simon-healthcheck

simon-healthcheck is a skill for Claude Code, Codex from SW-in-beta/simon-skills. It costs 105 tokens per session (2,579 once invoked), scanned B, original, MIT.

A health dashboard that checks the structure and quality of the simon family of skills. It verifies files, required metadata, triggers, references, and registry entries.

In plain words
What is it for?
Use it to inspect skill status, check changes after a boost, and validate skill files and their linked resources.
Why use it?
It can reveal missing files, broken references, or skills that cannot be reached through the central registry before those problems cause confusion.

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 B, and why

simon-healthcheck scanned grade B with 1 finding 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 11d 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.

simon-healthcheck

simon 패밀리 전체의 구조적 건강 상태를 검증하고 대시보드로 출력한다.

Instructions

Step 1: 대상 스킬 탐색

~/.claude/skills/ 하위에서 simon 패밀리 스킬을 탐색한다:

ls -d ~/.claude/skills/simon*/  ~/.claude/skills/simon-company/ ~/.claude/skills/simon-presenter/ ~/.claude/skills/_shared/ 2>/dev/null

Step 2: 스킬별 검증

각 스킬 디렉토리에 대해 아래 항목을 검증한다:

2-A: SKILL.md 기본 검증
  • 존재 여부: SKILL.md 파일이 있는가
  • YAML frontmatter: name, description 필드가 존재하는가
  • 줄 수: 500줄 이내인가 (경계: 450-500줄이면 WARNING)
  • description 트리거: "Use when:" 패턴이 포함되어 있는가
  • 라우터 Registry 대조 (전역 1회 — 스킬별 총점 아닌 "전역 검증" 섹션에 보고): ls ~/.claude/skills/simon*/SKILL.md 결과(SKILL.md 없는 workspace 디렉토리 제외)와 simon/SKILL.md Registry 표의 스킬명을 대조 — 스킬이 있는데 Registry에 없으면 FAIL (라우터 도달 불가 스킬)
  • CLAUDE.md 참조 실존 (전역 1회 — "전역 검증" 섹션에 보고): ~/.claude/CLAUDE.md가 언급하는 simon-* 스킬명이 실제 디렉토리에 존재하는지 대조 — 유령 참조 발견 시 FAIL
2-B: Reference 검증
  • 참조 경로: SKILL.md의 실제 Markdown 링크 [text](references/file.md) 또는 명시적 read 지시문(read references/file.md)에서 참조하는 경로가 실제로 존재하는가. 오탐 제외 규칙: ① 코드블록(```) 내부의 예시 경로, ② 타 스킬 절대경로(~/.claude/skills/다른스킬/references/...), ③ 예시 텍스트 내 언급 — 이 세 가지는 검증 대상에서 제외한다.
  • 300줄 초과 TOC: 300줄 초과 reference 파일에 TOC(## 목차 또는 ## Table of Contents)가 있는가
  • 미참조 파일: references/ 디렉토리에 있지만 SKILL.md에서 Markdown 링크로 한 번도 참조하지 않는 파일이 있는가
  • 인라인 프롬프트 길이: SKILL.md 본문 내 subagent spawn 프롬프트 블록이 20줄을 초과하면 references/ 분리 권장 (WARN)
2-C: Script/Asset 경로 검증

SKILL.md와 references/*.md에서 참조하는 스크립트·자산 경로가 실제 존재하는지 검증한다.

추출 대상 패턴:

  • 절대 경로: ~/.claude/skills/*/scripts/*.sh, ~/.claude/skills/*/assets/*
  • 상대 경로: scripts/foo.sh, workflow/scripts/bar.sh, assets/template.html
  • bash/python 실행문: bash scripts/..., python3 scripts/..., nohup python3 ~/.claude/skills/...

오탐 제외 규칙 (2-B와 동일): ① 코드블록(```) 내부에서 패턴 예시로만 사용된 경로 (실제 실행 커맨드는 코드블록 안이라도 검증 대상) ② 예시 텍스트 내 언급 ("예: scripts/deploy/" 같은 설명용)

검증 항목:

  • 경로 존재: 참조된 스크립트/자산 파일이 실제로 존재하는가
  • 실행 권한: .sh 파일이 실행 권한(chmod +x)을 갖고 있는가
  • 미참조 스크립트: scripts/ 디렉토리에 있지만 SKILL.md나 references/에서 한 번도 참조하지 않는 파일이 있는가

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.
