summary: "Single-agent baseline that hands the whole search loop to one Claude Code CLI session, run inside the task's own container image by default (subscription-only billing): Claude edits the solution and runs the task's own evaluator, and the framework scores checkpoints with that same evaluator. A run scored on the host (general.eval_mode: local) gets the session as a host subprocess instead."
source: "Galapagos synthesis of SkyDiscover's claude_code controller and Harbor's installed-agent model: the agent and sealed evaluator share the task container, with the agent running non-root and /eval remaining root-owned"
