Sample Outputs

07-summarize-many-files.md — ✅ succeeded

{"summary":"The repository contains a TypeScript agent harness (rig) with a core runtime, 50+ sample agents in src/samples/, engine-specific unit tests (Copilot, Gemini, Anthropic, Codex), launcher fixtures, skill documentation under skills/rig/, and standard project config files (tsconfig, package.json, .gitignore)."}

147-git-submodule-health.md — ✅ succeeded

{"submodules":[],"allClean":true,"totalCount":0}

393-ssh-config-host-parser.md — ✅ succeeded

{}

374-ts-type-guard-generator.md — ❌ failed

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

The sample defines a root agent with a required input schema, which is incompatible with stdin-mode execution.

404-git-diff-word-frequency.md — ❌ failed

Agent agent output validation failed: $.mostFrequentAddition: optional field must be omitted or a valid value, not null (use s.nullable to allow null)

The model returned null for the optional field mostFrequentAddition, but the schema uses s.optional which disallows null. The fix would be to use s.nullable(s.string) or s.optional(s.nullable(s.string)).
