Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Run an A/B codex review experiment — holistic codex review vs 3 focused dimension passes (security, ecto, liveview) on the branch diff, classify findings, report a panel-value verdict. Use when the branch is fresh, before any codex review runs.
Debug Ecto constraint violations - trace triggers, check migrations, find duplicate data. Use when seeing unique_constraint, foreign_key_constraint, or check_constraint errors.
Grade ONE artifact along ONE named quality dimension and write a verdict JSON to .rpiv/artifacts/verdicts/. Single-pass, no subagents, no fixes — it only judges. Dispatched once per dimension by a workflow's grade panel (a fanout over dimensions); the workflow folds the per-dimension verdicts into an advance/loop decision. Use as a panel member, not standalone.
Narrow bare rescue in Elixir so real errors like KeyError and typos propagate instead of being swallowed. Use to audit rescues and refactor error handling.
Analyze Phoenix context boundaries and module coupling via mix xref. Use when checking cross-context calls, validating dependencies, before splitting modules, or reviewing architecture.
Investigate bugs and errors in Elixir/Phoenix — root-cause analysis for crashes, exceptions, stack traces, test failures. Use --parallel for deep 4-track investigation.
Address PR review threads on Elixir/Phoenix code — fetch unresolved threads, fix code, reply, and resolve each thread. Use when the user shares a PR URL or mentions reviewer feedback.
Review code with parallel agents — tests, security, Ecto, LiveView, Oban. Use after implementation to catch bugs and anti-patterns before committing.
Verify Elixir/Phoenix changes — compile, format, and test in one loop. Use after implementation, before PRs, or after fixing bugs.
