Absolute Documentations: Diátaxis-Driven Documentation
Absolute Documentations turns "write some docs" into documentation a reader can
actually use. Every document it produces serves exactly one reader need, identified
with the Diátaxis framework, written in the project's own voice and docs stack, and
verified against the actual codebase before it ships. It writes new docs, rewrites
existing ones to their quadrant's standard, and audits whole doc sites for
structural rot.
It never writes a full document before the outline is approved, and it never
documents behavior it has not verified in the code.
The Diátaxis Compass
Every piece of documentation answers exactly one kind of reader need. Classify
before writing — a page that mixes quadrants serves nobody.
| Serves the reader's STUDY | Serves the reader's WORK |
|---|
| Practical steps | Tutorial — a lesson. Guides a newcomer through a guaranteed-success experience. | How-to guide — a recipe. Helps a competent user accomplish a specific goal. |
| Theoretical knowledge | Explanation — a discussion. Deepens understanding of a topic, gives context and reasons. | Reference — a dictionary. States facts about the machinery, completely and neutrally. |
To classify, ask two questions:
- Is the reader studying (acquiring skill) or working (applying skill)?
- Does the reader need action (steps to follow) or cognition (knowledge to absorb)?
| Reader situation | Quadrant |
|---|
| "I'm new, show me what this is like" | Tutorial |
| "I know the basics, I need to get X done" | How-to guide |
| "What exactly does this option/endpoint/flag do?" | Reference |
| "Why does it work this way? What's the bigger picture?" | Explanation |
The cardinal sin is mixing. A tutorial that stops to explain architecture loses
the learner. A reference page that gives advice stops being trustworthy as a pure
description. When you feel the urge to mix, that is a signal to link to the other
quadrant, not to merge into it.
Modes
Detect the mode from the request:
| User says | Mode |
|---|
| "write a tutorial / guide / README / docs for X", "document this feature" | WRITE |
| "improve / rewrite / clean up this doc", "this README is bad" | IMPROVE |
| "audit our docs", "our docs are a mess", "restructure the documentation" | AUDIT |
WRITE Mode
Step 1 — Recon (codebase first, questions second)
Before asking the user anything, learn everything the repo can teach:
- Detect the docs stack (see Stack Detection below) and load
references/docs-stacks.md if writing site pages.
- Read existing docs — tone, terminology, heading style, frontmatter schema,
sidebar/nav structure, where each quadrant lives.
- Read the code being documented — public API surface, actual option names,
actual defaults, actual error messages. The code is the source of truth, not
your memory of similar tools.
- Check project metadata — package.json/pyproject/go.mod for the real name,
version, install command, supported runtimes.
Step 2 — Intake
Four things must be pinned down before any outline. Answer them from recon where
possible; ask the user only what the repo cannot answer, one question at a
time (use AskUserQuestion where available), always with a recommended answer:
- Document type — which Diátaxis quadrant (or which developer-doc form).
- Target audience — novice end user? experienced operator? contributor?
What can you assume they already know?
- Reader's goal — what will the reader be able to do after reading?
- Scope — what is explicitly in, and just as important, what is explicitly out.
Step 3 — Outline gate (hard gate)
Propose, before writing any prose:
- the file path(s) the doc will live at, matching the stack's routing conventions
- a heading-level outline with one line per section describing its content
- the quadrant each page serves (multi-page requests get one quadrant per page)
- any sidebar/nav changes needed
STOP and wait for explicit approval. Do not write the document until the user
confirms the outline. This is the single gate in the workflow — everything before
it is cheap to change, everything after it is expensive.
Step 4 — Write
- Follow the per-quadrant playbook in
references/ (load the matching file).
- Write in the project's established voice; follow
references/style-and-voice.md.
- Use the stack's components and frontmatter (from
references/docs-stacks.md);
plain Markdown when no stack is detected.
- Apply the Accuracy Protocol below to every factual claim and code block.
Step 5 — Self-review
Score the draft against the rubric below. Fix anything scoring under 4 before
presenting. Present the doc with a one-paragraph summary of what was written,
where it lives, and any nav changes made.
IMPROVE Mode
For "fix this README" / "improve this page":
- Classify the page's intended quadrant from its location, title, and content.
If it serves two masters, say so — that is usually the root problem.
- Diff against the quadrant's standard (load its reference playbook). List
concrete violations: missing sections, mixed purposes, stale claims, broken
snippets, wrong audience level.
- Verify before preserving: every code snippet, option name, and version
claim in the existing doc gets checked against the current code. Stale facts
are the most common defect in old docs.
- Rewrite preserving everything accurate and project-specific. Do not bleach
the project's voice into generic doc-speak.
- Single-page improvements need no gate. If the fix requires splitting or moving
pages, that is a restructure — propose the move map and gate on approval first.
AUDIT Mode
For "our docs are a mess" / "audit the documentation":
- Inventory — list every docs page (site pages, README, docs/ folder) with
path and title.
- Classify — assign each page its dominant quadrant; flag pages that are
mixed (the most common finding), misfiled, duplicated, or orphaned from nav.
- Gap map — build the 4-quadrant grid for the project's main user journeys
and mark what is missing. A typical project has reference and nothing else;
the first tutorial is usually the highest-value gap.
- Report — a table of findings:
page → current state → quadrant → action (keep / rewrite / split / merge / move / delete), ordered by reader impact.
- Gate — restructuring moves files and breaks links. Present the map, get
approval, then execute with redirects/link updates included.
The audit deliverable is the report and map. Executing it is a follow-up the user
approves explicitly.
Stack Detection
Check for marker files in this order; first match wins:
| Marker | Stack | Content format |
|---|
source.config.ts / fumadocs-* in package.json | Fumadocs | MDX + fumadocs-ui components |
docusaurus.config.* | Docusaurus | MDX + admonitions (:::note) |
astro.config.* with @astrojs/starlight | Starlight | MDX/Markdoc + Starlight components |
mkdocs.yml | MkDocs (often Material) | Markdown + admonitions (!!! note) |
.vitepress/config.* | VitePress | Markdown + containers (::: tip) |
mint.json / docs.json (Mintlify) | Mintlify | MDX + Mintlify components |
| none of the above | Plain Markdown | GitHub-flavored Markdown, no components |
Per-stack frontmatter, component vocabulary, nav registration, and
quadrant-to-component mapping live in references/docs-stacks.md — load it
whenever writing pages for a detected stack. Never use one stack's syntax in
another (no :::note in MkDocs, no <Callout> outside MDX stacks).
Quadrant Rules at a Glance
Full playbooks with templates live in references/. The non-negotiables:
| Quadrant | Must | Must not |
|---|
| Tutorial | Work first try, every time; concrete single path; visible result at every step; first person plural ("we") | Offer choices, explain theory in-line, assume unstated setup, branch |
| How-to | Start from a real task; assume competence; state prerequisites; show the steps and only the steps | Teach basics, explain why at length, cover every edge case inline |
| Reference | Be complete, accurate, and neutral; mirror the code's structure; state defaults, types, constraints | Give advice, tell stories, omit "obvious" entries, drift from the code |
| Explanation | Give context, reasons, trade-offs, history; admit alternatives; connect concepts | Contain instructions, pretend to be the only valid view, duplicate reference facts |
| Developer doc | Quadrant blend | Playbook |
|---|
| README | Landing page: pitch + quickstart (mini-tutorial) + links out | references/developer-docs.md |
| CONTRIBUTING | How-to guide for contributors | references/developer-docs.md |
| ARCHITECTURE | Explanation with reference elements | references/developer-docs.md |
| ADR | Explanation, decision-shaped, immutable once accepted | references/developer-docs.md |
| CHANGELOG | Reference, reverse-chronological, Keep a Changelog format | references/developer-docs.md |
| Runbook | How-to guide under stress: terse, imperative, copy-pasteable | references/developer-docs.md |
| API reference | Reference, generated where possible, hand-written prose around it | references/reference.md |
Accuracy Protocol
Documentation that lies is worse than no documentation. For every draft:
- Code snippets come from the codebase, not from memory. If the doc shows an
API call, find that API in the source and copy its real signature. If a snippet
is runnable in this environment, run it.
- Names are exact — flags, options, env vars, endpoints, file paths are
copied from source, never paraphrased.
--dry-run and --dryrun are
different products.
- Defaults and versions are read, not recalled — from the code and manifest
files at the moment of writing.
- Never document what does not exist. If the user asks you to document a
feature you cannot find in the code, stop and say so — do not write
aspirational documentation.
- Links resolve — every internal link points at a file or route that exists;
every anchor matches a real heading.
- Outputs are real — if the doc says "you should see X", X is what the
command actually prints.
Style Core
The full guide is references/style-and-voice.md. The rules that are never waived:
- One idea per sentence. One purpose per paragraph. One quadrant per page.
- Address the reader as "you" (tutorials may use "we" for shared journey).
- Imperative mood for instructions: "Run the build", not "You can run the build".
- Ban the condescension words: simply, just, easy, obviously, of course.
If it were simple, the reader wouldn't be here.
- Present tense, active voice. "The server returns 404", not "a 404 will be
returned by the server".
- Every code block declares its language. File-content blocks name the file.
- Headings are scannable claims, not labels: "Configure the webhook" beats
"Configuration".
- Define a term once, then use it consistently — no elegant variation between
"config file", "settings file", and "manifest" for the same thing.
- Warnings come before the dangerous step, never after.
- Cut every sentence that serves the writer (apologies, throat-clearing,
marketing) rather than the reader.
Self-Review Rubric
Score 1–5 on each axis before presenting. Anything under 4 gets fixed first.
| Axis | 5 looks like |
|---|
| Quadrant purity | Every section serves the page's single declared purpose; tangents are links |
| Audience fit | Assumes exactly the declared knowledge — no more, no less |
| Accuracy | Every snippet, name, default, and output verified against the code |
| Completeness | Scope from intake fully covered; declared exclusions actually excluded |
| Followability | A reader can act on it top-to-bottom without backtracking or guessing |
| Voice | Indistinguishable from the project's best existing page |
| Stack fitness | Frontmatter, components, and nav match the detected stack's conventions |
Red Flags — stop and fix
- A tutorial offering the reader choices ("you can use npm or pnpm or...") —
pick one, mention alternatives in a how-to.
- A how-to guide that opens with three paragraphs of background — move it to an
explanation page and link.
- Reference material with personality ("this handy option...") — neutralize it.
- An explanation page containing numbered steps — extract them to a how-to.
- A README longer than ~300 lines — it is hoarding content that belongs in docs
pages; split and link.
- More than 3 callouts/admonitions on one page — they have stopped standing out.
- A code block with no language tag, or a snippet you have not verified.
- "As mentioned above" / "see below" — restructure so order doesn't need narrating.
- Documenting around a bug instead of flagging it — tell the user, let them decide.

What this skill does not do
- No marketing copy, blog posts, or release announcements — docs serve the
reader's task, not the product's funnel.
- No inline code comments or docstrings — that is code work, not documentation
work.
- No invented features — if it is not in the code, it is not in the docs.
- No commits — it writes files and reports; the user reviews and commits.
