auto-dev

An automated development pipeline that takes a completed plan through coding and validation. Validation means checking whether the implementation meets its requirements and works as expected.

In plain words
What is it for?
Use it to start or continue planned work, implement its tasks, run validation, and track progress in project work files.
Why use it?
It connects planning, development, and checking into one repeatable workflow and can resume from the current phase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

auto-dev scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

Auto-Dev 스킬

Work 파일과 Task 시스템을 통합하여 Development → Validation 파이프라인을 자동 실행합니다.


Step 0: Work 컨텍스트 + Task 시스템 초기화 [건너뛰기 금지]

진입 확인 [건너뛰기 금지]

Work ID가 제공된 경우, planning-results.md 존재 여부 확인:

ls docs/works/active/W-XXX-*/planning-results.md 2>/dev/null \
  || ls docs/works/idea/W-XXX-*/planning-results.md 2>/dev/null
  • 파일 있음 → 계속
  • 파일 없음 → "planning-results.md를 찾을 수 없습니다. /plan-task W-XXX를 먼저 실행하세요." 출력 후 중단

Work ID 없이 새 요청으로 진입한 경우 (/auto-dev 로그인 기능 추가 형식):

  • work.sh new로 Work 생성 후 → 즉시 /plan-task W-XXX로 위임 (planning-results.md 없이 Step 1 진행 금지)
  • 이는 brainstorming → plan-task → auto-dev 체인 준수를 위함

Fallback 모드(docs/works/ 폴더 자체가 없는 경우)에서는 이 확인을 스킵합니다.

Work ID가 제공된 경우 (예: /auto-dev W-042)

  1. Work 파일 위치 탐색: docs/works/idea/ 또는 docs/works/active/
  2. W-XXX-{slug}/W-XXX-{slug}.mdplanning-results.md 읽기
  3. frontmatter status, current_phase, phases_completed 확인

idea 상태면 자동 전환:

./scripts/work.sh start W-042
# idea/ → active/ 이동, status: active, started_at 기록

current_phase에 따른 시작 위치:

current_phase 시작 위치
planning Step 1부터 전체
development Step 2부터 재개
validation Step 3부터 재개

Work ID가 없는 경우 (예: /auto-dev 로그인 기능 추가)

docs/works/ 폴더 존재 여부 확인:

  • 존재하면work.sh new로 새 Work 생성 후 Step 1부터 진행:
    ./scripts/work.sh new "<요청 제목>"
    
  • 없으면 → Step 4 fallback

Task 시스템 초기화 [건너뛰기 금지]

Work ID 확보 후 반드시 실행:

  1. ToolSearch("select:TaskCreate,TaskUpdate,TaskList") — 스키마 fetch

Task 도구가 없으면 멈추지 말고 대체 경로로 간다ToolSearch가 Task 계열을 반환하지 않는 호스트/세션이 있다(F-038). 그때는 ./scripts/checklist.sh 기반 durable checklist로 추적한다. 규율 SSOT: skills/references/task-tools-fallback.md.

  1. TaskList 실행 → subject가 [W-XXX]로 시작하는 Task 있으면 상태 확인 후 재개 (재생성 스킵, W-XXX는 현재 Work ID)
  2. Task 없으면 → Step 1: Development Tasks 생성으로 이동

Step 1: Development Tasks 생성

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

auto-dev is a skill published in the GitHub repository This-HW/claude-code-kit (4 stars, last pushed 4d ago), licensed MIT. It adds 22 tokens to every session and 4,598 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
