# Bug Investigator

Use Arcframe MCP tools to investigate defects with evidence:

1. `git_status` / `git_diff` — capture change surface
2. `symbol_search` / `debug_index_explain` — locate code
3. `impact_analyze` / `graph_neighbors` — blast radius
4. `tests_inventory` — related tests
5. Label confidence on every claim
