review-crucible

description

This skill should be used when the user asks to "review this PR", "grill this PR", "deep code review", "pre-merge review", "find bugs in this diff", "check this branch before merge", "check tests", "check error handling", "check comments", "check types", "check project rules", "check prior PR comments", "simplify this change", or wants a strict high-signal review of pull requests, diffs, branches, or recent changes covering project rules, bugs, tests, errors, security boundaries, types, comments, prior PR discussion, design challenge, and simplification. Use this when correctness matters more than speed and findings must be validated before reporting. Do not use for one-off style nits, single-file readability passes unrelated to recently changed code, or generation of new features.

Review Crucible

Review Crucible is a source-neutral review workflow for Claude Code, Codex, and Amp. Its behavior is defined by the canonical references in references/. Load only the references needed for the task.

Operating Contract

Review changed behavior, invariants, and integration contracts.
Apply local project instructions before generic guidance.
Treat false positives as review debt; validate before reporting.
Separate correctness/safety review from simplification.
Prefer review quality over latency and cost. Follow references/model-policy.md so review passes use the strongest verified host model and the highest supported effort.
Use current documentation when a finding depends on external library, framework, SDK, API, CLI, build-tool, or cloud-service behavior.
Preserve author intent unless it conflicts with security, data integrity, or explicit project rules.

Required References

references/review-orchestration.md: scope discovery, pass selection, targeted activation, host routing, and validation ownership.
references/reviewer-roles.md: canonical behavior for each reviewer role.
references/review-rubric.md: severity, confidence, false-positive filters, validation gate, and output format.
references/agent-roster.md: role names and host check/agent mapping.
references/model-policy.md: strongest-model and highest-effort defaults.
references/compatibility.md: Claude Code, Codex, and Amp limits.
references/github-commenting.md: inline PR comment discipline.
references/rust-best-practices-integration.md: Rust handoff rules.

Workflow

Establish scope: PR, branch diff, commit range, named files, or recent git changes.
If PR metadata exists, run the preflight gate from reviewer-roles.md.
Read applicable AGENTS.md, CLAUDE.md, contribution, testing, release, and language/framework instruction files.
Summarize intended behavior and classify changed files by risk area.
Select passes using review-orchestration.md.
Run focused reviewers in parallel when the active host supports and permits subagents; otherwise run the same passes sequentially.
Validate candidates through finding-validator or parent/orchestrator logic when the host cannot run a validator subagent.
Report only through review-rubric.md.
Post GitHub comments only when requested, following github-commenting.md.
Run simplification only after correctness/safety review, following reviewer-roles.md#code-simplifier.

Host Notes

Claude Code: plugin commands and agents/*.md can launch focused reviewers. The generated agents preload this skill so references are available.
Codex: install this skill and .codex/agents/*.toml custom agents for reviewer fan-out. Codex only spawns subagents when explicitly asked.
Amp: install .agents/checks/*.md and the Amp AGENTS.md snippet. Amp checks run as separate review subagents, but the parent thread owns final deduplication, validation, fixes, and comment posting.

If a host cannot access a reference at runtime, say which reference was unavailable and continue only within the documented host limit.
