## About

# Shark Loop (External Enforcer)

Run the shark loop enforcer script which wraps `claude --print` with a hard OS-level timeout per turn.

## Instructions

Parse the arguments:
- The main text is the TASK_DESCRIPTION
- `--max-loops N` sets SHARK_MAX_LOOPS (default: 50)
- `--timeout S` sets SHARK_LOOP_TIMEOUT in seconds (default: 25)

On Windows (PowerShell), run:
```powershell
$env:SHARK_MAX_LOOPS = ""
$env:SHARK_LOOP_TIMEOUT = ""
& "$SKILL_DIR\..\shark.ps1" ""
```

On Linux/Mac, run:
```
SHARK_MAX_LOOPS= SHARK_LOOP_TIMEOUT= bash "$SKILL_DIR/../shark.sh" ""
```
