SLURM and HPC guidance for Mycelia benchmarks and large-scale analysis

Consolidate and refine extracted skills and docs from multiple projects into unified, project-agnostic patterns. Use when staging folder has content from multiple projects ready for consolidation. Triggers on "refine staged content", "consolidate staged skills", "process staging", "merge extracted patterns".

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Opinionated guide for building dApps on Arbitrum using Stylus (Rust) and/or Solidity. Covers local devnode setup, contract development, testing, deployment, and React frontend integration with viem. Use when starting a new Arbitrum project, writing Stylus or Solidity contracts, deploying to Arbitrum, or building a frontend that interacts with Arbitrum contracts.

Every Expert automatically has access to `@perstack/base` — a built-in skill that provides file operations, runtime control, and other essential tools.

Error handling patterns across languages and layers — operational vs programmer errors, retry strategies, circuit breakers, error boundaries, HTTP responses, graceful degradation, and structured logging. Use when designing error strategies, building resilient APIs, or reviewing error management.

Write specification documents for features using specification-driven development practices, including requirements with user stories, architecture design documents with correctness properties, and implementation plans with task breakdowns. Use when planning a new feature, designing system architecture, creating implementation roadmaps, or documenting technical specifications.

Create distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Focuses on creative direction and memorable design choices.

This skill enables Claude to conduct a security-focused code review using the security-agent plugin. It analyzes code for potential vulnerabilities like SQL injection, XSS, authentication flaws, and insecure dependencies. Claude uses this skill when the user explicitly requests a security audit, asks for a code review with a focus on security, or mentions security concerns related to code. The security-agent plugin then provides structured security findings with severity ratings, code locations, impact assessments, and remediation guidance.

Mycelia-specific scope for planning document audits

WHAT: Guide for creating effective AI agent skills - modular packages that extend Claude's capabilities with specialized knowledge, workflows, and tools. WHEN: User wants to create, write, author, or update a skill. User asks about skill structure, SKILL.md format, or how to package domain knowledge for AI agents. KEYWORDS: "create a skill", "make a skill", "new skill", "skill template", "SKILL.md", "agent skill", "write a skill", "skill structure", "package a skill"

Analyze projects and recommend observability integration. Use when adding observability to projects Claude Code works on.

[Alexa](https://developer.amazon.com/alexa) is Amazon's cloud-based voice service. Most people are familiar with the service through using an [Amazon Echo or Echo dot](https://developer.amazon.com/alexa/echo) but the service can also be integrated in to custom internet-connected devices like this talking robotic fish:

Master advanced prompt engineering techniques to maximize LLM performance, reliability, and controllability in production. Use when optimizing prompts, improving LLM outputs, designing production prompt templates, or building AI-powered features.

Searchable UI/UX design databases: 50+ styles, 97 palettes, 57 font pairings, 99 UX rules, 25 chart types. CLI generates design systems from natural language. Data-driven complement to ui-design.

Comprehensive UI design skill covering fundamentals, patterns, and anti-patterns. Layout, typography, color, spacing, accessibility, motion, and component design. Use when building any web interface, reviewing design quality, or creating distinctive UIs.

Develop typescript frontend and/or backend
