+# Claude Context: Detaching Tauri from Yaak
+
+## Goal
+Make Yaak runnable as a standalone CLI without Tauri as a dependency. The core Rust crates in `crates/` should be usable independently, while Tauri-specific code lives in `crates-tauri/`.
+
+## Project Structure
+```
+crates/           # Core crates - should NOT depend on Tauri
+crates-tauri/     # Tauri-specific crates (yaak-app, yaak-tauri-utils, etc.)
+crates-cli/       # CLI crate (yaak-cli)
+```
+
+## Completed Work
+
+### 1. Folder Restructure
+- Moved Tauri-dependent app code to `crates-tauri/yaak-app/`
+- Created `crates-tauri/yaak-tauri-utils/` for shared Tauri utilities (window traits, api_client, error handling)
+- Created `crates-cli/yaak-cli/` for the standalone CLI
+
+### 2. Decoupled Crates (no longer depend on Tauri)
+- **yaak-models**: Uses `init_standalone()` pattern for CLI database access
+- **yaak-http**: Removed Tauri plugin, HttpConnectionManager initialized in yaak-app setup
+- **yaak-common**: Only contains Tauri-free utilities (serde, platform)
+- **yaak-crypto**: Removed Tauri plugin, EncryptionManager initialized in yaak-app setup, commands moved to yaak-app
+- **yaak-grpc**: Replaced AppHandle with GrpcConfig struct, uses tokio::process::Command instead of Tauri sidecar
+
+### 3. CLI Implementation
+- Basic CLI at `crates-cli/yaak-cli/src/main.rs`
+- Commands: workspaces, requests, send (by ID), get (ad-hoc URL), create
+- Uses same database as Tauri app via `yaak_models::init_standalone()`
+
+## Remaining Work
+
+### Crates Still Depending on Tauri (in `crates/`)
+1. **yaak-git** (3 files) - Moderate complexity
+2. **yaak-plugins** (13 files) - **Hardest** - deeply integrated with Tauri for plugin-to-window communication
+3. **yaak-sync** (4 files) - Moderate complexity
+4. **yaak-ws** (5 files) - Moderate complexity
+
+### Pattern for Decoupling
+1. Remove Tauri plugin `init()` function from the crate
+2. Move commands to `yaak-app/src/commands.rs` or keep inline in `lib.rs`
+3. Move extension traits (e.g., `SomethingManagerExt`) to yaak-app or yaak-tauri-utils
+4. Initialize managers in yaak-app's `.setup()` block
+5. Remove `tauri` from Cargo.toml dependencies
+6. Update `crates-tauri/yaak-app/capabilities/default.json` to remove the plugin permission
+7. Replace `tauri::async_runtime::block_on` with `tokio::runtime::Handle::current().block_on()`
+
+## Key Files
+- `crates-tauri/yaak-app/src/lib.rs` - Main Tauri app, setup block initializes managers
+- `crates-tauri/yaak-app/src/commands.rs` - Migrated Tauri commands
+- `crates-tauri/yaak-app/src/models_ext.rs` - Database plugin and extension traits
+- `crates-tauri/yaak-tauri-utils/src/window.rs` - WorkspaceWindowTrait for window state
+- `crates/yaak-models/src/lib.rs` - Contains `init_standalone()` for CLI usage
+
+## Git Branch
+Working on `detach-tauri` branch.

+
+## Testing
+- Run `cargo check -p <crate>` to verify a crate builds without Tauri
+- Run `npm run app-dev` to test the Tauri app still works
+- Run `cargo run -p yaak-cli -- --help` to test the CLI
