Implementation Reference
- src/tools/handlers.ts:241-281 (handler)The main handler function that implements the close_session tool logic. It takes session_id, calls sessionManager.closeSession, and returns success/error status.
/** * Handle close_session tool */ async handleCloseSession(args: { session_id: string }): Promise< ToolResult<{ status: string; message: string; session_id: string }> > { const { session_id } = args; log.info(`🔧 [TOOL] close_session called`); log.info(` Session ID: ${session_id}`); try { const closed = await this.sessionManager.closeSession(session_id); if (closed) { log.success(`✅ [TOOL] close_session completed`); return { success: true, data: { status: "success", message: `Session ${session_id} closed successfully`, session_id, }, }; } else { log.warning(`⚠️ [TOOL] Session ${session_id} not found`); return { success: false, error: `Session ${session_id} not found`, }; } } catch (error) { const errorMessage = error instanceof Error ? error.message : String(error); log.error(`❌ [TOOL] close_session failed: ${errorMessage}`); return { success: false, error: errorMessage, }; } } - Tool schema definition: name, description, and inputSchema requiring session_id.
