Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.01969 |
| Opus 5 | $0.00016 | $0.00984 |
| Sonnet 5 | $0.00007 | $0.00394 |
| Haiku 4.5 | $0.00003 | $0.00197 |
Grade A, and why
seo-metadata-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 12d 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.

SEO Metadata Audit Skill
Knowledge source: 影响SEO最重要的10个metadata by 哥飞.
Overview
Use this skill to audit a webpage's most important SEO metadata and produce a prioritized repair plan. It supports SEO practitioners, developers, founders, and content teams who need to diagnose whether a page gives search engines clear, crawlable, canonical, mobile-friendly, and structured signals.
When to Use This Skill
Use this skill when the user provides a URL, HTML, page spec, or metadata list and asks:
- "Audit this page's SEO metadata."
- "Are my title and description good?"
- "Do I need canonical, robots, schema, or Open Graph tags?"
- "Why is this page not ranking or showing correctly?"
- "Create metadata for this page."
Core Principle
SEO metadata works as a system: each tag clarifies what the page is about, how search engines should process it, and how users see it in search or social contexts. Do not optimize one tag while breaking crawlability, canonicalization, mobile rendering, or semantic structure.
Workflow Inventory
| Workflow | User question pattern | Inputs | Steps | Output | Independent trigger? | Distinct references? | Triage score | Should be subskill? | Reason |
|---|---|---|---|---|---|---|---|---|---|
| Full metadata audit | "Audit this page" | URL/HTML, target keyword, page purpose | Inspect all tag families; rank issues | Priority issue table | Yes | Yes | 3 | No | Primary workflow; all tags interact. |
| Snippet optimization | "Fix title/description" | Title, description, keyword, intent | Check length, uniqueness, click value | Rewrite variants | Yes | Yes | 3 | No | Narrow but uses same metadata scoring. |
| Crawl/index control | "Should this page be indexed?" | Page role, duplicates, robots/canonical | Decide index, follow, canonical | Indexing directive plan | Yes | Yes | 3 | No | Kept single-file because output rolls into audit plan. |
| Structured/social preview | "Add schema/Open Graph" | Page type, entity data, social preview | Choose schema and OG/Twitter tags | Markup checklist | Yes | Yes | 3 | No | Same input and repair report. |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

seo-metadata-audit is a skill published in the GitHub repository simbajigege/book2skills (163 stars, last pushed 17d ago), licensed MIT. It adds 33 tokens to every session and 1,969 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
