Technical Writer

Expert technical documentation specialist focusing on developer documentation, API references, system architecture docs, runbooks, and knowledge base articles.

Quick Start

1. Identify doc type using Diátaxis: Tutorial, How-to, Explanation, or Reference
2. Know your audience - what they know, what they need to accomplish
3. Start with structure - outline before writing, use templates
4. Include working examples - all code must be tested and runnable
5. Add troubleshooting - anticipate common problems
6. Validate completeness - links work, steps accurate, nothing assumed

Anti-Patterns (10 Critical Mistakes)

1. Wall of Text

Symptom: Dense paragraphs, no headings or visual breaks Fix: Headings, bullet points, tables, code blocks, whitespace

2. Outdated Examples

Symptom: Code samples that don't compile or use deprecated APIs Fix: Test all examples in CI, version-lock dependencies, add "last verified" dates

3. Missing Prerequisites

Symptom: Tutorials assume knowledge/​setup without stating it Fix: List prerequisites upfront, link to setup guides, specify versions

4. Expert Blindness

Symptom: Skipping "obvious" steps that aren't obvious to beginners Fix: Have newcomers test docs, include all steps, explain the "why"

5. No Error Guidance

Symptom: Happy path only, no troubleshooting Fix: Include common errors and solutions, link to support channels

6. Broken Links

Symptom: 404s to moved or deleted pages Fix: Link checking in CI, relative links where possible, redirects for moved content

7. Inconsistent Formatting

Symptom: Different styles, code block languages, heading levels Fix: Style guide, linting (markdownlint), templates for common doc types

8. Missing Context

Symptom: Docs assume reader knows system architecture Fix: Brief context at top, link to architecture docs, explain "where this fits"

9. Stale Screenshots

Symptom: UI screenshots from 3 versions ago Fix: Automate screenshot capture, note UI version, prefer text over images

10. No Versioning

Symptom: Docs don't match user's installed version Fix: Version selector, version badges, maintain docs per major version

Quality Checklist

Structure:

• Follows Diátaxis framework (tutorial/​how-to/​explanation/​reference)
• Appropriate for target audience level
• Consistent formatting and style
• Updated table of contents

Content:

• Code examples are tested and runnable
• All links work (no 404s)
• Version information where relevant
• Includes troubleshooting section

Completeness:

• Prerequisites listed upfront
• All steps included (no expert blindness)
• Error scenarios covered
• Related documentation linked

Validation Script

Run ./​scripts/​validate-docs.sh to check:

• README completeness
• Documentation structure
• ADR format compliance
• Broken links
• Common documentation issues

Documentation Tools
