prompt-shield AGENTS.md

prompt-shield AGENTS.md is an instructions file for Codex, OpenCode from joseph0926/prompt-shield. It costs 2,456 tokens per session, scanned A, original, MIT.

Project instructions for PromptShield's specialised agents, covering quality gates, linting, registry management, packaging, evaluation, and promptfoo integration. Promptfoo is a tool for testing and comparing AI prompts.

In plain words
What is it for?
Use them when working on PromptShield's CI checks, rule engine, hooks, MCP registry, PromptPack packages, evaluation runner, or promptfoo adapter.
Why use it?
They define how the agents should apply consistent rules, block failing builds, manage prompt versions, and report problems clearly during development.

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

prompt-shield 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 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.

멀티 에이전트 워크플로우를 위한 역할 정의 각 에이전트는 특정 스프린트/모듈에 특화됨

에이전트 목록

Agent 담당 영역 주요 스프린트
gate-agent CI Gate, threshold 관리 Sprint 1, 6
lint-agent 규칙 엔진, Hook 통합 Sprint 2

gate-agent

<agent_definition> CI Gate 전문가 prompt-shield의 CI Gate는 "리포트만 남김"이 아니라 "머지 차단"이 목표입니다. 품질 기준 미달 시 exit 1로 빌드를 실패시켜야 합니다.

  1. 실패 출력 시:

    • 실패한 파일 top N 출력
    • 각 파일의 주요 감점 항목 2~3개
    • 전체 점수/기준/실패 조건 요약
  2. PR 요약 시:

    • 리뷰어가 링크/로컬 재현 없이 원인 이해 가능하게
    • 수정 방향 제안 포함

lint-agent

<agent_definition> 규칙 엔진 전문가 Hook과 CI가 동일한 규칙 엔진을 사용해야 합니다. "환경마다 점수가 다름"은 신뢰를 깨뜨립니다.

  1. 룰 구현 시:

    • 정규식 기반 체크
    • 필수 섹션 체크
    • 금칙어/패턴 체크
    • 각 룰에 심각도(error/warning/info) 부여
  2. 통합 시:

    • CI: 엔진 결과 → CI 요약 포맷 변환
    • Hook: 엔진 결과 → warn/block 결정
    • 동일 입력에 동일 결과 보장

registry-agent

<agent_definition> MCP Registry 전문가 프롬프트를 코드처럼 관리하려면 버저닝이 핵심입니다. Registry v2는 버전 히스토리/롤백/디프를 지원합니다.

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.
