documentation

documentation is a skill for Claude Code, Codex from NickPolyder/NP.CoPilot.Config. It costs 44 tokens per session (2,361 once invoked), scanned A, original, MIT.

A workflow for keeping a project's written guides and reference material in its docs/ folder aligned with the code. It covers structure, indexes, links, and explanations of user-visible behavior.

In plain words
What is it for?
Use it when adding, changing, or removing functionality that needs documentation. It helps update guides, indexes, cross-references, and domain-specific details.
Why use it?
It prevents documentation from becoming outdated or hard to find after code changes. It also helps ensure technical details are checked by the right specialist.

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 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.

How it starts

The opening of the file, as written. The whole thing — 326 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Shared policy: Follow instructions/coordination.instructions.md for precedence, invocation, delegation, and handoffs. Apply instructions/workflow.instructions.md for proportional work and verification.

You are helping maintain project documentation in the docs/ folder.

Your goals are to:

  • Update affected documentation when user-visible behavior or operational contracts change.
  • Own docs placement, index maintenance, cross-references, and synchronization with code/user-visible behavior.
  • Follow the established docs structure and the applicable markdown-style instruction instead of redefining style here.
  • Ensure documentation is comprehensive and actionable.
  • Resolve factual uncertainty proportionally; recommend separate deep ADR, test, or security work only when needed.

When to use this skill

Use this skill for a requested substantial documentation task or a workflow's explicit documentation deliverable. Small related edits stay inline. Examples of documentation work include:

  • You add, change, or remove functionality in the codebase.
  • The user asks to document something.
  • You create a new feature, endpoint, page, or entity.
  • Infrastructure or deployment changes are made.
  • An architecture decision is recorded; recommend architecture-decision-record for ADR content and use this skill for placement, index, and sync.
  • A feature plan is finalized (coordinate with the feature-planning skill).
  • UX specifications or wireframes need to be documented.

Do not create a document solely because an internal implementation detail changed.


Agent consultation

Reuse facts already established by the implementation and repository evidence. When separate context is useful, assign unresolved domain questions to investigator, or substantial authorized drafting/restructuring to implementer. Include only relevant skills/domain-guidance.md sections and the document's audience, purpose and write scope. Neither assignment requires the other.

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.

documentation is a skill published in the GitHub repository NickPolyder/NP.CoPilot.Config (2 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 2,361 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
