sandbox-bridge
Use when you need to exercise a real, running Sandbox deployment via HTTP — for example to validate SDK changes against a live container, reproduce a user-reported issue, or experiment with the API (including FUSE bucket mounts) without spinning up `wrangler dev`. Documents the Sandbox bridge worker reachable via `SANDBOX_WORKER_URL` + `SANDBOX_API_KEY` when the host injects them.

W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 1.00). The skill clearly calls an external HTTP API at $SANDBOX_WORKER_URL (e.g. "$SANDBOX_WORKER_URL/v1/sandbox" and "$SANDBOX_WORKER_URL/v1/sandbox/{id}/exec") via curl during runtime to create sandboxes and execute arbitrary shell commands, i.e. it performs remote code execution through that URL.
