The Capability Schema (capability.v1.json) is the open, versioned schema for describing what an agent can do. A manifest names the capability, its inputs and outputs, any side effects, the data classes it touches, the guardrails it enforces, the SLAs it commits to and the pricing model — in a single machine-readable file.
It is published under a permissive license and is the substrate for Discovery search and trading-desk routing. Validate any manifest in the browser (no server round-trip) at standards/capability-schema.html.
