# Implementation Plan: Effects Documentation and Demo Script

**Track ID:** effects-docs_20260318
**Spec:** [spec.md](./spec.md)
**Created:** 2026-03-18
**Status:** [x] Complete

## Overview

Update existing effects documentation pages to cover all 18 new effects (with attribution to pkivolowitz/lifx), update the API reference, create an example demo script with device-type-aware effect selection, and generate animated GIFs of each effect using the LIFX emulator and Playwright.

## Phase 1: Documentation Updates

Update the getting-started and API docs to cover the new effects.

### Tasks

- [x] Task 1.1: Update `docs/getting-started/effects.md` — add a new section for the 18 ported effects with attribution to pkivolowitz/lifx, brief descriptions, key parameters, and device compatibility notes
- [x] Task 1.2: Update `docs/api/effects.md` — add API reference entries for all new effect classes using mkdocstrings
- [x] Task 1.3: Verify `mkdocs build` succeeds with no warnings

### Verification

- [x] `mkdocs build` passes cleanly
- [x] New effects section visible in local `mkdocs serve`

## Phase 2: Example Script

Create the demo script with device-type detection and effect cycling.

### Tasks

- [x] Task 2.1: Create `examples/effects_demo.py` with argparse CLI (`--effect`, `--cycle`, `--ip`, `--serial`, `--duration`)
- [x] Task 2.2: Implement device discovery and type detection (MatrixLight, MultiZoneLight, Light)
- [x] Task 2.3: Implement single-effect mode (`--effect <name>`) with device-appropriate effect selection
- [x] Task 2.4: Implement cycle mode (`--cycle`) that rotates through compatible effects with configurable duration
- [x] Task 2.5: Add PEP 723 inline metadata and usage docstring

### Verification

- [x] Script runs with `uv run examples/effects_demo.py --help`
- [x] Script runs against emulated devices with `--ip` and `--effect`

## Phase 3: Animated GIF Capture

Use the LIFX emulator's web visualizer and Playwright MCP to screen-record each effect, then convert to animated GIFs for embedding in documentation.

### Tasks

- [x] Task 3.1: Stand up the LIFX emulator with a multizone device and expose its web visualizer
- [x] Task 3.2: Create a capture script that runs each effect against the emulator, uses the Playwright MCP server to navigate to the visualizer and record the viewport for ~5 seconds per effect
- [x] Task 3.3: Convert recordings to optimized animated GIFs (using ffmpeg or similar)
- [x] Task 3.4: Store GIFs in `docs/assets/effects/` and embed them in `docs/getting-started/effects.md` alongside each effect description
- [x] Task 3.5: Verify GIF file sizes are reasonable (<2MB each) and visually representative

### Verification

- [x] Each of the 18 effects has a corresponding animated GIF
- [x] GIFs render correctly in `mkdocs serve`
- [x] `mkdocs build` succeeds with embedded images

## Final Verification

- [x] All acceptance criteria met
- [x] `mkdocs build` passes
- [x] Example script runs successfully
- [x] Attribution to pkivolowitz/lifx is present in documentation
- [x] Animated GIFs embedded for all effects
- [x] Ready for review
