[rig-sampler] Daily Rig sample report — 2026-10-27

This is an auto-generated sample report, not a scoped task: three samples failed for two different reasons. Start by opening skills/rig/samples/419-json-schema-property-counter.md and skills/rig/samples/342-config-drift-reconciler-v2.md, whose stderr says the root agent must take no input (omit input or use input: s.object({})), and compare them with the sample definitions that pass. Then look at skills/rig/samples/520-multi-stage-churn-risk-pipeline.md, where churn-risk-analyzer returned no JSON value, and check the runner that invokes agents from the workflow. Done means saying which sample files need their input declaration fixed and which need their agent's output parsing fixed.

Selected samples

The coordinator program itself exited with code 0.
