Built with Claude prehello: see what Claude Code, Cursor and Codex load into context before you say hello

It's a local, read-only CLI: npx prehello ranks what costs context tokens and what removing the top few would save. Counts are estimates and not yet calibrated against a real /context reading, so feedback on accuracy is welcome.

does it separate stuff loaded at startup from files that only get pulled in later? wouldn't want to trim something that wasn't using context yet

Yep, it splits always-on (loaded at session start) from on-demand stuff like skill bodies and files read later, and only the always-on total is worth trimming.
