| name | conductor-metro-debugger |
| description | Inspect a running app's JS runtime, logs, and network with the conductor CLI — evaluate JS in React Native (Hermes) or the web page, dump the React component tree, read console/Metro/device logs, and inspect or issue HTTP requests. Use when debugging app behavior, reading logs, evaluating expressions in the live runtime, inspecting React components, or examining network traffic. |
Conductor — runtime debugging, logs & network
Inspect what a running app is doing under the UI — its JS runtime, console
output, and HTTP traffic. Works against React Native (Hermes/Fusebox) and
Playwright web.
Runtime (React Native / web)
| Command | Purpose |
|---|
conductor debug status [--port N] | RN debugger connection info |
conductor debug evaluate <expr> [--port N] | Run JS in the app runtime (Hermes or web page) |
conductor debug component-tree [--port N] | On-screen React component tree |
conductor debug inspect-element <x,y> | React component at a screen point |
conductor debug log-registry [--source metro] | Summarize recent Metro/Hermes console logs |
Logs
| Command | Purpose |
|---|
conductor logs --recent <n> | Last N buffered log lines — agent-friendly, exits immediately |
conductor logs [--source metro|device] [--level …] [--json] [--duration s] | Stream logs (bound it with --duration) |
conductor logs --list | List Metro debugger targets for this device |
Prefer logs --recent N over a bare logs stream — don't leave a stream
running indefinitely.
Network
| Command | Purpose |
|---|
conductor network logs [--limit N] | Recent HTTP traffic (RN fetch/XHR shim; web via Playwright) |
conductor network request <url> [--method M] [--body STR] [--header K=V] | Issue an HTTP request from the app's context |
Metro bundler
| Command | Purpose |
|---|
conductor metro reload [--port N] [--target N] | Reload the JS bundle without restarting native |
conductor metro stop [--port N] | Stop the Metro bundler on a port (default 8081) |
Tips
--port N targets a specific Metro/debugger port when auto-detection isn't enough.- Add
--json for machine-readable output.
