devx-qa
Deeply analyze codebase architecture to generate ASCII state machine graphs and sequence diagrams, audit React apps for anti-patterns like useEffect misuse with scored gap analysis and prioritized fixes, and evaluate Claude plugin skills against Anthropic best practices.

Component Details
Skills (3)
Analyzes project architecture and generates ASCII state machine and sequence diagrams. Use when the user asks to explain a project, analyze architecture, trace an entrypoint, show a state machine, or generate a sequence diagram.
Audits React codebases for anti-patterns (useEffect misuse, missing cleanup, stale closures, derived-state-in-effects, memory leaks) and produces a scored gap analysis table with severity ratings. Applies prioritized fixes on request. Triggers on: audit react code, fix react anti-patterns, review react hooks, scan for react issues, check useEffect cleanup, fix memory leaks in react.
Evaluate and improve a plugin's skills by applying Anthropic's skill authoring best practices. Triggers when the user asks to fix, improve, or review skills for a specific plugin or agent team.

Why These Plugins
Most plugins in the wild are vibe-coded in an afternoon and never touched again.
These are different.
Every command in this marketplace comes from real, daily usage — refined over months, not as experiments, but as core tools in an actual development workflow.
- Curated — Only what survives daily use makes it here
- Updated — Continuously improved based on friction points
- Tested — Used hundreds of times across real projects
- Minimal — No bloat, no clever abstractions, just what works

Philosophy
Battle-tested — Every command exists because it solved a real problem, repeatedly.
Opinionated — Conventional commits. Proper PR descriptions. ASCII diagrams. Decisions are made so you don't waste time configuring.
Honest — If something doesn't work well, it gets fixed or removed.
Minimal — No dependencies. No build steps. Just markdown that Claude understands.
