plan

plan is a skill for Claude Code, Codex from jh941213/codex-lattice. It costs 75 tokens per session (685 once invoked), scanned A, original, MIT.

A planning skill for complex software work involving several implementation steps, files, or architecture decisions.

In plain words
What is it for?
Use it to plan multi-file features, compare implementation options, define testing, and record what will and will not be changed.
Why use it?
It turns a broad request into an agreed scope, approach, ordered tasks, risks, and verification checks before coding begins.

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

plan 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 5d 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

작업 계획 수립

새로운 기능이나 복잡한 작업을 시작하기 전에 계획을 세웁니다.

언제 Plan을 사용하는가

상황 Plan 필요 대신 사용
3단계 이상 구현 O
아키텍처 결정 포함 O
여러 파일 변경 O
1-2줄 수정 X 바로 구현
버그 수정 (원인 명확) X 바로 수정
"무엇을 만들까" 결정 X $prd 사용
기술 명세서 필요 X $spec 사용

계획 수립 프로세스

1. 요구사항 분석

  • 성공 기준 정의 ("완료"란 무엇인가?)
  • 가정과 제약사항 명시
  • 스코프 경계 설정 (하지 않을 것도 명시)

2. 현재 코드 파악

  • 관련 파일/함수 탐색 (Grep, Glob)
  • 기존 패턴과 컨벤션 파악
  • 유사한 구현 검토

3. 접근 방식 비교

  • 최소 2개 방안 제시
  • 각 방안의 트레이드오프 분석
  • 추천 방안 선택 + 이유

4. 작업 분해

각 단계에 포함:

  • 구체적 작업 (파일 경로, 함수명)
  • 의존성 (선행 단계)
  • 예상 복잡도 (Low/Med/High)
  • 검증 방법

5. 위험 요소 + 완화책

계획 확정 후

  1. 사용자 승인 대기
  2. 승인 시 CHECKPOINT.md 생성 (3단계 이상일 때)
  3. 실수 발생 시 즉시 STOP → re-plan (밀어붙이지 않기)

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.

plan is a skill published in the GitHub repository jh941213/codex-lattice (19 stars, last pushed 3mo ago), licensed MIT. It adds 75 tokens to every session and 685 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
