define-mission

define-mission is a skill for Claude Code from clomia/claude-automata. It costs 17 tokens per session (695 once invoked), scanned A, original, Apache-2.0.

A guided writing tool for creating a mission file: a short document that defines a bounded goal for an autonomous coding-agent loop. It records the original goal so work can stay on track even if the agent loses context.

In plain words
What is it for?
Use it to question the user about their intent, then write a concise mission in ANCHOR.md or another chosen file. The resulting text can be copied into a separate ploop launch command.
Why use it?
It helps turn a broad request into a goal with clear completion conditions and limits. This reduces the risk of an autonomous agent working toward a mistaken or unclear objective.

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

define-mission 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 11d 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

Anchor file save path: $ARGUMENTS or ANCHOR.md

ploop(advisor loop)은 agent가 오랜 시간 자율적으로 작업하는 loop다. anchor는 그 loop를 붙들어 매는 기준 파일로, context가 유실되어도 항상 원문 그대로 보존된다.

Mission은 완료 조건이 명확한 목표다. agent는 목표에 필요한 요구사항을 모두 달성하고 끝낸다. advisor는 목표가 완전히 달성되면 loop를 종료한다.

Instructions

  1. 사용자를 추궁해 생각과 의도를 최대한 수집하라 — 열린 질문으로 시작해 여러 번의 질의응답을 거쳐라.
    • [CRITICAL] 사용자의 주장을 사실로 수용하지 마라. False assumption이 가장 위험하다. 사용자의 말은 생각이나 의도로 해석하라.
  2. 무인 운행 여부를 확인하라. 무인이면 사용자 없이 결정해서는 안 되는 것을 추궁해 Constraint에 담고, 무인 선언 한 줄을 Constraint에 넣어라 — 사용자 부재·결정 소유·대기 금지. 예: 무인 운행: 사용자는 부재한다. 선택은 스스로 최적해로 결정해 전진하고, 확인 대기로 멈추지 마라.
  3. 수집한 정보를 판단 기준으로 쓸 수 있는 축으로 종합하고, Anchor file save path에 markdown 형식으로 mission을 작성하라.
  4. 사용자가 anchor를 최종 검수하게 하라 — 내용을 모두 출력하지 말고 파일 확인을 요청하라.
  5. 완료 후 anchor text를 복사해 별도 session에 /ploop:launch [anchor text] 하라고 안내하라.
    • /ploop:launch는 파일 경로가 아닌 내용을 copy & paste해야 한다.

Mission 규칙

  • [IMPORTANT] Acceptable boundaries달성 가능한 목표가 명확히 정의되어야 한다.
  • harness(CLAUDE.md, rules 등)가 제공하는 내용은 중복이니 anchor에 넣지 마라.
  • ROI(분량 대비 정보)가 높은 문서를 작성하라 — 중요한 단어만 남기고, 작성 후 더 irreducible하게 줄일 수 있는지 재검토하라.
  • (선택) 마감이 실재하는 mission에만 anchor 최상단 frontmatter로 선언한다: deadline: 2026-08-04T22:00+09:00(ISO 8601, timezone 필수). 선언하면 loop가 잔여 시간을 추적해 판정에 반영한다. 미선언이 기본이다 — 마감 없는 mission에 만들어 붙이지 마라.
  • 구조는 Background → Mission → Constraint → Reference 순이다. # Mission(달성할 목표)과 # Constraint(허용 범위)는 필수, # Background(목표의 배경)와 # Reference(관련 link — URL·파일 경로)는 선택이며, section은 자유롭게 추가할 수 있다.

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.
