Implementation Reference
- src/tools/memory/updateMemory.ts:28-55 (handler)The main handler function that performs the update_memory tool logic: checks if memory exists, appends or replaces value using MemoryManager, returns success/error message.
export async function updateMemory(args: { key: string; value: string; append?: boolean }): Promise<ToolResult> { const { key: updateKey, value: updateValue, append = false } = args; try { const mm = MemoryManager.getInstance(); const existingMemory = mm.recall(updateKey); if (existingMemory) { const newValue = append ? existingMemory.value + ' ' + updateValue : updateValue; mm.update(updateKey, newValue); return { content: [{ type: 'text', text: `✓ ${append ? 'Appended to' : 'Updated'} memory: "${updateKey}"` }] }; } else { return { content: [{ type: 'text', text: `✗ Memory not found: "${updateKey}". Use save_memory to create new memory.` }] }; } } catch (error) { return { content: [{ type: 'text', text: `✗ Error: ${error instanceof Error ? error.message : 'Unknown error'}` }] }; } } - Input schema and metadata definition for the update_memory tool.
