diataxis-classify

diataxis-classify is a skill for Claude Code, Codex from reem-sab/tech-writer-prompts. It costs 125 tokens per session (870 once invoked), scanned A, original, MIT.

A tool for classifying documentation pages using Diátaxis, a framework that separates tutorials, task guides, reference material, and explanations. It also identifies passages that mix these purposes.

In plain words
What is it for?
Use it to identify a page's main documentation type, flag mismatched sections, and propose splitting the content into focused pages.
Why use it?
It helps reveal when a page is trying to teach, instruct, define, and explain at the same time, making it harder 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-classify 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 10d 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.

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Diataxis Classify

Classifies a page against the four Diataxis modes, which are tutorial, how-to guide, reference, and explanation. It identifies passages that belong to a different mode than the primary one of the page, and proposes a concrete split when the mixing is bad enough to matter.

Inputs

  • {{PAGE}}: The documentation page to classify.

How to apply

Substitute each {{PLACEHOLDER}} above with the user's actual content, then follow the prompt below exactly — including its output format and its stated limits.


You are classifying a documentation page against the Diataxis framework's four modes:

  • Tutorial — learning-oriented. A guided lesson for a beginner, taking them through a complete experience step by step. Success is "the reader learned something by doing it," not "the reader accomplished a specific real task."
  • How-to guide — task-oriented. Steps to accomplish a specific goal, written for someone who already has the basics and wants to get something done. Assumes competence; skips explaining why.
  • Reference — information-oriented. Dry, structured, complete description of the system (parameters, options, behavior) — describes, doesn't guide or persuade.
  • Explanation — understanding-oriented. Discussion of concepts, design decisions, and the "why" behind the system. Doesn't tell the reader to do anything.

Method

  1. Determine the page's primary mode from its overall structure and intent — what is it actually trying to help the reader do?
  2. Scan for passages that belong to a different mode than the primary one. A passage counts as "mixed in" only if it would genuinely serve the reader better on a separate page written for that mode — not every aside or one-sentence rationale is a violation. A how-to guide with one sentence of "why" for a non-obvious step is fine; three paragraphs of conceptual explanation embedded in the middle of numbered steps is not.
  3. For each mixed-in passage, name which mode it actually belongs to and quote it.

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.
