[rig-sampler] Daily Rig sample report — 2026-10-19

Start by reading skills/rig/samples/110-workspace-config-drift-3.md and the stdin input schema for the root agent it invokes. Reproduce the sample failure and locate where the root agent's input is configured. Done when the sample runs successfully and emits its expected output; the report does not include that expected output.

Selected samples

4 of 5 succeeded.

Expected stdin program root agent to have no input (omit input or use input: s.object({})).

Rig Runtime Logs

Captured from a single run of the program. The coordinator is first, followed by each sample's own inner-run log lines. Sample 5 emitted no rig.* lines (it failed before an agent was invoked).
