Native Runtime: codepilot_schedule_task and related builtin tools not available in any session

[DSVinC]

Description

In CodePilot's Native Runtime, the scheduled task / notification builtin tools (codepilot_schedule_task, codepilot_list_tasks, codepilot_cancel_task, codepilot_notify, codepilot_hatch_buddy) are not available in any chat session — neither in assistant mode nor in any other conversation.

The model prompt lists the harness extensions, and NotificationMcp (Native Runtime) is shown as a plugin (not executable), while all other CodePilot extensions (e.g. DashboardMcp, SessionSearchMcp, CliTools, MemorySearch) correctly show as executable.

Expected Behavior

Per src/lib/builtin-tools/index.ts, getToolGroups() registers codepilot-notify with condition: 'always', so these tools should be available in every non-heartbeat, non-plan session:

• codepilot_notify — send notification
• codepilot_schedule_task — create scheduled task (cron / interval / once)
• codepilot_list_tasks — list scheduled tasks
• codepilot_cancel_task — cancel a task
• codepilot_hatch_buddy — hatch buddy

Actual Behavior

The model's tool list does not include any of the above. The harness extension list shows:

- NotificationMcp (Native Runtime) (native plugin) — Detected in builtin-tools. Not executable...

while other Native Runtime tools correctly show:

- DashboardMcp (Native Runtime) (native plugin) — Detected in builtin-tools. Executable in current Runtime

Steps to Reproduce

1. Open CodePilot desktop app
2. Start any chat session (assistant mode or normal)
3. Ask the model to create a scheduled task, e.g. "帮我创建一个10分钟间隔的心跳任务"
4. The model cannot call any schedule/notify tool

Root Cause Investigation

From the source code (src/lib/builtin-tools/index.ts):

try {
  const { createNotificationTools, NOTIFICATION_SYSTEM_PROMPT } = require('./notification');
  groups.push({
    name: 'codepilot-notify',
    systemPrompt: NOTIFICATION_SYSTEM_PROMPT,
    condition: 'always',
    tools: createNotificationTools({
      sessionId: options.sessionId,
      workingDirectory: options.workspacePath,
    }),
  });
} catch { /* notification module not available */ }

The catch block is silent. It appears the require('./notification') is failing silently, so the group never gets registered.

Other tools with the same pattern (e.g. ./dashboard, ./session-search) work fine, so the issue is likely specific to the notification module — possibly a missing dependency (e.g. @/lib/notification-manager) that throws during require().

Suggested Fix

1. Add logging to the catch block so the failure is visible in dev/console:

   catch (err) {
     console.warn('[builtin-tools] Failed to load notification module:', err);
   }

2. Check if @/lib/notification-manager or any import in notification.ts has a missing dependency or circular import that causes silent failure.
