Does Sema require manual indexing?

No, Sema automatically indexes your codebase on the first search, handling both keyword and semantic indices in the background without user intervention.

Does Sema support large projects?

Yes, Sema is designed for speed and efficiency, utilizing a background server that automatically shuts down after 30 minutes of inactivity to prevent resource waste.

How does impact analysis work in Sema?

Using the 'blast' command, Sema identifies the definition of a symbol and groups all its references across the project to show you exactly where changes will have an effect.

Can I filter searches by specific criteria?

Yes, you can filter results by language, file path globs, symbol kind (functions, classes), exported status, and cyclomatic complexity levels.

What is the difference between keyword and hybrid search?

Keyword search (BM25) is instant and best for specific identifiers, while hybrid search uses AI embedding models to understand the meaning behind natural language queries.

Developer Tools

Enables advanced semantic code search and deep structural intelligence within your codebase for Claude Code.

Sema empowers Claude Code with semantic understanding, allowing users to find logic by concept rather than just exact text. It automatically indexes codebases to provide high-speed hybrid search, symbol cross-referencing, and structural metadata queries—such as finding undocumented public functions or complex methods. This skill is essential for navigating large, unfamiliar codebases, performing impact analysis before refactors, and maintaining high code quality through structural auditing.

Key Features

01Hybrid Semantic Search: Combines natural language understanding with fast keyword matching for accurate discovery.

02Code Intelligence: Instantly locate symbol definitions, references, and exported members across the entire project.

03Structural Metadata Queries: Filter code by cyclomatic complexity, language, or documentation status.

041 GitHub stars

05Impact Analysis: Visualize how changes to a specific symbol might ripple through the project using the blast command.

06Auto-Indexing: Automatically builds and maintains a local vector index with zero manual setup required.

Use Cases

01Auditing code quality by identifying undocumented public functions or overly complex methods.

02Exploring a new codebase by asking natural language questions like 'Where is authentication handled?'.

03Refactoring code by finding all references and analyzing the blast radius of potential changes.
