Documentation as Code

Overview

P1 Quality & Correctness - Treat documentation with same rigor as source code.

REQUIRED: superpowers:verification-before-completion

Cross-references: automated-standards-enforcement, ci-cd-conformance

When to Use

• Creating/modifying Markdown, ADRs, plans, READMEs
• Adding API documentation, architecture decisions
• PR includes documentation changes

Core Workflow

1. Announce skill and scope
2. Configure validation:
   • markdownlint (Markdown Linting)
   • cSpell (Spell Checking)
   • link-check for broken links
3. Enforce templates (Templates)
4. Add CI validation (fail PR if validation fails)
5. Define review expectations
6. Run all validation before completion

Quick Reference

See Validation Configuration for setup.

Verification Commands for Doc-Only Changes

For documentation-only changes, use these commands to verify quality before completion:

Local Verification

# Markdown formatting check
npm run lint:md

# Spell check
npm run spell

# Both checks (combined command)
npm run validate:docs

Specific File Validation

# Check single file
npx markdownlint-cli2 docs/README.md

# Check documentation directory
npx markdownlint-cli2 "docs/**/*.md"

# Spell check specific files
npx cspell "docs/**/*.md" --no-progress

# Link validation (requires configuration)
npx markdown-link-check docs/README.md

Evidence Capture for Issue Comments

When documenting doc-only verification, post evidence like:

## Verification

- [x] `npm run lint:md` passed
- [x] `npm run spell` passed
- [x] All links verified (no broken references)
- Link validation output: [CI check details](link-to-workflow-run)

Brownfield Baseline Verification

For existing docs without validation:

# Capture baseline violations for documentation
npm run lint:md > lint-baseline.txt 2>&1
npm run spell > spell-baseline.txt 2>&1

# Document findings in baseline file
echo "## Baseline Issues Identified
- Markdown formatting issues: $(wc -l < lint-baseline.txt)
- Spelling issues: $(wc -l < spell-baseline.txt)
" > docs/validation-baseline.md

Key Point: For doc-only changes, verification evidence is process-only (analytical). Link to CI output or command results, not commit SHAs.

Brownfield Approach

1. Run baseline validation
2. Document existing issues
3. Suppress existing violations (Baseline Strategy)
4. Enforce strict validation on new/modified docs only
5. Create incremental cleanup plan

Red Flags - STOP

• "Content matters, not formatting"
• "Can fix typos later"
• "Template is optional"
• "Existing docs aren't validated"

All mean: Apply skill, document exceptions in baseline.
