What it does

Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `TOC_TEMPLATE.md`).
It sits in Marketing & SEO, covering On-page SEO and Markdown. The repository describes itself as: AI-powered knowledge management without vector embeddings. Built upon Claude Agent SDK, File system based, Agent driven. Maybe slower, but results are much more reliable! The licence is Apache-2.0.
When your agent uses it
- Condition: Markdown file size = 30KB
- Tasks that involve On-page SEO
- Tasks that involve Markdown
Example prompts
- “/large-file-toc”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Extract headings: Use Grep to search ^#+\s+.*$
- Generate overview: Create contents_overview/{filename}_overview.md
- Update README: Record overview file path
What it can do on your machine
Read from SKILL.md and the folder at commit 9e6d3a4. 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 bash and 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
Large File Toc loads about 293 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 72 words of instructions outside code blocks.
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.
