Common Gotchas
API keys: Most agents need keys passed via --ae. Claude Code needs ANTHROPIC_API_KEY, OpenHands needs LLM_API_KEY, Goose needs provider-specific keys. If the agent fails immediately, check the key.
Docker must be running. Harbor uses Docker for sandboxed environments. Network exhaustion from many concurrent trials can cause failures -- harbor cache clean helps.
Model name format varies by agent. Claude Code uses anthropic/claude-sonnet-4-1, Cline CLI uses provider:model-id (e.g., openrouter:anthropic/claude-opus-4.5), Goose uses provider/model_name. A ValueError about model format usually means the wrong format for that agent.
--env vs --environment-type: harbor run uses --env / -e. harbor trials start uses --environment-type / -e. Same short flag, different long name.
Default agent is oracle. Forgetting -a gives you the oracle agent, which just runs solve.sh. Fine for task validation, not for real evaluations.
--no-cleanup for debugging. Pass this to harbor trials start to keep the container running after a failed trial so you can inspect it.
Retry defaults skip common errors. --retry-exclude defaults to AgentTimeoutError, VerifierTimeoutError, RewardFileNotFoundError, RewardFileEmptyError, VerifierOutputParseError. These usually indicate task bugs, not transient failures.
