[rig-sampler] Daily Rig sample report — 2026-10-21

Start by reading the three sample files named in the report that failed or produced empty results: skills/rig/samples/455-zlib-compression-analyzer.md, skills/rig/samples/277-ts-type-guard-generator.md, and skills/rig/samples/482-ts-mapped-type-extractor.md. Trace how the sample runner invokes each sample and compare the failing stdin agent setup with the successful samples. Done means the two failed samples run without the reported input error and produce nonempty output.

Selected samples

Overall: 3 succeeded, 2 failed. The coordinator exited with code 0.

Final outputs

{"types":{},"totalMappedTypes":0,"totalFiles":92}

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

Rig Runtime Logs

Captured from one run of the program with RIG_DEBUG enabled. Each sample's logs are grouped as the outer sample-runner lines from the coordinator process, followed by the sample's own inner process stderr lines (the logs field of its result).
