conductor: OpenRouter exec produced empty final response — agent completed work but returned no final message is a OpenRouter failure pattern reported for developers trying to debug why openrouter returns empty final response after agent completes task successfully in conductor orchestrator. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

conductor exec --with openrouter returned exit code 1 with 'OpenRouter exec produced empty final response'. The agent's work in the worktree was complete but no final message was returned. Not an iter-cap or stall issue.

Common causes

OpenRouter occasionally produces empty final responses even when the agent has completed its work. The conductor fails with exit code 1, losing all completed work context. Distinct from timeout or iteration-cap errors.

Quick fixes

Confirm the exact error signature matches conductor: OpenRouter exec produced empty final response — agent completed work but returned no final message.
Check the OpenRouter account, local tool state, and provider configuration involved in the failing workflow.
Compare the failing environment with a known working setup, then change one configuration value at a time.

Platform/tool-specific checks

Verify the command, editor, extension, or API client that produced the error.
Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
Avoid deleting credentials, local model data, or project settings until the failing scope is clear.
