Use custom providers when your endpoint uses an OpenAI-compatible, Anthropic-compatible, or Gemini-compatible format but is not one of Sleev's built-in providers. Most users should leave this unset.
Set the harness base URL to the local gateway with /sleev/<harness ID>/ followed by the provider's full API
base URL. Providers lists each harness
ID. For example, for OpenCode:
Use a full http or https base API URL. Include a
path such as /v1 only when it is part of the provider's API base.
See Harness Setup for where each harness
sets its base URL.
