## What it does

The `page` prompt from Microsoft inspects a topic or specific files to produce a structured documentation page. First, it identifies the repository origin using `git remote get-url origin` or asks for confirmation if the project is strictly local. Without resolving the repository context, analysis stops immediately. It then measures project scale by file count and traces execution flow across functions.

The final document follows VitePress frontmatter standards. It combines overview sections, component tables, and at least three dark-theme Mermaid diagrams of two distinct types. Every technical claim and diagram includes precise file and line references. The prompt enforces citing at least five distinct source files across the generated page.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

**Manually: put the files in place**
- File: `.claude/commands/page.md` — Call it with /page. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/page.md` — Call it with /prompts:page. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/page.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/page.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/deep-wiki/commands/page.md

## When to use it
- generate a single wiki page explaining architectural internals from code
- build dark-mode Mermaid flowcharts, state charts, or sequence diagrams
- trace cross-file function calls with exact file and line citations
- extract configuration tables and component lists into VitePress Markdown

## Example prompts
- /page Architecture overview of src/indexer
- Generate a wiki page explaining our authentication flow in auth.ts
- Document the database migration engine with diagrams and source citations

# Deep Wiki: Single Page Generation

Generate a comprehensive wiki page for the specified topic.

## Source Repository Resolution (MUST DO FIRST)

Before generating any page, resolve the source repository context:

1. **Check for git remote**: Run `git remote get-url origin`
2. **Ask the user**: _"Is this a local-only repository, or do you have a source repository URL?"_
   - Remote URL → store as `REPO_URL`, use linked citations: `[file:line](REPO_URL/blob/BRANCH/file#Lline)`
   - Local → use `(file_path:line_number)`
3. **Determine default branch**: Run `git rev-parse --abbrev-ref HEAD`
4. **Do NOT proceed** until resolved

## Inputs

The user will provide a topic/title and optionally specific file paths. Use $ARGUMENTS to determine what to document.

## Depth Requirements (NON-NEGOTIABLE)

1. **TRACE ACTUAL CODE PATHS** — Do not guess from file names. Read the implementation. If function A calls B calls C, follow it all the way.
2. **EVERY CLAIM NEEDS A SOURCE** — File path + function/class name. "X calls Y" must include where.
3. **DISTINGUISH FACT FROM INFERENCE** — If you read the code, say so. If inferring, mark it explicitly.
4. **FIRST PRINCIPLES** — Explain WHY something exists before explaining what it does.
5. **NO HAND-WAVING** — Don't say "this likely handles..." — read the code and state what it ACTUALLY does.

## Mandatory Three-Phase Process

### Phase 1: Strategic Planning (ALWAYS FIRST)

1. Clarify the page's goals, audience, and deliverables
2. Determine scope based on relevant file count:
   - ≤50 files: full coverage
   - 50–300 files: prioritize critical paths
   - >300 files: tiered sampling (entry points, domain models, data access, integration edges)
3. Set documentation budget:
   - Small scope: ~2,000–3,000 words, 3 diagrams (2+ types)
   - Medium scope: ~3,000–5,000 words, 4 diagrams (3+ types)
   - Large/Complex: ~5,000–8,000+ words, 5–8 diagrams (4+ types)

### Phase 2: Deep Code Analysis

1. Read ALL relevant source files completely
2. Identify: architecture patterns, design patterns, algorithms, data flow, state management
3. Map: component dependencies, external integrations, API contracts
4. Record citation anchors: `file_path:line_number` for every claim

### Phase 3: Document Generation

Structure the page with:

- **VitePress frontmatter**: `title` and `description`
- **Overview**: purpose, scope, executive summary — explain WHY this exists
- **At-a-glance summary table**: Key components/concepts with one-line descriptions and source links — readers should grasp the system in 30 seconds
- **Architecture / System Design**: with `graph TB/LR` Mermaid diagram
- **Core Components**: purpose, implementation, design patterns — use a table per component group with "Component", "Responsibility", "Key File", "Source" columns
- **Data Flow / Interactions**: with `sequenceDiagram` (use `autonumber`)
- **State / Lifecycle**: with `stateDiagram-v2` if the system has meaningful state transitions
- **Data Model**: with `erDiagram` if the system has entities or database tables
- **Implementation Details**: key algorithms, error handling, state management
- **Configuration & Deployment**: use tables for config options (Key, Default, Description, Source)
- **References**: inline citations throughout using resolved format
- **Cross-references**: Link to related wiki pages using relative Markdown links (e.g., `[Data Flow](../02-architecture/data-flow.md)`). Whenever a concept, component, or pattern is covered in more depth on another wiki page, link to it inline. Also add a "Related Pages" section at the end listing connected wiki pages.

### Content Organization Rules

- **Progressive disclosure**: Big picture first → drill into specifics. Don't front-load implementation details.
- **Distill, don't dump**: Every paragraph should earn its place. If a section is just listing things, convert it to a table.
