| 1 | """``muse code-query`` — predicate query over code commit history. |
| 2 | |
| 3 | Search the commit graph for code changes matching a structured predicate:: |
| 4 | |
| 5 | muse code-query "symbol == 'my_function' and change == 'added'" |
| 6 | muse code-query "language == 'Python' and author == 'agent-x'" |
| 7 | muse code-query "agent_id == 'claude' and sem_ver_bump == 'major'" |
| 8 | muse code-query "file == 'src/core.py'" |
| 9 | muse code-query "change == 'removed' and kind == 'class'" |
| 10 | muse code-query "model_id contains 'claude'" |
| 11 | |
| 12 | Fields |
| 13 | ------ |
| 14 | |
| 15 | ``symbol`` Qualified symbol name (e.g. ``"MyClass.method"``). |
| 16 | ``file`` Workspace-relative file path. |
| 17 | ``language`` Language name (``"Python"``, ``"TypeScript"``…). |
| 18 | ``kind`` Symbol kind (``"function"``, ``"class"``, ``"method"``…). |
| 19 | ``change`` ``"added"``, ``"removed"``, or ``"modified"``. |
| 20 | ``author`` Commit author string. |
| 21 | ``agent_id`` Agent identity from commit provenance. |
| 22 | ``model_id`` Model ID from commit provenance. |
| 23 | ``toolchain_id`` Toolchain string from commit provenance. |
| 24 | ``sem_ver_bump`` ``"none"``, ``"patch"``, ``"minor"``, or ``"major"``. |
| 25 | ``branch`` Branch name. |
| 26 | |
| 27 | Operators: ``==``, ``!=``, ``contains``, ``startswith`` |
| 28 | |
| 29 | Usage:: |
