The JSON DescribeNode tree dwarfed the actual tap targets — on a Settings homepage you'd scroll past ~10 nested LinearLayouts before hitting the useful nodes, and the agent's tool-result became unreadable. iOS masked this because the AX service pre-filters; Android exposed the full uiautomator hierarchy. Two changes in this commit: 1. `formatDescribeTreeAsText` renders the tree as a one-node-per-line outline: `Role [x,y wxh] label='…' id='…' value='…'`, 2-space indent per depth. Same shape as `debugger-component-tree`, easy for the agent to scan. 2. `filterDescribeTree` drops noise containers (LinearLayout, FrameLayout, AXGroup, etc.) and decorative leaves (StaticText / Image with no label). Useful descendants survive at the parent's level. Roles in INTERACTABLE_ROLES (Button, Switch, ScrollView, AXButton, …) survive even without a label since the agent can still tap them. Contract: DescribeResult.tree changes type DescribeNode -> string. The adapters (adaptAXDescribeToDescribeResult, parseUiAutomatorDump, adaptNativeDescribeToDescribeResult) still produce DescribeNode internally; only the tool boundary stringifies. existing describe-tool tests now assert on rendered substrings; the AX/native/contract adapter tests are unchanged.
Argent is an agentic toolkit that gives your AI assistant direct access to iOS Simulators and Android Emulators. Ask it to tap a button, run a profiler or reproduce an issue manually - all from within your CLI, without switching context.
npx @swmansion/argent init
Capabilities
- Autonomous iOS and Android development - Allow your agent to work with iOS and Android apps on its own - let it build, open, interact with the app and debug it. Ask for reproducing issues, testing features manually, profiling your app and much more, without ever interrupting your work.
- UI interaction - Give your agent full control toolkit - tapping, swiping, pinching, typing, gestures, hardware buttons and all other gears included. Let it navigate your app exactly as a user would, without lifting a finger.
- Profiling with batteries included - Argent can perform and analyze both React-Native and Xcode Instruments profiling sessions. Get comprehensive summaries and ask to optimise your app where you find fit.
- Debugging and diagnostics - Let your agent inspect logs, capture crash reports, and reproduce failing states on the simulator, so you can jump straight to the fix.
- React Native out of the box - Argent works with React Native apps natively, so your agent can build, launch, and iterate on your RN project the same way it would any iOS app - no extra setup required.
Tip: Once installed, ask your assistant "What can Argent do?" - it will walk you through all capabilities available.

Privacy
Argent does not collect or transmit any user data. No telemetry, no analytics, no crash reporting.
- Argent integrates with your agent locally over MCP stdio.
- Its internal tools are not reachable from outside your machine.
- The only outbound network call we make is the version check against our public npm package, which sends no user data and fails gracefully if blocked.
