Claude Code plugin for feature development (/feature: TDD Generator-Evaluator with Plan-Contract-Test-Build-Evaluate-Integrate-Learn cycle and prior art research), codebase improvement (/improve: iterative audit → Priority 1-2 auto-fix via category-split PRs → plateau detection), and autonomous build pipelines (/build: cmux pane + codex CLI orchestration with workspace isolation).
Scans a codebase for improvement opportunities across 9 categories, classifies each by Priority (1-5), and emits an audit-report.md. Read-only, deterministic, and never dispatches other agents.
Sprint contract 협상 agent. Plan과 project profile을 읽고, 피처에 맞는 hard thresholds, 검증 시나리오, 완료 기준을 정의하여 contract.md를 생성.
4축 디자인 평가 agent. 자기 칭찬 편향 없이 객관적으로 Design Quality, Originality, Craft, Functionality를 평가하고 contract 기준 대비 PASS/FAIL 판정.
Applies Priority 1-2 auto-fixes for a single category to a new branch. Runs tests/lint/typecheck after each batch, binary-search rollback on failure.
Creates a PR from an applier-prepared branch. Detects commit convention, builds PR body with metrics, handles gh CLI unavailability gracefully.
GStack + GSD + Superpowers + build-loop을 cmux pane + codex CLI 기반으로 통합하는 자율 빌드 파이프라인. /build <topic> 한 줄로 spec → 페이즈 분해 → TDD 루프 → 통합까지 진행. claude orch가 plan/refactor를 담당하고 long-lived codex worker가 코드 작성. 컨텍스트는 /compact로 관리.
Iterative codebase improvement orchestrator. Audits → prioritizes → auto-fixes Priority 1-2 via category-split PRs → tracks plateau across iterations. Independent of harness-orchestrator.
피처 개발 하네스 오케스트레이터. /feature 명령으로 TDD 기반 Plan-Contract-Test-Build-Evaluate-Integrate-Learn 사이클을 실행. /feature --init, /feature --resume, /feature "설명" 을 요청할 때 사용.

Claude Code 용 multi-skill plugin. 세 가지 자율 워크플로우를 제공:
/feature — TDD Generator-Evaluator 로 단일 feature 를 plan → contract → test → build → evaluate → integrate → learn 사이클로 처리/build — cmux pane + codex CLI 기반 6-stage 자율 빌드 파이프라인 (그린필드 / 큰 리팩토링용)/improve — 기존 코드베이스의 audit → prioritize → auto-fix → verify 4-phase 개선 루프claude plugin marketplace add gprecious/harness
claude plugin install harness@harness
업그레이드:
claude plugin marketplace update harness
claude plugin uninstall harness && claude plugin install harness@harness
/feature — Feature Development (v0.1.0+)# Initialize harness for a project (profiles tech stack, design system, conventions)
/feature --init
# Run feature development pipeline
/feature "description"
# Resume interrupted feature run
/feature --resume
/build — Autonomous Build Pipeline (v0.5.0+)cmux + codex CLI 위에서 동작하는 6-stage 자율 빌드. claude orchestrator (현재 세션) 가 plan/spec/refactor 담당, long-lived codex worker 가 cmux pane 안에서 test code/구현 담당. v0.6.1+ 부터 dedicated cmux workspace 가 자동 생성·정리됩니다 (사용자 focused workspace 무영향).
# 새 run
/build "add user auth flow"
# checkpoint 없이 풀-오토
/build "topic" --checkpoint=none
# 디버깅용으로 종료 후 cmux workspace 살려두기
/build "topic" --keep-workspace
# Run 관리
/build --resume <run-id>
/build --status
/build --list
/build --gc 30

/build 의 외부 의존성/build 만 사용하는 경우에도 다음을 따로 설치해야 합니다:
brew install cmux jq git gh bats-core
npm install -g @openai/codex
git clone --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack \
&& (cd ~/.claude/skills/gstack && ./setup --no-prefix)
npx -y get-shit-done-cc@latest --global --claude
claude plugin marketplace add tyroneross/build-loop
claude plugin install build-loop@build-loop
claude plugin install superpowers@claude-plugins-official
claude plugin install ralph-loop@claude-plugins-official
/improve — Codebase Improvement (v0.3.0+)Independent from /feature. Use /improve to iteratively improve an existing codebase through a 4-phase audit-prioritize-apply-verify workflow. Auto-fixes safe Priority 1-2 issues (dead code, magic literals, cognitive complexity reduction) into category-split PRs; reports Priority 3-5 structural/design suggestions for manual review.
/improve --init — First-time setup. Detects environment, runs web research, generates 5 project-specific reference docs/improve — Full workflow: audit → prioritize → apply fixes → verify/improve --audit — Audit only, no fixes/improve --apply — Apply last audit's Priority 1-2 fixes as category-split PRs/improve --category <name> — Restrict to one category (e.g. dead-code)/improve --verify — Re-audit to check progress against previous iteration; detects plateau/improve --resume — Recover from interrupted iterationdocs/code-improver/references/ — 5 project-specific reference docs (refreshed monthly)docs/code-improver/code-improver-state.md — Persistent statedocs/code-improvement/YYYY-MM-DD/iteration-N.md — Per-iteration reports with auto-fixes and suggestionsdocs/code-improvement/YYYY-MM-DD/summary.md — Cumulative report (generated on plateau).code-improver-ignore — Project-root glob rules (similar syntax to gitignore)docs/code-improvement/YYYY-MM-DD/events.jsonl (v0.4.0+) — Append-only structured event log used by plateau detection and crash recoverydocs/plans/2026-04-16-code-improver-design.md (parent repo)docs/plans/2026-04-16-code-improver-impl.md (parent repo)/feature 가 의존하는 외부 plugin:
/build 의 외부 의존성은 위 "/build 의 외부 의존성" 섹션 참조 (cmux, codex, gstack, gsd, build-loop, ralph-loop 등). /improve 는 별도 외부 plugin 없이 동작합니다.
