Build servers and clients for A2A, an open protocol that lets AI agents communicate across frameworks. Publish agent capabilities, exchange tasks and results, stream progress, and add notifications for workflows involving multiple agents.
Write TypeScript applications that read NEAR Protocol data, call contracts—programs on the blockchain—and send tokens. The skill also covers wallet connections, React integration, key management, transaction building, and testing in a local sandbox.
Build a disposable prototype to answer a specific design question. Use a shareable HTML demo to explore logic and state changes, or compare distinct UI variations on one route, then record the decision and retain the prototype separately.
Test one risky assumption through a prototype with an agreed deadline, hypothesis, and success signal. Record observations and the source revision, then return a keep, discard, or inconclusive verdict with the status of each artifact.
Create a single HTML file to review a product’s appearance or test a working flow. The skill follows the product’s design context and supports responsive layouts, keyboard interaction, form validation, and relevant interface states.
Master network protocol reverse engineering including packet analysis, protocol dissection, and custom protocol documentation. Use when analyzing network traffic, understanding proprietary protocols, or debugging network communication.

Build a self-contained local prototype at .turbo/prototypes/<slug>.html, drive it, and hand it to the user to settle unknowns that prose cannot answer. Use when the user asks to "prototype this", "build a prototype", "mock this up", "show me what it would look like", "let me try the interaction first", or when a decision waits on seeing a surface or using it firsthand.

Maintain an existing Proto UI Prototype or implement a governed Base or design-language component slice. Use for governed component behavior, anatomy, inheritance, exports, CLI registration, style projection, demos, or public preview work. Do not use to admit a new semantic subject or invent Base ownership from a component name.

Rapid UI prototyping — generates 3 visually distinct HTML/CSS components from a text prompt and serves them in a live browser gallery. Use when user runs /prototype, asks to "prototype a UI", "mock up a component", "generate HTML mockups", "create UI variations", "design exploration", "quick UI concept", or wants to see multiple visual approaches to a component. Also trigger when user says "show me different ways to build...", "explore different designs for...", or wants rapid visual exploration of a UI idea — even without saying "prototype" explicitly.

Use when working with Protocol Buffer (.proto) files, buf.yaml, buf.gen.yaml, or buf.lock. Covers proto design, buf CLI, gRPC/Connect services, protovalidate constraints, schema evolution, and troubleshooting lint/breaking errors.

Conversation patterns and interaction protocols for multi-agent systems. Covers request/response, pub/sub, blackboard, delegation chains, debate, critique, consensus, fan-out/fan-in, supervisor-worker, and peer negotiation. Deep analysis of AutoGen conversation patterns, CrewAI delegation, LangGraph state passing, and FIPA-ACL performatives. Teaches how to design what agents say to each other and in what order. Activate on: "agent conversation", "agent protocol", "multi-agent debate", "agent delegation", "supervisor worker pattern", "agent voting", "consensus protocol", "fan-out fan-in", "agent negotiation", "blackboard pattern", "agent dialogue", "conversation topology", "agent handoff". NOT for: wire format or serialization (use agent-interchange-formats), orchestration infrastructure (use agentic-infrastructure-2026), single agent behavior (use agentic-patterns).

Builds new UI prototypes and makes targeted changes to existing prototypes using consumer-owned context. Use when asked to build a prototype, mock up a UI, or add, change, refine or recreate part of an existing prototype. Do not use for unrelated tasks, routine commands, Git lifecycle actions, acknowledgements or infrastructure work.

在授权渗透测试中挖掘 JavaScript 原型污染（prototype pollution，服务端 Node.js 与客户端）。当目标把用户可控的键名递归合并进对象（merge/extend/set/clone、JSON body、query 解析）时使用——典型场景：用 `__proto__`/`constructor.prototype` 注入属性，污染全局原型，进而 DoS、改逻辑、配合 gadget 提权到 XSS/RCE。适用目标类型 Web / REST API（Node.js） / 前端。触发场景包括用户说"测下原型污染""这个 merge 能不能 __proto__""污染原型打 RCE/XSS""lodash/jquery 有没有污染点"。输出：污染点 + 可用 gadget 判定 + 反射证据的 finding（含 killed 记录）。

Build a throwaway prototype to answer a design question, as UI variations or a state-model walkthrough. Use when the user types /prototype, wants to sanity-check whether a state model or logic feels right, wants to explore what a UI should look like, or as the prototype step of the web design flow with brainstorm or grill before the final plan goes to plan-canvas (annotate the running prototype with the plan-canvas annotation tool).

Make Swift code easier to test by separating file access, networking, and external APIs behind small protocols. Replace those dependencies with mocks, controlled test substitutes, to check normal behavior and error handling with Swift Testing.
Access paid APIs using Machine Payments Protocol (MPP), a protocol for request payments. The skill checks payment requirements, selects a compatible wallet or client, submits payment, and helps inspect the API response and receipt.
Connect external services to Claude Code plugins through MCP, a protocol that exposes service functions as tools. Get guidance on server configuration, connection methods, authentication, tool permissions, and testing connections and tool calls.
Build a website prototype as a single HTML file using a supplied template and section layouts. Suitable for landing pages, pricing pages, and documentation indexes, with colors adapted to an existing design system.
Prototype a single-page website for SaaS, documentation, or knowledge products. Use warm off-white backgrounds, serif headings, fine dividers, generous spacing, and subtle motion to create a restrained layout with features and a signup or pricing section.
Creates web prototypes inspired by Swiss industrial print, using newsprint backgrounds, oversized black type, fine grid lines, and red accents. It suits editorial pages, agency portfolios, and manifesto sites with a precise, assertive visual style.
Build MCP servers, which let Claude call external tools and read data through a shared protocol. Follow Python or TypeScript examples to implement tools, connect services, configure Claude, and test server behavior.
Study Model Context Protocol (MCP), which connects AI applications with external tools, through guided lessons and exercises. Inspect requests and responses, practice implementation and security checks, and record progress alongside observed results.
