2d09bf9961 Make sandbox isolation behavior explicit and inspectable
This adds a small runtime sandbox policy/status layer, threads
sandbox options through the bash tool, and exposes `/sandbox`
status reporting in the CLI. Linux namespace/network isolation
is best-effort and intentionally reported as requested vs active
so the feature does not overclaim guarantees on unsupported
hosts or nested container environments.

Constraint: No new dependencies for isolation support
Constraint: Must keep filesystem restriction claims honest unless hard mount isolation succeeds
Rejected: External sandbox/container wrapper | too heavy for this workspace and request
Rejected: Inline bash-only changes without shared status model | weaker testability and poorer CLI visibility
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Treat this as observable best-effort isolation, not a hard security boundary, unless stronger mount enforcement is added later
Tested: cargo fmt --all; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo test --workspace
Not-tested: Manual `/sandbox` REPL run on a real nested-container host

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Detected stack
- Languages: Rust.
- Frameworks: none detected from the supported starter markers.
## Verification
- Run Rust verification from `rust/`: `cargo fmt`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test --workspace`
- `src/` and `tests/` are both present; update both surfaces together when behavior changes.
## Repository shape
- `rust/` contains the Rust workspace and active CLI/runtime implementation.
- `src/` contains source files that should stay consistent with generated guidance and tests.
- `tests/` contains validation surfaces that should be reviewed alongside code changes.
## Working agreement
- Prefer small, reviewable changes and keep generated bootstrap files aligned with actual repo workflows.
- Keep shared defaults in `.claude.json`; reserve `.claude/settings.local.json` for machine-local overrides.
- Do not overwrite existing `CLAUDE.md` content automatically; update it intentionally when repo workflows change.

# PARITY GAP ANALYSIS
Scope: read-only comparison between the original TypeScript source at `/home/bellman/Workspace/claude-code/src/` and the Rust port under `rust/crates/`.
Method: compared feature surfaces, registries, entrypoints, and runtime plumbing only. No TypeScript source was copied.
## Executive summary
The Rust port has a good foundation for:
- Anthropic API/OAuth basics
- local conversation/session state
- a core tool loop
- MCP stdio/bootstrap support
- CLAUDE.md discovery
- a small but usable built-in tool set
It is **not feature-parity** with the TypeScript CLI.
Largest gaps:
- **plugins** are effectively absent in Rust
- **hooks** are parsed but not executed in Rust
- **CLI breadth** is much narrower in Rust
- **skills** are local-file only in Rust, without the TS registry/bundled pipeline
- **assistant orchestration** lacks TS hook-aware orchestration and remote/structured transports
- **services** beyond core API/OAuth/MCP are mostly missing in Rust
---
## tools/
### TS exists
Evidence:
- `src/tools/` contains broad tool families including `AgentTool`, `AskUserQuestionTool`, `BashTool`, `ConfigTool`, `FileReadTool`, `FileWriteTool`, `GlobTool`, `GrepTool`, `LSPTool`, `ListMcpResourcesTool`, `MCPTool`, `McpAuthTool`, `ReadMcpResourceTool`, `RemoteTriggerTool`, `ScheduleCronTool`, `SkillTool`, `Task*`, `Team*`, `TodoWriteTool`, `ToolSearchTool`, `WebFetchTool`, `WebSearchTool`.
- Tool execution/orchestration is split across `src/services/tools/StreamingToolExecutor.ts`, `src/services/tools/toolExecution.ts`, `src/services/tools/toolHooks.ts`, and `src/services/tools/toolOrchestration.ts`.
### Rust exists
Evidence:
- Tool registry is centralized in `rust/crates/tools/src/lib.rs` via `mvp_tool_specs()`.
- Current built-ins include shell/file/search/web/todo/skill/agent/config/notebook/repl/powershell primitives.
- Runtime execution is wired through `rust/crates/tools/src/lib.rs` and `rust/crates/runtime/src/conversation.rs`.
### Missing or broken in Rust
- No Rust equivalents for major TS tools such as `AskUserQuestionTool`, `LSPTool`, `ListMcpResourcesTool`, `MCPTool`, `McpAuthTool`, `ReadMcpResourceTool`, `RemoteTriggerTool`, `ScheduleCronTool`, `Task*`, `Team*`, and several workflow/system tools.
- Rust tool surface is still explicitly an MVP registry, not a parity registry.
- Rust lacks TSs layered tool orchestration split.
**Status:** partial core only.
---
## hooks/
### TS exists
Evidence:
- Hook command surface under `src/commands/hooks/`.
- Runtime hook machinery in `src/services/tools/toolHooks.ts` and `src/services/tools/toolExecution.ts`.
- TS supports `PreToolUse`, `PostToolUse`, and broader hook-driven behaviors configured through settings and documented in `src/skills/bundled/updateConfig.ts`.
### Rust exists
Evidence:
- Hook config is parsed and merged in `rust/crates/runtime/src/config.rs`.
- Hook config can be inspected via Rust config reporting in `rust/crates/commands/src/lib.rs` and `rust/crates/rusty-claude-cli/src/main.rs`.
- Prompt guidance mentions hooks in `rust/crates/runtime/src/prompt.rs`.
### Missing or broken in Rust
- No actual hook execution pipeline in `rust/crates/runtime/src/conversation.rs`.
- No PreToolUse/PostToolUse mutation/deny/rewrite/result-hook behavior.
- No Rust `/hooks` parity command.
**Status:** config-only; runtime behavior missing.
---
## plugins/
### TS exists
Evidence:
- Built-in plugin scaffolding in `src/plugins/builtinPlugins.ts` and `src/plugins/bundled/index.ts`.
- Plugin lifecycle/services in `src/services/plugins/PluginInstallationManager.ts` and `src/services/plugins/pluginOperations.ts`.
- CLI/plugin command surface under `src/commands/plugin/` and `src/commands/reload-plugins/`.
### Rust exists
Evidence:
- No dedicated plugin subsystem appears under `rust/crates/`.
- Repo-wide Rust references to plugins are effectively absent beyond text/help mentions.
### Missing or broken in Rust
- No plugin loader.
- No marketplace install/update/enable/disable flow.
- No `/plugin` or `/reload-plugins` parity.
- No plugin-provided hook/tool/command/MCP extension path.
**Status:** missing.
---
## skills/ and CLAUDE.md discovery
### TS exists
Evidence:
- Skill loading/registry pipeline in `src/skills/loadSkillsDir.ts`, `src/skills/bundledSkills.ts`, and `src/skills/mcpSkillBuilders.ts`.
- Bundled skills under `src/skills/bundled/`.
- Skills command surface under `src/commands/skills/`.
### Rust exists
Evidence:
- `Skill` tool in `rust/crates/tools/src/lib.rs` resolves and reads local `SKILL.md` files.
- CLAUDE.md discovery is implemented in `rust/crates/runtime/src/prompt.rs`.
- Rust supports `/memory` and `/init` via `rust/crates/commands/src/lib.rs` and `rust/crates/rusty-claude-cli/src/main.rs`.
### Missing or broken in Rust
- No bundled skill registry equivalent.
- No `/skills` command.
- No MCP skill-builder pipeline.
- No TS-style live skill discovery/reload/change handling.
- No comparable session-memory / team-memory integration around skills.
**Status:** basic local skill loading only.
---
## cli/
### TS exists
Evidence:
- Large command surface under `src/commands/` including `agents`, `hooks`, `mcp`, `memory`, `model`, `permissions`, `plan`, `plugin`, `resume`, `review`, `skills`, `tasks`, and many more.
- Structured/remote transport stack in `src/cli/structuredIO.ts`, `src/cli/remoteIO.ts`, and `src/cli/transports/*`.
- CLI handler split in `src/cli/handlers/*`.
### Rust exists
Evidence:
- Shared slash command registry in `rust/crates/commands/src/lib.rs`.
- Rust slash commands currently cover `help`, `status`, `compact`, `model`, `permissions`, `clear`, `cost`, `resume`, `config`, `memory`, `init`, `diff`, `version`, `export`, `session`.
- Main CLI/repl/prompt handling lives in `rust/crates/rusty-claude-cli/src/main.rs`.
### Missing or broken in Rust
- Missing major TS command families: `/agents`, `/hooks`, `/mcp`, `/plugin`, `/skills`, `/plan`, `/review`, `/tasks`, and many others.
- No Rust equivalent to TS structured IO / remote transport layers.
- No TS-style handler decomposition for auth/plugins/MCP/agents.
- JSON prompt mode is improved on this branch, but still not clean transport parity: empirical verification shows tool-capable JSON output can emit human-readable tool-result lines before the final JSON object.
**Status:** functional local CLI core, much narrower than TS.
---
## assistant/ (agentic loop, streaming, tool calling)
### TS exists
Evidence:
- Assistant/session surface at `src/assistant/sessionHistory.ts`.
- Tool orchestration in `src/services/tools/StreamingToolExecutor.ts`, `src/services/tools/toolExecution.ts`, `src/services/tools/toolOrchestration.ts`.
- Remote/structured streaming layers in `src/cli/structuredIO.ts` and `src/cli/remoteIO.ts`.
### Rust exists
Evidence:
- Core loop in `rust/crates/runtime/src/conversation.rs`.
- Stream/tool event translation in `rust/crates/rusty-claude-cli/src/main.rs`.
- Session persistence in `rust/crates/runtime/src/session.rs`.
### Missing or broken in Rust
- No TS-style hook-aware orchestration layer.
- No TS structured/remote assistant transport stack.
- No richer TS assistant/session-history/background-task integration.
- JSON output path is no longer single-turn only on this branch, but output cleanliness still lags TS transport expectations.
**Status:** strong core loop, missing orchestration layers.
---
## services/ (API client, auth, models, MCP)
### TS exists
Evidence:
- API services under `src/services/api/*`.
- OAuth services under `src/services/oauth/*`.
- MCP services under `src/services/mcp/*`.
- Additional service layers for analytics, prompt suggestion, session memory, plugin operations, settings sync, policy limits, team memory sync, notifier, voice, and more under `src/services/*`.
### Rust exists
Evidence:
- Core Anthropic API client in `rust/crates/api/src/{client,error,sse,types}.rs`.
- OAuth support in `rust/crates/runtime/src/oauth.rs`.
- MCP config/bootstrap/client support in `rust/crates/runtime/src/{config,mcp,mcp_client,mcp_stdio}.rs`.
- Usage accounting in `rust/crates/runtime/src/usage.rs`.
- Remote upstream-proxy support in `rust/crates/runtime/src/remote.rs`.
### Missing or broken in Rust
- Most TS service ecosystem beyond core messaging/auth/MCP is absent.
- No TS-equivalent plugin service layer.
- No TS-equivalent analytics/settings-sync/policy-limit/team-memory subsystems.
- No TS-style MCP connection-manager/UI layer.
- Model/provider ergonomics remain thinner than TS.
**Status:** core foundation exists; broader service ecosystem missing.
---
## Critical bug status in this worktree
### Fixed
- **Prompt mode tools enabled**
- `rust/crates/rusty-claude-cli/src/main.rs` now constructs prompt mode with `LiveCli::new(model, true, ...)`.
- **Default permission mode = DangerFullAccess**
- Runtime default now resolves to `DangerFullAccess` in `rust/crates/rusty-claude-cli/src/main.rs`.
- Clap default also uses `DangerFullAccess` in `rust/crates/rusty-claude-cli/src/args.rs`.
- Init template writes `dontAsk` in `rust/crates/rusty-claude-cli/src/init.rs`.
- **Streaming `{}` tool-input prefix bug**
- `rust/crates/rusty-claude-cli/src/main.rs` now strips the initial empty object only for streaming tool input, while preserving legitimate `{}` in non-stream responses.
- **Unlimited max_iterations**
- Verified at `rust/crates/runtime/src/conversation.rs` with `usize::MAX`.
### Remaining notable parity issue
- **JSON prompt output cleanliness**
- Tool-capable JSON mode now loops, but empirical verification still shows pre-JSON human-readable tool-result output when tools fire.

# 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 1.11.2** — 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 4.24.6** — 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 03 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` |

### Crate Responsibilities
## Prerequisites
- **api** — HTTP client, SSE stream parser, request/response types, auth (API key + OAuth bearer)
- **commands** — Slash command definitions and help text generation
- **compat-harness** — Extracts tool/prompt manifests from upstream TS source
- **runtime** — `ConversationRuntime` agentic loop, `ConfigLoader` hierarchy, `Session` persistence, permission policy, MCP client, system prompt assembly, usage tracking
- **rusty-claude-cli** — REPL, one-shot prompt, streaming display, tool call rendering, CLI argument parsing
- **tools** — Tool specs + execution: Bash, ReadFile, WriteFile, EditFile, GlobSearch, GrepSearch, WebSearch, WebFetch, Agent, TodoWrite, NotebookEdit, Skill, ToolSearch, REPL runtimes
- Rust toolchain installed (`rustup`, stable toolchain)
- Network access and Anthropic credentials for live prompt/REPL usage
## Stats
## Build
- **~20K lines** of Rust
- **6 crates** in workspace
- **Binary name:** `claw`
- **Default model:** `claude-opus-4-6`
- **Default permissions:** `danger-full-access`
From the repository root:
## License
```bash
cd rust
cargo build --release -p rusty-claude-cli
```
See repository root.
The optimized binary will be written to:
```bash
./target/release/rusty-claude-cli
```
## Test
Run the verified workspace test suite used for release-readiness:
```bash
cd rust
cargo test --workspace --exclude compat-harness
```
## Quick start
### Show help
```bash
cd rust
cargo run -p rusty-claude-cli -- --help
```
### Print version
```bash
cd rust
cargo run -p rusty-claude-cli -- --version
```
### Login with OAuth
Configure `settings.json` with an `oauth` block containing `clientId`, `authorizeUrl`, `tokenUrl`, optional `callbackPort`, and optional `scopes`, then run:
```bash
cd rust
cargo run -p rusty-claude-cli -- login
```
This opens the browser, listens on the configured localhost callback, exchanges the auth code for tokens, and stores OAuth credentials in `~/.claude/credentials.json` (or `$CLAUDE_CONFIG_HOME/credentials.json`).
### Logout
```bash
cd rust
cargo run -p rusty-claude-cli -- logout
```
This removes only the stored OAuth credentials and preserves unrelated JSON fields in `credentials.json`.
## Usage examples
### 1) Prompt mode
Send one prompt, stream the answer, then exit:
```bash
cd rust
cargo run -p rusty-claude-cli -- prompt "Summarize the architecture of this repository"
```
Use a specific model:
```bash
cd rust
cargo run -p rusty-claude-cli -- --model claude-sonnet-4-20250514 prompt "List the key crates in this workspace"
```
Restrict enabled tools in an interactive session:
```bash
cd rust
cargo run -p rusty-claude-cli -- --allowedTools read,glob
```
### 2) REPL mode
Start the interactive shell:
```bash
cd rust
cargo run -p rusty-claude-cli --
```
Inside the REPL, useful commands include:
```text
/help
/status
/model claude-sonnet-4-20250514
/permissions workspace-write
/cost
/compact
/memory
/config
/init
/diff
/version
/export notes.txt
/session list
/exit
```
### 3) Resume an existing session
Inspect or maintain a saved session file without entering the REPL:
```bash
cd rust
cargo run -p rusty-claude-cli -- --resume session.json /status /compact /cost
```
You can also inspect memory/config state for a restored session:
```bash
cd rust
cargo run -p rusty-claude-cli -- --resume session.json /memory /config
```
## Available commands
### Top-level CLI commands
- `prompt <text...>` — run one prompt non-interactively
- `--resume <session.json> [/commands...]` — inspect or maintain a saved session
- `dump-manifests` — print extracted upstream manifest counts
- `bootstrap-plan` — print the current bootstrap skeleton
- `system-prompt [--cwd PATH] [--date YYYY-MM-DD]` — render the synthesized system prompt
- `--help` / `-h` — show CLI help
- `--version` / `-V` — print the CLI version and build info locally (no API call)
- `--output-format text|json` — choose non-interactive prompt output rendering
- `--allowedTools <tool[,tool...]>` — restrict enabled tools for interactive sessions and prompt-mode tool use
### Interactive slash commands
- `/help` — show command help
- `/status` — show current session status
- `/compact` — compact local session history
- `/model [model]` — inspect or switch the active model
- `/permissions [read-only|workspace-write|danger-full-access]` — inspect or switch permissions
- `/clear [--confirm]` — clear the current local session
- `/cost` — show token usage totals
- `/resume <session-path>` — load a saved session into the REPL
- `/config [env|hooks|model]` — inspect discovered Claude config
- `/memory` — inspect loaded instruction memory files
- `/init` — create a starter `CLAUDE.md`
- `/diff` — show the current git diff for the workspace
- `/version` — print version and build metadata locally
- `/export [file]` — export the current conversation transcript
- `/session [list|switch <session-id>]` — inspect or switch managed local sessions
- `/exit` — leave the REPL
## Environment variables
### Anthropic/API
- `ANTHROPIC_API_KEY` — highest-precedence API credential
- `ANTHROPIC_AUTH_TOKEN` — bearer-token override used when no API key is set
- Persisted OAuth credentials in `~/.claude/credentials.json` — used when neither env var is set
- `ANTHROPIC_BASE_URL` — override the Anthropic API base URL
- `ANTHROPIC_MODEL` — default model used by selected live integration tests
### CLI/runtime
- `RUSTY_CLAUDE_PERMISSION_MODE` — default REPL permission mode (`read-only`, `workspace-write`, or `danger-full-access`)
- `CLAUDE_CONFIG_HOME` — override Claude config discovery root
- `CLAUDE_CODE_REMOTE` — enable remote-session bootstrap handling when supported
- `CLAUDE_CODE_REMOTE_SESSION_ID` — remote session identifier when using remote mode
- `CLAUDE_CODE_UPSTREAM` — override the upstream TS source path for compat-harness extraction
- `CLAWD_WEB_SEARCH_BASE_URL` — override the built-in web search service endpoint used by tooling
## Notes
- `compat-harness` exists to compare the Rust port against the upstream TypeScript codebase and is intentionally excluded from the requested release test run.
- The CLI currently focuses on a practical integrated workflow: prompt execution, REPL operation, session inspection/resume, config discovery, and tool/runtime plumbing.

# 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 1.11.2** — 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 4.24.6** — 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 03 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` |
