Indexes source code repositories by parsing files into an queryable semantic structure, extracting symbols, definitions, and relationships across the codebase. Uses AST-based or language-aware parsing to build a searchable index that enables fast lookups of functions, classes, variables, and their dependencies without requiring full codebase loading into memory on each query.

Accepts natural language questions about code and translates them into semantic searches against the indexed codebase, returning relevant code snippets, definitions, or navigation paths. Bridges the gap between human intent and code structure by mapping natural language queries to symbol lookups, type information, and dependency relationships without requiring users to know exact syntax or file paths.

Resolves symbol references and dependencies within the indexed codebase, enabling navigation from a symbol usage to its definition, or from a definition to all its usages. Maintains a graph of code relationships (imports, function calls, class inheritance) that allows traversal across files and modules to understand code flow and impact analysis.

Provides parsing and indexing capabilities across multiple programming languages within a single codebase, using language-specific parsers or a unified parsing abstraction to extract symbols and structure from heterogeneous code. Enables queries and navigation to work seamlessly across language boundaries in polyglot repositories without requiring separate tools per language.

Detects changes to source files and updates the index incrementally rather than requiring full re-indexing, using file watchers or change detection to identify modified, added, or deleted files and updating only affected symbols and references. Enables fast iteration during development without the overhead of re-parsing the entire codebase on every change.

Provides context-aware code completion suggestions based on the indexed codebase, using symbol information, type hints, and usage patterns to suggest relevant functions, classes, variables, and imports. Integrates with the code index to offer completions that are semantically relevant to the current context rather than generic suggestions.

Extracts and indexes documentation, comments, docstrings, and metadata from source code to enable documentation-aware search and navigation. Parses inline documentation, function signatures, and type annotations to build a knowledge base that enriches queries with contextual information about code purpose, parameters, and usage patterns.

Provides advanced search capabilities with filters and facets to narrow results by file type, language, symbol kind (function, class, variable), or other metadata. Enables users to construct complex queries combining natural language search with structured filters to find specific code patterns or definitions within large codebases.
