Log completed work:

"Create a time entry for today 9:00-11:30 on the API project, tagged as development"

Get a weekly report:

"Show me a report of this week's hours grouped by project"

Check what's running:

"Is there a timer running?"

Troubleshooting

"Authentication failed"

Your SOLIDTIME_API_TOKEN is invalid or expired. Generate a new one in SolidTime under Settings > API.

"Permission denied"

Your token doesn't have access to the specified organization. Verify SOLIDTIME_ORGANIZATION_ID.

"Cannot reach SolidTime"

Check that SOLIDTIME_API_URL is correct and the instance is accessible. For self-hosted: ensure the URL includes the protocol (e.g., https://solidtime.example.com).

"Could not find member for user"

The authenticated user is not a member of the specified organization. Check SOLIDTIME_ORGANIZATION_ID.
