TL;DR

Update the update_scheduled_task function to properly handle file path validation when rewriting the SKILL.md file.

Guidance

• The issue seems to be related to the path-validation step when updating the prompt or description fields, which is causing a "path traversal detected" error.
• To verify, try updating only the enabled or cronExpression fields, which should succeed, and then try updating the prompt or description fields again to reproduce the error.
• A potential workaround is to manually edit the SKILL.md file directly, as described in the issue, to bypass the tool's path-validation step.
• Investigate the mcp__scheduled-tasks__update_scheduled_task function to see how it handles file path validation and rewriting of the SKILL.md file.

Example

No code snippet is provided as it is not clearly supported by the issue.

Notes

The issue seems to be specific to the darwin platform and Version: 2.1.128, so any fixes or workarounds may need to be tailored to this environment.

Recommendation

Apply workaround: Manually edit the SKILL.md file directly to bypass the tool's path-validation step, as this is a viable temporary solution until the underlying issue is fixed.
