## trace Tool Routing

- IMPORTANT: For ANY code exploration task, ALWAYS use trace tools first. NEVER use Read/Grep/Glob/Bash(ls,find) for navigating source code.

| Task | trace tool | Instead of |

|------|------------|------------|

- | Find a function/class/method | `search` | Grep |

- | Understand a file before editing | `get_outline` | Read (full file) |

- | Read one symbol's source | `get_symbol` | Read (full file) |

+ | Find a function/class/method | `search` | text grep |

+ | Understand a file before editing | `get_outline` | full-file read |

+ | Read one symbol's source | `get_symbol` | full-file read |

| What breaks if I change X | `get_change_impact` | guessing |

- | All usages of a symbol | `find_usages` | Grep |

- | All implementations of an interface | `get_implementations` | ls/find on directories |

- | All classes implementing X | `search` with `implements` filter | Grep |

+ | All usages of a symbol | `find_usages` | text grep |

| Project health / coverage gaps | `self_audit` | manual inspection |

- | Dead code / dead exports | `get_dead_code` (`mode: "exports_only"`) | Grep for unused |

| Context for a task | `get_feature_context` | reading 15 files |

- | Tests for a symbol | `get_tests_for` | Glob + Grep |

| Untested symbols (deep) | `get_untested_symbols` (deferred — load via `load_tools`) | manual audit |

| HTTP request flow | `get_request_flow` (framework-gated) | reading route files |

| DB model relationships | `get_model_context` (framework-gated) | reading model + migrations |

| Component tree | `get_component_tree` (framework-gated) | reading component files |

| Circular dependencies | `get_circular_imports` | manual tracing |

+ | Task spanning many turns | `trace_state_init` once, then `trace_state_patch` / `trace_state_add_dead_end` per step, `trace_state_get` to re-read (deferred — `load_tools({preset:"state"})`) | re-reading the whole transcript every turn |

- Use Read/Grep/Glob ONLY for non-code files (.md, .json, .yaml, config) or before Edit.

+ Use host file-reading and grep tools ONLY for non-code files (.md, .json, .yaml, config) or before edit.
