Make agents and skills commands usable beyond placeholder parsing

Wire /agents and /skills through the Rust command stack so they can run as direct CLI subcommands, direct slash invocations, and resume-safe slash commands. The handlers now provide structured usage output, skills discovery also covers legacy /commands markdown entries, and the reporting/tests line up more closely with the original TypeScript behavior where feasible.

Constraint: The Rust port does not yet have the original TypeScript TUI menus or plugin/MCP skill registry, so text reports approximate those views
Rejected: Rebuild the original interactive React menus in Rust now | too large for the current CLI parity slice
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep /skills discovery and the Skill tool aligned if command/skill registry parity expands later
Tested: cargo test --workspace
Tested: cargo clippy --workspace --all-targets -- -D warnings
Tested: cargo run -q -p rusty-claude-cli -- agents --help
Tested: cargo run -q -p rusty-claude-cli -- /agents
Not-tested: Live Anthropic-backed REPL execution of /agents or /skills

+At 4 AM on March 31, 2026, I woke up to my phone blowing up with notifications. The Claude Code source had been exposed, and the entire dev community was in a frenzy. My girlfriend in Korea was genuinely worried I might face legal action from Anthropic just for having the code on my machine — so I did what any engineer would do under pressure: I sat down, ported the core features to Python from scratch, and pushed it before the sun came up.
 
 The whole thing was orchestrated end-to-end using [oh-my-codex (OmX)](https://github.com/Yeachan-Heo/oh-my-codex) by [@bellman_ych](https://x.com/bellman_ych) — a workflow layer built on top of OpenAI's Codex ([@OpenAIDevs](https://x.com/OpenAIDevs)). I used `$team` mode for parallel code review and `$ralph` mode for persistent execution loops with architect-level verification. The entire porting session — from reading the original harness structure to producing a working Python tree with tests — was driven through OmX orchestration.
 
-The result is a clean-room Python rewrite that captures the architectural patterns of Claw Code's agent harness without copying any proprietary source. I'm now actively collaborating with [@bellman_ych](https://x.com/bellman_ych) — the creator of OmX himself — to push this further. The basic Python foundation is already in place and functional, but we're just getting started. **Stay tuned — a much more capable version is on the way.**

 I've been deeply interested in **harness engineering** — studying how agent systems wire tools, orchestrate tasks, and manage runtime context. This isn't a sudden thing. The Wall Street Journal featured my work earlier this month, documenting how I've been one of the most active power users exploring these systems:
 
-> AI startup worker Sigrid Jin, who attended the Seoul dinner, single-handedly used 25 billion of Claw Code tokens last year. At the time, usage limits were looser, allowing early enthusiasts to reach tens of billions of tokens at a very low cost.

+# TUI Enhancement Plan — Claw Code (`rusty-claude-cli`)
+
+## Executive Summary
+
+This plan covers a comprehensive analysis of the current terminal user interface and proposes phased enhancements that will transform the existing REPL/prompt CLI into a polished, modern TUI experience — while preserving the existing clean architecture and test coverage.
+
+---
+
+## 1. Current Architecture Analysis
+
+### Crate Map
+
+| Crate | Purpose | Lines | TUI Relevance |
+|---|---|---|---|
+| `rusty-claude-cli` | Main binary: REPL loop, arg parsing, rendering, API bridge | ~3,600 | **Primary TUI surface** |
+| `runtime` | Session, conversation loop, config, permissions, compaction | ~5,300 | Provides data/state |
+| `api` | Anthropic HTTP client + SSE streaming | ~1,500 | Provides stream events |
+| `commands` | Slash command metadata/parsing/help | ~470 | Drives command dispatch |
+| `tools` | 18 built-in tool implementations | ~3,500 | Tool execution display |
+
+### Current TUI Components
+
+| Component | File | What It Does Today | Quality |
+|---|---|---|---|
+| **Input** | `input.rs` (269 lines) | `rustyline`-based line editor with slash-command tab completion, Shift+Enter newline, history | ✅ Solid |
+| **Rendering** | `render.rs` (641 lines) | Markdown→terminal rendering (headings, lists, tables, code blocks with syntect highlighting, blockquotes), spinner widget | ✅ Good |
+| **App/REPL loop** | `main.rs` (3,159 lines) | The monolithic `LiveCli` struct: REPL loop, all slash command handlers, streaming output, tool call display, permission prompting, session management | ⚠️ Monolithic |
+| **Alt App** | `app.rs` (398 lines) | An earlier `CliApp` prototype with `ConversationClient`, stream event handling, `TerminalRenderer`, output format support | ⚠️ Appears unused/legacy |
+
+### Key Dependencies
+
+- **crossterm 0.28** — terminal control (cursor, colors, clear)
+- **pulldown-cmark 0.13** — Markdown parsing
+- **syntect 5** — syntax highlighting
+- **rustyline 15** — line editing with completion
+- **serde_json** — tool I/O formatting
+
+### Strengths
+
+1. **Clean rendering pipeline**: Markdown rendering is well-structured with state tracking, table rendering, code highlighting
+2. **Rich tool display**: Tool calls get box-drawing borders (`╭─ name ─╮`), results show ✓/✗ icons
+3. **Comprehensive slash commands**: 15 commands covering model switching, permissions, sessions, config, diff, export
+4. **Session management**: Full persistence, resume, list, switch, compaction
+5. **Permission prompting**: Interactive Y/N approval for restricted tool calls
+6. **Thorough tests**: Every formatting function, every parse path has unit tests
+
+### Weaknesses & Gaps
+
+1. **`main.rs` is a 3,159-line monolith** — all REPL logic, formatting, API bridging, session management, and tests in one file
+2. **No alternate-screen / full-screen layout** — everything is inline scrolling output
+3. **No progress bars** — only a single braille spinner; no indication of streaming progress or token counts during generation
+4. **No visual diff rendering** — `/diff` just dumps raw git diff text
+5. **No syntax highlighting in streamed output** — markdown rendering only applies to tool results, not to the main assistant response stream
+6. **No status bar / HUD** — model, tokens, session info not visible during interaction
+7. **No image/attachment preview** — `SendUserMessage` resolves attachments but never displays them
+8. **Streaming is char-by-char with artificial delay** — `stream_markdown` sleeps 8ms per whitespace-delimited chunk
+9. **No color theme customization** — hardcoded `ColorTheme::default()`
+10. **No resize handling** — no terminal size awareness for wrapping, truncation, or layout
+11. **Dual app structs** — `app.rs` has a separate `CliApp` that duplicates `LiveCli` from `main.rs`
+12. **No pager for long outputs** — `/status`, `/config`, `/memory` can overflow the viewport
+13. **Tool results not collapsible** — large bash outputs flood the screen
+14. **No thinking/reasoning indicator** — when the model is in "thinking" mode, no visual distinction
+15. **No auto-complete for tool arguments** — only slash command names complete
+
+---
+
+## 2. Enhancement Plan
+
+### Phase 0: Structural Cleanup (Foundation)
+
+**Goal**: Break the monolith, remove dead code, establish the module structure for TUI work.
+
+| Task | Description | Effort |
+|---|---|---|
+| 0.1 | **Extract `LiveCli` into `app.rs`** — Move the entire `LiveCli` struct, its impl, and helpers (`format_*`, `render_*`, session management) out of `main.rs` into focused modules: `app.rs` (core), `format.rs` (report formatting), `session_manager.rs` (session CRUD) | M |
+| 0.2 | **Remove or merge the legacy `CliApp`** — The existing `app.rs` has an unused `CliApp` with its own `ConversationClient`-based rendering. Either delete it or merge its unique features (stream event handler pattern) into the active `LiveCli` | S |
+| 0.3 | **Extract `main.rs` arg parsing** — The current `parse_args()` is a hand-rolled parser that duplicates the clap-based `args.rs`. Consolidate on the hand-rolled parser (it's more feature-complete) and move it to `args.rs`, or adopt clap fully | S |
+| 0.4 | **Create a `tui/` module** — Introduce `crates/rusty-claude-cli/src/tui/mod.rs` as the namespace for all new TUI components: `status_bar.rs`, `layout.rs`, `tool_panel.rs`, etc. | S |
+
+### Phase 1: Status Bar & Live HUD
+
+**Goal**: Persistent information display during interaction.
+
+| Task | Description | Effort |
+|---|---|---|
+| 1.1 | **Terminal-size-aware status line** — Use `crossterm::terminal::size()` to render a bottom-pinned status bar showing: model name, permission mode, session ID, cumulative token count, estimated cost | M |
+| 1.2 | **Live token counter** — Update the status bar in real-time as `AssistantEvent::Usage` and `AssistantEvent::TextDelta` events arrive during streaming | M |
+| 1.3 | **Turn duration timer** — Show elapsed time for the current turn (the `showTurnDuration` config already exists in Config tool but isn't wired up) | S |
+| 1.4 | **Git branch indicator** — Display the current git branch in the status bar (already parsed via `parse_git_status_metadata`) | S |
+
+### Phase 2: Enhanced Streaming Output
+
+**Goal**: Make the main response stream visually rich and responsive.
+
+| Task | Description | Effort |
+|---|---|---|
+| 2.1 | **Live markdown rendering** — Instead of raw text streaming, buffer text deltas and incrementally render Markdown as it arrives (heading detection, bold/italic, inline code). The existing `TerminalRenderer::render_markdown` can be adapted for incremental use | L |
+| 2.2 | **Thinking indicator** — When extended thinking/reasoning is active, show a distinct animated indicator (e.g., `🧠 Reasoning...` with pulsing dots or a different spinner) instead of the generic `🦀 Thinking...` | S |
+| 2.3 | **Streaming progress bar** — Add an optional horizontal progress indicator below the spinner showing approximate completion (based on max_tokens vs. output_tokens so far) | M |
+| 2.4 | **Remove artificial stream delay** — The current `stream_markdown` sleeps 8ms per chunk. For tool results this is fine, but for the main response stream it should be immediate or configurable | S |
+
+### Phase 3: Tool Call Visualization
+
+**Goal**: Make tool execution legible and navigable.
+
+| Task | Description | Effort |
+|---|---|---|
+| 3.1 | **Collapsible tool output** — For tool results longer than N lines (configurable, default 15), show a summary with `[+] Expand` hint; pressing a key reveals the full output. Initially implement as truncation with a "full output saved to file" fallback | M |
+| 3.2 | **Syntax-highlighted tool results** — When tool results contain code (detected by tool name — `bash` stdout, `read_file` content, `REPL` output), apply syntect highlighting rather than rendering as plain text | M |
+| 3.3 | **Tool call timeline** — For multi-tool turns, show a compact summary: `🔧 bash → ✓ | read_file → ✓ | edit_file → ✓ (3 tools, 1.2s)` after all tool calls complete | S |
+| 3.4 | **Diff-aware edit_file display** — When `edit_file` succeeds, show a colored unified diff of the change instead of just `✓ edit_file: path` | M |
+| 3.5 | **Permission prompt enhancement** — Style the approval prompt with box drawing, color the tool name, show a one-line summary of what the tool will do | S |
+
+### Phase 4: Enhanced Slash Commands & Navigation
+
+**Goal**: Improve information display and add missing features.
+
+| Task | Description | Effort |
+|---|---|---|
+| 4.1 | **Colored `/diff` output** — Parse the git diff and render it with red/green coloring for removals/additions, similar to `delta` or `diff-so-fancy` | M |
+| 4.2 | **Pager for long outputs** — When `/status`, `/config`, `/memory`, or `/diff` produce output longer than the terminal height, pipe through an internal pager (scroll with j/k/q) or external `$PAGER` | M |
+| 4.3 | **`/search` command** — Add a new command to search conversation history by keyword | M |
+| 4.4 | **`/undo` command** — Undo the last file edit by restoring from the `originalFile` data in `write_file`/`edit_file` tool results | M |
+| 4.5 | **Interactive session picker** — Replace the text-based `/session list` with an interactive fuzzy-filterable list (up/down arrows to select, enter to switch) | L |
+| 4.6 | **Tab completion for tool arguments** — Extend `SlashCommandHelper` to complete file paths after `/export`, model names after `/model`, session IDs after `/session switch` | M |
+
+### Phase 5: Color Themes & Configuration
+
+**Goal**: User-customizable visual appearance.
+
+| Task | Description | Effort |
+|---|---|---|
+| 5.1 | **Named color themes** — Add `dark` (current default), `light`, `solarized`, `catppuccin` themes. Wire to the existing `Config` tool's `theme` setting | M |
+| 5.2 | **ANSI-256 / truecolor detection** — Detect terminal capabilities and fall back gracefully (no colors → 16 colors → 256 → truecolor) | M |
+| 5.3 | **Configurable spinner style** — Allow choosing between braille dots, bar, moon phases, etc. | S |
+| 5.4 | **Banner customization** — Make the ASCII art banner optional or configurable via settings | S |
+
+### Phase 6: Full-Screen TUI Mode (Stretch)
+
+**Goal**: Optional alternate-screen layout for power users.
+
+| Task | Description | Effort |
+|---|---|---|
+| 6.1 | **Add `ratatui` dependency** — Introduce `ratatui` (terminal UI framework) as an optional dependency for the full-screen mode | S |
+| 6.2 | **Split-pane layout** — Top pane: conversation with scrollback; Bottom pane: input area; Right sidebar (optional): tool status/todo list | XL |
+| 6.3 | **Scrollable conversation view** — Navigate past messages with PgUp/PgDn, search within conversation | L |
+| 6.4 | **Keyboard shortcuts panel** — Show `?` help overlay with all keybindings | M |
+| 6.5 | **Mouse support** — Click to expand tool results, scroll conversation, select text for copy | L |
+
+---
+
+## 3. Priority Recommendation
+
+### Immediate (High Impact, Moderate Effort)
+
+1. **Phase 0** — Essential cleanup. The 3,159-line `main.rs` is the #1 maintenance risk and blocks clean TUI additions.
+2. **Phase 1.1–1.2** — Status bar with live tokens. Highest-impact UX win: users constantly want to know token usage.
+3. **Phase 2.4** — Remove artificial delay. Low effort, immediately noticeable improvement.
+4. **Phase 3.1** — Collapsible tool output. Large bash outputs currently wreck readability.
+
+### Near-Term (Next Sprint)
+
+5. **Phase 2.1** — Live markdown rendering. Makes the core interaction feel polished.
+6. **Phase 3.2** — Syntax-highlighted tool results.
+7. **Phase 3.4** — Diff-aware edit display.
+8. **Phase 4.1** — Colored diff for `/diff`.
+
+### Longer-Term
+
+9. **Phase 5** — Color themes (user demand-driven).
+10. **Phase 4.2–4.6** — Enhanced navigation and commands.
+11. **Phase 6** — Full-screen mode (major undertaking, evaluate after earlier phases ship).
+
+---
+
+## 4. Architecture Recommendations
+
+### Module Structure After Phase 0
+
+```
+crates/rusty-claude-cli/src/
+├── main.rs              # Entrypoint, arg dispatch only (~100 lines)
+├── args.rs              # CLI argument parsing (consolidate existing two parsers)
+├── app.rs               # LiveCli struct, REPL loop, turn execution
+├── format.rs            # All report formatting (status, cost, model, permissions, etc.)
+├── session_mgr.rs       # Session CRUD: create, resume, list, switch, persist
+├── init.rs              # Repo initialization (unchanged)
+├── input.rs             # Line editor (unchanged, minor extensions)
+├── render.rs            # TerminalRenderer, Spinner (extended)
+└── tui/
+    ├── mod.rs           # TUI module root
+    ├── status_bar.rs    # Persistent bottom status line
+    ├── tool_panel.rs    # Tool call visualization (boxes, timelines, collapsible)
+    ├── diff_view.rs     # Colored diff rendering
+    ├── pager.rs         # Internal pager for long outputs
+    └── theme.rs         # Color theme definitions and selection
+```
+
+### Key Design Principles
+
+1. **Keep the inline REPL as the default** — Full-screen TUI should be opt-in (`--tui` flag)
+2. **Everything testable without a terminal** — All formatting functions take `&mut impl Write`, never assume stdout directly
+3. **Streaming-first** — Rendering should work incrementally, not buffering the entire response
+4. **Respect `crossterm` for all terminal control** — Don't mix raw ANSI escape codes with crossterm (the current codebase does this in the startup banner)
+5. **Feature-gate heavy dependencies** — `ratatui` should be behind a `full-tui` feature flag
+
+---
+
+## 5. Risk Assessment
+
+| Risk | Mitigation |
+|---|---|
+| Breaking the working REPL during refactor | Phase 0 is pure restructuring with existing test coverage as safety net |
+| Terminal compatibility issues (tmux, SSH, Windows) | Rely on crossterm's abstraction; test in degraded environments |
+| Performance regression with rich rendering | Profile before/after; keep the fast path (raw streaming) always available |
+| Scope creep into Phase 6 | Ship Phases 0–3 as a coherent release before starting Phase 6 |
+| `app.rs` vs `main.rs` confusion | Phase 0.2 explicitly resolves this by removing the legacy `CliApp` |

+# TUI Enhancement Plan — Claw Code (`rusty-claude-cli`)
+
+## Executive Summary
+
+This plan covers a comprehensive analysis of the current terminal user interface and proposes phased enhancements that will transform the existing REPL/prompt CLI into a polished, modern TUI experience — while preserving the existing clean architecture and test coverage.
+
+---
+
+## 1. Current Architecture Analysis
+
+### Crate Map
+
+| Crate | Purpose | Lines | TUI Relevance |
+|---|---|---|---|
+| `rusty-claude-cli` | Main binary: REPL loop, arg parsing, rendering, API bridge | ~3,600 | **Primary TUI surface** |
+| `runtime` | Session, conversation loop, config, permissions, compaction | ~5,300 | Provides data/state |
+| `api` | Anthropic HTTP client + SSE streaming | ~1,500 | Provides stream events |
+| `commands` | Slash command metadata/parsing/help | ~470 | Drives command dispatch |
+| `tools` | 18 built-in tool implementations | ~3,500 | Tool execution display |
+
+### Current TUI Components
+
+| Component | File | What It Does Today | Quality |
+|---|---|---|---|
+| **Input** | `input.rs` (269 lines) | `rustyline`-based line editor with slash-command tab completion, Shift+Enter newline, history | ✅ Solid |
+| **Rendering** | `render.rs` (641 lines) | Markdown→terminal rendering (headings, lists, tables, code blocks with syntect highlighting, blockquotes), spinner widget | ✅ Good |
+| **App/REPL loop** | `main.rs` (3,159 lines) | The monolithic `LiveCli` struct: REPL loop, all slash command handlers, streaming output, tool call display, permission prompting, session management | ⚠️ Monolithic |
+| **Alt App** | `app.rs` (398 lines) | An earlier `CliApp` prototype with `ConversationClient`, stream event handling, `TerminalRenderer`, output format support | ⚠️ Appears unused/legacy |
+
+### Key Dependencies
+
+- **crossterm 0.28** — terminal control (cursor, colors, clear)
+- **pulldown-cmark 0.13** — Markdown parsing
+- **syntect 5** — syntax highlighting
+- **rustyline 15** — line editing with completion
+- **serde_json** — tool I/O formatting
+
+### Strengths
+
+1. **Clean rendering pipeline**: Markdown rendering is well-structured with state tracking, table rendering, code highlighting
+2. **Rich tool display**: Tool calls get box-drawing borders (`╭─ name ─╮`), results show ✓/✗ icons
+3. **Comprehensive slash commands**: 15 commands covering model switching, permissions, sessions, config, diff, export
+4. **Session management**: Full persistence, resume, list, switch, compaction
+5. **Permission prompting**: Interactive Y/N approval for restricted tool calls
+6. **Thorough tests**: Every formatting function, every parse path has unit tests
+
+### Weaknesses & Gaps
+
+1. **`main.rs` is a 3,159-line monolith** — all REPL logic, formatting, API bridging, session management, and tests in one file
+2. **No alternate-screen / full-screen layout** — everything is inline scrolling output
+3. **No progress bars** — only a single braille spinner; no indication of streaming progress or token counts during generation
+4. **No visual diff rendering** — `/diff` just dumps raw git diff text
+5. **No syntax highlighting in streamed output** — markdown rendering only applies to tool results, not to the main assistant response stream
+6. **No status bar / HUD** — model, tokens, session info not visible during interaction
+7. **No image/attachment preview** — `SendUserMessage` resolves attachments but never displays them
+8. **Streaming is char-by-char with artificial delay** — `stream_markdown` sleeps 8ms per whitespace-delimited chunk
+9. **No color theme customization** — hardcoded `ColorTheme::default()`
+10. **No resize handling** — no terminal size awareness for wrapping, truncation, or layout
+11. **Dual app structs** — `app.rs` has a separate `CliApp` that duplicates `LiveCli` from `main.rs`
+12. **No pager for long outputs** — `/status`, `/config`, `/memory` can overflow the viewport
+13. **Tool results not collapsible** — large bash outputs flood the screen
+14. **No thinking/reasoning indicator** — when the model is in "thinking" mode, no visual distinction
+15. **No auto-complete for tool arguments** — only slash command names complete
+
+---
+
+## 2. Enhancement Plan
+
+### Phase 0: Structural Cleanup (Foundation)
+
+**Goal**: Break the monolith, remove dead code, establish the module structure for TUI work.
+
+| Task | Description | Effort |
+|---|---|---|
+| 0.1 | **Extract `LiveCli` into `app.rs`** — Move the entire `LiveCli` struct, its impl, and helpers (`format_*`, `render_*`, session management) out of `main.rs` into focused modules: `app.rs` (core), `format.rs` (report formatting), `session_manager.rs` (session CRUD) | M |
+| 0.2 | **Remove or merge the legacy `CliApp`** — The existing `app.rs` has an unused `CliApp` with its own `ConversationClient`-based rendering. Either delete it or merge its unique features (stream event handler pattern) into the active `LiveCli` | S |
+| 0.3 | **Extract `main.rs` arg parsing** — The current `parse_args()` is a hand-rolled parser that duplicates the clap-based `args.rs`. Consolidate on the hand-rolled parser (it's more feature-complete) and move it to `args.rs`, or adopt clap fully | S |
+| 0.4 | **Create a `tui/` module** — Introduce `crates/rusty-claude-cli/src/tui/mod.rs` as the namespace for all new TUI components: `status_bar.rs`, `layout.rs`, `tool_panel.rs`, etc. | S |
+
+### Phase 1: Status Bar & Live HUD
+
+**Goal**: Persistent information display during interaction.
+
+| Task | Description | Effort |
+|---|---|---|
+| 1.1 | **Terminal-size-aware status line** — Use `crossterm::terminal::size()` to render a bottom-pinned status bar showing: model name, permission mode, session ID, cumulative token count, estimated cost | M |
+| 1.2 | **Live token counter** — Update the status bar in real-time as `AssistantEvent::Usage` and `AssistantEvent::TextDelta` events arrive during streaming | M |
+| 1.3 | **Turn duration timer** — Show elapsed time for the current turn (the `showTurnDuration` config already exists in Config tool but isn't wired up) | S |
+| 1.4 | **Git branch indicator** — Display the current git branch in the status bar (already parsed via `parse_git_status_metadata`) | S |
+
+### Phase 2: Enhanced Streaming Output
+
+**Goal**: Make the main response stream visually rich and responsive.
+
+| Task | Description | Effort |
+|---|---|---|
+| 2.1 | **Live markdown rendering** — Instead of raw text streaming, buffer text deltas and incrementally render Markdown as it arrives (heading detection, bold/italic, inline code). The existing `TerminalRenderer::render_markdown` can be adapted for incremental use | L |
+| 2.2 | **Thinking indicator** — When extended thinking/reasoning is active, show a distinct animated indicator (e.g., `🧠 Reasoning...` with pulsing dots or a different spinner) instead of the generic `🦀 Thinking...` | S |
+| 2.3 | **Streaming progress bar** — Add an optional horizontal progress indicator below the spinner showing approximate completion (based on max_tokens vs. output_tokens so far) | M |
+| 2.4 | **Remove artificial stream delay** — The current `stream_markdown` sleeps 8ms per chunk. For tool results this is fine, but for the main response stream it should be immediate or configurable | S |
+
+### Phase 3: Tool Call Visualization
+
+**Goal**: Make tool execution legible and navigable.
+
+| Task | Description | Effort |
+|---|---|---|
+| 3.1 | **Collapsible tool output** — For tool results longer than N lines (configurable, default 15), show a summary with `[+] Expand` hint; pressing a key reveals the full output. Initially implement as truncation with a "full output saved to file" fallback | M |
+| 3.2 | **Syntax-highlighted tool results** — When tool results contain code (detected by tool name — `bash` stdout, `read_file` content, `REPL` output), apply syntect highlighting rather than rendering as plain text | M |
+| 3.3 | **Tool call timeline** — For multi-tool turns, show a compact summary: `🔧 bash → ✓ | read_file → ✓ | edit_file → ✓ (3 tools, 1.2s)` after all tool calls complete | S |
+| 3.4 | **Diff-aware edit_file display** — When `edit_file` succeeds, show a colored unified diff of the change instead of just `✓ edit_file: path` | M |
+| 3.5 | **Permission prompt enhancement** — Style the approval prompt with box drawing, color the tool name, show a one-line summary of what the tool will do | S |
+
+### Phase 4: Enhanced Slash Commands & Navigation
+
+**Goal**: Improve information display and add missing features.
+
+| Task | Description | Effort |
+|---|---|---|
+| 4.1 | **Colored `/diff` output** — Parse the git diff and render it with red/green coloring for removals/additions, similar to `delta` or `diff-so-fancy` | M |
+| 4.2 | **Pager for long outputs** — When `/status`, `/config`, `/memory`, or `/diff` produce output longer than the terminal height, pipe through an internal pager (scroll with j/k/q) or external `$PAGER` | M |
+| 4.3 | **`/search` command** — Add a new command to search conversation history by keyword | M |
+| 4.4 | **`/undo` command** — Undo the last file edit by restoring from the `originalFile` data in `write_file`/`edit_file` tool results | M |
+| 4.5 | **Interactive session picker** — Replace the text-based `/session list` with an interactive fuzzy-filterable list (up/down arrows to select, enter to switch) | L |
+| 4.6 | **Tab completion for tool arguments** — Extend `SlashCommandHelper` to complete file paths after `/export`, model names after `/model`, session IDs after `/session switch` | M |
+
+### Phase 5: Color Themes & Configuration
+
+**Goal**: User-customizable visual appearance.
+
+| Task | Description | Effort |
+|---|---|---|
+| 5.1 | **Named color themes** — Add `dark` (current default), `light`, `solarized`, `catppuccin` themes. Wire to the existing `Config` tool's `theme` setting | M |
+| 5.2 | **ANSI-256 / truecolor detection** — Detect terminal capabilities and fall back gracefully (no colors → 16 colors → 256 → truecolor) | M |
+| 5.3 | **Configurable spinner style** — Allow choosing between braille dots, bar, moon phases, etc. | S |
+| 5.4 | **Banner customization** — Make the ASCII art banner optional or configurable via settings | S |
+
+### Phase 6: Full-Screen TUI Mode (Stretch)
+
+**Goal**: Optional alternate-screen layout for power users.
+
+| Task | Description | Effort |
+|---|---|---|
+| 6.1 | **Add `ratatui` dependency** — Introduce `ratatui` (terminal UI framework) as an optional dependency for the full-screen mode | S |
+| 6.2 | **Split-pane layout** — Top pane: conversation with scrollback; Bottom pane: input area; Right sidebar (optional): tool status/todo list | XL |
+| 6.3 | **Scrollable conversation view** — Navigate past messages with PgUp/PgDn, search within conversation | L |
+| 6.4 | **Keyboard shortcuts panel** — Show `?` help overlay with all keybindings | M |
+| 6.5 | **Mouse support** — Click to expand tool results, scroll conversation, select text for copy | L |
+
+---
+
+## 3. Priority Recommendation
+
+### Immediate (High Impact, Moderate Effort)
+
+1. **Phase 0** — Essential cleanup. The 3,159-line `main.rs` is the #1 maintenance risk and blocks clean TUI additions.
+2. **Phase 1.1–1.2** — Status bar with live tokens. Highest-impact UX win: users constantly want to know token usage.
+3. **Phase 2.4** — Remove artificial delay. Low effort, immediately noticeable improvement.
+4. **Phase 3.1** — Collapsible tool output. Large bash outputs currently wreck readability.
+
+### Near-Term (Next Sprint)
+
+5. **Phase 2.1** — Live markdown rendering. Makes the core interaction feel polished.
+6. **Phase 3.2** — Syntax-highlighted tool results.
+7. **Phase 3.4** — Diff-aware edit display.
+8. **Phase 4.1** — Colored diff for `/diff`.
+
+### Longer-Term
+
+9. **Phase 5** — Color themes (user demand-driven).
+10. **Phase 4.2–4.6** — Enhanced navigation and commands.
+11. **Phase 6** — Full-screen mode (major undertaking, evaluate after earlier phases ship).
+

+
+## 4. Architecture Recommendations
+
+### Module Structure After Phase 0
+
+```
+crates/rusty-claude-cli/src/
+├── main.rs              # Entrypoint, arg dispatch only (~100 lines)
+├── args.rs              # CLI argument parsing (consolidate existing two parsers)
+├── app.rs               # LiveCli struct, REPL loop, turn execution
+├── format.rs            # All report formatting (status, cost, model, permissions, etc.)
+├── session_mgr.rs       # Session CRUD: create, resume, list, switch, persist
+├── init.rs              # Repo initialization (unchanged)
+├── input.rs             # Line editor (unchanged, minor extensions)
+├── render.rs            # TerminalRenderer, Spinner (extended)
+└── tui/
+    ├── mod.rs           # TUI module root
+    ├── status_bar.rs    # Persistent bottom status line
+    ├── tool_panel.rs    # Tool call visualization (boxes, timelines, collapsible)
+    ├── diff_view.rs     # Colored diff rendering
+    ├── pager.rs         # Internal pager for long outputs
+    └── theme.rs         # Color theme definitions and selection
+```
+
+### Key Design Principles
+
+1. **Keep the inline REPL as the default** — Full-screen TUI should be opt-in (`--tui` flag)
+2. **Everything testable without a terminal** — All formatting functions take `&mut impl Write`, never assume stdout directly
+3. **Streaming-first** — Rendering should work incrementally, not buffering the entire response
+4. **Respect `crossterm` for all terminal control** — Don't mix raw ANSI escape codes with crossterm (the current codebase does this in the startup banner)
+5. **Feature-gate heavy dependencies** — `ratatui` should be behind a `full-tui` feature flag
+
+---
+
+## 5. Risk Assessment
+
+| Risk | Mitigation |
+|---|---|
+| Breaking the working REPL during refactor | Phase 0 is pure restructuring with existing test coverage as safety net |
+| Terminal compatibility issues (tmux, SSH, Windows) | Rely on crossterm's abstraction; test in degraded environments |
+| Performance regression with rich rendering | Profile before/after; keep the fast path (raw streaming) always available |
+| Scope creep into Phase 6 | Ship Phases 0–3 as a coherent release before starting Phase 6 |
+| `app.rs` vs `main.rs` confusion | Phase 0.2 explicitly resolves this by removing the legacy `CliApp` |
