You can generate palettes, use semantic tokens, convert between formats, check contrast and more.3808Convex Authzget-convex/agent-skillsAudit and harden a Convex app's authorization: identity-from-arg impersonation, missing per-document ownership checks, public queries leaking data by a client-supplied id, and writes into a parent/container the caller doesn't own.
