Oracle
Oracle adds an advisory second-model review with the selected files and real source context attached.
What it adds
The skill packages a prompt, file set, route claim, and budget context for a second frontier model, then returns a checkpointed advisory result for verification by the owning workflow.
How it works
Availability is established through its selected carrier. Sessions can be reattached by claim, files are selected explicitly, and the result is checked against the repository and tests before it influences a change.
Scope
Oracle advises. The repository workflow owns implementation, verification, and merge authority.
Source
Ships in the railyard plugin. Source: plugins/railyard/skills/oracle/SKILL.md.
Proof point
The source skill binds selected files and the review route to a digest-bound lifecycle.
