17 BYOK agents, one skill protocol.

How adapters plug in

Every adapter is a thin shim between the agent native message format and Open Design skill protocol. Adding a new adapter is a single file — no fork required.

Tier 1 — first-party tested

Battle-tested daily by the Open Design maintainers. Stream-JSON IPC where supported, full AskUserQuestion mid-turn, skill-aware system prompts.

What BYOK means here

BYOK ("bring your own key") in Open Design keeps credentials and spend on your side:

• Credentials live in .od/media-config.json or your shell env.
• API calls go from your machine straight to your provider.
• Switching providers is a key swap, not a re-onboard.
• API spend bills to your account on each provider.
