What it does
Document Code is an agent skill from codeaholicguy/ai-devkit. AI DevKit · Document a code entry point with structured analysis, dependency mapping, and saved knowledge docs. Use when users ask to document, understand, or map code for a module, file, folder, function, or API.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Frontend & Design. The repository describes itself as: The control plane for AI coding agents. The licence is Apache-2.0.
When your agent uses it
- Users ask to document
- Map code for a module
Example prompts
- “/document-code”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 90dcca0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
cdn.jsdelivr.net
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Document Code loads about 1k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 487 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
- 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>"
- Collect Source Context
- Summarize purpose, exports, key patterns.
- Folders: list structure, highlight key modules.
- Functions/APIs: capture signature, parameters, return values, error handling.
- 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.
- Synthesize
- Overview (purpose, language, high-level behavior).
- Core logic, execution flow, patterns.
- Error handling, performance, security considerations.
- Improvements or risks discovered during analysis.
- Create Documentation
- Normalize name to kebab-case (
calculateTotalPrice→calculate-total-price). - Create
docs/ai/implementation/knowledge-{name}.mdusing the Output Template — this is the source of truth. - Include mermaid diagrams when they clarify flows or relationships.
- 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}.htmlper 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.
Show full SKILL.md (256 more words)Show less
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
| Rationalization | Why It's Wrong | Do Instead |
|---|---|---|
| "I already understand this code" | Understanding ≠ documented understanding | Write it down, then verify |
| "The code is self-documenting" | Future readers lack your current context | Capture the why, not just the what |
| "Dependencies are obvious" | Implicit dependencies cause surprises | Map them explicitly to depth 3 |
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.

When should I use Document Code?
Document Code fits situations like: users ask to document; map code for a module.
How do I install Document Code in Claude Code?
Run `npx skills add codeaholicguy/ai-devkit --skill document-code -a claude-code`. Or copy the skill folder (skills/document-code in codeaholicguy/ai-devkit) into .claude/skills/document-code in your project. Claude Code loads it when a task matches its description.
How do I install Document Code in Codex?
Run `npx skills add codeaholicguy/ai-devkit --skill document-code -a codex`. Or copy the skill folder (skills/document-code in codeaholicguy/ai-devkit) into .agents/skills/document-code in your project. Codex loads it when a task matches its description.
Can I use Document Code in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add codeaholicguy/ai-devkit --skill document-code -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/document-code, .gemini/skills/document-code, .github/skills/document-code and .opencode/skills/document-code in your project.
What does Document Code need to run?
Going by SKILL.md and its folder, Document Code needs the command-line tools its instructions call (npx). Our summary lists: Node.js.
Does Document Code access the network?
SKILL.md names 1 domain. In commands or code: cdn.jsdelivr.net; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Is Document Code safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Document Code use?
Document Code is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Document Code use?
About 1k tokens (SKILL.md is roughly 4.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Document Code?
Skills that share tags, products or a category with Document Code: Web Artifacts Builder (anthropics/skills, 180k stars), React Doctor (makeplane/plane, 61k stars), Impeccable (bestofjs/bestofjs, 3.1k stars) and Figma Design System Builder (warpdotdev/warp, 65k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
