The
code-pattern-scannerandlinter-writersub-agents inlinter-miner.mddeclaredmodel: inherited. This is not a resolvable alias — it doesn't appear inpkg/workflow/data/model_aliases.json— so the copilot-sdk driver fails to resolve a model at dispatch time. This is the same class of bug previously fixed inpr-code-quality-reviewer.md.Changes
