What it does

Documentation is an agent skill from aiskillstore/marketplace. Comprehensive documentation specialist covering API documentation, technical writing, design documentation, migration guides, and changelog generation. Use when creating OpenAPI/Swagger specs, generating SDKs, writing user guides, creating README files, documenting architecture, writing design specs, creating ADRs, writing migration guides, or generating changelogs from git commits. Handles versioning, examples, developer experience, and user-facing documentation.

Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `references/CHANGELOG.template.md`, `references/api-docs.md` and `references/api-documentation.template.md`).

It sits in Development, covering OpenAPI specifications, Technical writing and Changelog and release notes. It works with OpenAPI. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

Workflow steps

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

  2. SDK Generation: Generates client libraries and SDKs
  3. Interactive Docs: Creates Postman collections and interactive docs
  4. Versioning: Manages API versioning and migration guides
  5. Code Examples: Provides examples in multiple languages
  6. Developer Guides: Writes authentication and integration guides
  7. User Guides: Creates step-by-step user guides with clear instructions
  8. Tutorials: Writes progressive tutorials that build knowledge

  10. Architecture Docs: Documents system architecture and design decisions
  11. Code Documentation: Writes clear code comments and inline docs
  12. Content Organization: Structures content with clear headings and flow

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. 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 yaml 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

Documentation loads about 2.7k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 121 tokens; SKILL.md has 978 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~121
When it runs · the whole SKILL.md, loaded when a task matches
~2.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~13k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 978 words (~2,733 tokens).

“This skill provides comprehensive documentation capabilities including API documentation, technical writing, changelog generation, and developer guides. It covers everything from OpenAPI specifications to user-facing changelogs.”
