What's Wrong?

In Claude Cowork (Desktop), a custom skill that was deleted from Customize > Skills continues to appear in the "Skills" section of the context panel every time a scheduled task runs.

Verified the skill is gone from:

  • Customize > Skills (deleted)
  • Project folder and hidden subfolders (not found)
  • Project memory (empty)
  • Scheduled task prompt (no reference)

The deleted skill "agrinote-weekly-weather-v2" loads automatically on every scheduled task execution despite being removed everywhere accessible.

What Should Happen?

Deleted skills should not appear in any task context after deletion.

Error Messages/Logs

Steps to Reproduce

  1. Install a custom skill in Customize > Skills in Cowork
  2. Create a scheduled task linked to a Cowork project
  3. Delete the custom skill from Customize > Skills
  4. Run the scheduled task (manually or automatically)
  5. Check the right panel context during execution → The deleted skill reappears under "Skills" section

Additional Information

This issue only occurs during scheduled task execution. The skill does NOT appear in the project context panel when running tasks manually from the project view.

Recreating the scheduled task from scratch does not resolve the issue. The behavior is fully reproducible on every scheduled run.

extent analysis

TL;DR

The deleted custom skill reappears in the "Skills" section of the context panel during scheduled task execution, suggesting a potential caching or synchronization issue between the Customize > Skills section and the scheduled task configuration.

Guidance

  • Verify that the scheduled task configuration is updated correctly after deleting the custom skill from Customize > Skills, and check if there are any hidden or cached references to the deleted skill.
  • Investigate the possibility of a synchronization issue between the project folder, hidden subfolders, and the scheduled task configuration, as the skill is not found in these locations but still loads automatically.
  • Check the Anthropic API documentation to see if there are any specific requirements or limitations for updating scheduled task configurations or custom skill deletions.
  • Consider testing the behavior with a different custom skill to determine if the issue is specific to the "agrinote-weekly-weather-v2" skill or a more general problem.

Example

No code snippet is provided as the issue does not involve code modifications.

Notes

The issue is specific to scheduled task execution and does not occur when running tasks manually, suggesting a potential issue with the scheduling mechanism or the way tasks are configured.

Recommendation

Apply workaround: Try deleting and recreating the scheduled task after removing the custom skill from Customize > Skills to see if this resolves the issue, as recreating the task from scratch did not work in the initial attempt.
