Analysis Execution Flow

Step 1: Collect Repository Metadata

Use the following tools to gather information (execute in parallel):

1. Directory Structure - Use Glob to scan **/* for the complete file tree
2. Package Management - Read package.json, go.mod, Cargo.toml, pyproject.toml, pom.xml, etc.
3. Configuration Files - Read tsconfig.json, .eslintrc.*, vite.config.*, webpack.config.*, etc.
4. CI/CD - Read .github/workflows/*, .gitlab-ci.yml, Dockerfile, etc.
5. Git History - Get file change frequency from the last 100 commits

Step 2: Identify Core Systems

Determine core systems based on the following signals:

Step 3: Deep Analysis of Each System

For each core system, perform:

1. Read all files in that directory
2. Identify main class, function, and type definitions
3. Trace import/export dependency chains
4. Identify design patterns (Repository, Factory, Observer, etc.)
5. Extract key configurations and constants

Step 4: Generate Mermaid Diagrams

Based on the analysis results, generate:

• At least 1 architecture overview diagram
• At least 1 module dependency diagram
• At least 1 core workflow sequence diagram
• Add state diagrams and data flow diagrams as needed

Step 5: Assemble Report

Assemble the complete report according to the structure specification above, output to REPOWIKI.md.

Source File Reference Specification

Each section must include collapsible source file references:

<details>
<summary>Related Source Files</summary>

- `src/core/engine.ts` - Core engine implementation
- `src/core/types.ts` - Type definitions
- `src/config/default.ts` - Default configuration
</details>

Reference rules:

• Only reference files directly related to the current section
• Each reference includes a brief description
• Sort by importance, most critical files first
• 3-10 referenced files per section

Table Usage Specification

Tables must be used in the following scenarios:

1. Tech Stack - Inventory of languages, frameworks, and tools
2. Module Inventory - Paths, responsibilities, and dependencies of all modules
3. Configuration Comparison - Configuration differences across environments/modes
4. API Inventory - Methods, parameters, and return values of public APIs
5. Dependency Inventory - Versions and purposes of key dependencies

Output Requirements

1. Filename: REPOWIKI.md, placed in the repository root
2. Language: Match the user's conversation language (Chinese conversation = Chinese report)
3. Length:
   • Small projects (<50 files): 800-1500 lines
   • Medium projects (50-200 files): 1500-3000 lines
   • Large projects (>200 files): 3000-6000 lines
4. Diagram count: At least 3 Mermaid diagrams, 6-10 for large projects
5. Table count: At least 3 tables
6. Code blocks: Key configurations and interface definitions, no more than 30 lines each

• Contains project overview and one-line positioning
• Tech stack table is complete and accurate
• Repository structure Mermaid diagram matches reality
• Each core system has an independent section
• Each section has collapsible source file references
• Module dependency diagram correctly reflects actual dependencies
• At least one sequence diagram shows core workflows

MyApp is an e-commerce SaaS platform for small and medium-sized merchants. It provides
product management, order processing, payment integration, and real-time inventory
synchronization as core features. The project uses Next.js App Router architecture,
Prisma as the ORM, and PostgreSQL as the primary database.

    [*] --> Created: User places order
    Created --> Paying: Initiate payment
    Paying --> Paid: Payment successful
    Paying --> Cancelled: Payment timeout/failure
    Paid --> Shipping: Merchant ships

| Rust | Cargo.toml, crate structure, trait definitions |
| Java/Kotlin | pom.xml/build.gradle, package structure, class hierarchy |
| Monorepo | workspace config, inter-package dependencies, build order |
| Frontend SPA | routing structure, state management, component tree |
| Backend API | route definitions, middleware chain, data models |
| CLI Tool | command structure, argument parsing, subcommands |
