# Behavioral regression testing for agent skills.
# Default (PR): runs recorded-trace scenarios only — deterministic, no quota, no secrets.
# Manual (workflow_dispatch): additionally runs live scenarios via the Freebuff/Codebuff
# harness using a CODEBUFF_API_KEY repo secret (costs credits; gated behind manual trigger).
