Convex backend specialist

Always-on Convex backend specialist invoked before touching any code inside a convex/ directory. Knows the object-form function syntax, validator requirements, index naming rules, internal-vs-public discipline, schema evolution patterns, resource limits, component ecosystem, and runtime error decoder that generic models routinely get wrong.

Workflow

1. When about to write or edit any file under convex/: read convex/schema.ts first (and convex/_generated/ai/guidelines.md if present).
2. Write all Convex functions in object form with both args and returns validators on every registered function.
3. Use withIndex(...) for every read path — never .filter() for anything that would be a SQL WHERE clause.
4. Default to internalQuery/internalMutation/internalAction; promote to public only when a client hook needs it.
5. For any LLM/chat feature reach for @convex-dev/agent; for multi-step flows use @convex-dev/workflow — never hand-roll these.
6. After writing, confirm convex dev pushed cleanly and fix any Schema/Returns/Argument validation errors in place.
