Index a repository into the knowledge graph. Special mode 'cross-repo-intelligence': skip extraction, only match Routes/Channels across projects to create CROSS_HTTP_CALLS/CROSS_ASYNC_CALLS/CROSS_CHANNEL edges. Requires target_projects param. Ensure target projects have fresh indexes first.

Search the code knowledge graph for functions, classes, routes, and variables. Use INSTEAD OF grep/glob when finding code definitions, implementations, or relationships. Three search modes: (1) query='update settings' for BM25 ranked full-text search with camelCase splitting and structural label boosting — recommended for natural-language discovery; (2) name_pattern='.regex.' for exact pattern matching; (3) semantic_query=[...] for vector cosine search that bridges vocabulary (finds 'publish' when you search 'send'). The three modes are independent and can be combined in a single call. PAGINATION: results are capped at limit (default 200) — broader queries are silently truncated. The response always includes 'total' (full match count before limit) and 'has_more' (true when total > offset+returned). Detect truncation with has_more, then page by re-calling with offset=offset+limit until has_more is false. Narrow first via label/file_pattern/min_degree before paginating large result sets.

Execute a Cypher query against the knowledge graph for complex multi-hop patterns, aggregations, and cross-service analysis. The response includes 'total' (returned row count). There is a hard 100k row ceiling — for broad queries add LIMIT in the Cypher itself or use search_graph + offset/limit pagination instead.

Trace paths through the code graph. Modes: calls (callers/callees), data_flow (value propagation with args at each hop), cross_service (through HTTP/async Route nodes). Use INSTEAD OF grep for callers, dependencies, impact analysis, or data flow tracing.

Read source code for a function/class/symbol. IMPORTANT: First call search_graph to find the exact qualified_name, then pass it here. This is a read tool, not a search tool. Accepts full qualified_name (exact match) or short function name (returns suggestions if ambiguous).

Graph-augmented code search. Finds text patterns via grep, then enriches results with the knowledge graph: deduplicates matches into containing functions, ranks by structural importance (definitions first, popular functions next, tests last). Modes: compact (default, signatures only — token efficient), full (with source), files (just file paths). Use path_filter regex to scope results. TRUNCATION: enriched results are capped at limit (default 10). Response carries 'total_grep_matches' (raw grep hit count) and 'total_results' (deduplicated function count) — compare to limit to detect truncation. There is no offset parameter; to see more, raise limit or narrow the query with file_pattern / path_filter.
