[Bug] /resume loads incomplete session context despite full file on disk #22614
Description
I've now reproduced the issue with precise measurements:
Test performed today (Feb 2):
- Worked session to 97% context (194.38k/200k tokens, 606 intents)
- Used /exit
- Used /resume to return to same session
- Context dropped to 11% (22.84k/200k tokens)
- Assistant had no memory of conversation ("What are we working on?")
Session file verified:
- File size: 6.75MB (complete)
- 866+ message lines in JSONL
- No truncation, full content preserved on disk
- Only summary entry: "User Exit Session" at end
Key finding: The session file contains the full conversation, but /resume only loads ~11% of it. This is consistent across multiple large sessions (I have 44
sessions totaling 80MB in ~/.claude/projects/).
This appears to be a resume loading issue, not a storage issue. Happy to provide session files or additional logs if helpful.
Version: 2.1.29
OS: Ubuntu 24.04 (Linux 6.8.0-90-generic)
Best,

This might be related to the session file being too large for full context loading — Claude loads what it can and drops the rest.
Cozempic can help by pruning redundant data from the session file before resume, so more of the actual conversation fits in context:
It removes progress ticks (40-48% of typical files), stale file reads, oversized tool outputs, and duplicate documents — while preserving the actual conversation DAG. This means more of your real session content survives the resume.
