kept losing good conversations to /compact. you spend 40 minutes having claude map your codebase, it builds up real understanding, then context fills up and /compact crushes everything into a 3k token summary. "we discussed auth and decided on JWT." cool thanks.

dug into the actual session JSONL files and the breakdown is kind of absurd -- 60-70% is raw file contents from tool reads that claude already synthesized, another 15-20% is base64 thinking signatures. your actual conversation is like 10-15% of the window.

so i built cmv. it strips the junk and keeps every message verbatim. tool results over 500 chars become stubs, thinking sigs get removed, everything you said stays.

cmv trim --latest # trim and relaunch, 20-70% smaller (milage varies depending on tool and context session etc.)

cmv snapshot "analysis" --latest # save a session state

cmv branch "analysis" --name "auth" # fork from it later

also has a TUI dashboard that shows the token breakdown per session so you can see what's eating your context before you do anything.

what it's not:

* not a token monitor (ccusage etc already do that)

* doesn't touch original sessions, everything creates copies

* local only, reads JSONL directly, no API calls

curious how others handle this. most people seem to just accept /compact but losing a deep architectural discussion to a bullet point summary felt wrong enough to build something.
