What is smart-screen CLAUDE.md?

A project guide for Smart Screen, a desktop app built with Electron, React, and TypeScript for recording screen demonstrations and turning them into walkthrough videos. It describes the commands, two-process design, and flow between recording, analysis, and editing.

Use it when building or testing screen recording, mouse and keyboard tracking, transcription, AI or local analysis, the timeline editor, or the Electron-to-interface connection.

It helps the coding agent keep privileged desktop work, such as recording and secret storage, separate from the user interface, reducing architectural mistakes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00927	$0.00927
Opus 5.5	$0.00371	$0.00371
Sonnet 5.5	$0.00185	$0.00185
Haiku 4.5	$0.00093	$0.00093

Security

Grade A, and why

smart-screen CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Commands

npm run dev              # Start Electron + Vite dev server
npm run build            # Full production build (native tools + TS + Vite + Electron Builder)
npm run lint             # Check code with Biome
npm run lint:fix         # Auto-fix linting issues
npm run format           # Auto-format with Biome
npm test                 # Run Vitest test suite once
npm run test:watch       # Run tests in watch mode

To run a single test file:

npx vitest run src/smart-demo/timelineAnalyzer.test.ts

Architecture

This is an Electron + React + TypeScript desktop app for recording screen demos and creating polished walkthrough videos with AI or local heuristic analysis.

Process Model

Two distinct processes — keep their responsibilities separate:

Main Process (/electron/) — privileged: recording lifecycle, native macOS telemetry (click/keyboard monitors), transcription pipeline, AI provider calls, secure secret storage
Renderer Process (/src/) — React UI: HUD overlay, source selector, timeline editor
IPC Bridge (/electron/preload.ts, /electron/ipc/handlers.ts) — 50+ contextBridge channels connect the two
Shared Types (/shared/) — cross-process TypeScript contracts; changes here affect both sides

Key Data Flow

Recording → cursor sampled at 10 Hz → .webm video + .webm.cursor.json sidecar
Load → IPC retrieves telemetry sidecar
Local Smart Demo (/src/smart-demo/) → deterministic heuristics detect clicks, typing, navigation, silence
Optional AI (/electron/ai/) → BYOK OpenAI or local Ollama; request built in renderer (/src/lib/ai/), executed in main
Edit → apply zooms, trims, captions, annotations in timeline editor
Export → decode video frames → render overlays (Pixi.js/Canvas) → re-encode MP4 or GIF

Operating Modes

The app is offline-first — fully functional without any AI provider:

Offline — local Smart Demo heuristics only
Hybrid — local heuristics + optional BYOK AI refinement (OpenAI)
Local AI — Ollama for on-device LLM

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
