TL;DR

The issue with custom skills not being recognized on Claude Code on the web may be due to a configuration or compatibility issue with the Opus Claude Model.

Guidance

  • Verify that the custom skills are properly configured and enabled for the Opus Claude Model in the Claude Code settings.
  • Check the compatibility of the custom skills with the Opus Claude Model and the Anthropic API.
  • Investigate if there are any specific requirements or restrictions for custom skills on the web version of Claude Code.
  • Consider testing the custom skills with a different Claude Model to isolate the issue.

Example

No code snippet is provided as the issue does not contain sufficient technical details.

Notes

The lack of error messages or logs makes it challenging to pinpoint the exact cause of the issue. Further investigation and debugging may be necessary to resolve the problem.

Recommendation

Apply workaround: Try testing the custom skills with a different Claude Model or configuration to see if the issue persists, as the root cause is currently unclear.
