Use it to understand how CodeWeaver’s Hybrid Search (Semantic + AST + Keyword) provides high-precision snippets. It saves 60–80% of token costs by eliminating irrelevant code from your agent’s context. AI agents often fail because they receive too much noise. When you provide a whole file for a single-function fix, you waste tokens, increase costs, and confuse the model. CodeWeaver solves this by delivering **Exquisite Context**—the exact structural and semantic matches an agent needs to perform its task. --- ## The 60–80% Context Reduction [Section titled “The 60–80% Context Reduction”](#the-6080-context-reduction) Traditional search tools often return thousands of tokens of irrelevant code. CodeWeaver uses a multi-signal approach to filter out the noise, typically reducing the context size by **60–80%** while maintaining over **90% relevance.** ### Why It Matters [Section titled “Why It Matters”](#why-it-matters) - **Lower Costs:** Fewer tokens mean smaller bills from LLM providers. - **Higher Accuracy:** Agents are less likely to hallucinate when focused on specific, relevant code. - **Faster Responses:** Smaller prompts result in faster processing and response times. --- ## The Hybrid Search Pipeline [Section titled “The Hybrid Search Pipeline”](#the-hybrid-search-pipeline) CodeWeaver doesn’t just look for keywords. It combines three distinct signals into a single, unified search result: ### 1. Semantic Search (Dense Embeddings) [Section titled “1. Semantic Search (Dense Embeddings)”](#1-semantic-search-dense-embeddings) Captures the **intent** of your query. If you search for “user login,” semantic search finds code related to authentication, even if the word “login” isn’t in the file. ### 2. Keyword Search (Sparse Embeddings) [Section titled “2. Keyword Search (Sparse Embeddings)”](#2-keyword-search-sparse-embeddings) Captures the **specifics**. Sparse embeddings act like a high-performance keyword index (BM25), ensuring that exact matches for function names, variable names, and error codes are never missed. ### 3. Structural Analysis (AST) [Section titled “3. Structural Analysis (AST)”](#3-structural-analysis-ast) Captures the **hierarchy**. CodeWeaver understands that a function belongs to a class, and that class belongs to a module. By leveraging Abstract Syntax Trees (AST) for 27 languages, CodeWeaver identifies logical boundaries and relationships that simple text search ignores. --- ## How It Works: Unified Ranking [Section titled “How It Works: Unified Ranking”](#how-it-works-unified-ranking) When you perform a search, CodeWeaver executes these signals in parallel. The results are then combined using **Reciprocal Rank Fusion (RRF)** and weighted based on your configuration. 1. **Retrieve:** Query dense and sparse vectors simultaneously. 1. **Analyze:** Apply AST-aware filters to ensure code snippets are logical and complete. 1. **Rank:** Use RRF to normalize scores across different signal types. 1. **Rerank (Optional):** Use a dedicated reranking model (like Voyage AI or Cohere) to perform a final “sanity check” on the top results. --- ## Span-Based Precision [Section titled “Span-Based Precision”](#span-based-precision) Unlike tools that return arbitrary “chunks” of text, CodeWeaver uses an immutable **Span-Based Architecture**. Each search result is a precise coordinate (file, line, column) that accurately represents the code’s location in your project. This allows agents to understand exactly where to apply their changes without guesswork. --- ## Summary: Curation over Collection [Section titled “Summary: Curation over Collection”](#summary-curation-over-collection) “Exquisite Context” is about **curation**, not just collection. By providing AI agents with high-precision, structurally-aware snippets, CodeWeaver enables them to work deeper, faster, and more reliably in complex codebases.
