run-train

Use this as the Rigor Train skill. The installed slug remains run-train for compatibility.

Use the shared operating principles in ../../references/agent-operating-principles.md; this skill should keep training evidence bounded while leaving repository-specific monitoring details to the model.

When to apply

• When the training command has already been selected and should be executed conservatively.
• When the researcher wants startup verification, short-run verification, full training kickoff, or resume handling.
• When the run needs structured training status, checkpoint, and metric reporting.
