diataxis

diataxis is a skill for Claude Code, Codex from pproenca/dot-skills. It costs 190 tokens per session (1,845 once invoked), scanned A, original, MIT.

A framework for organizing technical documentation into tutorials, task guides, reference material, and explanations. Each type answers a different reader need.

In plain words
What is it for?
Use it when writing or reviewing READMEs, API documentation, onboarding material, tutorials, or architecture docs.
Why use it?
It prevents documents from mixing incompatible purposes and becoming confusing or difficult to use.

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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (references/queries/scan-docs.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Diátaxis

A runbook for producing and fixing technical documentation with the Diátaxis framework. Diátaxis splits documentation into four modes — tutorials, how-to guides, reference, explanation — because they answer four different user needs that pull in opposite directions. The single idea that makes it work:

Most documentation problems are a single thing: content that tries to serve more than one need at once. Separate the four modes and most confusion dissolves.

Diátaxis is descriptive, not prescriptive — a way to understand documentation, not a template to fill in. Don't wait to understand the whole framework before applying it: pick one small thing, classify it, improve it, publish, repeat.

When to Apply

Use this skill when:

  • Writing or generating new documentation of any kind (README, API docs, guide, onboarding, developer docs) — decide which mode(s) the content needs before writing it.
  • A page is confusing, bloated, or "tries to do everything" — diagnose the type-mixing and split it.
  • Users can't get started, can't complete a task, can't find a fact, or don't understand why — locate the missing or weak mode.
  • Restructuring or auditing an existing doc set — apply the small-step workflow instead of a big rewrite.
  • You're unsure whether something is a tutorial, how-to, reference, or explanation — run the compass.

Do not reach for this skill for pure prose/copy-editing within an already-correct mode (use a copywriting skill), or for design/spec/proposal documents — those are mostly explanation and are better served by dev-rfc or feature-spec.

The four modes

Each mode serves a different user, in a different situation, with a different content style. The quickest way to keep them straight:

Mode Serves Oriented to Analogy Answers
Tutorial a beginner learning learning, study teaching a child to cook "teach me, by doing"
How-to guide a user working a goal, a task a recipe in a cookbook "how do I achieve X?"
Reference a user working information an encyclopaedia entry "what is X exactly?"
Explanation a user studying understanding an article about cooking "why is X this way?"
