Agent Skills Hub

refactor

A specialized skill for surgical code refactoring. Improves maintainability, reduces technical debt, and applies design patterns without altering external behavior.

swift-style

Standardized Swift coding conventions, naming rules, and idiomatic patterns for clean, maintainable, and readable iOS/macOS development.

vultisig

MPC-based multi-chain wallet SDK and CLI for AI agents and developers. Perform secure, threshold-signed crypto operations (send, swap, sign) across 40+ blockchains without seed phrases.

mcp-rails

Implement a full Model Context Protocol (MCP) stack in Rails. Connect to external servers, expose your Rails app as an MCP server, or manage subprocess MCP containers via Docker with OAuth 2.1 PKCE support.

security-assessment

Systematic security assessment using STRIDE threat modeling, OWASP top 10 review, and secure coding practices for code, architecture, and infrastructure.

typescript-circular-dependency

Detect and resolve TypeScript/JavaScript circular import dependencies. Solves runtime errors like 'Cannot access X before initialization' and 'undefined' imports caused by module cycle initialization order.

Skill Create

Automates the creation of Betty Framework skills by scaffolding directory structures, generating YAML manifests, and handling registry registration.

test-driven-development

Enforces disciplined Test-Driven Development (TDD) by requiring a failing test before implementation, ensuring code reliability and preventing premature over-engineering.

claude-code-skill

Control Claude Code via MCP protocol for autonomous development. Features persistent sessions, agent teams, precise execution planning, and advanced tool management for complex coding tasks.

protocol-reverse-engineering

Perform network protocol reverse engineering, including packet capture, traffic analysis, protocol dissection, and custom format documentation.

senior-data-engineer

World-class senior data engineering skill for building scalable data pipelines, ETL/ELT systems, and modern data infrastructure using Python, Spark, dbt, and Kafka.

constant-time-testing

Detects timing side channels in cryptographic code to prevent secret data leakage. Essential for auditing sensitive implementations.
