## Commands
- **Compile:** `bun run cli:compile` (esbuild to `dist/openpencil-cli.cjs`)
- **Dev run:** `bun run cli:dev` (run from source via Bun)
## Key Patterns
- **Input methods:** Commands accepting JSON/DSL support inline string, `@filepath`, or `-` (stdin)
- **Connection:** WebSocket to running app instance (desktop or web server)
- **Launcher:** Auto-detects installed desktop app paths per platform (macOS, Windows, Linux)
- **Skill bundle:** `bun run cli:bundle-skill` pre-generates `skill-bundle.json` from `../openpencil-skill/`, embedded into the binary by esbuild. Falls back to git clone at runtime if the bundle is empty.
- **esbuild:** Compiles with `--alias:@=src` to resolve web app imports, `--external:canvas --external:paper`
- **Output:** All commands output JSON; `--pretty` flag for human-readable formatting
- **Global flags:** `--file <path>` (target .op file), `--page <id>` (target page)
