documentation

documentation is a skill for Claude Code, Codex from didacrios/ai-coding-protocols. It costs 59 tokens per session (897 once invoked), scanned A, original, MIT.

A documentation skill for writing code comments and system documentation with the Diátaxis framework, a method that separates guides, tutorials, explanations, and reference material.

In plain words
What is it for?
Use it when adding in-code comments or documenting how a system works.
Why use it?
It helps keep technical writing organised and suited to the reader’s needs.

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 21d 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.

High-Precision Documentation Protocol

A protocol for generating in-code comments and system documentation. Uses the Diátaxis framework for external docs and enforces "explain why, not what" for inline comments.

When to Activate

  • Writing or updating in-code documentation (TSDoc, PHPDoc)
  • Creating system documentation in a /docs/ folder
  • Generating READMEs, tutorials, or how-to guides
  • Documenting APIs, schemas, or architectural decisions

Core Concepts

  • Why, not what — documentation explains reasoning, not mechanics
  • Diátaxis framework — four types of docs, each with a clear purpose
  • Synchronized updates — docs update in the same step as the code change
  • Source-verified — read the implementation before writing about it

Detailed Guidance

In-Code Documentation (The "Reference" Layer)

Follow the recursive principle: documentation must explain why, not what.

  • TypeScript: Use TSDoc. Explicitly document generics, complex union types, and interface contracts found in the project.
  • PHP: Use PHPDoc. Mandatory @throws for all identified exceptions in the call chain.
  • Synchronization: Documentation must be updated in the same "Baby Step" as the code change.

System Documentation (The /docs/ Folder)

When generating files for the project's /docs/ directory, strictly apply the Diátaxis Framework:

A. Tutorials (Learning-oriented)
  • Focus: "Learning by doing". Abstract complexity to guarantee a successful first run.
B. How-To Guides (Problem-oriented)
  • Focus: "Solving a specific task". Steps for real-world goals (e.g., "Adding a new Payment Gateway").
C. Explanations (Understanding-oriented)
  • Focus: "Concepts and Architecture". Discuss recursive dependencies, design patterns, and system constraints.
D. Reference (Information-oriented)
  • Focus: "Technical facts". Exhaustive descriptions of APIs, schemas, and classes.

Recursive Context Check

Before writing any documentation:

  1. Source Trace: Read the actual implementation to ensure the documentation is technically accurate.
  2. Global Context: Search the ./docs/ folder for existing guides to avoid duplication and maintain a consistent voice.
  3. Link Verification: Ensure all file paths and cross-references between ./docs/ and source code are valid.

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 didacrios/ai-coding-protocols (2 stars, last pushed 6d ago), licensed MIT. It adds 59 tokens to every session and 897 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.
