Turns Claude Code into a senior developer. Structured thinking, parallel agents, proper testing. Currently ranked #51 on GitHub globally. Install this one first — everything else builds on it.

Before you build anything, this forces Claude to think architecturally first — clarify the goal, map the risks, propose approaches, get your sign-off — before a single line of code. No more half-baked outputs.

Claude dispatches multiple fresh agents in parallel — one per independent task — each with a two-stage review (spec compliance, then code quality). This is what 10x speed actually looks like.

Every AI output sounds like AI. Em-dashes, throat-clearing openers, "certainly!", passive voice — this strips all of it. Scores your writing 1–10 across 5 dimensions and rewrites until it sounds human.

Describe what you're trying to do — Claude searches the entire skills ecosystem and finds the exact skill for the job. There are hundreds of verified skills at skills.sh. This is the one that unlocks all the others.
