convex

Provide comprehensive Convex development guidance to avoid common mistakes and ensure code compiles on first try. Key rules (full details in references/guide.md):

Functions: Import from ./_generated/server, use query({ args, handler }) syntax
Indexes: Never use .filter() - use .withIndex(). Never define by_creation_time index
Actions: Add "use node"; at top, never use ctx.db - use ctx.runQuery/ctx.runMutation
Scheduler: Auth does NOT propagate - use internal functions
React: Never call hooks conditionally - use "skip" pattern
