This plugin intercepts sleep commands in Bash and prompts Claude to use
background execution (run_in_background: true) instead. This keeps the
session responsive during long-running operations.
Features:
- Blocks sleep commands with helpful retry message
- Allows sleep in quoted strings (false positive prevention)
- Catches sleep in compound commands (&&, ||, ;) and loops
- Allows background commands through (run_in_background: true)
