auto: save WIP progress from rcc session

Tighten prompt-mode parity for the Rust CLI by enabling native tools in one-shot runs, defaulting fresh sessions to danger-full-access, and documenting the remaining TS-vs-Rust gaps.

The JSON prompt path now runs through the full conversation loop so tool use and tool results are preserved without streaming terminal noise, while the tool-input accumulator keeps the streaming {} placeholder fix without corrupting legitimate non-stream empty objects.

Constraint: Original TypeScript source was treated as read-only for parity analysis
Constraint: No new dependencies; keep the fix localized to the Rust port
Rejected: Leave JSON prompt mode on a direct non-tool API path | preserved the one-shot parity bug
Rejected: Keep workspace-write as the default permission mode | contradicted requested parity target
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep prompt text and prompt JSON paths on the same tool-capable runtime semantics unless upstream behavior proves they must diverge
Tested: cargo build --release; cargo test
Not-tested: live remote prompt run against LayoffLabs endpoint in this session

+# PARITY Gap Analysis
+
+Date: 2026-04-01
+
+Scope compared:
+- Upstream TypeScript: `/home/bellman/Workspace/claude-code/src/`
+- Rust port: `rust/crates/`
+
+Method:
+- Read-only comparison only.
+- No upstream source was copied into this repo.
+- This is a focused feature-gap report for `tools`, `hooks`, `plugins`, `skills`, `cli`, `assistant`, and `services`.
+
+## Executive summary
+
+The Rust port has a solid core for:
+- basic prompt/REPL flow
+- session/runtime state
+- Anthropic API/OAuth plumbing
+- a compact MVP tool registry
+- CLAUDE.md discovery
+- MCP config parsing/bootstrap primitives
+
+But it is still materially behind the TypeScript implementation in six major areas:
+1. **Tools surface area** is much smaller.
+2. **Hook execution** is largely missing; Rust mostly loads hook config but does not run a TS-style PreToolUse/PostToolUse pipeline.
+3. **Plugins** are effectively absent in Rust.
+4. **Skills** are only partially implemented in Rust via direct `SKILL.md` loading; there is no comparable skills command/discovery/registration surface.
+5. **CLI** breadth is much narrower in Rust.
+6. **Assistant/tool orchestration** lacks the richer streaming concurrency, hook integration, and orchestration behavior present in TS.
+7. **Services** in Rust cover API/auth/runtime basics, but many higher-level TS services are missing.
+
+## Critical bug status on this branch
+
+Targeted critical items requested by the user:
+- **Prompt mode tools enabled**: fixed in `rust/crates/rusty-claude-cli/src/main.rs:75-82`
+- **Default permission mode = danger-full-access**: fixed in `rust/crates/rusty-claude-cli/src/args.rs:12-16`, `rust/crates/rusty-claude-cli/src/main.rs:348-353`, and starter config `rust/crates/rusty-claude-cli/src/init.rs:4-9`
+- **Tool input `{}` prefix bug**: fixed/guarded in streaming vs non-stream paths at `rust/crates/rusty-claude-cli/src/main.rs:2211-2256`
+- **Unlimited max_iterations**: already present at `rust/crates/runtime/src/conversation.rs:143-148` with `usize::MAX` initialization at `rust/crates/runtime/src/conversation.rs:119`
+
+Build/test/manual verification is tracked separately below and must pass before the branch is considered done.
+
+---
+
+## 1) tools/
+
+### Upstream TS has
+- Large per-tool module surface under `src/tools/`, including agent/task tools, AskUserQuestion, MCP tools, plan/worktree tools, REPL, schedule/task tools, synthetic output, brief/upload, and more.
+- Evidence:
+  - `src/tools/AgentTool/AgentTool.tsx`
+  - `src/tools/AskUserQuestionTool/AskUserQuestionTool.tsx`
+  - `src/tools/ListMcpResourcesTool/ListMcpResourcesTool.ts`
+  - `src/tools/ReadMcpResourceTool/ReadMcpResourceTool.ts`
+  - `src/tools/EnterPlanModeTool/EnterPlanModeTool.ts`
+  - `src/tools/ExitPlanModeTool/ExitPlanModeV2Tool.ts`
+  - `src/tools/EnterWorktreeTool/EnterWorktreeTool.ts`
+  - `src/tools/ExitWorktreeTool/ExitWorktreeTool.ts`
+  - `src/tools/RemoteTriggerTool/RemoteTriggerTool.ts`
+  - `src/tools/ScheduleCronTool/*`
+  - `src/tools/TaskCreateTool/*`, `TaskGetTool/*`, `TaskListTool/*`, `TaskOutputTool/*`
+
+### Rust currently has
+- A single MVP registry in `rust/crates/tools/src/lib.rs:53-371`.
+- Implemented tools include `bash`, `read_file`, `write_file`, `edit_file`, `glob_search`, `grep_search`, `WebFetch`, `WebSearch`, `TodoWrite`, `Skill`, `Agent`, `ToolSearch`, `NotebookEdit`, `Sleep`, `SendUserMessage`, `Config`, `StructuredOutput`, `REPL`, `PowerShell`.
+
+### Missing or broken in Rust
+- **Missing large chunks of the upstream tool catalog**: I did not find Rust equivalents for AskUserQuestion, MCP resource listing/reading tools, plan/worktree entry/exit tools, task management tools, remote trigger, synthetic output, or schedule/cron tools.
+- **Tool decomposition is much coarser**: TS isolates tool-specific validation/security/UI behavior per tool module; Rust centralizes almost everything in one file (`rust/crates/tools/src/lib.rs`).
+- **Likely parity impact**: lower fidelity tool prompting, weaker per-tool behavior specialization, and fewer native tool choices exposed to the model.
+
+---
+
+## 2) hooks/
+
+### Upstream TS has
+- A full permission and tool-hook system with **PermissionRequest**, **PreToolUse**, **PostToolUse**, and failure/cancellation handling.
+- Evidence:
+  - `src/hooks/toolPermission/PermissionContext.ts:25,222`
+  - `src/hooks/toolPermission/handlers/coordinatorHandler.ts:32-38`
+  - `src/hooks/toolPermission/handlers/interactiveHandler.ts:412-429`
+  - `src/services/tools/toolHooks.ts:39,435`
+  - `src/services/tools/toolExecution.ts:800,1074,1483`
+  - `src/commands/hooks/index.ts:5-8`
+
+### Rust currently has
+- Hook data is **loaded/merged from config** and visible in reports:
+  - `rust/crates/runtime/src/config.rs:786-797,829-838`
+  - `rust/crates/rusty-claude-cli/src/main.rs:1665-1669`
+- The system prompt acknowledges user-configured hooks:
+  - `rust/crates/runtime/src/prompt.rs:452-459`
+
+### Missing or broken in Rust
+- **No comparable hook execution pipeline found** in the Rust runtime conversation/tool execution path.
+- `rust/crates/runtime/src/conversation.rs:151-208` goes straight from assistant tool_use -> permission check -> tool execute -> tool_result, without TS-style PreToolUse/PostToolUse processing.
+- I did **not** find Rust counterparts to TS files like `toolHooks.ts` or `PermissionContext.ts` that execute hook callbacks and alter/block tool behavior.
+- Result: Rust appears to support **hook configuration visibility**, but not full **hook behavior parity**.
+
+---
+
+## 3) plugins/
+
+### Upstream TS has
+- Built-in and bundled plugin registration plus CLI/service support for validate/list/install/uninstall/enable/disable/update flows.
+- Evidence:
+  - `src/plugins/builtinPlugins.ts:7-17,149-150`
+  - `src/plugins/bundled/index.ts:7-22`
+  - `src/cli/handlers/plugins.ts:51,101,157,668`
+  - `src/services/plugins/pluginOperations.ts:16,54,306,435,713`
+  - `src/services/plugins/pluginCliCommands.ts:7,36`
+
+### Rust currently has
+- I did **not** find a dedicated plugin crate/module/handler under `rust/crates/`.
+- The Rust crate layout is only `api`, `commands`, `compat-harness`, `runtime`, `rusty-claude-cli`, and `tools`.
+
+### Missing or broken in Rust
+- **Plugin loading/install/update/validation is missing.**
+- **No plugin CLI surface found** comparable to `claude plugin ...`.
+- **No plugin runtime refresh/reconciliation layer found**.
+- This is one of the largest parity gaps.
+
+---
+
+## 4) skills/
+
+### Upstream TS has
+- Bundled skills registry and loader integration, plus a `skills` command.
+- Evidence:
+  - `src/commands/skills/index.ts:6`
+  - `src/skills/bundledSkills.ts:44,99,107,114`
+  - `src/skills/loadSkillsDir.ts:65`
+  - `src/skills/mcpSkillBuilders.ts:4-21,40`
+
+### Rust currently has
+- A `Skill` tool that loads local `SKILL.md` files directly:
+  - `rust/crates/tools/src/lib.rs:1244-1255`
+  - `rust/crates/tools/src/lib.rs:1288-1323`
+- CLAUDE.md / instruction discovery exists in runtime prompt loading:
+  - `rust/crates/runtime/src/prompt.rs:203-208`
+
+### Missing or broken in Rust
+- **No Rust `/skills` slash command** in `rust/crates/commands/src/lib.rs:41-166`.
+- **No visible bundled-skill registry equivalent** to TS `bundledSkills.ts` / `loadSkillsDir.ts` / `mcpSkillBuilders.ts`.
+- Current Rust skill support is closer to **direct file loading** than full upstream **skill discovery/registration/command integration**.
+
+---
+
+## 5) cli/
+
+### Upstream TS has
+- Broad CLI handler and transport surface.
+- Evidence:
+  - `src/cli/handlers/agents.ts:2-32`
+  - `src/cli/handlers/auth.ts`
+  - `src/cli/handlers/autoMode.ts:24,35,73`
+  - `src/cli/handlers/plugins.ts:2-3,101,157,668`
+  - `src/cli/remoteIO.ts:25-35,118-127`
+  - `src/cli/transports/SSETransport.ts`
+  - `src/cli/transports/WebSocketTransport.ts`
+  - `src/cli/transports/HybridTransport.ts`
+  - `src/cli/transports/SerialBatchEventUploader.ts`
+  - `src/cli/transports/WorkerStateUploader.ts`
+
+### Rust currently has
+- Minimal top-level subcommands in `rust/crates/rusty-claude-cli/src/args.rs:29-39` and `rust/crates/rusty-claude-cli/src/main.rs:67-90,242-261`.
+- Slash command surface is 15 commands total in `rust/crates/commands/src/lib.rs:41-166,389`.
+
+### Missing or broken in Rust
+- **Missing major CLI subcommand families**: agents, plugins, mcp management, auto-mode tooling, and many other TS commands.
+- **Missing remote/transport stack parity**: I did not find Rust equivalents to TS remote structured IO / SSE / websocket / CCR transport layers.
+- **Slash command breadth is much narrower** than TS command inventory under `src/commands/`.
+- **Prompt-mode parity bug** was present and is now fixed for this branch’s prompt path.
+
+---
+
+## 6) assistant/
+
+### Upstream TS has
+- Rich tool orchestration and streaming execution behavior, including concurrency/cancellation/fallback logic.
+- Evidence:
+  - `src/services/tools/StreamingToolExecutor.ts:35-214`
+  - `src/services/tools/toolExecution.ts:455-569,800-918,1483`
+  - `src/services/tools/toolOrchestration.ts:134-167`
+  - `src/assistant/sessionHistory.ts`
+
+### Rust currently has
+- A straightforward agentic loop in `rust/crates/runtime/src/conversation.rs:130-214`.
+- Streaming API adaptation in `rust/crates/rusty-claude-cli/src/main.rs:1998-2058`.
+- Tool-use block assembly and non-stream fallback handling in `rust/crates/rusty-claude-cli/src/main.rs:2211-2256`.
+
+### Missing or broken in Rust
+- **No TS-style streaming tool executor** with sibling cancellation / fallback discard semantics.
+- **No integrated PreToolUse/PostToolUse hook participation** in assistant execution.
+- **No comparable orchestration layer for richer tool event semantics** found.
+- Historically broken parity items in prompt mode were:
+  - prompt tool enablement (`main.rs:75-82`) — now fixed on this branch
+  - streamed `{}` tool-input prefix behavior (`main.rs:2211-2256`) — now fixed/guarded on this branch
+
+---
+
+## 7) services/
+
+### Upstream TS has
+- Very broad service layer, including API, analytics, compact/session memory, prompt suggestions, plugin services, MCP service helpers, LSP management, policy limits, team memory sync, notifier/tips, etc.
+- Evidence:
+  - `src/services/api/client.ts`, `src/services/api/claude.ts`, `src/services/api/withRetry.ts`
+  - `src/services/oauth/client.ts`, `src/services/oauth/index.ts`
+  - `src/services/mcp/*`
+  - `src/services/plugins/*`
+  - `src/services/lsp/*`
+  - `src/services/compact/*`
+  - `src/services/SessionMemory/*`
+  - `src/services/PromptSuggestion/*`
+  - `src/services/analytics/*`
+  - `src/services/teamMemorySync/*`
+
+### Rust currently has
+- Core service equivalents for:
+  - API client + SSE: `rust/crates/api/src/client.rs`, `rust/crates/api/src/sse.rs`, `rust/crates/api/src/types.rs`
+  - OAuth: `rust/crates/runtime/src/oauth.rs`
+  - MCP config/bootstrap primitives: `rust/crates/runtime/src/mcp.rs`, `rust/crates/runtime/src/mcp_client.rs`, `rust/crates/runtime/src/mcp_stdio.rs`, `rust/crates/runtime/src/config.rs`
+  - prompt/context loading: `rust/crates/runtime/src/prompt.rs`
+  - session compaction/runtime usage: `rust/crates/runtime/src/compact.rs`, `rust/crates/runtime/src/usage.rs`
+
+### Missing or broken in Rust
+- **Missing many higher-level services**: analytics, plugin services, prompt suggestion, team memory sync, richer LSP service management, notifier/tips ecosystem, and much of the surrounding product/service scaffolding.
+- Rust is closer to a **runtime/API core** than a full parity implementation of the TS service layer.
+
+---
+
+## Highest-priority parity gaps after the critical bug fixes
+
+1. **Hook execution parity**
+   - Config exists, execution does not appear to.
+   - This affects permissions, tool interception, and continuation behavior.
+
+2. **Plugin system parity**
+   - Entire install/load/manage surface appears missing.
+
+3. **CLI breadth parity**
+   - Missing many upstream command families and remote transports.
+
+4. **Tool surface parity**
+   - MVP tool registry exists, but a large number of upstream tool types are absent.
+
+5. **Assistant orchestration parity**
+   - Core loop exists, but advanced streaming/execution behaviors from TS are missing.
+
+## Recommended next work after current critical fixes
+
+1. Finish build/test/manual verification of the critical bug patch.
+2. Implement **hook execution** before broadening the tool surface further.
+3. Decide whether **plugins** are in-scope for parity; if yes, this likely needs dedicated design work, not a small patch.
+4. Expand the CLI/tool matrix deliberately rather than adding one-off commands without shared orchestration support.
