| description | Technical documentation writing and diagram generation. Use when creating docs, syncing documentation with code changes, building Mermaid diagrams, running doc coverage audits, or establishing writing style guides. Use for doc-as-code workflows, ERD generation, sequence diagrams, documentation gap analysis, and AI-assisted drafting. |

Documentation
Technical writing, diagram-as-code, and documentation lifecycle management. Treats docs as code: version-controlled, linted, and CI-verified.
When to use: Creating or updating technical documentation, generating Mermaid diagrams (flowcharts, ERDs, sequence diagrams), auditing documentation coverage against code, or establishing style guides.
When NOT to use: Writing marketing copy, blog posts, or content that does not live alongside code.
Quick Reference
| Task | Approach | Key Point |
|---|
| Doc sync audit | git diff main...HEAD + export scan | Compare symbols against doc coverage |
| Sequence diagram | Mermaid sequenceDiagram + autonumber | Map messages to function calls |
| ERD | Mermaid erDiagram + Crow's Foot | Derive from Drizzle/Prisma schemas |
| Gitgraph | Mermaid gitGraph | Standardize on main/develop/feature branches |
| Feature release doc | Overview + Config + Examples + Troubleshooting | Checklist for every new feature |
| API reference | Generate from JSDoc/TSDoc annotations | Never write API refs manually |
| Style guide | Active voice + present tense + direct address | Conversational but precise |
| AI-assisted drafting | Inventory + gap analysis + draft + human review | AI drafts, humans verify accuracy |
| Markdown standard | YAML frontmatter + language-tagged code blocks | Always specify code block language |
| Complex diagrams | Split into focused sub-diagrams + subgraphs | Limit to 15-20 nodes per diagram |
Common Mistakes
| Mistake | Correct Pattern |
|---|
| Using static images for technical diagrams | Write Mermaid syntax inline in Markdown |
Generic participant names like Agent1 | Use specific service or role names matching the architecture |
| Manually writing API reference docs | Generate from JSDoc/TSDoc annotations in source code |
| Diagrams with 20+ nodes and no grouping | Use subgraphs to group related nodes; limit to 15-20 |
| Documentation referencing outdated defaults | Run doc sync audit comparing exports against coverage |
| Using "Click here" link text | Use descriptive anchor text for accessibility and clarity |
| Skipping heading hierarchy levels | Never go from H2 to H4; keep hierarchy sequential |
| Mixing wall-of-text paragraphs | Use bullet points, tables, and diagrams for scannability |
Delegation
- Scan codebase for undocumented exports and documentation gaps: Use
Explore agent
- Generate a full documentation site with diagrams from an existing codebase: Use
Task agent
- Plan documentation architecture and information hierarchy for a new project: Use
Plan agent
If the mermaid-diagrams skill is available, delegate complex diagram creation and advanced Mermaid syntax questions to it.
Otherwise, recommend: pnpm dlx skills add oakoss/agent-skills -s mermaid-diagrams -a claude-code -y
