# Analyze Codebases With Structured Overviews

Unfamiliar repositories slow onboarding, reviews, and documentation work. This skill guides Claude, Codex, and Claude Code through structured architecture analysis.

## Capabilities

- Identifies main directories, configuration files, and entry points.
- Reviews package, dependency, build, and deployment files.
- Maps core modules, services, classes, and responsibilities.
- Explains component interactions, APIs, and data flow.
- Summarizes deployment setup, environments, and infrastructure signals.
- Describes startup flow, request handling, errors, and background work.

## Use Cases

- Understand a new repository: Create a clear map of project structure, entry points, components, and runtime flow.
- Draft system documentation: Turn repository evidence into concise architecture notes and operational explanations.
- Review existing architecture: Compare modules, dependencies, deployment signals, and service boundaries before planning changes.

## Prompt Templates

### Basic Repository Overview

```
Explain this codebase at a high level. Cover the main folders, entry points, and major components.
```

### Component Interaction Map

```
Analyze the core components in this repository. Explain their responsibilities, interfaces, and data flow.
```

### Deployment And Runtime Review

```
Review this project for deployment architecture and runtime behavior. Include startup flow, environments, dependencies, and error handling.
```

### Full Technical Architecture Brief

```
Create a complete technical architecture brief for this repository. Include structure, dependencies, components, interactions, deployment, and runtime behavior.
```

## Limitations

- Does not execute code, run tests, or validate runtime behavior.
- Does not modify project files or produce implementation changes by default.
- Accuracy depends on available files and readable project structure.
- Large repositories may need focused follow-up questions.

## Best Practices

- Start with repository structure before reading detailed source files.
- Use configuration and dependency files to identify frameworks and deployment signals.
- Trace runtime flow from entry points through core components.

## Anti Patterns

- Do not treat a single file as the full system design.
- Do not recommend implementation changes unless the user asks for them.
- Do not skip deployment files when explaining production behavior.

## Security Audit

- Audited at: 2026-07-06T19:58:42.449\+00:00
- Summary: Reviewed SKILL.md and EVALUATION.json for the two static alerts. Both alerts are false positives caused by benign documentation language about codebase analysis. No semantic prompt injection, data exfiltration, code execution, network use, or file modification intent was found.
