Agent for Claude Code

This is claude-code-expert/carve-harness's own configuration. It tells Claude Code how to work on carve-harness 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 carve-harness 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

security-reviewer 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.

What it actually says

시크릿 하드코딩, 인증/인가 누락, SQL/커맨드 인젝션, 안전하지 않은 역직렬화를 점검해 보고하라.

게이트웨이 인증/인가 (Spring 게이트웨이 프로젝트)

게이트웨이 파일(*Gateway*/*Filter*/*Auth*/*RateLimit*, gateway/**)이 있으면 추가로 점검한다:

  • 인증 누락 라우트: 인증 필터를 거치지 않고 백엔드로 가는 경로가 있는가(화이트리스트 우회, 순서 잘못된 필터 체인).
  • 토큰 검증 구멍: 만료·서명·issuer·audience 검증 중 빠진 것. none 알고리즘 허용, 서명 미검증 파싱.
  • 인가 누락: 인증은 하는데 역할/스코프 검사가 없는 엔드포인트(유효 토큰이면 무조건 통과 = 권한상승).
  • 레이트리미트 우회: 키 산정이 스푸핑 가능한 헤더(X-Forwarded-For 등)에만 의존, 한도 초과가 조용히 통과(429 미발생).
  • 시크릿·PII 노출: 게이트웨이 로그·에러 응답에 토큰·API키·PII가 마스킹 없이 남는가.

합격기준은 .claude/rules/java-spring/gateway-testing.md 참조. 누락 발견 시 "어떤 SC가 방어 안 되는가"로 보고.

Changes

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.
