Grepai Trace Callees

When you need to understand what a function actually does under the hood, this traces all the functions it calls. It's the inverse of trace callers: instead of "who uses this?" you get "what does this use?" The output shows you every function call with file locations and context, which is incredibly useful when you're trying to map dependencies, review code for side effects, or figure out if a function is doing too much. Ships with fast and precise modes, and you can export to JSON for scripting. The compact output is thoughtfully designed for AI context windows, which matters more than you'd think when you're chaining this with other analysis tools.
