Blockchain

Enables token-efficient structured development via /serena command. Use for component development, API implementation, system design, test creation, bug fixes, and optimization. Available for Claude Code and all Agents.

Generate a reference architecture specification from analyzed frameworks. Use when (1) designing a new agent framework based on prior art, (2) defining core primitives (Message, State, Tool types), (3) specifying interface protocols, (4) creating execution loop pseudocode, or (5) producing architecture diagrams and implementation roadmaps.

Generate cryptographic proof packets for verification.

Extracts and documents design tokens (colors, typography, spacing, shadows, etc.) from Figma designs. Updates the "デザイントークン" section in screen spec.md.

Meta-skill for AI-User collaboration within the BL1NK Monorepo. Defines rules for file creation, redundancy management, and systematic workflow execution based on historical interaction patterns.

Defining, loading, and managing relationships between Ash resources

Token-efficient documentation search using Serena Document Index. 90%+ token savings vs reading full files. Use BEFORE reading README.md or docs/ files. Triggers on architecture questions, pattern lookups, and project-specific documentation needs.

Get expert perspective on a problem by synthesizing an ideal consultant. Use when: (1) asked to consult expert or get specialist input, (2) problem involves specialized domain, (3) analyzing from expert viewpoint, (4) right expertise is not predefined.

Apply when building or auditing UI. Enforces design tokens, Shadcn-first patterns, alignment rules, and the "fun but functional" aesthetic for Recipe App components.

Transform vague or incomplete user stories into sprint-ready stories with clear acceptance criteria, test scenarios, and technical guidance. This skill should be used before sprint commitment for definition of ready check.

Expert knowledge for runtime validation in TypeScript using ArkType, a syntax-first validation library with TypeScript-like definitions, JIT compilation for 10x-100x performance over Zod, native recursion support, morphs for data transformation, and Standard Schema compatibility

Define functors from domain to target categories. Uses targets.yaml todetermine which functors to create. Maps domain objects and morphismsto target representations. Use when: mapping domain to API, persistence,events; formalizing structural transformations.

Define what to build at what fidelity to learn what you need without over-investing. Use before starting any prototype.

Documents all UI state variations (default, empty, error, loading, success) from Figma designs. Use when defining complete UI specifications before implementation.

Zod schema validation and React Hook Form integration for TypeScript frontends. This skill should be used when creating forms, defining API schemas, validating form data, implementing type-safe validation, using ZodResolver with React Hook Form, or migrating legacy forms to the Zod + React Hook Form pattern.

This skill should be used when the user asks to "identify epics", "break down vision into epics", "find major features", "discover capability areas", "decompose vision", "group requirements into themes", "define high-level features", "what epics do I need", "turn vision into work items", or "split project into epics". Provides methodology for deriving epics from a vision statement using user journey mapping, capability decomposition, and stakeholder analysis.

Distinguish user wants from underlying needs to guide solution design. Use when stakeholders make feature requests or during Define phase.

Provides GraphQL API schema design and implementation expertise. Ensures proper type definitions, query/mutation patterns, pagination strategies, and error handling standards. Specializes in schema-first design, resolver implementation, DataLoader for N+1 prevention, subscription patterns, and federation architecture. Implements Relay cursor connections and Apollo best practices.Use when: designing GraphQL schemas, defining types and interfaces, implementing queries and mutations, creating resolvers, designing pagination with connections and edges, solving N+1 query problems with DataLoader, implementing subscriptions for real-time updates, handling errors and nullability, setting up GraphQL federation, or integrating with Apollo Server/Client or other GraphQL libraries.

Technical analysis with 29+ indicators (BB, Ichimoku, RSI, MACD). Generates 7-tier trading signals with divergence detection, volume confirmation, and squeeze alerts for crypto and stocks.

Test smart contracts comprehensively using Hardhat and Foundry with unit tests, integration tests, and mainnet forking. Use when testing Solidity contracts, setting up blockchain test suites, or validating DeFi protocols.
