analyze-codebase（分析代码库）

Analyze Codebase

Understand any codebase quickly.

Analysis Types

Architecture Overview

"What's the architecture of this codebase?"

Agents analyze:
- Entry points
- Layer structure
- Data flow
- Dependencies
- Key abstractions

Pattern Inventory

"What patterns does this codebase use?"

Agents find:
- Design patterns (MVVM, etc.)
- Code conventions
- Naming schemes
- File organization
- Common idioms

Health Check

"How healthy is this codebase?"

Agents assess:
- Code complexity
- Test coverage
- Dead code
- Duplications
- Tech debt indicators

Dependency Map

"Map the dependencies"

Agents trace:
- Internal dependencies
- External packages
- Circular references
- Coupling points
- Isolated modules

Quick Commands

5-Minute Overview

"Quick overview: What does this codebase do?"

Returns:
- Purpose
- Main components
- Entry points
- Key files

Entry Point Discovery

"Where does execution start?"

For apps:
- main(), App.swift, index.ts
- Configuration loading
- Initialization sequence

Data Flow

"Trace data from [source] to [destination]"

Returns:
- Flow path
- Transformations
- Storage points
- Exit points

Agent Deployment

Parallel Exploration

Spawn 5 agents:
1. Structure analyzer (files, folders)
2. Entry point finder
3. Pattern identifier
4. Dependency mapper
5. Test coverage checker

Results in <1 minute.

Integration with Memory

Store Findings

After analysis:
"Remember: [key insight]"

Never re-analyze for the same question.

Update CLAUDE.md

Add architecture notes:
- Key abstractions
- Important patterns

Example Prompt

Analyze this iOS codebase:

1. What's the architecture pattern?
2. How is state managed?
3. Where's the networking code?
4. What persistence is used?
5. How are views structured?

Return a concise overview I can reference.
