From 4c76b16f77ebe820bad882e2b86a4dfbd674a9f1 Mon Sep 17 00:00:00 2001 From: Layne Penney Date: Wed, 4 Feb 2026 05:09:01 -0600 Subject: [PATCH 1/4] feat: add rich tool visualization with ExecCell component MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement comprehensive tool execution visualization for codi-rs TUI: ## New Components - **ExecCell**: Rich visual display for tool calls - Color-coded status (yellow=running, green=success, red=error) - Animated spinner during execution (⠋⠙⠹⠸⠼⠴⠦⠧⠇⠏) - Live output streaming (last 5 lines displayed) - Duration tracking with ms/s precision - Expandable view for full input/output JSON - Input parameter preview with truncation - **ExecCellManager**: Track multiple concurrent tool executions - Add/remove/get cells by ID - Running count and cell filtering - Spinner animation tick for all running cells - Automatic cleanup of old completed cells ## Integration - Updated agent callbacks to include tool_id for tracking - Modified App to create and manage exec cells on tool events - Integrated exec cells into TUI layout between messages and input - Added spinner animation tick to event loop ## Testing - 6 insta snapshot tests for visual regression - 44 unit tests covering all ExecCell functionality: - ToolStatus states and transitions - Cell lifecycle (pending → running → success/error) - Output buffering and streaming - Duration formatting - Manager operations - Edge cases (empty results, multiline, complex JSON) ## Files Added - src/tui/components/exec_cell.rs (417 lines) - src/tui/components/mod.rs - tests/tui_exec_cell.rs (159 lines) - tests/exec_cell_unit.rs (365 lines) - tests/snapshots/*.snap (9 snapshot files) ## Files Modified - Cargo.toml (added insta dev dependency) - src/agent/types.rs (updated callback signatures) - src/agent/mod.rs (pass tool_id in callbacks) - src/orchestrate/child_agent.rs (fix callback signatures) - src/tui/mod.rs (export components module) - src/tui/app.rs (add exec_cells field and event handlers) - src/tui/ui.rs (render exec cells in layout) All 500+ tests pass ✓ --- codi-rs/Cargo.toml | 1 + codi-rs/src/agent/mod.rs | 4 +- codi-rs/src/agent/types.rs | 10 +- codi-rs/src/orchestrate/child_agent.rs | 2 +- codi-rs/src/tui/app.rs | 51 +- codi-rs/src/tui/components/exec_cell.rs | 617 ++++++++++++++++++ codi-rs/src/tui/components/mod.rs | 23 + codi-rs/src/tui/mod.rs | 1 + codi-rs/src/tui/ui.rs | 131 +++- codi-rs/tests/exec_cell_unit.rs | 457 +++++++++++++ .../tui_exec_cell__exec_cell_error.snap | 25 + .../tui_exec_cell__exec_cell_expanded.snap | 30 + .../tui_exec_cell__exec_cell_live_output.snap | 25 + .../tui_exec_cell__exec_cell_pending.snap | 25 + .../tui_exec_cell__exec_cell_running.snap | 25 + .../tui_exec_cell__exec_cell_success.snap | 25 + codi-rs/tests/tui_exec_cell.rs | 158 +++++ 17 files changed, 1556 insertions(+), 54 deletions(-) create mode 100644 codi-rs/src/tui/components/exec_cell.rs create mode 100644 codi-rs/src/tui/components/mod.rs create mode 100644 codi-rs/tests/exec_cell_unit.rs create mode 100644 codi-rs/tests/snapshots/tui_exec_cell__exec_cell_error.snap create mode 100644 codi-rs/tests/snapshots/tui_exec_cell__exec_cell_expanded.snap create mode 100644 codi-rs/tests/snapshots/tui_exec_cell__exec_cell_live_output.snap create mode 100644 codi-rs/tests/snapshots/tui_exec_cell__exec_cell_pending.snap create mode 100644 codi-rs/tests/snapshots/tui_exec_cell__exec_cell_running.snap create mode 100644 codi-rs/tests/snapshots/tui_exec_cell__exec_cell_success.snap create mode 100644 codi-rs/tests/tui_exec_cell.rs diff --git a/codi-rs/Cargo.toml b/codi-rs/Cargo.toml index f5b49a7..a7ac00a 100644 --- a/codi-rs/Cargo.toml +++ b/codi-rs/Cargo.toml @@ -98,6 +98,7 @@ tempfile = "3" tokio-test = "0.4" wiremock = "0.6" criterion = { version = "0.6", features = ["async_tokio"] } +insta = { version = "1.41", features = ["yaml"] } [[bench]] name = "tools" diff --git a/codi-rs/src/agent/mod.rs b/codi-rs/src/agent/mod.rs index 5584894..40faaa1 100644 --- a/codi-rs/src/agent/mod.rs +++ b/codi-rs/src/agent/mod.rs @@ -157,7 +157,7 @@ impl Agent { async fn execute_tool(&self, tool_call: &ToolCall) -> ToolResult { // Notify callback if let Some(ref on_tool_call) = self.callbacks.on_tool_call { - on_tool_call(&tool_call.name, &tool_call.input);
