Cozempic

20,000+ power users trust Cozempic to keep their Claude Code sessions lean.

Context cleaning for Claude Code ��� remove the bloat, keep everything that matters, protect Agent Teams from context loss.

What It Does

Claude Code sessions fill up with dead weight: progress ticks, thinking blocks, stale file reads, duplicate CLAUDE.md injections, base64 screenshots, oversized tool outputs, and metadata bloat. A typical session carries 8-46MB — most of it noise that inflates every API call.

Cozempic removes it with 17 composable strategies across 3 prescription tiers, while your actual conversation, decisions, and working context stay untouched. The guard daemon runs automatically — install once, forget about it.

Key Features

• 18 pruning strategies — gentle (5), standard (11), aggressive (18)
• Guard daemon — auto-starts via SessionStart hook, monitors and prunes continuously
• compact-summary-collapse — 85-95% savings by removing pre-compaction messages already in the summary
• Agent Teams protection — checkpoints team state through compaction, reactive overflow recovery
• Behavioral digest — extracts your corrections ("don't do X"), persists them to Claude Code's memory system so they survive compaction
• 8 doctor checks — diagnose and auto-fix session corruption, orphaned tool results, zombie teams
• Token-aware diagnostics — exact token counts from usage fields, cache hit rate, context % bar
• Auto-detects 1M context — correct thresholds for both 200K and 1M models
• Auto-updates — checks PyPI daily, upgrades in-place

Zero external dependencies. Python 3.10+ stdlib only.

Install

pip install cozempic
cozempic init

That's it. The guard daemon auto-starts on every session via hooks. No second terminal needed.
