  Protect Claude Code sessions from context overflow by running a background
  daemon that monitors session size and auto-prunes before compaction hits.
  Use when the user says "guard", "protect session", "context getting long",
  "prevent compaction", "session management", or is running agent teams that
  need continuous context protection.

Start the cozempic guard daemon for continuous session protection.

## Default (recommended)

```bash
cozempic guard --daemon --threshold 50 -rx standard --interval 30
```

This runs in the background and:
1. Checkpoints team state every 30 seconds
2. At 60% of threshold (30MB): applies gentle prune, no reload
3. At threshold (50MB): applies full prescription + auto-reload with team state preserved

## For agent teams

Guard mode is **essential** for sessions running agent teams. Without it, auto-compaction triggers and the lead agent loses team state (TeamCreate, SendMessage, tasks are discarded).

## Options

- `--threshold N` — hard threshold in MB (default: 50)
- `--soft-threshold N` — soft threshold in MB (default: 60% of hard)
- `--threshold-tokens N` — hard threshold in tokens (fires whichever hits first)
- `--no-reload` — prune without restarting Claude
- `--no-reactive` — disable kqueue/polling file watcher
- `-rx NAME` — prescription at hard threshold (default: standard)

## Check status and stop

The daemon writes to `/tmp/cozempic_guard_*.log`. Check with:
```bash
ls /tmp/cozempic_guard_*.pid 2>/dev/null        # is it running?
tail -20 /tmp/cozempic_guard_*.log 2>/dev/null   # recent activity
kill "$(cat /tmp/cozempic_guard_*.pid)"           # stop it
```
