What it does

SEO Metadata Audit is an agent skill from simbajigege/book2skills. Audit SEO metadata such as title, description, headings, alt, robots, canonical, schema, viewport, charset, and social tags.

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `README.md`, `quotes/seo-metadata-quotes.md` and `quotes/seo-technical-quotes.md`).

It sits in Marketing & SEO, covering SEO audit. The repository describes itself as: Create best skills based on best books.

When your agent uses it

  • Tasks that involve SEO audit

Example prompts

  • “/seo-metadata-audit”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Identify page purpose and target search intent.
  2. Audit relevance, crawl/index, technical foundations, and structured/social context.
  3. Rank issues by search impact and implementation risk.
  4. Provide corrected tag examples.

What it can do on your machine

Read from SKILL.md and the folder at commit e5ba66c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

SEO Metadata Audit loads about 2.3k tokens when it runs, and up to ~8.9k if it reads all its reference files. Until then it costs about 36 tokens; SKILL.md has 926 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md
