WHAT'S //GO:NOSPLIT FOR?

Go's `//go:nosplit` directive removes the usual stack overflow check from functions to improve performance. Nosplit functions skip the preemption check that normally compares the stack pointer against a limit and calls `runtime.morestack` when needed, making them about 2% faster in hot loops but potentially much faster when the goroutine struct isn't cached. However, nosplit functions are dangerous because they can cause stack overflows, so the Go linker includes safety checks to make sure chains of nosplit functions don't exceed a small stack limit (792 bytes).

WHAT CAN AGENTS ACTUALLY DO?

AI agents use LLMs to evaluate contexts, suggest and utilize tools to enrich those contexts, and manage flow control for tool usage. Customer support and bug triaging are good use case examples, and AI agents should be treated as software products requiring careful design, iteration, and human oversight.
