 # AGENTS.md
 
-**Agents:**
-- Update `agentydragon/README.md` with a brief summary of your work (features, fixes, refactors, documentation, etc.) whenever you make changes to this repository.
-- Read `agentydragon/README.md` for the branch-level changelog and guidelines on task conventions.
-- For work on tasks, “add task” means creating a new Markdown file under `agentydragon/tasks/` using `task-template.md`:
-  - Name it with a two-digit prefix and kebab-case slug (e.g. `14-new-feature.md`).
-  - Fill in the **Status**, **Goal**, **Acceptance Criteria**, and **Implementation** sections.
-- No central task list should be maintained. The AI assistant will include these branch-level notes in its context.
+This file provides guidance to OpenAI Codex (openai.com/codex) when working with
+code in this repository.
 
-# Rust/codex-rs
+## Build, Lint & Test
 
-In the codex-rs folder where the rust code lives:
+### JavaScript/TypeScript
+- Install dependencies: `pnpm install`
+- Run all tests: `pnpm test`
+- Run a single test: `pnpm test -- -t <pattern>` or `pnpm test -- path/to/file.spec.ts`
+- Watch tests: `pnpm test:watch`
+- Lint: `pnpm lint && pnpm lint:fix`
+- Type-check: `pnpm typecheck`
+- Format: `pnpm format:fix`
+- Build: `pnpm build`
 
-- Never add or modify any code related to `CODEX_SANDBOX_NETWORK_DISABLED_ENV_VAR`. You operate in a sandbox where `CODEX_SANDBOX_NETWORK_DISABLED=1` will be set whenever you use the `shell` tool. Any existing code that uses `CODEX_SANDBOX_NETWORK_DISABLED_ENV_VAR` was authored with this fact in mind. It is often used to early exit out of tests that the author knew you would not be able to run given your sandbox limitations.
+### Rust (codex-rs workspace)
+- Build: `cargo build --workspace --locked`
+- Test all: `cargo test --workspace`
+- Test crate: `cargo test -p <crate>`
+- Single test: `cargo test -p <crate> -- <test_name>`
+- Format & check: `cargo fmt --all -- --check`
+- Lint: `cargo clippy --all-targets --all-features -- -D warnings`
+
+## Code Style Guidelines
+
+- JS/TS: ESLint + Prettier; group imports; camelCase vars & funcs; PascalCase types/components; catch specific errors
+- Rust: rustfmt & Clippy (see `codex-rs/rustfmt.toml`); snake_case vars & funcs; PascalCase types; prefer early return; avoid `unwrap()` in prod
+- General: Do not swallow exceptions; use DRY; generate/validate ASCII art programmatically
+- Include any Cursor rules from `.cursor/rules/` or Copilot rules from `.github/copilot-instructions.md` if present

 ## Summary
@@ -23,11 +23,15 @@ Add a user-facing affordance (e.g. a hotkey) to invoke arbitrary shell commands
 ## Implementation
 
 **How it was implemented**  
-- Define a new keybinding (configurable, default Ctrl+M) in the TUI to trigger a `ShellCommandPrompt` overlay.
-- In the overlay, accept arbitrary user input and dispatch it as a `ToolInvocation(ShellTool, command)` event in the agent’s event loop.
-- Leverage the existing shell tool backend to execute the command in the container and capture its output.
-- Render the command invocation and result inline in the chat UI using the command-rendering logic (honoring compact mode and spacing options).
-- Add integration tests to simulate the hotkey, input prompt, and verify the shell tool call and inline rendering.
+- Added a new slash command `Shell` and updated dispatch logic in `app.rs` to push a shell-command view.
+- Bound `Ctrl+M` in `ChatComposer` to dispatch `SlashCommand::Shell` for hotkey-driven shell prompt.
+- Created `ShellCommandView` (bottom pane overlay) to capture arbitrary user input and emit `AppEvent::ShellCommand(cmd)`.
+- Extended `AppEvent` with `ShellCommand(String)` and `ShellCommandResult { call_id, stdout, stderr, exit_code }` variants for round-trip messaging.
+- Implemented `ChatWidget::handle_shell_command` to execute `sh -c <cmd>` asynchronously (tokio::spawn) and send back `ShellCommandResult`.
+- Updated `ConversationHistoryWidget` to reuse existing exec-command cells to display shell commands and their output inline.
+- Added tests:
+  - Unit test in `shell_command_view.rs` asserting correct event emission (skipping redraws).
+  - Integration test in `chat_composer.rs` asserting `Ctrl+M` opens the shell prompt view and allows input.
