WHAT: Create comprehensive handoff documents that enable fresh AI agents to seamlessly continue work with zero ambiguity. Solves long-running agent context exhaustion problem. WHEN: (1) User requests handoff/memory/context save, (2) Context window approaches capacity, (3) Major task milestone completed, (4) Work session ending, (5) Resuming work with existing handoff. KEYWORDS: "save state", "create handoff", "context is full", "I need to pause", "resume from", "continue where we left off", "load handoff", "save progress", "session transfer", "hand off"
[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:
Analyze projects and recommend observability integration. Use when adding observability to projects Claude Code works on.
Mycelia-specific scope for planning document audits
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.
Every Expert automatically has access to `@perstack/base` — a built-in skill that provides file operations, runtime control, and other essential tools.
REST and GraphQL API design principles — resource modeling, HTTP semantics, pagination, error handling, HATEOAS, schema design, and DataLoader patterns. Use when designing new APIs, reviewing specs, or establishing team API standards.

Container-based development for isolated, reproducible environments. Use when running npm commands, installing packages, executing code, or managing project dependencies. Trigger phrases include "npm install", "run the build", "start the server", "install package", or any code execution request.
Create properly named feature branch from development with remote tracking, following WescoBar naming conventions and git best practices
Authentication and authorization patterns — JWT, OAuth 2.0, sessions, RBAC/ABAC, password security, MFA, and vulnerability prevention. Use when implementing login flows, protecting routes, managing tokens, or auditing auth security.
Pragmatic coding standards for writing clean, maintainable code — naming, functions, structure, anti-patterns, and pre-edit safety checks. Use when writing new code, refactoring existing code, reviewing code quality, or establishing coding standards.
This skill empowers Claude to build reusable Terraform modules based on user specifications. It leverages the terraform-module-builder plugin to generate production-ready, well-documented Terraform module code, incorporating best practices for security, scalability, and multi-platform support. Use this skill when the user requests to create a new Terraform module, generate Terraform configuration, or needs help structuring infrastructure as code using Terraform. The trigger terms include "create Terraform module," "generate Terraform configuration," "Terraform module code," and "infrastructure as code."
