Unclear It is not clear whether the host feature check is switched on, so the ID may not be sent.
Claude Code reads a new environment variable, CLAUDE_CODE_PROGRAM_USE_CASE_ID, a setting you give it before it starts. When set, Claude Code attaches the ID to its requests only if:
- the value has the expected format
- the host supports the feature
- the host has not refused that ID
If the host refuses the ID, Claude Code fetches its startup information again.
This gives a way to label requests with the program or use case they come from.
