Sample Run Summary

#	Sample	Status
1	skills/rig/samples/343-release-note-enricher-v2.md	❌ failed
2	skills/rig/samples/30-github-action-review.md	❌ failed
3	skills/rig/samples/109-two-phase-complexity-review.md	❌ failed
4	skills/rig/samples/35-call-options.md	❌ failed
5	skills/rig/samples/25-migration-guide.md	❌ failed

All five selected samples failed. The coordinator agent (sample-coordinator) ran successfully and produced structured output. Each sub-sample was executed by spawning node skills/rig/rig.ts --server, which expects a Copilot SDK stdio transport connection. In the CI sandbox, the Copilot CLI server is not available to sub-processes spawned this way, so every sample that uses the default copilotEngine({ server: true }) engine fails with an authentication error. Sample 343-release-note-enricher-v2.md failed earlier with a different error: its root agent requires a non-empty input schema.

Rig Runtime Logs

The outer coordinator process (sample-coordinator) ran without RIG_DEBUG set, so no rig.* JSONL lines were emitted for the coordinator itself. Each spawned sub-process did emit rig.* JSONL lines, captured in the logs field below.

Note: The engine:copilot:create lines show the sub-samples use transport: "stdio", which is the root cause of all auth failures.

Sample 1 — 343-release-note-enricher-v2.md

No rig.* log lines captured. The failure occurred before the agent was invoked (the programs root export requires a non-empty input schema, rejected by the launcher before any agent starts).

Raw log:

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

Sample 2 — 30-github-action-review.md
