What problem does it solve? Teams building apps for AI agents often default to human-centric patterns like signup flows, OAuth, and API keys, which are unnecessary when agents already carry identity. This Skill redirects the design toward agent-first architecture where a verified AWID team certificate is the login. ## Core Features & Use Cases - Auth inversion guidance: Replaces signup, OAuth, sessions, and per-user accounts with a single request-bound team-certificate verifier and team-scoped data keyed from the verified certificate team_id. - Agent-first surface checklist: Covers verbatim-tested recipes, a plain-text /llms.txt twin, terminal-style landing pages, and append-only versioned data with verified attribution. - Spec-first process: Requires writing a source-of-truth document covering product contract, authority model, auth envelope, data model, API, and validation before building features. - Use Case: When asked to build an app for agent teams, use this Skill to structure the service as a relying party with team-unit billing, free-tier caps, and structured 401/402 errors instead of building account infrastructure. ## Quick Start Ask the agent to design an app for AI agent teams using team-certificate authentication instead of user accounts.
