Cozempic

50,000+ 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 18 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
• Interactive "prune now?" nudge — a non-blocking heads-up at 25% / 55% / 80% context (once per tier) recommending cozempic reload, so interactive users get cozempic's higher-fidelity prune+resume on their own terms instead of falling back to lossy autocompact. Takes no action on its own; silence with COZEMPIC_NUDGE_OFF=1
• Interactive-safe reload — in interactive sessions the guard warns first and reloads only at an idle breakpoint (never mid-turn); headless sessions reload as before
• Safe-point protection — the guard never terminates-and-resumes through in-flight work: a running Workflow, a background subagent, an agent team, or an open tool call defers the reload so nothing is lost
• compact-summary-collapse — 85-95% savings by removing pre-compaction messages already in the summary
• Agent Teams protection — ch
