Find the untested code paths that actually matter, not just the coverage percentage. Use after adding tests.

Capture an architectural decision so the next session (or engineer) knows WHY. Use after any non-obvious technical choice.
Skill Claude CodeCodex
Decide whether to add, keep, or remove a dependency. Use before adding any package.
Skill Claude CodeCodex
Make frontend output look intentional, not AI-generated. Use for any UI work — components, pages, layouts.
Skill Claude CodeCodex
Build a repeatable eval loop that grades agent output with an LLM judge, so prompt/skill changes get scored against a baseline instead of eyeballed. Reuses loopkit's verifier subagent as the grader — do not build a new one.
Skill Claude CodeCodex
Calibrate a reviewer persona with few-shot rubric examples so skepticism stays consistent and doesn't drift lenient over long runs.
Skill Claude CodeCodex
Enumerate every end-to-end feature as strict JSON entries with passes:false, editable-passes-only discipline, and priority order. The ledger fresh-context sessions read to know what's done, what's next, and what they're forbidden to touch.
Skill Claude CodeCodex
Diagnose and fix tests that pass sometimes and fail other times. Use when CI is red intermittently.
Skill Claude CodeCodex
Systematically remove one harness component at a time and measure impact, killing scaffolding that no longer earns its complexity.
Skill Claude CodeCodex
Escalate blocked runs to a human via configured channel or fallback to BLOCKED.md and exit the loop. Use when the loop hits an ambiguous spec, a missing credential, a destructive action needing approval, or 3+ consecutive verify failures on the same task.
Skill Claude CodeCodex
Author idempotent init.sh under 120s plus sibling test.sh, stop.sh, reset.sh, serve.sh with fixed names the harness relies on.
Skill Claude CodeCodex
Validate and constrain untrusted input at the boundary. Use on any handler that accepts external data.
Skill Claude CodeCodex
Find and remove unreachable/unused code safely. Use during cleanup or before a refactor.
Skill Claude CodeCodex
Design the three states every data UI forgets. Use for any component that fetches or lists data.
Skill Claude CodeCodex
Write safe, reversible database migrations for this repo's conventions. Use for any schema change.
Skill Claude CodeCodex
Split the Plan/Act/Verify loop across three model tiers — frontier planner, cheap executor, frontier judge — via env vars read by run.sh.
Skill Claude CodeCodex
Security-review a diff against the OWASP Top 10. Use before merging anything that touches auth, input handling, queries, or external calls.
Skill Claude CodeCodex
Get a PDF into the model without blowing the context window or losing structure. Native PDF beats OCR-then-text for most cases; extract-then-summarize beats native for very long docs.
Skill Claude CodeCodex
Expand a 1-4 sentence product brief into a full spec with a design language, acceptance surface, and an ordered feature list.
Skill Claude CodeCodex
Write a PR description a reviewer can approve fast. Use when opening any pull request.
Skill Claude CodeCodex
Run the fixed 6-step session-opening sequence — pwd, read progress, git log, count remaining features, init.sh, smoke-test last feature — before touching any new work. The orientation ritual that lets fresh-context sessions reconstruct project state in under a minute.
Skill Claude CodeCodex
Cache the parts of the prompt that don't change so a long-running loop stops paying full price on every turn. Use when the system prompt, tool defs, or reference docs are stable across many turns.
Skill Claude CodeCodex
Extract the actual cause from a stack trace instead of pattern-matching the error type. Use on any crash or exception.
Skill Claude CodeCodex
Check whether a README actually lets a stranger run the project. Use on any repo's README before publishing.
