Android REPL

Use this skill to drive an Android device through the public agent-android beta surface published in the aivanelabs/ai-rpa repo.

Runtime prerequisites:

• agent-android is available on PATH
• if it is missing, install the CLI with uv tool install aivane-agent-android; then run uv tool update-shell if the command is still not found
• the user has provided a trusted device URL such as http://:8080

The public path is local-first:

• the phone hosts the lightweight HTTP service locally
• the desktop connects directly to http://:8080
• UI reads, taps, inputs, and screenshots stay on the phone and controlling machine
• the current tradeoff is LAN-only control; an optional server-side or relay path may arrive later

If an agent-android command suddenly stops working, first check whether the AIVane app or its local API service has exited on the phone.

Safety Boundaries

• Connect only to a device URL explicitly provided by the user.
• Do not scan local networks or guess device IP addresses.
• Treat UI trees and screenshots as sensitive because they may contain private app content.
• Save screenshots or raw UI dumps only when the user explicitly asks for a file output.
• Ask for confirmation before operating sensitive apps, private content, account settings, or irreversible actions.
• Do not expose the phone-side service on a public network.

Core Workflow

Every Android control task should follow the same short loop:

1. Confirm connectivity with /health
2. Discover the target app with apps if needed
3. Launch one app
4. Inspect the current UI tree
5. Perform one action
6. Inspect again

Keep the loop short. Prefer inspect -> act -> inspect over long speculative command chains.

Quick Start

Start the REPL with the user-provided device URL:

• agent-android --repl --url http://:8080

Built-in help:

• agent-android --help
• In the REPL: h

Essential CLI Commands

Use the one-off CLI when you already know the exact action you want.

Connectivity:

• agent-android --health --url http://:8080

Discovery:

• agent-android --apps --url http://:8080
• agent-android --list --url http://:8080
• agent-android --id com.example:id/search --url http://:8080
• agent-android --text Search --url http://:8080
• agent-android --inputs --url http://:8080
• agent-android --refId 7 --url http://:8080
• agent-android --xpath 7 --url http://:8080
• agent-android --get-attr 7 text --url http://:8080

Actions:

• agent-android --launch com.xingin.xhs --url http://:8080
• agent-android --tap 7 --url http://:8080
• agent-android --input 7 "hello world" --url http://:8080
• agent-android --swipe up --url http://:8080
• agent-android --back --url http://:8080
• agent-android --press home --url http://:8080
• agent-android --screenshot --url http://:8080

Waiting and output:

• agent-android --wait-for Search --timeout 30 --url http://:8080
• agent-android --list --raw --url http://:8080

REPL Command Reference

Use the REPL for exploratory tasks and smoke runs. Short aliases and long names both work.

Browse

• health or hl

Check /health.

• l [n] or list [n]

List the first n elements, or all cached elements when n is omitted.

• ss or snapshot

Force-refresh the UI tree and print it again.

• f or find

Filter by text or content description.

• id

Filter by Android resource ID.

• ref

Show the full element detail for one refId.

• x or xpath

Generate XPath candidates and validate their runtime match counts.

• xx

Tap by the best unique generated XPath candidate. Refuses ambiguous matches.

• vx [idx] or validatex [idx]

Validate one XPath against the runtime. Optionally inspect one match by zero-based index.

Interact

• t or tap

Tap the element center point from the current tree.

• tx or tapx

Tap one runtime-resolved XPath target.

• i or input

Input text into a refId target.

Use --clear or "" to clear instead of typing.

• ix or inputx

Input text into one XPath target.

Use ix -- or --clear to clear the field.

• sw [--dur N] [--dist N] or swipe ...

Swipe down/up/left/right with optional duration and distance.

• p or press ...

Press a system key.

• b or back

Press Back.

• la or launch

Launch an app by package name.

• s [path] or screenshot [path]

Capture a screenshot to an auto-generated or explicit path.

Wait And Inspect

• wf [--t N] or waitfor ...

Wait for an element to appear.

• g or get

Read an attribute such as text, class, bounds, x, y, or xpath.

• apps

List launcher apps from /apps.

Session

• raw

Toggle raw JSON mode.

• vars

Show current URL, timeout, raw mode, and tree cache state.

• set timeout 30

Set the default wait timeout in seconds.

• h or help

Show the built-in help text.

• q or quit

Exit the REPL.

Common Patterns

First smoke flow

1. Start the REPL with agent-android --repl --url http://:8080.
2. health
3. apps
4. la
5. l
6. t
7. i hello
8. b
9. s

Find the right package before launch

• apps
• la com.example.app
• l

Inspect an element before using XPath

• l
• ref 12
• x 12
• vx //EditText[@text='Search']

Clear and refill an input

• i 7 --clear
• i 7 hello world
• ix //EditText[@text='Search'] --
• ix //EditText[@text='Search'] -- hello world

Troubleshooting

• If an agent-android command fails, first check whether the AIVane app or phone-side API service has exited.
• If agent-android is not found, run uv tool update-shell, reopen the terminal, and retry.
• Re-open the app or restart the phone-side service, then retry curl http://:8080/health.
• If health works but UI commands fail, run ss to force-refresh the tree before tapping or inputting.
• If tx or ix fails, run vx and make sure the XPath resolves to exactly one runtime match.
• If screenshots fail the first time, confirm the on-device MediaProjection permission prompt was accepted.
• If everything suddenly stops responding, confirm the phone IP did not change and that the desktop is still on the same LAN.

When To Stop

Stop and ask for user help when:

• the device is unreachable on LAN
• the app is not running and cannot be restarted from the current path
• required Android permissions are missing
• launcher discovery returns nothing useful
• the runtime UI no longer matches the expected screen after repeated refreshes
