Write and maintain technical documentation. An agent skill from rasengan-dev/rasenganjs.

  • Works in 5 steps: Write for the reader — Who is reading… → Start with the most useful information —… → Show, don't tell — Code examples,… → …
  • With write docs for
  • SKILL.md covers Document Types and Principles
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Documentation is an agent skill from rasengan-dev/rasenganjs. Write and maintain technical documentation. Trigger with "write docs for", "document this", "create a README", "write a runbook", "onboarding guide", or when the user needs help with any form of technical writing — API docs, architecture docs, or operational runbooks.

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Technical documentation and Runbooks and postmortems. The repository describes itself as: Rasengan.js is a full-stack meta-framework for React — SSR, SSG, and a built-in backend, running anywhere from Node.js to the edge, without compromising on performance. The licence is MIT.

When your agent uses it

  • With write docs for
  • Create a README
  • Write a runbook
  • Onboarding guide

Example prompts

  • “write docs for”
  • “document this”
  • “create a README”
  • “/documentation”

Workflow steps

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

  1. Write for the reader — Who is reading this and what do they need?
  2. Start with the most useful information — Don't bury the lede
  3. Show, don't tell — Code examples, commands, screenshots
  4. Keep it current — Outdated docs are worse than no docs
  5. Link, don't duplicate — Reference other docs instead of copying

What it can do on your machine

Read from SKILL.md and the folder at commit 3fb89eb. 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.

    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 375 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 159 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~375

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.
