Skills that compound

Start with our skills.
They get sharper every week.

You don’t configure a thing. Install the CLI and you ship with a full spec-to-verify workflow — then ZeroShot watches how your team actually works, identifies the patterns you keep repeating, and turns them into new skills tuned to you.

Skills that learn

Your junior inherits
your senior’s wins.

Every PR review your team writes, every steering correction, every “actually, we do it this way” becomes a skill the next person uses. The agent shows up already knowing the conventions your seniors settled on — so nobody spends tokens learning them the hard way again.

  • → Conventions encoded once, applied by every agent
  • → Skills update from your real review patterns, not a template
  • → We open a weekly PR suggesting new skills from your sessions

Each correction your team makes once is in the skill the next person uses.
