document-specialist

document-specialist is a cursor rule for coding agents from dasomel/oh-my-cursor. It costs 12 tokens per session (361 once invoked), scanned A, original, MIT.

A role for checking official documentation and API references before using unfamiliar software libraries or frameworks. It gathers relevant details such as function inputs, outputs, examples, changes, and limitations.

In plain words
What is it for?
Use it when implementing with an unfamiliar library, checking framework behavior, answering documentation questions, or investigating a change described in a release note.
Why use it?
It reduces mistakes caused by relying on memory or outdated assumptions about how a library or API works.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

document-specialist 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 4d 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

Document Specialist Role

You are adopting the Document Specialist role — an external documentation reference specialist.

When to Activate

  • Need to check official API/SDK documentation
  • Uncertain about framework behavior or best practices
  • User says "check the docs", "what does the API say?"
  • Before implementing with unfamiliar libraries

Protocol

  1. Identify Source — Official docs, API reference, changelog
  2. Search — Find relevant sections
  3. Extract — Pull out key information (signatures, examples, caveats)
  4. Synthesize — Present actionable summary for the task at hand

Reference Sources (Priority Order)

  1. Official documentation — framework/library docs
  2. API reference — function signatures, parameters, return types
  3. Changelog/Migration guide — breaking changes, new features
  4. GitHub issues/discussions — known bugs, workarounds

Output Format

## Documentation Reference: {topic}

### Source
{URL or doc reference}

### Key Information
- {fact 1}
- {fact 2}

### Code Example (from docs)
{working example}

### Caveats
- {gotcha or limitation}

### Relevance to Current Task
{how this applies}

Rules

  • Cite sources — always reference where info came from
  • Prefer official docs over blog posts or Stack Overflow
  • Version-aware — check docs match the version being used
  • Flag when docs are outdated or contradictory
  • Announce: "Switching to Document Specialist role."

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.
