Code Documentation Assistant

Build structured understanding of code entry points with an analysis-first workflow.

Hard Rule

• Do not create documentation until the entry point is validated and analysis is complete.

Workflow

1. Gather & Validate

• Confirm entry point (file, folder, function, API), purpose, and desired depth.
• Verify it exists; resolve ambiguity or suggest alternatives if not found.
• Search for existing knowledge before analyzing: npx ai-devkit@latest memory search --query "<entry point name or purpose>"

2. Collect Source Context

• Summarize purpose, exports, key patterns.
• Folders: list structure, highlight key modules.
• Functions/APIs: capture signature, parameters, return values, error handling.

3. Analyze Dependencies

• Build dependency view up to depth 3, track visited nodes to avoid loops.
• Categorize: imports, function calls, services, external packages.
• Exclude external systems or generated code.

4. Synthesize

• Overview (purpose, language, high-level behavior).
• Core logic, execution flow, patterns.
• Error handling, performance, security considerations.
• Improvements or risks discovered during analysis.

5. Create Documentation

• Normalize name to kebab-case (calculateTotalPrice → calculate-total-price).
• Create docs/ai/implementation/knowledge-{name}.md using the Output Template — this is the source of truth.
• Include mermaid diagrams when they clarify flows or relationships.

6. Offer HTML Artifact

• After the markdown is written, ask the user once: "Also generate an HTML artifact for easier scanning? (y/N)".
• If yes, generate sibling docs/ai/implementation/knowledge-{name}.html per the HTML Artifact spec. Regenerate from the markdown on subsequent runs; never hand-edit.
• If no or no response, stop here — markdown alone is a complete result.

HTML Artifact

Generated only when the user opts in at step 6. A self-contained HTML file optimized for scanning, not reference reading. Complements the markdown — does not replace it.

Constraints:

• Single file. Inline CSS. No build step. Only external asset allowed is mermaid via CDN (https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js).
• Card-based grid layout, not a long scroll. The reader should capture structure at a glance.
• Responsive down to laptop width. Print-friendly.
• No interactivity beyond collapsible deep-dives and mermaid pan/zoom.

Section mapping (from the Output Template):

• Overview → hero card: title, one-line purpose, language/type badges.
• Implementation Details → grid of sectioned cards with short bullets, not prose.
• Dependencies → graph card (mermaid) plus a categorized list (imports, calls, services, external).
• Visual Diagrams → full-width rendered mermaid blocks.
• Additional Insights → callout boxes, color-coded by kind (info, warning, risk).
• Next Steps → checklist card.
• Metadata → compact footer (date, depth, files touched).

Red Flags and Rationalizations

Validation

• Documentation covers all Output Template sections.
• If an HTML artifact was generated, it opens standalone in a browser, renders mermaid, and reflects the markdown content (no drift).
• Summarize key insights, open questions, and related areas for deeper dives.
• Confirm file path(s) and remind to commit.
