Software architecture patterns and best practices

This skill guides creating autonomous agents for Claude Code plugins using markdown files with YAML frontmatter. Use when building new agents, designing agent system prompts, or configuring agent behavior.

Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.

This skill should be used when the user asks to "implement a feature", "add functionality", "build a new feature", "fix a non-trivial bug", or needs a structured development workflow. Orchestrates 7-phase workflow with user approval gates and TDD enforcement.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations.

Resolves ambiguous organism names to precise NCBI taxonomy IDs and scientific names, then recommends appropriate IWC (Intergalactic Workflow Commission) Galaxy workflows for analysis. Use this skill when users provide common names (like "malaria parasite", "E. coli", "mouse"), abbreviated names, or when you need to convert any organism reference to an exact scientific name for API queries. This skill handles disambiguation through conversation, validates taxonomy IDs via NCBI Taxonomy API, provides ENA FASTQ search capabilities, and ALWAYS recommends existing IWC workflows rather than producing custom scripts or analysis steps.

This skill provides comprehensive backend REST API integration for Asleep sleep tracking platform. Use this skill when building server-side applications, API proxies for mobile apps, webhook event handlers, cross-platform backends (React Native, Flutter), analytics dashboards, or multi-tenant sleep tracking systems. Covers authentication, user management, session retrieval, statistics, webhook integration, and production-ready patterns with code examples in Python, Node.js, and curl.

Profile and optimize Python code using cProfile, memory profilers, and performance best practices. Use when debugging slow Python code, optimizing bottlenecks, or improving application performance.

Master software architecture, system design, design patterns, distributed systems, and technical leadership. Learn to architect scalable, reliable, and maintainable systems.

Diagnose and fix Deptrac architectural violations automatically. Use when Deptrac reports dependency violations, layers are incorrectly coupled, or when refactoring code to respect hexagonal architecture boundaries. Never modifies deptrac.yaml - always fixes the code to match the architecture.

Use when creating, improving, or troubleshooting Claude Code subagents. Expert guidance on agent design, system prompts, tool access, model selection, and best practices for building specialized AI assistants.

Detect and resolve incoherence in documentation, code, specs vs implementation. Includes reconciliation phase for applying user-provided resolutions.

Format Rust and Meson code using justfile tasks (just fmt-rs, just fmt-meson). Use when editing .rs or meson files, mentions formatting, code style, rustfmt, cleanup, or before commits/PRs. Ensures consistent code style across the codebase.

This skill should be used when users need to create Jira tickets for the RD (Research & Development) project. It supports creating features, bugs, and tasks with proper field mapping including assignee, team, sprint, and state. The skill uses Jira CLI commands and provides templates for different ticket types.
