DevOps

Design system architectures with focus on scalability, maintainability, and user value. Create comprehensive architectural documentation including technology decisions, API design, data architecture, and security. Use when designing new systems, making technology choices, or planning system migrations.

Observability patterns for metrics, logs, and traces. Use when implementing monitoring, setting up Prometheus/Grafana, configuring logging pipelines, implementing distributed tracing, or designing alerting systems.

Product Owner & App Journey Architect role skill. Use when Claude needs to act as a seasoned product owner who translates business goals into clear, actionable product requirements; identifies gaps, ambiguities, and hidden assumptions; designs and documents user journeys, system flows, and state diagrams using Mermaid; reviews high-level designs for completeness and feasibility; uncovers edge cases, failure scenarios, and error-handling strategies; and validates specifications are build-ready. Triggered by requests to review product specs, design user journeys, create system flows, challenge requirements clarity, identify design gaps, or architect application flows.

Review implementation fidelity against specifications by comparing actual code to spec requirements. Identifies deviations, assesses impact, and generates compliance reports for tasks, phases, or entire specs.

Systematic decision tree and epic generation through Socratic discovery

Manages project-specific commands for development, testing, and deployment. Use when needing to run project commands or when setting up commands for a new project.

Create specialized Claude Code agents on-the-fly. Guides through agent definition file creation with proper frontmatter, effective prompts, and tool scoping. USE WHEN user says 'create agent', 'new subagent', 'make an agent for', 'build agent', 'spawn agent', or wants to define custom agents for specific tasks.

Kubernetes deployment patterns and best practices. Use when creating Kubernetes manifests, Helm charts, configuring pods, services, deployments, or troubleshooting K8s clusters.

This skill should be used when users need help with htmx development, including implementing AJAX interactions, understanding htmx attributes (hx-get, hx-post, hx-swap, hx-target, hx-trigger), debugging htmx behavior, building hypermedia-driven applications, or following htmx best practices. Use when users ask about htmx patterns, server-side HTML responses, or transitioning from SPA frameworks to htmx. (user)

Analyzes codebases to generate comprehensive documentation including structure, languages, frameworks, dependencies, design patterns, and technical debt. Use when user says "analyze repository", "understand codebase", "document project", or when exploring unfamiliar code.

GitHub Actions workflows, quality gates, and release automation

Master backend API development with Node.js, Python, PHP, Java, C#, GraphQL, REST APIs, databases, and microservices. Learn server-side architecture, authentication, scalability, and production deployment.

Query the ragsharp code graph for declarations, references, callers, callees, dependencies, and line-number evidence. Triggers: find usages, where defined, callers, callees, dependency path, project deps, type hierarchy, line numbers, evidence.

Track issues and dependencies with beads (bd). Use when work spans multiple sessions, has blockers/dependencies, or needs to survive conversation compaction. Triggers - "create task", "what's ready", "show task", "track this", "what's blocking", "update status".

Sync workflows for Workbench CLI. Use when aligning local work items with GitHub issues, creating branches, or reconciling doc backlinks.

Quick access to up-to-date library documentation using MCP. Use this skill when you need to reference official documentation for libraries, frameworks, or APIs. Leverages the context7 MCP server to fetch current docs for React, Next.js, Vue, MongoDB, Supabase, and hundreds of other libraries. Complements the documentation-maintainer agent.

Industry-specific automation playbooks. Use when targeting a specific vertical for workflow recommendations, pain point mapping, and bundled offerings. Covers e-commerce, professional services, logistics, legal/finance, global trade (export, import, re-export), manufacturing, distribution, and construction.

Document architectural decisions with context and consequences.

Go idioms, style guide, and best practices with YAGNI/KISS principles. Use when writing or reviewing Go code.
