About semantic-search

The Semantic Search Skill allows users to perform natural language searches on codebases, enabling them to detect patterns, find similar code, and analyze code semantics. This skill solves the problem of relying on exact text matching for code searches by leveraging semantic understanding, making it possible to search and analyze code by its meaning, relationships, and structure rather than simple keyword matching. It helps developers gain insights into their codebases more efficiently and accurately, facilitating better code management and understanding.

FAQ

How do I perform a natural language search with this skill?

You can use the `search` operation and provide a natural language query (e.g., 'database connection functions') along with the codebase path. The skill will return relevant code snippets and functions based on the query.

What is the minimum similarity required to detect duplicate code?

For detecting duplicate code, the skill compares code blocks and uses a similarity threshold of 0.85 by default. This means that only blocks of code with at least 85% similarity will be flagged as duplicates.

Does this skill support all programming languages?

The skill supports any codebase that can be parsed and understood by the underlying tools, but the effectiveness of semantic analysis depends on the specific programming languages and their support in the environment.

Can I adjust the search results and similarity threshold?

Yes, the skill allows you to configure parameters such as `max_results`, `similarity_threshold`, and other settings like including comments and defining minimum pattern occurrences through the configuration file.
