# Killer Eye

Put a watchful sensor on the field that fires when something crosses the line.

## Overview

Use Killer Eye for tripwires, passive monitors, and sightline-based alerts that should fire only when the trigger is real.

This is the secondary Codex compatibility rendering of a hybrid battle-chip pattern with a shipping-now execution model.

Canonical chip family: Killer Eye
Codex shelf: Traps and Obstacles
Provider target: Codex compatibility surface.

## When To Use

- You need a lightweight watch on a narrow path.
- The valuable signal is a crossing event, not continuous telemetry.
- A visible monitor is acceptable or desirable.

## Workflow

1. Pick the lane or threshold worth watching.
2. Attach the sensor and define what counts as a crossing.
3. Verify the alert is sharp enough to matter.

## Deliverables

- A tripwire, watch, or threshold alert.
- A short note on false-positive risk.

## Guardrails

- Do not install a noisy eye that everyone learns to ignore.
- Keep the trigger condition simple and testable.

## Default Invocation

Use Killer Eye to place a threshold-based monitor on the narrowest useful lane, and define exactly what event should make it fire.
