Implementation Reference
- src/index.ts:53-60 (registration)Registration of the 'list_undos' tool in the TOOLS array, including name, description, and empty input schema.
{ name: "list_undos", description: "List all undo checkpoints in the stack", inputSchema: { type: "object", properties: {}, }, }, - src/index.ts:119-129 (handler)Tool handler for 'list_undos': invokes changeTracker.listUndoStack() and returns formatted response content.
case "list_undos": { const undoList = changeTracker.listUndoStack(); return { content: [ { type: "text", text: `Undo Stack:\n${undoList.join('\n\n')}`, }, ], }; } - src/changeTracker.ts:145-175 (helper)Implementation of listUndoStack() in ChangeTracker class: deduplicates checkpoints, formats and returns list of undo stack entries with details.
