File contents

You are helping the user install and configure claude-warn-light.

When this skill is invoked, guide the user through these steps.

What it does

Light turns RED when Claude is waiting for your approval
Blinks GREEN twice when you approve
Restores original colour when you deny or the session ends

Supported lights (ordered by setup ease)

Brand	Friction
LIFX	Zero — just on same Wi-Fi
Philips Hue	Press button on bridge
Home Assistant	URL + token — works with any brand
Yeelight / Xiaomi	Enable LAN mode in app
WLED	IP address
Tuya / Wipro / Smart Life	Needs IoT developer key

Installation

Step 1 — Get the code

git clone https://github.com/YOUR_USERNAME/claude-warn-light.git
cd claude-warn-light

Step 2 — Run the setup wizard

python3 setup.py

The wizard will:

Scan your local network and show what lights it finds
Ask you to pick one (auto-detected lights are highlighted)
Walk through the minimum config for that type
Run a live test (red → green blink → restore)
Register the Claude Code hooks automatically

That's it. No manual editing of settings files.

After setup

Re-run setup anytime to switch lights:

python3 setup.py

Test the light sequence manually:

python3 controller.py test

Manually restore if the light gets stuck red:

python3 controller.py restore

Troubleshooting

Problem	Fix
Light doesn't respond	Check it's on the same Wi-Fi. Run `python3 controller.py test`
Light stays red after denial	Run `python3 controller.py restore`
Config lost	Re-run `python3 setup.py`
LIFX not found	Restart the bulb; ensure same subnet
Yeelight not found	App → bulb → Settings → LAN Control → ON
Hue button didn't work	Press within 30 seconds and try again

How hooks work

The wizard registers three Claude Code hooks in ~/.claude/settings.json:

Notification → turns light RED (Claude is waiting for attention)
PreToolUse → blinks GREEN + restores (user approved, tool about to run)
Stop → restores (session ended or denied while red)

All hooks fail silently so they never block Claude.
