## Overview Find code using hybrid BM25 + semantic search (RRF). Primary discovery tool — use before relationship or impact analysis. ## Quick Reference | Tool | Best For | |------|----------| | `find_code` | Natural-language queries, broad searches | | `find_symbol` | Exact identifier names | | `get_source_window` | Bounded source read when harness lacks `Read(offset, limit)` | > **Parameter types:** Numbers must be JSON numbers — not strings. ## `find_code` parameters | Param | Required | Default | Notes | |---|---|---|---| | `query` | yes | — | Natural language or symbol text | | `repo_id` | no | all repos | | | `limit` | no | 20 | Max 100 | | `file_path` | no | — | Path/directory substring filter | | `as_of` | no | now | ISO-8601 time-travel | | `include_diagnostics` | no | false | Set true for `id`, `score` in results | **No `kind` param on `find_code`** — use `find_symbol(kind=...)` to filter by symbol type. ```json { "query": "authentication middleware", "repo_id": "memdb", "limit": 20 } ``` ## `find_symbol` parameters | Param | Required | Default | Notes | |---|---|---|---| | `name` | yes | — | Symbol name to search | | `repo_id` | no | all repos | | | `fuzzy` | no | false | API field exists; currently exact-match in backend | | `edit_distance` | no | 2 | Only when fuzzy enabled | | `kind` | no | — | `Function`, `Class`, `Method`, etc. | | `file_path` | no | — | Path substring filter | | `limit` | no | 10 | Max 50 | ```json { "name": "validateToken", "repo_...
