LNAI – Define AI coding tool configs once, sync to Claude, Cursor, Codex, etc.

Meet LNAI, the “one config to rule them all” tool that promises to end the messy ritual of juggling different rule files for every AI helper you use. Instead of feeding separate instructions to Claude, Cursor, Codex, GitHub Copilot and friends, you write once in a simple .ai/ folder and hit sync. The dev who kicked off the thread confessed they were constantly forgetting to update one tool, leading to inconsistent suggestions across apps. Fans are calling LNAI a sanity-saver with automatic clean‑up for stale files—think Marie Kondo for your AI configs.

But the honeymoon ended fast. One camp is waving a big red flag: if each AI model needs a different tone and rules, won’t a single shared setup water down results? Another asks the killer question: what happens when tools cache old settings—does your “sync once” actually sync? The hottest skeptics are dubbing it a one-size-fits-none, probing conflict handling (“what if two tools want different formats for the same thing?”). There’s even a pragmatic crowd rolling their eyes and saying they already solved this with dotfile managers like chezmoi. So yes, LNAI lands with big promise—one source of truth and instant updates—but the comments are spicy: believers want relief from config chaos, purists want model‑specific finesse, and ops‑minded folks want proof the sync story won’t break when reality hits. Grab popcorn, the config wars just got a main character.
