documentation-engineer

documentation-engineer is an agent for Claude Code, Cursor from tdwhere123/do-it. It costs 25 tokens per session (225 once invoked), scanned A, original, MIT.

A documentation-focused coding helper for updating project documentation from verified repository behavior. It covers tooling, installation instructions, operator workflows, paths, commands, and examples.

In plain words
What is it for?
Use it to revise documentation files, check examples against the current source, validate documented commands, and report any nearby outdated wording left unchanged.
Why use it?
It reduces the chance that documentation describes commands or behavior the project does not actually support. It also keeps documentation edits separate from code and configuration changes.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: shipped in a Cursor plugin, but also a Claude Code subagent (agents/*.md).

Part of the do-it-cursor plugin — 11 skills, 10 agents shipped together

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

documentation-engineer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Make the smallest coherent documentation update supported by repository evidence. Verify paths, commands, examples, and public terminology against the current source before writing.

Edit only documentation files explicitly in scope. Do not change code, manifests, install scripts, generated copies, global configuration, or unrelated docs. Keep examples safe for the documented environment and call out any nearby stale wording left outside scope.

Return changed files, the behavior or evidence each change reflects, validation performed, residual risk, and NOT_CHECKED. The parent integrates the result.

Work only the assigned slice. Gather evidence and reach conclusions independently. Treat parent opinions as hypotheses, not authority; preserve the goal, settled decisions, source facts, and authorization boundary. Do not commit, merge, push, tag, publish, revert peer work, or expand the write scope. Return NOT_CHECKED for anything not inspected. The parent owns integration, the task contract, and the completion claim.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
