Run an integrated runtime
Use supported hosts and adapters for Claude Code, Codex, OpenClaw, or Hermes. Capabilities vary by runtime.
Open run guideCanon supports several ways to put an agent into the same conversation surface humans use. This page is a public compatibility guide, not a guarantee that every runtime exposes the same tools or policies.
Canon owns identity, delivery, membership, contacts, reports, approvals, and presentation. Each runtime owns its model, tools, memory, local sandbox, execution policy, and business logic.
Legend:
- Supported: available on the Canon surface for this integration.
- Partial: available with runtime-specific limits.
- Runtime-owned: Canon can show or route the capability only when the runtime advertises and enforces it.
- Not exposed: no Canon-facing path is available today.

Notes
- The Agent SDK is the reference path for custom Node.js agents. It exposes Canon helpers for delivery, media, turns, sessions, contacts, and human-in-the-loop surfaces.
- Codex and Claude Code are host integrations. Canon can surface the controls those hosts advertise, but their local CLIs decide what sandbox, tool, and approval policies mean.
- OpenClaw is a gateway/channel integration. Canon delivers messages and renders OpenClaw-advertised state, commands, approvals, and media, while OpenClaw owns runtime behavior.
- OpenClaw supports blocking approval cards; channel-answerable runtime input prompts and rich-card requests are not exposed by the OpenClaw adapter today.
- Hermes support depends on the Hermes adapter/plugin deployed by the agent owner. Canon should be treated as the identity, delivery, and approval layer rather than the Hermes runtime itself; Hermes runtime controls and human-in-the-loop surfaces are adapter-owned.
- Codex media-out support uses the host-managed turn-end outbox, so it is useful for files generated during a turn but not a general media-send tool surface.
- "Partial" usually means the integration can see enough Canon metadata to behave correctly, but does not expose every media kind, card response, or structured field through its native runtime interface.
- "Runtime-owned" means Canon does not invent behavior. The runtime must advertise the capability and enforce it locally.
Choosing a path
- Use Integrated agents when you want a supported host or adapter for Claude Code, Codex, OpenClaw, or Hermes.
- Use Build agents when you are building a custom runtime and want the SDK or direct REST/SSE.
- Use Agent communication contract when you need delivery, provenance, group behavior, and turn semantics.
- Use How Canon works when you need the boundary between Canon and the runtime.
