OpenAI Codex Rust coding patterns distilled from the codex-rs workspace. Use this skill whenever writing, reviewing, or refactoring Rust code — especially for async agents, CLI tools, sandboxing, Ratatui TUIs, JSON-RPC protocols, tokio-based services, or any codebase that needs defensive panic discipline. Trigger even when the user does not explicitly mention Codex, because the patterns generalize to any production Rust workspace. Covers async cancellation, error enum design, process sandboxing, Cargo workspace architecture, wiremock-based fakes, insta snapshot testing, OpenTelemetry tracing, and Ratatui rendering.
Write and refactor TypeScript code in repos that use Effect-TS services, Zod schemas, event-sourced persistence, and namespace-driven architecture. Use this skill when implementing features, fixing bugs, writing tests, or refactoring in opencode or any TypeScript codebase built on the same stack (Effect DI, Drizzle ORM, Hono routes, Bun runtime). Triggers on tasks involving Effect services, namespace modules, Zod schema definitions, SyncEvent patterns, tool implementations, test writing, or code review in Effect-based TypeScript projects.
Apply Cognitive Load Theory to optimize instructional design by managing intrinsic, extraneous, and germane load within working memory limits. Use this skill when the user needs to diagnose why learners are overwhelmed, redesign training or documentation for better comprehension, evaluate UI/UX information architecture for cognitive burden, or when they ask 'why is this tutorial confusing', 'how to simplify complex instructions', or 'what causes information overload'.
Explain blockchain fundamentals including distributed ledger architecture, consensus mechanisms, and block structure. Use this skill when the user needs to understand blockchain concepts, evaluate whether blockchain fits a use case, or design a blockchain-based solution — even if they say 'how does blockchain work', 'do I need blockchain', or 'distributed ledger'.
Generate a personalized learning document (FOR[yourname].md) that explains a project in plain, engaging Taiwan Traditional Chinese. Covers technical architecture, codebase structure, technologies, design decisions, and lessons learned. Use when user wants to understand a codebase deeply or create project documentation for learning purposes.
This skill should be used when a team wants to create or refine the technical guidelines document — for example "create the tech steering doc", "document our tech stack", "write the technical guidelines", "document our architecture decisions", "set up the tech steering", or "update the tech doc". Generates docs/steering/TECH.md as a living document capturing the stack, architecture patterns, constraints, commands, and ADRs. Generated once and refined — not regenerated from scratch.
Follow this sub-process for code optimization — handle tasks where 'behavior remains unchanged but structure changes' (structure / performance / readability). Shift single-module internal optimization from 'AI random refactoring' to 'first scan to generate a checklist, confirm each item with the user, execute step by step according to the method library, and obtain manual approval for each step'. Trigger scenarios: When the user mentions phrases like 'optimize / refactor / rewrite / split / poor performance / too long code' without any accompanying behavior changes. Do not handle new requirements (route to feature), bugs (route to issue), or cross-module architecture restructuring (route to architecture + decisions).
A fast diagramming tool developed by ProcessOn that allows you to quickly create beautiful, editable visual diagrams such as flowcharts, swimlane diagrams, sequence diagrams, architecture diagrams, ER diagrams, organizational charts, timelines, and infographics. It supports direct rendering of Mermaid data. Generate, edit, and visualize professional ProcessOn diagrams from natural language descriptions. Use this tool when users request to "create a diagram", "make a flowchart", "visualize a process", or "draw a system architecture". It comprehensively supports generating process flowcharts (including swimlane and process maps for business workflows), sequence diagrams (for system interactions and API call orders), software architecture diagrams (for cloud architecture and system composition), ER diagrams (for database modeling), org charts (for team structures), timelines, and infographics. This AI diagram generator and flowchart maker is designed for developers, managers, and designers to achieve publication-ready visual outputs efficiently.
Generate a STRIDE-based security threat model for a repository. Use when setting up security monitoring, after architecture changes, or for security audits.
Behavior Guidelines for Information Visualization Presentation. Automatically activated when the model's response contains structured information such as comparisons, steps, configurations, architectures, etc., ensuring priority use of visual formats like tables, code blocks, lists, tree structures, instead of pure text accumulation. Trigger words: "Use a table", "Draw a diagram", "Make a list", "Structure it", "Don't just use text", "Visualize", "Compare". Even without trigger words, the rules of this Skill should take effect as long as the response contains structured information suitable for visualization. It also applies to scenarios such as "Too much text to read", "Can it be more intuitive?", "Organize into a table".
Plan and build an RLM (Recursive Language Model) with predict-rlm. Interactively defines inputs, outputs, skills, and architecture from a goal, then implements the code. Use when the user wants to create a new RLM or explore whether one is feasible.
Phoenix Duskmoon UI component library for Elixir/Phoenix LiveView applications. Use when building UIs with `phoenix_duskmoon` — covers installation, CSS/JS setup, component usage patterns (dm_* prefix), slots, form inputs, icons, CSS art, and the v9 custom elements architecture. Trigger on: adding phoenix_duskmoon to a Phoenix project, using dm_* components, configuring themes, setting up hooks, or integrating @duskmoon-dev/core CSS design system.
