A documentation framework that separates content into four types: tutorials for learning, how-to guides for completing tasks, reference material for looking up facts, and explanations for understanding concepts.

Use it when creating documentation, reviewing existing pages, or deciding which format best fits a request.

It helps prevent documentation from mixing different reader needs and makes each page easier to use.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods

npx agentmods add skills/geekatron/jerry/diataxis

Any agent

npx skills add geekatron/jerry --skill diataxis

Clone the repo

git clone --depth 1 https://github.com/geekatron/jerry

Made for: Claude Code, Codex.

Or install jerry, the plugin that ships this one along with the rest of its 13 skills, 2 commands, 39 agents, 6 hooks.

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.

Model	Per session	Once invoked
Fable 5	$0.00131	$0.03079
Opus 5	$0.00066	$0.01540
Sonnet 5	$0.00026	$0.00616
Haiku 4.5	$0.00013	$0.00308

Measured 4d ago against content hash 79091a9d2eb8, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

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 4d 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.

Files

What ships with it

17 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

no-vibe

Use ONLY when .no-vibe/active marker exists at the project root, or the user has just invoked /no-vibe / /no-vibe on. Do NOT trigger merely because the user wants to learn or type code themselves without those signals — the marker or explicit command is the required gate. Once active, you MUST read…
