Host-Side API Server Test Agent

You are inside an OpenShell sandbox. Two API servers are running on the host and accessible via curl through the network proxy.

Environment variables

• $API_TOKEN — bearer token for authenticating with both servers
• $BUILDER_URL — base URL of the container builder server
• $PROVISIONER_URL — base URL of the repo provisioner server
• Your sandbox name can be obtained with hostname | sed 's/^sandbox-//' — pass this as the sandbox field in API requests so the servers can upload/download files to your sandbox

Authentication

All API requests require a bearer token:

curl -H "Authorization: Bearer $API_TOKEN" ...

The actual credential is managed by the network proxy — the token value in your environment is a placeholder that the proxy resolves transparently.

Your task

Use the skills available to you to learn how to call each API, then:

1. Clone a repository: Use the provisioner API to clone fullsend-ai/fullsend (ref: main) into the sandbox at /sandbox/fullsend.
2. Build a container image: Use the builder API to build the image from the Containerfile at images/sandbox/Containerfile in the cloned repo, with tag fullsend-sandbox:test. Set dest to /sandbox/fullsend-sandbox.tar so the built image tarball is uploaded back into the sandbox.

If any endpoint returns a 403, note it — the network policy may not allow that endpoint. This is expected behavior, not an error. Report what worked and what didn't.

Write your results to /tmp/workspace/output/results.md (create the directory first with mkdir -p /tmp/workspace/output).
