Trainer Train

Use this skill as the orchestration contract for one trainer run against one selected target. Treat the concrete research, synthesis, optimization, and election capabilities as caller-supplied stage implementations. This skill owns the loop behavior, workspace state, steering, validation, and write-back rules around those stages.

Before you start

• Read references/workspace-contract.md, references/stage-orchestration.md, and references/collaboration-contract.md before broad changes or stage execution.
• Consult those references whenever stage sequencing, artifact paths, scoring behavior, or ownership boundaries are uncertain.
• Do not improvise artifact paths, stage order, or write-back gates from memory.

Target-type delegation

Before running the loop, identify the selected target type and read references/target-routing.md to determine whether a specialist trainer should handle this target instead. Specialists own target-specific workspace rules, judge-mode defaults, and write-back constraints for their domain.

Use this generic skill only when the target does not match any specialist category, the caller explicitly bypasses delegation, or the relevant specialist is unavailable.
