Comprehensive guide to the Compact programming language for writing privacy-preserving smart contracts on Midnight Network. Use when users need to write Compact smart contracts with zero-knowledge proofs, understand Compact syntax and language features, implement ZK circuit patterns and optimizations, generate contract boilerplate and project scaffolding, learn best practices for secure contract development, access Compact standard library functions, and compile and test Compact contracts.
effect-ts
by teeverc
"Effect-TS (Effect) guidance for TypeScript. Use when building, refactoring, reviewing, or explaining Effect code, especially for: typed error modeling (expected errors vs defects), Context/Layer/Effect.Service dependency wiring, Scope/resource lifecycles, runtime execution boundaries, schema-based decoding, concurrency/scheduling/streams, @effect/platform APIs, Effect AI workflows, and Promise/async migration."
solid-hunter-go
by skyosev
Audit Go code for design principle violations — god packages, rigid extension points, broken interface contracts, fat interfaces, and concrete dependency chains. Adapted from SOLID for Go's composition-over-inheritance model. Use when: reviewing package structure, preparing for extension with new variants, reducing coupling between packages, or improving testability.
stratum-v1
by b-open-io
This skill should be used when the user asks to "implement Stratum v1", "mining pool protocol", "JSON-RPC mining", "pool-miner communication", "mining.subscribe", or needs to build Stratum v1 mining infrastructure.
cortex-classify-notebook
by Snowflake-Labs
Deploy the Cortex CLASSIFY_TEXT tutorial notebook to the user's Snowflake account and provide a link to open it in Snowsight. Use when user wants to learn text classification through a Jupyter notebook experience.
type-hunter-ts
by skyosev
Audit TypeScript type definitions for design debt — duplicated shapes, missing derivations, over-engineered generics, under-constrained type parameters, reinvented utility types, and disorganized type architecture. Type structure and maintainability, not type enforcement. Use when: reviewing type definitions for maintainability, reducing type duplication, simplifying over-engineered type-level logic, or reorganizing type architecture after growth.
write-unit-tests
by EYH0602
Writing unit and integration tests for the tldraw SDK. Use when creating new tests, adding test coverage, or fixing failing tests in packages/editor or packages/tldraw. Covers Vitest patterns, TestEditor usage, and test file organization.
read-repo-references
by EYH0602
Learn from reference materials and prior art in the .references/ directory
typescript-architect
by DmitriyYukhanov
Creates high-level TypeScript architecture with interfaces, test stubs, and module structure. Use when designing TypeScript/JavaScript projects or features.
AIRS & Appropriate Reliance Research
by fabioc-aloha
"Domain knowledge for AI adoption measurement, psychometric instrument development, and appropriate reliance research"
typescript-testing
by DmitriyYukhanov
TypeScript testing patterns with Jest/Vitest including unit tests, integration tests, mocking strategies, and coverage. Use when writing or running TypeScript tests.
mcp-server
by Cam10001110101
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
UI Design
by constellos
This skill should be used when the user asks to "create a component", "build static UI", "design with TypeScript", "use compound components", "implement contract-first UI", "create React component", "build with Shadcn", or mentions TypeScript interfaces for components, compound component patterns, or Server Components. Provides contract-first static UI methodology with compound components.
key-derivation
by b-open-io
This skill should be used when the user asks to "derive keys", "use Type42", "use BRC-42", "derive child keys", "use BIP32", "use HD keys", "create mnemonic", "convert mnemonic to key", "derive BAP identity keys", "derive encryption keys", or mentions key derivation, hierarchical deterministic wallets, invoice numbers, or child key generation on BSV.
python-coder
by DmitriyYukhanov
Implements Python code following PEP 8, type hints, and project conventions. Use when implementing features designed by python-architect.
security-hunter-go
by skyosev
Audit Go code for security vulnerabilities — hardcoded secrets, injection risks (SQL, command, template, path), missing input validation at trust boundaries, insecure defaults, auth gaps, sensitive data exposure, unsafe package usage, and weak crypto. Use when: reviewing Go code before deployment, auditing trust boundaries, preparing for a security review, onboarding third-party integrations, or hardening an application.
simplicity-hunter-ts
by skyosev
Audit TypeScript code for unnecessary structural complexity — duplication, avoidable abstractions, dead logic paths, flag-heavy APIs, deep nesting, and mixed concerns. Recommends the simplest shape that preserves intended behavior. Use when: reviewing TypeScript code for over-engineering, reducing complexity after prototyping, enforcing reuse over addition, or simplifying before a refactor.
solid-hunter-ts
by skyosev
Audit TypeScript class and interface design for SOLID violations — god classes, rigid extension points, broken substitutability, fat interfaces, and concrete dependency chains. Focuses on responsibility assignment and abstraction fitness. Use when: reviewing class hierarchies, preparing for extension with new variants, reducing coupling between services, or improving testability of class-heavy code.

client-delivery
by dtsong
"Use this skill when managing a consulting data cleaning engagement. Covers engagement setup, schema profiling, security tier selection, project scaffolding, deliverable generation, and client handoff. Common phrases: \"set up a cleaning project\", \"profile this schema\", \"data cleaning engagement\", \"generate deliverables\", \"client handoff\". Do NOT use for writing dbt models (use dbt-transforms), DuckDB queries (use duckdb), or pipeline orchestration (use data-pipelines)."
