fix(clippy): resolve new lint violations in trident, compact, and claw-rag-service

- runtime/trident.rs: derive Default, fix for_kv_map, if_same_then_else, extend_with_drain, unnecessary_cast, needless_borrows - runtime/compact.rs: fix useless_borrows_in_formatting - claw-rag-service/ingest.rs: remove unnecessary into_iter() - claw-rag-service/db.rs: use as_chunks instead of chunks_exact, remove unused import All tests pass (1014 Rust + 47 Python tests verified).
fix(cli): order parallel tool results by call index and cap fan-out

+# Multi-Tool Execution & Sub-Agent Delegation
+
+Two complementary features that dramatically reduce latency and token usage when the model needs to perform multiple operations or gather context.
+
+## Feature 1: Parallel Tool Execution
+
+When the model returns multiple tool_use blocks in a single response, read-only tools now execute concurrently instead of sequentially.
+
+### How it works
+
+The `run_turn` loop is refactored into 3 phases:
+
+1. **Pre-hooks + permission checks** (sequential — hooks may mutate state)
+2. **Tool execution** (batch — parallel for read-only tools via `std::thread::scope`)
+3. **Post-hooks + session updates** (sequential — preserves original ordering)
+
+### Parallel-safe tools
+
+These tools are safe to run concurrently because they only read state and dispatch through the stateless tool registry:
+
+- `read_file`, `glob_search`, `grep_search`
+- `WebFetch`, `WebSearch`
+- `ToolSearch`, `Skill`
+- `LSP`
+- `GitStatus`, `GitDiff`, `GitLog`, `GitShow`, `GitBlame`
+
+### Sequential-only tools
+
+Tools that require `&mut self` or have side effects continue to run one at a time:
+
+- `bash`, `write_file`, `edit_file` (side effects)
+- `MCP`, `McpAuth`, `RemoteTrigger` (network state)
+- `Agent`, `TaskCreate`, `WorkerCreate` (stateful)
+- `NotebookEdit`, `REPL`, `PowerShell` (side effects)
+
+### Safety guarantees
+
+- Pre/post hooks always run sequentially
+- Permission checks complete before any tool executes
+- Tool results are pushed to the session in the original model order
+- Falls back to sequential for single-tool batches
+- Thread scopes ensure all parallel work completes before `execute_batch` returns
+
+### Impact
+
+For a response with 5 `read_file` calls: **~5x faster** execution. The main model still sees all results in order.
+
+---
+
+## Feature 2: SubAgent Delegation
+
+A `SubAgent` tool that lets the main model delegate multi-step tasks to a fast sub-agent. The sub-agent runs autonomously with its own `ConversationRuntime`, making multiple tool calls without round-tripping through the main model.
+
+### Tool parameters
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `prompt` | string | yes | Task description for the sub-agent |
+| `task_type` | string | no | `Explore` (default), `Plan`, or `Verify` |
+| `model` | string | no | Override the sub-agent model |
+
+### Task types
+
+| Type | Available tools | Use for |
+|------|----------------|---------|
+| `Explore` | read_file, glob_search, grep_search, WebFetch, WebSearch, ToolSearch, StructuredOutput | Searching code, reading files, gathering context |
+| `Plan` | Explore + TodoWrite | Planning approaches with structured todo output |
+| `Verify` | Plan + bash | Running tests, checking builds, verifying changes |
+
+### Configuration
+
+Set the sub-agent model in `~/.claw/settings.json`:
+
+```json
+{
+  "model": "openai/glm-5.1-fast",
+  "subagentModel": "openai/qwen3.6-35b-fast"
+}
+```
+
+If `subagentModel` is not set, the sub-agent uses the same model as the main session (or the `model` override parameter on the tool call).
+
+### Example
+
+Main model prompt: "Find all Rust files that import `ConversationRuntime` and list their paths"
+
+Without SubAgent: 5–10 sequential tool calls (grep → read each file → summarize)
+With SubAgent: 1 SubAgent call → sub-agent does all the work autonomously → returns summary
+
+**Result**: ~10x fewer tokens consumed by the main model, faster overall completion.
+
+### Architecture
+
+The sub-agent reuses the same building blocks as the existing `Agent` tool:
+
+- `ProviderRuntimeClient` — API client with fallback chain
+- `SubagentToolExecutor` — filtered tool access with permission enforcement
+- `ConversationRuntime` — full conversation loop with hooks and compaction
+- `agent_permission_policy()` — auto-approve read-only, deny write tools
+
+Key differences from the `Agent` tool:
+- **Synchronous** — blocks until complete, returns result directly
+- **Lighter** — fewer default tools, focused on the task type
+- **Configurable model** — uses `subagentModel` or the tool's `model` param
+- **Structured output** — returns `result`, `tool_calls`, and `iterations`

Author	SHA1	Message	Date
clawdbot	590f5a2e09	fix(clippy): resolve new lint violations in trident, compact, and claw-rag-service - runtime/trident.rs: derive Default, fix for_kv_map, if_same_then_else, extend_with_drain, unnecessary_cast, needless_borrows - runtime/compact.rs: fix useless_borrows_in_formatting - claw-rag-service/ingest.rs: remove unnecessary into_iter() - claw-rag-service/db.rs: use as_chunks instead of chunks_exact, remove unused import All tests pass (1014 Rust + 47 Python tests verified).	2026-10-12 23:01:12 +00:00
TheArchitectit	0403fe8867	fix(cli): order parallel tool results by call index and cap fan-out execute_batch already keyed results to original call slots; this makes that airtight: panicking worker threads resolve to their own index via a fallback tuple instead of colliding with slot 0, and results are asserted to follow call order with a regression test that mixes a workspace-escape read among valid reads at cap=2. Adds the fan-out bound: parallel-safe calls run in waves of at most maxParallelToolCalls (default 8, CLAWD_PARALLEL_TOOL_CALLS env, or the new setting applied via with_max_parallel_tool_calls at runtime build). Sequential behavior is preserved: allowed_tools checks still run before dispatch, and ToolSearch stays off the parallel path.	2026-10-12 23:01:12 +00:00
TheArchitectit	407f0be972	feat(teams): bound per-team sub-agent concurrency with AgentGate TeamCreate resolves maxConcurrentAgents from the per-team input, then the maxConcurrentAgents setting, then unlimited (pre-fix behavior). The cap is persisted in the manifest and registered on a process-wide gate; agent threads still spawn immediately but block on an RAII slot before entering their run loop, so manifest/task-claim semantics are unchanged. TeamDelete forgets the gate so queued agents drain and no stale team entries accumulate. Includes a gate regression test.	2026-10-12 23:01:12 +00:00
TheArchitectit	98c45990db	feat(config): parse maxParallelToolCalls and maxConcurrentAgents settings Adds optional positive-integer parsing for the two new fan-out caps next to subagentModel, in both camelCase and snake_case forms. Zero parses as unset; non-numeric values are a named config error. Covered by three regression tests mirroring the subagentModel test style.	2026-10-12 23:01:12 +00:00
TheArchitectitandClaw	beb5595551	fix: restore workspace unsafe_code=forbid, fix TaskClaim TOCTOU, remove TUI deps Review fixes for PR #3250: 1. Restore workspace-level unsafe_code = "forbid" (was downgraded to "warn" for TUI support). The per-crate [lints.rust] unsafe_code = "allow" on rusty-claude-cli already overrides it where needed. 2. Fix TaskClaim TOCTOU race in claim_task(). Replace exists()-then-write with OpenOptions::create_new(true) which atomically fails if the lock file already exists, eliminating the race window between the check and the write. 3. Remove TUI scaffolding deps (ratatui, tui-textarea, gag, crossbeam-channel, libc, unicode-width) and the /tui slash command spec — these belong in a future TUI PR and are unused in the current source. Also updates the provider chain precedence test to reflect the new behavior where the caller's resolved model is the chain primary.

Provider namespace separation: - New 'custom-openai' provider kind with dedicated env vars (CLAWCUSTOMOPENAI_API_KEY / CLAWCUSTOMOPENAI_BASE_URL) - /setup wizard saves kind: 'custom-openai' for option 5 - Bare model name normalized to 'custom/' prefix to avoid proxy 404s - Sub-agents inherit /setup-saved provider config via inject_config_as_env_fallbacks Parallel tool execution: - Override execute_batch to classify read-only tools as parallel-safe and run them concurrently via std::thread::scope - Results return in original model order Team coordination layer: - AgentMessage, TaskClaim, TeamStatus tools + shared mailbox directory - Mode presets (tiny/1x ... mega/6x) + enriched TeamCreate/Agent descriptions - Background team watcher - /team slash command: on/off/status/toggle Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-10-12 23:00:40 +00:00
