name: technical-writing description: Write clear technical prose. Multi-layer review ensures structure, clarity, and evidence quality.

Technical Writing

Write clear technical prose with rigorous quality review.

When to Use

• Writing technical documentation, design docs, or READMEs
• Drafting blog posts or technical reports
• Writing research papers or whitepapers
• Any technical writing that needs to transfer ideas clearly
• Existing draft needs systematic improvement

Don't use for: Quick notes, informal messages, or throwaway text.

Core Principles

Every sentence serves one goal: transfer ideas from author to reader.

1. Give away the punchline - State your point upfront, don't bury it
2. Topic sentences - First sentence of each paragraph enables scanning
3. Active voice - "The system handles X" not "X is handled by the system"
4. Consistent terminology - Same concept uses same term throughout
5. Concrete before abstract - Examples before generalizations
6. Figure-first explanations - Lead with diagrams, standalone captions

Quality Rubric

Review occurs in three sequential layers. Each layer has specific focus.

Layer 1: Structure

Criterion	Requirement
Main point upfront	Reader knows the point within first paragraph
Logical flow	Each section follows naturally from the previous
Section balance	No section dominates inappropriately
Scannable	Headers and topic sentences tell the story
Completeness	No obvious gaps in the argument or explanation

Layer 2: Clarity

Criterion	Requirement
Active voice	No passive constructions obscuring agency
Topic sentences	First sentence of each paragraph states main point
Consistent terminology	Same concept uses same term throughout
No weasel words	Avoid "clearly," "obviously," "simply," "just"
Paragraph coherence	3-5 sentences, single idea, transition words
Concrete examples	Abstract claims grounded in specifics

Layer 3: Evidence

Criterion	Requirement
Claims supported	Every claim has evidence or reasoning
Examples work	Code samples run, commands execute
Figures standalone	Captions explain without requiring text
Links valid	External references resolve
Accuracy	Technical details correct and verifiable

Document Types

The same principles apply across formats, with emphasis shifts:

Type	Emphasis	Structure
Documentation/README	Scannable, working examples	What → Why → How → Reference
Blog/Article	Hook, narrative, examples	Hook → Problem → Solution → Implications
Design Doc	Context, alternatives, tradeoffs	Context → Goals → Design → Alternatives → Plan
Research Paper	Contribution clarity, evidence rigor	Problem → Contribution → Approach → Evaluation
Technical Report	Completeness, actionable conclusions	Summary → Findings → Analysis → Recommendations

Inputs

Before drafting:

• Topic and scope
• Target audience (who is reading this?)
• Key points to convey
• Supporting material (code, diagrams, data)

Output Schema

{
  "topic": "string",
  "audience": "string",
  "status": "DRAFT | REVIEWED | COMPLETE",
  "sections": [
    {
      "heading": "string",
      "content": "string"
    }
  ],
  "review_history": {
    "structure": "PASS | REVISE",
    "clarity": "PASS | REVISE",
    "evidence": "PASS | REVISE"
  }
}
