Skill UI

A skill for mistake-proofing code, interfaces, schemas, and state machines so that misuse cannot be expressed. It helps design type-safe APIs, audit existing code for footguns, and fix recurring bugs by closing entire error classes. Covers concepts like making invalid states unrepresentable, parsing instead of validating, and distinguishing concepts that share a primitive.

Generate, refine, and validate diagrams from natural language, notes, code, or schemas. Supports Mermaid, Graphviz, and PlantUML for flowcharts, architecture, and state machines. Ideal for turning textual analysis into visuals, producing attack-path graphs, or creating editable diagram sources for reports and documentation.

This skill guide helps developers master best practices and architectural patterns for Godot 4 game development using GDScript. It thoroughly covers implementing game systems, managing complex state machines, utilizing signals, and optimizing performance. Use this when building robust, scalable, or advanced Godot games.

This skill enables authorized reverse engineering of custom binary protocols, Protobuf/gRPC schemas, and WebSocket frames using PCAP data. It helps recover undocumented wire protocols, decode structured traffic, and reconstruct state machines for security analysis and debugging purposes.

Review supervisor, swarm, planner-worker and parallel agent workflows as distributed state machines: task ownership, shared state, branch joins, retries, cancellation, context handoffs, budgets, deadlocks and human escalation before rollout.
