RepoLens

What is RepoLens?

RepoLens helps you understand software repositories faster by analyzing a codebase and turning what it finds into navigable structure and developer-facing documentation. It can inspect repositories, explore how modules relate, and surface dependencies and APIs so you can ask questions with grounded context.

The core purpose is to reduce the time spent mapping unfamiliar projects—by generating module maps, architecture documentation, and summaries based on the repository content.

Key Features

• Repository analysis to extract actionable information from an existing codebase, helping you build an overview before reading everything line by line.
• Module map exploration, which organizes how parts of the system relate so you can navigate the code more efficiently.
• Dependency inspection to reveal what modules depend on, clarifying coupling and execution flow at a high level.
• API extraction to identify callable interfaces in the repository, providing a starting point for integration and usage.
• Architecture documentation generation that compiles findings into docs intended to explain the system’s structure.
• Grounded Q&A that answers questions based on what the tool finds in the repository, rather than generalities.

How to Use RepoLens

1. Provide RepoLens access to the repository you want to understand.
2. Run repository analysis to generate module maps and dependency information.
3. Use the tool’s API extraction and architecture documentation outputs to identify key components and how they interact.
4. Ask questions about the codebase using RepoLens so responses are tied to the analyzed repository content.

Use Cases

• Onboarding to a new project: quickly learn the repository’s structure using module maps, dependency views, and generated architecture documentation.
• Preparing integration work: identify relevant APIs through API extraction to understand what to call and where those interfaces live in the codebase.
• Debugging and impact analysis: check dependencies and module relationships to understand how a change in one area may affect other parts.
• Writing internal documentation: generate architecture docs that reflect the repository’s current structure and components.
• Asking specific codebase questions: query for how a component works or where functionality is implemented with answers grounded in repository analysis.

FAQ

What kinds of information does RepoLens extract from a repository?

RepoLens analyzes repositories to produce module maps, dependency information, API extraction, and architecture documentation.

Does RepoLens support Q&A about the codebase?

Yes. RepoLens supports grounded questions that are based on the analyzed repository content.

What does “module map” mean in RepoLens?

In this context, a module map is a structured view of how modules in the repository relate, intended to help you navigate the codebase more effectively.

Can RepoLens help with documentation writing?

Yes. RepoLens can generate architecture documentation based on the repository’s analyzed structure.

Alternatives

• Generic code search tools (e.g., repository-wide grep/search): useful for finding symbols quickly, but typically require more manual effort to reconstruct architecture and dependencies.
• Static analysis and dependency graph tools: good for visualizing dependency relationships, though they may not provide API extraction and narrative architecture documentation.
• AI code assistants focused on chat without repository-wide analysis: may help with targeted questions but may be less effective at producing structured module maps and documentation grounded in the full codebase.
• Documentation generation tools based on code comments or annotations: can produce reference docs for APIs, but may not create the same module-level maps and dependency-aware architecture summaries.
