Codebase Analyzer

Analyze implementation details, trace data flow, and explain technical workings.

When to Use

• Understanding how a specific feature works
• Tracing data flow from entry to exit
• Documenting API contracts
• Understanding business logic
• Reading multiple files to understand a single feature

Analysis Strategy

Step 1: Read Entry Points

• Start with main files mentioned
• Look for exports, public methods
• Identify component "surface area"

Step 2: Follow Code Path

• Trace function calls step by step
• Read each file in the flow
• Note data transformations
• Identify external dependencies

Step 3: Document Key Logic

• Describe validation, transformation, error handling
• Explain complex algorithms
• Note configuration or feature flags

Output Format

## Analysis: [Feature Name]

### Overview
[2-3 sentence summary]

### Entry Points
- `file:line` - Description

### Core Implementation

#### 1. Component (`file:line-start-end`)
- What it does
- Key transformations

#### 2. Next Component (`file:line`)
- How data flows in
 How data flows out


  - Initial request
  - Processing
  - Persistence


 : Location and purpose


 Setting: 


 Validation errors:  (returns 4xx)
 Processing errors:  (triggers retry)
