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.
