Claude Skills by jgamaraalv

Multi-reviewer code-review orchestrator — dispatches the three quality reviewers (sr/sa/qa) and routes in domain specialists by what the diff touches. Use to review code, a diff/PR/branch/commit, run a quality gate, or check changes before committing.

Build, run, test, and drive the delivery-chain Claude Code plugin. Use when asked to run delivery-chain, run its tests, exercise the agent-memory hook sidecar, or verify the plugin's runtime works on this machine.

Default OpenSpec change workflow — scaffold a change through proposal → specs → design → tasks, apply it, then archive once merged. Use to start a change, write a proposal/spec/design/tasks, implement a tasks checklist, or archive a merged change.

Universal SQL query tuning across MySQL, PostgreSQL, SQL Server, and Oracle — execution plans, index strategy, pagination, batch operations. Use whenever a SQL query is slow or needs optimization.

Design scalable distributed systems — load balancing, caching, database scaling, message queues, capacity estimation. Use for "system design", "scale this", "high availability", "rate limiter", or choosing microservices vs monolith.

Design test strategies and test plans. Trigger with "how should we test", "test strategy for", "write tests for", "test plan", "what tests do we need", or when the user needs help with testing approaches, coverage, or test architecture.

Analyze, test, and improve skills, subagents, and their context layout — what lives HOT vs COLD, whether a grep/file index earns its cost, why a subagent won't read its references, cutting per-turn token bloat, and A/B testing a prompt or rule change.

UI/UX design intelligence — pick styles, color palettes, font pairings, layout & UX patterns across 10 stacks. Use when designing, building, reviewing, or restyling a web/mobile interface.

Animate React route/page changes, shared elements, and enter/exit/reorder with the View Transition API (`<ViewTransition>`); use for view transitions in React or Next.js.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs

Build real-time WebSocket/Socket.IO systems — auth at the handshake, rooms/namespaces, presence, reconnection, Redis pub/sub scaling. Use for bidirectional messaging, live updates, chat, or notifications.

Test WebSocket channels for CSWSH, smuggling, injection, and auth flaws (wsrepl, ws-harness, Burp). Use when an app uses real-time channels, chat, notifications, or WS-backed APIs.
