What it does

Book Metadata SEO is an agent skill from revfactory/harness-100. A specialized skill for the metadata-manager agent covering e-book metadata SEO. Provides BISAC/KDC classification, keyword optimization, bookstore-specific description strategies, pricing psychology, and platform-specific distribution settings. Use for 'metadata,' 'book classification,' 'keywords,' 'e-book distribution,' and similar topics.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is Apache-2.0.

When your agent uses it

  • Book classification
  • E-book distribution

Example prompts

  • “metadata,”
  • “book classification,”
  • “keywords,”
  • “/book-metadata-seo”

Workflow steps

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

  1. Seed Keywords: 3-5 core topics of the book
  2. Expanded Keywords: Related terms derived from seeds
  3. Competitive Analysis: Check keywords of similar books
  4. Long-tail: Longer keywords reflecting specific search intent

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. 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 html).

    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

Book Metadata SEO loads about 1.5k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 488 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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

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.

Book Metadata SEO — E-Book Metadata SEO Methodology
