It’s interesting to see the solution that the AI came up with, but WebdriverIO and Appium already exist for this use case, are open source like Capacitor, and come recommended from the Capacitor developers. https://ionic.io/blog/introducing-the-ionic-end-to-end-testi...

the worktree discipline failure is the most interesting part of this post to me. when claude is interactive, "cd into the wrong repo" is catchable. when it's running unattended on a schedule, you find out in the morning.

the abstraction is right - isolated worktree, scoped task, commit only what belongs. the failure is enforcement. git worktrees don't prevent a process from running `cd ../main-repo`. that requires something external imposing the boundary, not relying on the agent to respect it.

what you've built (the 8:47 sweep) is a narrow-scope autonomous job: well-defined inputs, deterministic outputs, bounded time. these work well because the scope is clear enough that deviation is obvious. the harder category is "fix any failing tests" - that task requires judgment about what's in scope, and judgment is exactly where worktree escapes happen.

i've been working on tooling for scheduling this kind of claude work (openhelm.ai) and the isolation problem is front and center. separate working directories per run, no write access to the main repo unless that's the explicit task. your experience here is exactly the failure mode that design is trying to prevent.

The CDP approach for Android is underrated here. Appium adds a translation layer on top of WebViews that often breaks with Capacitor's hybrid rendering. Going direct to Chrome DevTools Protocol means you're using the same primitives the browser uses internally, not fighting through abstraction.

The iOS section is the real story though. The TCC.db dance and AppleScript keyboard limitations feel like archaeological excavation.

Reading through this reminds me of how bot farms will regularly consist of stripped down phones that are essentially just the mainboard hooked up to a controller that simulates the externals.

When struggling with failing to reverse engineer mobile apps for smart home devices, I’ve considered trying to set something like this up for a single device.
