CodeWiki Generator

Generate a deep, code-first project wiki and VitePress documentation site (DeepWiki-style) for a repository. Use when asked to create a complete wiki/manual for a new codebase, build a code-first documentation site, or generate a codewiki/ folder with structured Markdown, diagrams, and navigation based on the source code (not existing docs).

Overview

Generate a DeepWiki-style, code-first documentation site for a given repository. The output will reside in the codewiki/ directory, including a VitePress configuration and an auto-generated sidebar. The documentation must reflect the project's current state and prioritize explaining the system's design rationale over merely describing its functionality.

Workflow

0) Confirm Language Preference

Ask the user: "What language should the documentation be written in? (e.g., English, 中文, 日本語, etc.)" IF the user specifies a language THEN store the provided language and apply it to all generated prose content. ELSE IF the user does not specify a language THEN default to English.

1) Inspect the Codebase First (Code > Docs)

• Scan source files, configuration files, build/test pipelines, entry points, and architectural directories.
• Treat existing documentation (e.g., README, docs/) as secondary hints.
• Prioritize code evidence as the ultimate source of truth.
• Identify and report any discrepancies between documentation and code.

2) Analyze Codebase → Structured Metadata

Execute the analyzer script to scan the codebase and generate structured metadata. <skill-root> refers to the directory containing this SKILL.md.

bash

python3 <skill-root>/scripts/codewiki_analyze.py \
  --repo-root <repo-root> \
  --out-dir codewiki \
  --force

This command generates the following outputs:

• codewiki/.meta/ directory containing deps.json, entrypoints.json, evidence.json, doc_plan.json, and symbols.json (if ctags is available).
• codewiki/quality-report.md detailing coverage and pages with low confidence.
• VitePress configuration scaffolding, without placeholder .md files.

Note: This step does not generate placeholder .md files. The LLM is responsible for writing documentation content directly in Step 4. Note: Images referenced in existing Markdown files are copied into codewiki/assets/.

3) Dynamically Determine the Documentation Set

• Include all minimally required pages.
• Add conditional modules only when corresponding code evidence exists.
• Split or merge pages based on project size and complexity.
• Adhere to the guidelines specified in references/structure-and-heuristics.md.
• Use lowercase directory and file names for all generated documentation.

4) Write the Documentation (Code-first, Visual-first)

Read codewiki/.meta/doc_plan.json and process each planned page:

• IF a page has no supporting evidence OR low relevance to the codebase THEN skip that page.
• ELSE create an .md file only for pages containing actual content.

Writing guidelines:

• Use the language determined in Step 0 for all prose content.
• Retain original formatting for code snippets, file paths, and technical terms.
• Start every page with a low-contrast # Related Code block (fenced text block), not a heading.
• Utilize Mermaid for diagrams (context, class, sequence, component, dataflow).
• Adhere to Mermaid-safe syntax: use simple node IDs, avoid /, (), and : in labels, and prefer node[plain label].
• Explain the rationale behind design choices, trade-offs, and constraints.
• Provide informed opinions: highlight strengths, technical debt, or "code smells."
• Link concepts to specific file paths, classes, or entry points.
• Reuse existing images/diagrams IF they are accurate.
• Maintain Markdown lint-friendly practices: consistent headings, no trailing spaces, and proper list formatting.

Refer to references/doc-templates.md for detailed, evidence-linked page templates.

5) Refresh Sidebar and Run the Site

After documentation generation, update the sidebar to reflect the actual files:

bash

python3 <skill-root>/scripts/codewiki_bootstrap.py \
  --repo-root <repo-root> \
  --out-dir codewiki \
  --refresh-sidebar

Install documentation dependencies (Mermaid support is enabled by default):

bash

npm --prefix codewiki install

Launch the documentation site:

bash

npm --prefix codewiki run docs:dev

Alternative launch command (without prior npm install):

bash

npx -p vitepress -p vitepress-plugin-mermaid -p mermaid vitepress dev codewiki

6) Offer Optional Workflows

After the site is operational, inform the user about available options:

"Documentation site is ready! You can now:

• Option A: Deploy to Cloudflare Pages — publish the site to a live URL
• Option B: Add multi-language support (i18n) — translate docs to another language

Let me know if you'd like to proceed with any of these."

Optional Workflows

These workflows are available for execution after the core documentation generation process is complete.

Option A) Deploy to Cloudflare Pages

Deploy the documentation site to Cloudflare Pages using the wrangler CLI.

Trigger: The user requests to deploy, publish, or host the documentation.

See: references/deploy-cloudflare.md for comprehensive instructions (including wrangler installation, login verification, build process, deployment, and updating index.md with the live URL).

Option B) Add Multi-language Support (i18n)

Translate existing documentation into a second language and configure the VitePress language switcher.

Trigger: The user requests translation, multi-language, or internationalization (i18n) support.

See: references/i18n-setup.md for comprehensive instructions (including directory structure, VitePress locales configuration, and translation guidelines).

Quality Bar (Non-negotiable)

• Visual First: Prioritize diagrams over extensive text blocks.
• Insightful: Explain design intent beyond mere mechanics.
• Opinionated: Highlight architectural strengths and identified risks.
• Linked: Reference concrete files/classes for all key concepts.
• Code-first: The codebase is the authoritative source; documentation serves as a complementary explanation.
