hyper-waterfall: Instructions file for Codex

AGENTS.md

hyper-waterfall AGENTS.md is an instructions file for Codex, OpenCode from postmelee/hyper-waterfall. It costs 1,380 tokens per session, scanned A, original, MIT.

Repository instructions for coding agents working on a framework that uses the Hyper-Waterfall process. They describe the project, required workflow, naming rules, and approval requirements.

In plain words
What is it for?
Use them when an agent works in this repository or another repository that copies these instructions. They cover issue and branch setup, planning, implementation, verification, reporting, pull requests, and cleanup.
Why use it?
They give agents the local rules they must follow before changing code, including checking manuals and getting approval at defined stages. This prevents work from skipping the project's review and tracking process.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

This is postmelee/hyper-waterfall's own configuration. It tells Codex and OpenCode how to work on hyper-waterfall 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 hyper-waterfall 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

hyper-waterfall 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.

AGENTS.md

본 저장소에서 작업하는 모든 코딩 에이전트(Codex, Claude Code 등)가 따르는 운영 규칙. 매 턴 시스템 프롬프트로 적재되므로 항상 필요한 정책·제약·인덱스만 둔다. 절차 상세는 매뉴얼·SKILL로 분리한다.

프로젝트 개요

본 저장소는 하이퍼-워터폴 방법론을 모듈화한 프레임워크 저장소이며, 자기 자신에게 본 방법론을 적용하는 dogfooding 사례를 운영한다. templates/에는 적용 대상 저장소에 복사할 진실 원천 파일이 있고, 본 저장소 루트의 mydocs/manual과 mydocs/skills는 templates/mydocs/의 동일 폴더로 가는 심볼릭 링크다.

하이퍼-워터폴 핵심 규칙

이 프로젝트는 하이퍼-워터폴 방법론을 적용한다. 에이전트의 기본 동작(빠른 실행, 자율 수정)과 충돌하므로 반드시 숙지한다. 상세: agent_code_hyperfall_rule_conflict.md.

  • 소스 수정 전 반드시 작업지시자 승인 요청
  • 작업은 GitHub Issue 기준으로 추적
  • 새 기능, 버그 수정, 구조 변경은 이슈 -> 브랜치 -> 오늘할일 -> 계획서 -> 구현 -> 검증 -> 최종 보고서 -> PR 순서 절대 생략 금지
  • 각 단계 완료 후 승인 없이 다음 단계 진행 금지
  • 범위가 불명확하거나 기존 작업과 충돌할 가능성이 있으면 먼저 확인
  • 사용자나 다른 작업자가 만든 변경은 되돌리지 않음
  • 이슈 close는 작업지시자 승인 후 또는 PR merge 확인 후에만 수행
  • 문서 수정은 기존 내용을 먼저 읽고 필요한 부분만 수정하며, 불가피할 때만 내용을 추가
  • 작업 완료 후 다음 작업에 필요하지 않은 로컬/원격 부산물은 정리
  • PR merge와 이슈 close 후에는 main으로 돌아오고, 더 이상 필요 없는 local/task{번호} 브랜치와 임시 worktree를 정리

승인 간주 조건: 작업지시자가 같은 스레드에서 "계속 진행", "다음 단계 진행"처럼 명시 지시한 경우에만 해당 단계 승인으로 간주한다.

명명 규칙

  • 마일스톤: M{버전} (예: M100=v1.0.0, M05x=v0.5.x). 문서 파일명은 m{숫자} 소문자 (예: m100)
  • 브랜치: local/task{이슈번호} (작업), publish/task{이슈번호} (main 대상 PR 게시용)
  • 커밋 메시지:
    • 기본형: Task #{번호}: 내용
    • 단계: Task #{번호} Stage {N}: 내용
    • 하위 단계: Task #{번호} [Stage {N.M}]: 내용
    • 보고서 묶음: Task #{번호} Stage {N} + 최종 보고서: 내용
  • 문서 파일명: task_{milestone}_{이슈번호}{_impl|_stage{N}|_report}?.md. 신규 문서는 마일스톤 포함 형식 강제. 상세: document_structure_guide.md
  • 모든 문서는 한국어 작성

핵심 강제 규칙 (변경 전 매뉴얼 확인 필수)

  • templates/ 안의 placeholder 표기(예: {REPO_SLUG})는 그대로 보존한다. 사용자가 자신의 저장소에 적용할 때 치환하므로 본 저장소에서는 치환하지 않는다.
  • SKILL이나 매뉴얼 본문을 변경할 때는 README.md의 "핵심 SKILL"·"도입 후 작업 흐름" 표와 templates/mydocs/manual/task_workflow_guide.md의 "SKILL 호출 표시 안내"를 같은 PR에서 갱신한다.
  • mydocs/skills와 mydocs/manual 심볼릭 링크 대상은 변경하지 않는다(templates/mydocs/skills, templates/mydocs/manual이 진실 원천).

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.
