name: Generate Sample Outputs

# Generates real model outputs for the sample-output gallery using the
# ANTHROPIC_API_KEY repo secret — the key never leaves GitHub. Generates a
# sample for every eval-case skill that doesn't already have one (it never
# overwrites hand-written samples), rebuilds web/samples.json, and commits.
#
# Run it from the Actions tab → "Generate Sample Outputs" → Run workflow.

            Auto-generated by the **Generate Sample Outputs** workflow using the
            ANTHROPIC_API_KEY secret. Adds real model outputs to the sample gallery
            (examples.html). Hand-written samples are never overwritten.
