claude-code-kit: Instructions file for Codex

AGENTS.md

claude-code-kit AGENTS.md is an instructions file for Codex, OpenCode from This-HW/claude-code-kit. It costs 5,154 tokens per session, scanned A, original, MIT.

A project instruction file that gives coding agents shared rules for planning, implementation, quality checks, and completion.

In plain words
What is it for?
Use it to define agent behavior, require plans and verification before completion, and document limits of the rules copied from claude-code-kit.
Why use it?
It gives different coding agents the same project workflow and records which rules are automatically generated versus project-specific.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is This-HW/claude-code-kit's own configuration. It tells Codex and OpenCode how to work on claude-code-kit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-code-kit configures →

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

claude-code-kit AGENTS.md 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 1mo 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.

이 파일의 cck: 마커 블록은 자동 생성된다. 재생성: ./scripts/export-harness.sh (플러그인 사용자는 /harness-export 스킬 참조) 마커 블록 밖의 내용은 생성기가 건드리지 않는다 — 프로젝트 고유 규약을 자유롭게 적어라.

claude-code-kit — 하네스 중립 규범

이 절은 자동 생성된다. 위아래의 cck 주석 마커 사이는 재생성 시 통째로 교체되고, 그 밖은 생성기가 건드리지 않는다. 갱신은 /harness-export 스킬(또는 kit 레포에서 ./scripts/export-harness.sh). 손으로 고치면 드리프트 검사가 막는다.

이 절은 claude-code-kit의 규범을 원문 그대로 옮긴 것이다. Claude Code·Codex·OpenCode·Copilot·Pi·Hermes 등 이 파일을 읽는 모든 에이전트에 동일하게 적용된다.

워크플로 체인

brainstorming  →  plan-task  →  auto-dev
   (설계·스펙)     (구조화 계획)   (구현 + 검증)

각 단계는 앞 단계의 산출물 없이 시작하지 않는다. 완료 선언 전에는 프로젝트의 검증 명령을 실제로 실행하고 그 출력을 근거로 삼는다 (아래 definition-of-done).

이식된 룰

rules/code-quality 호스트 무관

이 파일이 이식하지 못하는 것 (정직한 한계)

영역 이유
훅 (protect-sensitive · stop-validator · auto-format) Claude Code 훅 런타임 전용 — 다른 하네스에는 실행 지점이 없다
서브에이전트 정의 (33종) Claude Code 서브에이전트 규격 전용
룰 본문의 kit-레포 전용 명령 (scripts/verify-done.sh 등) "요약 금지 / 원문 그대로" 정책의 대가 — 각 룰이 "이 레포에선"으로 한정하고 있으니, 당신 프로젝트의 해당 명령으로 읽어라

rules/mcp-usage Claude Code 고유 프리미티브에 종속
rules/parallel-worktree Claude Code 고유 프리미티브에 종속
rules/task-resume Claude Code 고유 프리미티브에 종속

즉 다른 하네스에서 이 규범은 규율 문서로 동작하지 강제 장치로 동작하지 않는다. 강제가 필요하면 그 하네스의 네이티브 수단(pre-commit 훅, CI)에 같은 검사를 걸어라.

비신뢰 텍스트 취급 (모든 하네스 공통)

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.
