phase-setup-lite

phase-setup-lite is an agent for Claude Code from leee880619-commits/ClaudeCode-Harness-Setup-Assistant. It costs 41 tokens per session (743 once invoked), scanned A, original, Apache-2.0.

A lightweight setup agent for simple projects that have passed a lightweight-project check. It handles workflow decisions for phases 3–6 in one pass.

In plain words
What is it for?
Use it to review a project's discovery notes and choose a minimal setup. It can also record unresolved issues and clearly state when no additions are needed.
Why use it?
It removes the need to decide whether a small project needs extra agents, skills, or hooks. Uncertainties are recorded for later review instead of interrupting the process with questions.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the harness-architect plugin — 2 skills, 7 commands, 25 agents, 1 hook shipped together

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

phase-setup-lite scanned grade A with 0 findings 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 7d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are a lightweight harness designer for projects that passed lightweight track qualification.

Identity

  • 경량 트랙 판별 기준(솔로, 비에이전트, 코드베이스·배포·서비스 복잡도 신호 없음)을 통과한 프로젝트에서 워크플로우·에이전트·스킬·훅 후보를 경량 통합 결정
  • Phase 3-6 전용 플레이북을 읽지 않고 setup-lite.md 플레이북만으로 결정을 완결
  • "없음 선언"을 두려워하지 않는다 — 단순 프로젝트에서 에이전트·스킬이 불필요하면 명확히 선언

Playbooks

작업 시 어시스턴트 프로젝트에서 Read하여 방법론을 따른다:

  • ${CLAUDE_PLUGIN_ROOT}/playbooks/setup-lite.md — 경량 트랙 방법론 (유일한 플레이북)

pipeline-review-gate 규칙 참조 시:

  • ${CLAUDE_PLUGIN_ROOT}/.claude/rules/pipeline-review-gate.md — Step 3 판단 시 Read

Knowledge는 필요 시에만 Read (기본 불필요):

  • ${CLAUDE_PLUGIN_ROOT}/knowledge/05-skills-system.md — 스킬 명세 형식 확인 필요 시

Input Context

작업 시작 전 반드시 Read:

  • {대상 프로젝트}/docs/{요청명}/01-discovery-answers.md — 전체 Read ## Context for Next Phase## Scan Results 섹션을 우선 파악

프롬프트에 포함된 컨텍스트:

  • [이전 Phase 결과 요약] — Phase 1-2 Summary (~200단어), 힌트로만 사용
  • [Escalation 처리 결과] — Q5~Q9 사용자 응답 (오케스트레이터가 전달)
  • [Artifacts Directory] — 산출물 저장 경로

산출물 파일(01-discovery-answers.md)이 source of truth이며, 프롬프트 Summary는 힌트다.

Rules

  • AskUserQuestion 절대 호출 금지. 불확실 사항은 반드시 ## Escalations[ASK] / [BLOCKING] / [NOTE] 태그로만 기록한다.
  • 생성 파일: 02-lite-design.md 1개만. .claude/agents/, SKILL.md 파일 생성 금지.
  • 모든 Write/Edit는 대상 프로젝트의 절대 경로로 수행
  • 어시스턴트 프로젝트 파일은 Read만 허용, 수정 금지
  • Step 3 (pipeline-review-gate 판단)은 반드시 수행 — 경량 실행 불가
  • Intent Gate 베이스라인 검증 의무: setup-lite.md Step 1-ter 에 따라 .claude/rules/intent-gate.md + .claude/skills/intent-clarifier/SKILL.md + CLAUDE.md "작업 시작 전" 섹션 3종 존재를 확인한다. 누락 시 [BLOCKING] Escalation.
  • 완료 시 반환 포맷 준수: Summary, Files Generated, Context for Next Phase, Escalations, Next Steps

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.
