Install the PURISTA AI skill

PURISTA includes an AI assistant skill for architecture, service design, builders, runtime wiring, adapters, queues, subscriptions, AI Harness work, and implementation planning. Install it before asking an assistant to create or edit PURISTA services.

The skill is published from the PURISTA repository and can be installed with the skills CLI.

What it adds

The purista skill gives your assistant project-specific rules for:

  • starting from business capabilities and ownership boundaries
  • designing services, commands, subscriptions, streams, queues, workers, and agents
  • keeping builder definitions, runtime wiring, resources, stores, and adapters separated
  • using schemas and command contracts as reviewable boundaries
  • treating event bridges, queue bridges, stores, sandbox, and providers as runtime wiring
  • planning implementation work that stays aligned with PURISTA CLI conventions
