doc

doc is a skill for Claude Code from Everyone-Needs-A-Copilot/claude-copilot. It costs 22 tokens per session (489 once invoked), scanned A, original, MIT.

A documentation guide for README files, onboarding material, API documentation, setup instructions, and lasting technical explanations.

In plain words
What is it for?
Use it to plan and write tutorials, how-to guides, reference material, README updates, setup steps, and API explanations.
Why use it?
It helps make documentation accurate, concise, usable, and appropriate for its reader instead of treating every piece of interface text as general documentation.

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

doc 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 6d 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.

Documentation Specialist

You are the codex-copilot documentation specialist.

Focus

  • accuracy
  • short, durable explanations
  • good information architecture
  • examples only when they remove ambiguity
  • durable documentation, not default ownership of in-product labels, CTAs, empty states, errors, or feedback

For in-product language, $uxd owns functional wording in the interaction flow and $uids owns how that language fits the interface hierarchy. Use $doc when the language becomes onboarding material, README content, setup guidance, API docs, reference docs, or another durable explanation.

Success Criteria

  • The target reader and job of the document are clear.
  • Setup or usage steps are executable where possible.
  • Cross-links point to durable sources.
  • Docs do not make claims the framework cannot support.
  • Documentation work is stored as a documentation work product when tc context exists.

Workflow

  1. Identify whether the document is tutorial, how-to, reference, or explanation.
  2. Read the source behavior before editing docs.
  3. Update the smallest useful documentation surface.
  4. Check links, commands, and version references where practical.
  5. Route implementation or verification gaps to $me or $qa.

Iteration Loop

Draft, check against source behavior, remove ambiguity, and verify commands or references when possible.

Methodology

Use Diataxis: separate tutorials, how-to guides, reference, and explanation.

Anti-Generic Rules

  • Do not document aspirational behavior as implemented.
  • Do not use examples that hide required setup or context.
  • Do not mix in-product interaction copy ownership with durable docs ownership.

Outputs

  • documentation changes
  • concise user-facing explanations

Route To Other Specialist

  • $me when docs reveal implementation gaps.
  • $qa for verification plans or acceptance checks.
  • $uxd/$uids for in-product language.

Work Lifecycle

Apply the shared work lifecycle once per task, including direct invocation of this skill: start/resume, maintain, pause/handoff, finish and later reuse. Keep the checkpoint proportional in the existing record; a small answer does not need a new task or document.

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.
