JustHandled Labs builds small, sharp skills for AI coding agents. One skill, one repeatable task, done properly, no theatrical complexity.

This channel is the demo shelf: short screencasts of each skill actually running on real input, not mockups. Cost-leak linters, build sanity checks, model-migration checkers, AI disclosure and compliance linters, pre-launch checks for non-technical founders, and the agent-native plumbing like AGENTS.md, llms.txt, and tool schemas.

Made for people shipping with Claude Code, Cursor, Codex CLI, Windsurf, and Cline. Especially the ones moving fast enough to want a second set of eyes that never gets tired.

Get the skills on Agensi and Gumroad. More at justhandledlabs.com.
