Nodes: pairing, capabilities (canvas/camera), and the CLI helpers for screenshots + clips	Pairing iOS/Android nodes to a gateway Using node canvas/camera for agent context Adding new node commands or CLI helpers

Nodes

A node is a companion device (iOS/Android today) that connects to the Gateway over the Bridge and exposes a small command surface (e.g. canvas.*, camera.*) via node.invoke.

Pairing + status

Pairing is gateway-owned and approval-based. See docs/gateway/pairing.md for the full flow.

Quick CLI:

clawdis nodes pending
clawdis nodes approve <requestId>
clawdis nodes reject <requestId>
clawdis nodes status
clawdis nodes describe --node <idOrNameOrIp>

Invoking commands

Low-level (raw RPC):

clawdis nodes invoke --node <idOrNameOrIp> --command canvas.eval --params '{"javaScript":"location.href"}'

Higher-level helpers exist for the common “give the agent a MEDIA attachment” workflows.

Screenshots (canvas snapshots)

If the node is showing the Canvas (WebView), canvas.snapshot returns { format, base64 }.

CLI helper (writes to a temp file and prints MEDIA:<path>):

clawdis nodes canvas snapshot --node <idOrNameOrIp> --format png
clawdis nodes canvas snapshot --node <idOrNameOrIp> --format jpg --max-width 1200 --quality 0.9

Photos + videos (node camera)

Photos (jpg):

clawdis nodes camera snap --node <idOrNameOrIp>            # default: both facings (2 MEDIA lines)
clawdis nodes camera snap --node <idOrNameOrIp> --facing front

Video clips (mp4):

clawdis nodes camera clip --node <idOrNameOrIp> --duration 10s
clawdis nodes camera clip --node <idOrNameOrIp> --duration 3000 --no-audio

Notes:

• The node must be foregrounded for canvas.* and camera.* (background calls return NODE_BACKGROUND_UNAVAILABLE).
• Clip duration is clamped (currently <= 60s) to avoid oversized base64 payloads.
• Android will prompt for CAMERA/RECORD_AUDIO permissions when possible; denied permissions fail with *_PERMISSION_REQUIRED.
