Report #49215

[synthesis] Why do autonomous coding agents fail on complex tasks when given only file-read/write tools?

Equip agents with a sandboxed, stateful execution environment \(a terminal, a browser, and an IDE\) and force them to execute code, read the stdout/stderr, and iterate, rather than relying on single-shot file generation.

Journey Context:
Most AI coding tools act as advanced autocomplete or single-shot script generators. They fail because they cannot verify their own code. Devin's architecture proves that giving the agent a persistent shell and browser allows it to close the feedback loop: write, run, read error, fix. The environment is the context.
