Cloud Agents With Cloud Agents, spawn asynchronous agents that edit and run code in a remote Android Studio environment with a built-in Android emulator. View their status, send follow-ups, or take over anytime.
Cloud Agents are only available on Teams and Enterprise plans.

How to Use

You can launch Cloud Agents in two ways:
  • Cloud Agents API — programmatically create and manage agents via REST API
  • GitHub — use the /firebender slash command in any issue or pull request

GitHub

Once the Firebender GitHub App is installed, type /firebender in any issue or pull request comment to launch a Cloud Agent.
/firebender

Fix the crash when opening the settings screen.
The agent will clone your repo, work on the task, and push changes to a new branch. For issues, it automatically creates a pull request when finished. For PRs, it commits directly to the existing branch.

Modes

You can specify an agent mode using mode=:
/firebender mode=mobile_use

Test the login flow and verify the UI renders correctly.
The default mode is write. To use a different mode, pass mode=<mode> — for example, mode=mobile_use. See Agent Modes for all available modes.

Follow-ups

If an agent is already running on an issue or PR, commenting /firebender again sends a follow-up instruction to the existing agent instead of creating a new one. If the agent has finished, a continuation agent is created on the same branch.

Setup

Cloud Agents run on an isolated environment with Android Studio and an Android emulator. Agents have internet access and can install packages. The setup process involves:
  1. Connect GitHub: Link your GitHub account in your Cloud Agent settings
  2. Environment Configuration: Optionally add a .firebender/environment.json to your repo to customize the JDK, setup scripts, and run configuration

GitHub Connection

Cloud Agents clone your repo from GitHub and work on a separate branch, pushing to your repo for easy handoff. You will need read-write privileges to your repo (and any dependent repos or submodules). Grant access through the Firebender GitHub App in your Cloud Agent settings.

Environment Configuration

Cloud Agents load an optional configuration file from your repository to customize the sandbox environment. File location: .firebender/environment.json (repo root)
{
  "jdk": { "version": "17.0.11-tem" },
  "setup": { "script": "scripts/firebender-setup.sh" },
  "run": { "configName": "app.application" }
}
FieldTypeDescription
jdk.versionstringSDKMAN JDK identifier (e.g. 17.0.11-tem). If omitted, the default JDK in the base image is used.
setup.scriptstringRepo-relative path to a setup script that runs after clone and before Android Studio starts. Use this to install extra dependencies or configure the environment.
run.configNamestringAndroid Studio run configuration to execute before the agent starts. Use this to specify which app the agent launches on the emulator. Only applies to mobile_use and debug_auto modes.

Environment Variables and Secrets

Cloud Agents need access to your environment variables and secrets (like API keys, signing configs, etc.) to run properly. Configure secrets in your Cloud Agent settings:
  • Add your secrets as key-value pairs
  • All secrets are encrypted at rest
  • Available to Cloud Agents as environment variables
  • Shared across all Cloud Agents for your workspace/team

Agent Modes

ModeDescription
writeDefault mode. The agent reads and writes code to complete the task.
readThe agent can read and analyze code but does not make changes.
mobile_usewrite mode with a remote Android emulator. The agent can interact with and test the running app. Records and uploads the emulator screen.
debug_autoLike mobile_use, but the agent will also set breakpoints, test hypotheses, and use the emulator to fix bugs. Best for automated debugging workflows.
In mobile_use and debug_auto modes, the agent can tap, swipe, type, and take screenshots of your running app on the emulator. The emulator screen recording is uploaded and available through the Cloud Agents API.

Verifying and Testing Changes

Before merging changes made by Cloud Agents, you’ll want to verify they work correctly.

Testing in the Cloud Instance

After a Cloud Agent has made changes, you can directly access the cloud instance to test:
  • SSH into the sandbox: Access the running Daytona sandbox directly to run commands, check logs, and test functionality
  • VNC preview: While a Cloud Agent is running, you can watch it work in real-time through a VNC URL. Interact with Android Studio and the emulator directly in your browser

Pricing

Cloud Agents require on-demand pricing to be enabled. Cloud Agents are currently only available for teams.

Security

Cloud Agents run in isolated sandbox environments powered by Daytona.io. We never train on your code and only retain code for the duration of the active agent session. What you should know:
  • Grant read-write privileges to the Firebender GitHub App for repos you want to edit. We use this to clone the repo and make changes.
  • Your code runs inside isolated VMs and is stored on VM disks only while the agent is accessible. Code and files are automatically deleted when the session ends.
  • The agent has internet access.
  • The agent auto-runs all terminal commands, letting it iterate on builds and tests. Auto-running introduces data exfiltration risk: attackers could execute prompt injection attacks, tricking the agent to upload code to malicious websites.
