MCP scheduled-tasks no longer appear in Routines panel after 2.1.80

Summary

After updating to Claude Code 2.1.80, locally-managed scheduled tasks (from the bundled scheduled-tasks MCP server, stored at ~/.claude/scheduled-tasks/<task>/SKILL.md) no longer appear in the Routines panel. They were visible in the previous version.

Verification that the scheduler is healthy

The scheduler itself is working correctly. Calling mcp__scheduled-tasks__list_scheduled_tasks from a session returns all tasks with valid nextRunAt and recent lastRunAt timestamps. Tasks are firing on schedule (e.g. an hourly pr-review-loop ran ~1h before this report). Only the UI surfacing is broken.

claude mcp list only enumerates user-configured MCP servers, so scheduled-tasks does not appear there — expected, since it's bundled.

Repro

1. Have one or more entries under ~/.claude/scheduled-tasks/<task>/SKILL.md
2. Update Claude Code Desktop to 2.1.80
3. Open the Routines panel in the sidebar

Expected: Bundled scheduled-tasks MCP entries appear in the Routines panel, as in the prior version.

Actual: Routines panel does not show the local scheduled tasks, even though the scheduler is firing them on time.

Environment

• Claude Code: 2.1.80
• OS: Windows
