SHELL_DEFAULT_MAX_TIMEOUT_MS

const SHELL_DEFAULT_MAX_TIMEOUT_MS: 600000 = 600000

EXT-125 — default CEILING (ms) on a time budget the MODEL asks for in a shell tool call’s timeoutMs argument, when GthDevToolsConfig.shell does not set maxTimeout.

Ten minutes, because the longest thing a repo’s own dev commands plausibly need is a full test suite, and run_tests is the likeliest of them to want that. Five times the SHELL_DEFAULT_TIMEOUT_MS default gives that room while still bounding a stuck command at an interval a human notices.

The ceiling matters more than the default does. The default is what a call gets for asking nothing and is easy to raise in config for one project; the ceiling is the only thing standing between a model and an unbounded wait, so it is the number to argue about.
