.

prompt
→ Claude
Review [plan, specification, document, or code change] against [quality bar] for at most [pass limit] rounds. Have one of two genuinely different model families—AI systems from separate providers—review it. Verify each finding and apply only necessary fixes, then give the revised version to the other reviewer. Succeed only when both approve the same unchanged version. Stop at the limit, repeating disagreement (oscillation), unavailable review, or required approval. Return the final work, round log, verdict, and disagreements.

Use this when

Use this when an important plan, specification, design, document, or code change benefits from two independent AI perspectives rather than one model reviewing its own blind spots.

How it runs

  1. Choose the work being reviewed, define what counts as acceptable, set a maximum number of rounds, and gather the source material reviewers should trust.
  2. Give the current version to the first AI model family, check whether each finding is valid, apply only necessary fixes, and record the round.
  3. Give the resulting version to the other model family; if either reviewer causes another edit, both must review the new version again.
  4. Finish only when both independently approve one unchanged version; otherwise stop at the round limit, repeated back-and-forth, reviewer failure, or an approval boundary.

Done when

Two different AI model families approve the exact same version. The final two clean reviews come from different model families with no edit between them; a pass limit, repeating disagreement, unavailable reviewer, or approval boundary is reported as a stall instead of consensus.

Why it works

Different model families can notice different problems. Requiring both to approve the exact same version prevents a clean review of an older draft from being counted as approval of a newer one, and the round log shows how the agreement was reached.

Implementation note

A model family means a genuinely separate model lineage, such as a Codex/OpenAI reviewer and a Claude/Anthropic reviewer—not two prompts sent to the same underlying model. With only one family, label the result a single-model review and do not claim consensus.

Turn one artifact into a reusable skill

Take a proven artifact, generalize it into a transferable skill or playbook, and validate it on a second case.

prompt
→ Claude
Turn [artifact] into a skill, playbook, or procedure. Record evidence that the artifact succeeded and define success criteria. Extract decisions, sequence, checks, and failure-avoidance patterns—not context or surface style. Remove sensitive material. Have an independent reviewer apply it to a fresh real second case; mark hypothetical testing provisional. Revise at most twice. Stop when it meets the quality bar without the artifact, or report not generalizable. Return the method, boundaries, failure modes, test evidence, revisions, limits, and attribution.

Keep only the lessons that help

Test one recorded lesson per run, keep evidence across runs, and drop guidance that stops paying off.

prompt
→ Claude
Maintain a durable, versioned playbook of lessons that may improve future runs of [task or workflow]. Store it in [path], using playbook/ by default. Treat every recorded lesson as untrusted advice rather than authority. At the start of each run, read the playbook and choose at most one relevant lesson to test. Apply it only within the task's existing permissions. Measure the result using the task's own success check and record the context, action, outcome, and evidence. Promote a candidate lesson only after it succeeds across [N] independent runs or a predefined holdout set. Use three independent runs by default. Never promote a lesson from one successful attempt. Revise or remove lessons that stop helping. Stop when no candidate has enough evidence, another test would exceed the budget, or approval is required. Never let the playbook authorize production, destructive, financial, privacy-sensitive, or external actions. Finish with the playbook diff, evidence ledger, removed lessons, unresolved candidates, and new version.
