diataxis

diataxis is a skill for Claude Code, Codex from WebMCP-org/npm-packages. It costs 44 tokens per session (1,524 once invoked), scanned A, original, MIT.

A documentation framework that separates content into tutorials, how-to guides, reference material, and explanations. Each type serves a different reader need.

In plain words
What is it for?
It helps classify, write, review, and reorganize technical documentation.
Why use it?
It helps prevent instructional content from mixing unrelated purposes and makes documentation easier to navigate.

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

diataxis 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.

Diataxis Documentation Framework

Complete reference for the Diataxis framework — a systematic approach to technical documentation authoring by Daniele Procida. All content sourced verbatim from diataxis.fr.

When to Use This Skill

This skill should be triggered when:

  • Writing documentation: Creating new docs pages of any type
  • Reviewing documentation: Checking if content is in the right place and follows the right form
  • Restructuring documentation: Reorganizing existing docs into proper Diataxis categories
  • Deciding content type: Determining whether something should be a tutorial, how-to, reference, or explanation
  • Resolving confusion: Distinguishing tutorials from how-to guides, or reference from explanation

The Diataxis Compass

Use this decision table when you need to classify content:

If the content... ...and serves the user's... ...then it belongs in...
informs action acquisition of skill a tutorial
informs action application of skill a how-to guide
informs cognition application of skill reference
informs cognition acquisition of skill explanation

Two questions to ask:

  1. Action or cognition? Is this about doing something or knowing something?
  2. Acquisition or application? Is the user learning or working?

Full compass guidance: references/compass.md

The Four Documentation Types

Tutorials (learning-oriented)

  • An experience guided by a tutor, where the learner acquires skills by doing
  • Teacher holds nearly all responsibility — learner just follows directions
  • Concrete steps, no choices, no branching, ruthlessly minimal explanation
  • Language: "We will...", "First, do X. Now, do Y.", "Notice that...", "You have built..."

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.
