Diátaxis Documentation Creator

Create new documentation in the correct Diátaxis quadrant using structured templates.

        +----------------+------------------+
Study   |   TUTORIALS    |   EXPLANATION    |
        |   (learning)   | (understanding)  |
        +----------------+------------------+
Work    |   HOW-TO       |   REFERENCE      |

When to Use

• Writing documentation from scratch for a new project or feature
• User requests a specific type of documentation
• Filling gaps identified by a diataxis-audit
• Adding a new document to an existing documentation set

Required Inputs

1. Topic: What the documentation is about
2. Quadrant (optional): If the user specifies tutorial/how-to/reference/explanation. If not specified, classify the request:
   • "Show me how to get started" → Tutorial
   • "How do I configure X?" → How-to guide
   • "What are all the options for Y?" → Reference
   • "Why does Z work this way?" → Explanation
3. Target audience (optional): Experience level and context
4. Output path (optional): Where to write the document

Recommended Creation Order

When building documentation from scratch for a project, follow this order:

1. Tutorial — fastest value for new users, validates the system works, reveals UX issues
2. Reference — most straightforward to generate, essential for all projects, partially automatable
3. How-to guides — based on real user questions, grows organically from support and issues
4. Explanation — requires mature understanding, benefits from real-world experience

Workflow

Phase 1: Classify the Request

Determine which quadrant the requested documentation belongs to. If ambiguous, ask the user.

Phase 2: Gather Context

• Read relevant source code, existing docs, or specs
• Identify the target audience's expected knowledge level
• Note related documents in other quadrants for cross-linking

Phase 3: Write Using the Appropriate Template

Apply the template for the selected quadrant (see below). Follow the quadrant's rules strictly:

Tutorial rules:

• Use imperative mood ("Create a file", not "You should create a file")
• Every step must be concrete and testable
• Show expected output after each step
• Don't explain concepts — link to explanation docs instead
• Build to a complete, meaningful result
• Keep the learner on a safe, reliable path — no choices

How-to guide rules:

• State the goal in the title ("How to [verb] [noun]")
• Assume the reader is competent — don't teach basics
• Offer alternatives where they exist
• Focus on the practical outcome
• Include verification steps

Reference rules:

• Be factual, complete, and consistent
• Use structured formats (tables, parameter lists, type signatures)
• No narrative — information only
• Mirror the structure of the thing being documented
• Include minimal examples for illustration, not instruction

Explanation rules:

• Frame the topic with context and motivation
• Discuss alternatives and trade-offs honestly
• Connect to the "why" — design decisions, history, constraints
• Use a discursive, exploratory tone
• Don't include procedural steps

Phase 4: Cross-link

Add links to related documents in other quadrants:

• Tutorial → how-tos (next steps), reference (details), explanation (concepts)
• How-to → tutorials (if background needed), reference (details), explanation (rationale)
• Reference → tutorials (introduction), how-tos (usage examples)
• Explanation → tutorials (hands-on), how-tos (practical application)
