Vellum Change Review

Review Stance

Prioritize bugs, behavioral regressions, security risks, migration gaps, broken package boundaries, and missing tests. Findings come before summaries. Avoid cosmetic feedback unless it affects correctness, maintainability, or user experience.

Required Checks

1. Inspect the actual diff before judging the change.
2. Identify which packages are affected: assistant, gateway, clients, cli, skills, packages, or meta.
3. Check package boundaries:
   • assistant must not import from gateway by relative path.
   • gateway must not import from assistant by relative path.
   • assistant and skills must not import each other directly.
   • Runtime code must not import from meta.
4. Check persistence changes:
   • DB schema or data changes need append-only DB migrations.
   • Workspace path, format, or file changes need append-only workspace migrations.
   • Migrations must be idempotent and registered.
5. Check feature flags:
   • New assistant flags must be declared in meta/feature-flags/feature-flag-registry.json.
   • Default-disabled or rollout-only features must not ship user-facing release notes.
