+
+# /save-plan — Save Plan to Disk
+
+Save the current in-memory plan to disk (mirroring spec structure under `docs/plans/`).
+
+---
+
+## Syntax
+
+```bash
+/save-plan --spec @<original-spec-path>
+```
+
+- `--spec @<original-spec-path>` (required): Original spec path to mirror structure
+
+---
+
+## Behavior
+
+1) Read the current in-memory plan from Cursor's Plan mode.
+2) Determine output path by mirroring the spec's subpath:
+   - Spec: `docs/specs/<subpath>/<filename>.md`
+   - Plan: `docs/plans/<subpath>/<filename>.md`
+3) Ensure parent directories exist; write the plan atomically.
+4) Return saved plan path.
+
+---
+
+## Prerequisites
+
+- Cursor is in Plan mode with an active plan
+- Original spec exists at the provided path
+
+---
+
+## Usage
+
+After generating a plan in Plan mode:
+
+```bash
+/save-plan --spec @docs/specs/888568-language-content-service-implementation-execute/920755-export-to-excel-backend-frontend-and-filters.md
+```
+
+This writes plan to: `docs/plans/888568-language-content-service-implementation-execute/920755-export-to-excel-backend-frontend-and-filters.md`
+
+---
+
+## Example
+
+Command:
+```bash
+/save-plan --spec @docs/specs/924274-jadx-test/924326-dashboard-export-to-excel.md
+```
+
+Result:
+- Plan saved to `docs/plans/924274-jadx-test/924326-dashboard-export-to-excel.md`
+
+---
+
+## Notes
+
+- Only works when a plan exists in memory (Plan mode)
+- If plan file already exists, it's overwritten
+- Preserves the original plan structure and todos as-is
