+# Async Semantic Search Client Implementation Plan
+
+This document outlines the step-by-step plan for implementing an asynchronous wrapper around the existing `SemanticSearchClient` to enable background indexing and non-blocking operations.
+
+## Ground Rules
+- Don't change the logic of the existing synchronous client
+- Don't delete existing methods
+- Use "extract until you drop it clean" approach
+- Ensure all tests pass after each step
+- Update tests as needed to work with the new async functionality
+
+## Implementation Instructions
+
+If this session gets closed at any time, you can continue from where you left off by:
+1. Checking which steps are marked as completed in this file
+2. Running `cargo build` to see if there are any compilation errors
+3. Running `cargo test -p semantic_search_client` to check if tests are passing
+4. Continuing with the next uncompleted step
+
+## Implementation Steps
+
+### Step 1: Add Status Enum to MemoryContext ✅
+- [x] Add `ContextStatus` enum with `Indexing`, `Ready`, and `Failed` variants
+- [x] Update `MemoryContext` struct to include a `status` field
+- [x] Update the constructor to accept status parameter
+- [x] Update serialization/deserialization if needed
+- [x] Update tests to accommodate the new field
+
+### Step 2: Add Empty Context Constructor to SemanticContext ✅
+- [x] Add `new_empty` method to `SemanticContext`
+- [x] Ensure it creates a valid but empty context
+- [x] Verify tests still pass
+
+### Step 3: Add Dependencies to Cargo.toml ✅
+- [x] Add tokio with appropriate features
+- [x] Add async-trait
+- [x] Make dependencies optional with a feature flag
+- [x] Verify build succeeds with the new dependencies
+
+### Step 4: Create AsyncSemanticSearchClient Wrapper ✅
+- [x] Create a new struct `AsyncSemanticSearchClient` that wraps `SemanticSearchClient`
+- [x] Implement basic constructor methods (`new`, `new_with_default_dir`)
+- [x] Add necessary dependencies (tokio, async-trait)
+- [x] Ensure the wrapper compiles without errors
+
+### Step 5: Implement Basic Async Methods ✅
+- [x] Implement `search_all` async method
+- [x] Implement `search_context` async method
+- [x] Implement `get_all_contexts` async method
+- [x] Add tests for these basic methods
+
+### Step 6: Implement Background Indexing Example ✅
+- [x] Add example test showing how to use tokio::task::spawn_blocking for background indexing
+- [x] Add test with progress tracking for larger datasets
+- [x] Update TextEmbedderTrait to implement Sync for thread safety
+- [x] Ensure all tests pass
+
+## Progress Tracking
+
+We'll mark each step as completed (✅) once it's implemented and all tests pass.
