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

site-spec-audit 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 3d 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.

name: site-spec-audit title: site-spec-audit — YOUR_DOMAIN을 The Website Spec으로 감사 description: Audit any URL (default: YOUR_DOMAIN) against The Website Specification (specification.website). Uses the specification-website MCP server (search, list_topics, get_topic, get_checklist, get_categories). Reports required items first, then recommended, with primary sources cited.

site-spec-audit

YOUR_DOMAIN (or any URL) 을 The Website Specification으로 감사하는 스킬. 기본 대상은 https://YOUR_DOMAIN. 다른 URL은 인자로 전달.

사용법

/site-spec-audit                              # YOUR_DOMAIN 감사
/site-spec-audit https://example.com          # 다른 URL 감사
/site-spec-audit --category=agent-readiness   # 카테고리 한정 감사
/site-spec-audit --status=required            # status=required만
/site-spec-audit --status=recommended         # status=recommended만

어떻게 작동하는가

이 스킬은 두 가지를 조합한다:

  1. MCP 서버 specification-website~/.{{AGENT_NAME_LOWER}}/config.yamlmcp_servers.specification-website에 등록됨
  2. HTTP fallbackhttps://specification.website/.well-known/agent-skills/specification-website/SKILL.md의 워크플로우대로 직접 fetch

MCP 도구 우선. MCP가 안 되면 llms.txt / 직접 fetch로 fallback.

MCP 도구

Tool 용도
get_categories() 10개 카테고리 + 카운트 + 요약
list_topics({ category, status, limit }) 필터된 인덱스
get_topic({ slug }) 단일 spec 페이지 풀 마크다운
get_checklist({ category, status }) 체크리스트 형식
search(query, limit) 전문 검색

Prompt: audit_url(url, focus?) — 대상 URL에 대한 감사 플랜 생성.

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.
