-# Caffeinate
-
-A Claude Code plugin that blocks `sleep` commands and reminds Claude to use background tasks instead.
-
-## Purpose
-
-When Claude uses `sleep` commands in Bash, it blocks the session unnecessarily. This plugin intercepts these commands and suggests using proper async patterns like:
-
-- `run_in_background: true` parameter for long-running commands
-- Polling for conditions instead of sleeping
-- Proper async/background task patterns
-
-## Installation
-
-```bash
-# From the plugin directory
-claude --plugin-dir /path/to/caffeinate
-```
-
-Or copy to your project's `.claude-plugin/` directory.
-
-## What Gets Blocked
-
-| Command | Blocked? | Reason |
-|---------|----------|--------|
-| `sleep 5` | Yes | Direct sleep command |
-| `sleep $TIMEOUT` | Yes | Sleep with variable |
-| `echo "test" && sleep 5` | Yes | Sleep after separator, outside quotes |
-| `cmd; sleep 10` | Yes | Sleep after semicolon |
-| `echo "sleep 8 hours"` | No | Sleep is inside quotes (not a command) |
-| `echo "foo && sleep 5"` | No | Entire sleep pattern is in a string |
-
-## How It Works
-
-The plugin uses a `PreToolUse` hook on the `Bash` tool to:
-
-1. Check if commands start with `sleep`
-2. Detect `sleep` after command separators (`&&`, `||`, `;`, `|`)
-3. Use quote-counting to avoid false positives when `sleep` appears inside strings
-
-## Alternatives to Sleep
-
-Instead of:
-```bash
-sleep 5 && check_status
-```
-
-Use background execution:
-```bash
-# Run in background with run_in_background: true
-long_running_command
-```
-
-Or poll for conditions:
-```bash
-# Poll for a file to exist
-while [ ! -f /tmp/ready ]; do :; done
-```
