- Remove the arbitrary 60-second read timeout on the Neovim socket that caused the read task to exit during idle periods, permanently locking the connection state.
- Automatically clear the connection state variable when the read loop breaks (e.g. true EOF), allowing get_nvim_connection() to correctly auto-reconnect on the next call.
- Increase the Neovim RPC call timeout from 10s to 30s to accommodate heavier operations (e.g., massive Lua regex substitutions) without falsely dropping the connection.
- Add
vim_close_window to unsplit active layout without destroying underlying buffer.
- Add
vim_list_windows to discover active splits.
- Add
vim_get_active_window and
vim_set_active_window to programmatically navigate windows.
- Added nvim_set_extmark tool schema and handler
- Implemented lua bridge using vim.api.nvim_buf_set_extmark to dynamically overlay ghost text and highlight groups onto active buffers
- Created global thread-safe NvimState to shadow Neovim context.
- Injected Lua autocmds (CursorMoved, TextChanged) on connection to stream events back to MCP.
- Upgraded msgpack RPC loop to intercept and parse 'mcp_event' notifications alongside standard responses.
- Optimized nvim_get_cursor to pull instantly from the local shadow buffer, bypassing RPC round-trips.
- Offloaded the blocking idx.commit() inside index_committer_worker to okio::task::spawn_blocking to prevent the tokio async thread from being starved by blocking I/O.
- Removed expensive full HashMap .clone() operations during UI client websocket broadcasts in both handle_socket and
vim_telemetry_handler, filtering and collecting only the Sender handles.
- Migrated blocking std::fs::write calls across the WSL 9P boundary in
vim_telemetry_handler over to asynchronous okio::fs::write().await to prevent severe async thread blockages on native file I/O delays.
