Technical Documentation

Execution-ready patterns for clear, maintainable technical documentation.

Modern best practices (January 2026): docs-as-code, ownership + review cadence, documentation QA gates (links/style/spelling), AI-assisted drafting + review, OpenAPI 3.2.0 where streaming schemas matter, and GEO (Generative Engine Optimization) for AI search.

Quick Reference

Documentation Type	Template	When to Use
Project README	readme-template.md	New project, onboarding
Architecture Decision	adr-template.md	Technical decisions
API Reference	api-docs-template.md	REST/GraphQL APIs
Changelog	changelog-template.md	Version history
Contributing Guide	contributing-template.md	Open source, teams

Workflow

Identify the documentation type and audience.
Find existing patterns in the repo; follow local conventions.
Start from the closest template in
```
assets/
```
and adapt.
Add ownership + review cadence for critical docs (runbooks, onboarding, API reference).
Run documentation QA (links, formatting, spelling, examples) before merging.

Decision Tree

text

User needs: [Documentation Task]
    ├─ New project? → **README.md**
    ├─ Technical decision? → **ADR**
    ├─ Building API? → **OpenAPI spec** + api-docs-template
    ├─ New version? → **CHANGELOG.md**
    ├─ Team collaboration? → **CONTRIBUTING.md**
    ├─ Documenting code? → **Docstrings** (JSDoc, Python)
    └─ Building docs site? → **MkDocs** (Python) or **Docusaurus** (JS)

Cross-Platform AI Documentation

AGENTS.md Standard

Prefer

AGENTS.md

as the cross-tool source of truth. If a specific tool requires a different filename (example: Claude Code uses

CLAUDE.md

), keep it aligned via a symlink only when you want identical content across tools.

bash

# If `CLAUDE.md` does not exist and you want identical content:
ln -s AGENTS.md CLAUDE.md

Do / Avoid

Do

Assign owners and review cadences to critical docs
Add CI checks for links, style, and staleness
Prefer small, task-oriented docs over big wiki pages
Use Keep a Changelog format with semantic versioning

Avoid

Docs without owners (guaranteed to rot)
Stale runbooks (dangerous during incidents)
Copy/paste docs that drift from code
