Read-only maintainability audit of a whole codebase — ranks the files most likely to cause maintenance pain (size × churn hotspots, test gaps, lint debt) and proposes discrete fixes, each as its own PR. Use before a cleanup/refactor pass, when inheriting a codebase, or when the user says "유지보수성 점검", "어디부터 리팩토링"…
Skill Claude CodeCodex
Enumerate the full impact set of a symbol before or during a change — every reference, caller, implementation/subtype, and reverse import — plus an explicit list of what could NOT be resolved (dynamic dispatch, reflection, generated code). Use before touching a shared / exported / widely-imported symbol, before an…
Skill Claude CodeCodex
Behavioral guidelines that reduce common LLM coding mistakes — surgical changes, no overcomplication, surface assumptions, define verifiable success, no silent scope creep. Use while writing, reviewing, or refactoring code, or when the user says "코딩 가이드", "수술적으로", "과설계 하지마", "keep it simple".
Skill Claude CodeCodex
Disciplined diagnosis loop for a hard bug or performance regression — reproduce → minimize → hypothesize → instrument → fix the cause → regression-test. Use when something is broken / throwing / failing or regressed, or when the user says "diagnose this", "debug this", "버그 진단", "왜 안 되지", "디버깅".
Skill Claude CodeCodex
Write the live working-set state into a resume block so a FRESH session can continue this work without re-narration. Use when stopping mid-task, or when the user says "handoff", "핸드오프", "체크포인트", "이어서 할 수 있게", "checkpoint". Pairs with /harness-kit:pickup (handoff writes, pickup reads).
Skill Claude CodeCodex
Scan a repository's tech stack and generate a tailored Claude Code harness for it — a thin .claude/CLAUDE.md spine, stack-specific architect agent(s), and specs/ADR scaffolding — fitting the generic harness-kit engine to this repo. Use when setting up the harness in a new or existing repo, or when the user says "set…
Skill Claude CodeCodex
Resolve a change request into an EXACT edit target before touching code, then gate the edit on tests — the localize → edit → validate loop. Use for a bug fix, an issue, or a feature change where the right files/symbols are not already obvious, or when the user says "이거 고쳐줘", "어디를 고쳐야 해?", "fix this issue", "where does…
Skill Claude CodeCodex
Scaffold a spec triplet (spec.md / plan.md / context.md) under specs/YYYYMMDD- / before starting a non-trivial piece of work. Use when a task spans multiple modules / several commits / a new ADR, or when the user says "new spec", "스펙 만들어", "plan this out", "spec this", "기획부터".
Skill Claude CodeCodex
Re-enter in-flight work in a fresh session by reading a resume block a previous session left (the read half of the handoff/pickup loop). Use at the start of a fresh session, or when the user says "pickup", "resume", "이어서", "재개", "어디까지 했지", "continue where we left off".
Skill Claude CodeCodex
Drive a single behavior change with Kent Beck's red → green → refactor loop — write the failing test FIRST, confirm it fails for the right reason, implement the minimum to pass, then refactor. Use when building a feature or fixing a bug test-first, or when the user says "TDD", "red-green-refactor", "테스트 먼저", "실패…
Skill Claude CodeCodex
Create an isolated git worktree for a code-change task (../ - on its own branch), keeping the main checkout clean. Use in a repo that opted into the worktree-per-task workflow, or when the user says "new worktree", "워크트리 만들어", "isolate this task", "task별 worktree".
