+description: Configuration and cache management
+argument-hint: <show-cache-dir|clear-cache> [options]
+---
+
+Manage Arcaneum configuration and model cache.
+
+**Subcommands:**
+
+- show-cache-dir: Display cache locations and sizes
+- clear-cache: Clear model cache to free disk space
+
+**Arguments:**
+
+- --confirm: Confirm cache deletion (required for clear-cache)
+
+**Examples:**
+
+```text
+/config show-cache-dir
+/config clear-cache --confirm
+```
+
+**Execution:**
+
+```bash
+cd ${CLAUDE_PLUGIN_ROOT}
+arc config $ARGUMENTS
+```
+
+**Note:** The model cache (~/.arcaneum/models/) stores downloaded embedding models.
+First-time indexing downloads ~1-2GB of models which are then reused. I'll show you:
+
+- Current cache directory locations
+- Size of each directory (models, data)
+- Free disk space information
+
+Use clear-cache when models are corrupted or to free disk space (models will
+be re-downloaded on next use).
+
+**Related:**
+
+- Models auto-downloaded to ~/.arcaneum/models/
+- Data stored in ~/.arcaneum/data/
+- Implemented in arcaneum-157 and arcaneum-162
