User presses Enter to confirm and launch the setup wizard. Returns ReadOutcome::ProviderSwap so the REPL loop can hot-swap the model and reprint the connection line.

charset=UTF-8 Content-Transfer-Encoding: 8bit Split the three large LSP files into module directories with sub-files: lsp_transport/ (was 560 lines): - mod.rs (425) — types + LspTransport impl - tests.rs (134) — test module lsp_process/ (was 929 lines): - mod.rs (436) — LspProcess struct + public methods + error types - parse.rs (311) — helper functions and LSP response parsers - tests.rs (194) — test module lsp_client/ (was 1338 lines): - mod.rs (466) — LspRegistry struct + impl, re-exports from types - types.rs (103) — LspAction, LspDiagnostic, LspServerStatus, etc. - dispatch.rs (224) — LspRegistry::dispatch() method - tests.rs (273) — core registry tests - tests_lifecycle.rs (294) — lifecycle and integration tests All files under 500 lines. All 501 runtime tests pass. Clippy clean.

Servers are auto-discovered at REPL startup and lazily started on first use.

If a file was read and then later written/edited, the earlier read is obsolete and removed. Earlier writes superseded by later writes are also dropped. Stage 2 - COLLAPSE: Buffer short chatty exchanges (under 200 chars, no tool calls) and collapse them into dense summary blocks when the threshold is exceeded. Stage 3 - CLUSTER: Group semantically similar messages (same tool names, same file paths, similar lengths) using Jaccard-based fingerprinting and collapse clusters into summary blocks. All three stages run before the existing summary-based compaction, so less data needs to be summarized. Wired into both /compact and the auto-compact retry on context window errors. --- rust/crates/runtime/src/lib.rs | 1 + rust/crates/runtime/src/trident.rs | 791 +++++++++++++++++++++++ rust/crates/rusty-claude-cli/src/main.rs | 9 +- 3 files changed, 798 insertions(+), 3 deletions(-) create mode 100644 rust/crates/runtime/src/trident.rs diff --git a/rust/crates/runtime/src/lib.rs b/rust/crates/runtime/src/lib.rs index b636458812..c8c292ac89 100644 --- a/rust/crates/runtime/src/lib.rs +++ b/rust/crates/runtime/src/lib.rs @@ -9,6 +9,7 @@ pub mod bash_validation;

Architecture: - Add ToolCall/ToolResult types to ToolExecutor trait - Add execute_batch() with default sequential fallback - CliToolExecutor overrides execute_batch to classify tools as parallel-safe or sequential, then runs parallel-safe tools concurrently via thread scopes - run_turn refactored into 3 phases: 1. Pre-hooks + permission checks (sequential, hooks may mutate state) 2. Tool execution (batch, parallel for read-only tools) 3. Post-hooks + session updates (sequential, preserves ordering) Safety guarantees: - Pre/post hooks always run sequentially - Permission checks complete before any tool executes - Tool results pushed to session in original model order - Fallback to sequential for single-tool batches --- rust/crates/runtime/src/conversation.rs | 187 +++++++++++++++++------ rust/crates/runtime/src/lib.rs | 4 +- rust/crates/rusty-claude-cli/src/main.rs | 139 +++++++++++++++++ 3 files changed, 281 insertions(+), 49 deletions(-) diff --git a/rust/crates/runtime/src/conversation.rs b/rust/crates/runtime/src/conversation.rs index 610ba1a879..cea0dabdd5 100644 --- a/rust/crates/runtime/src/conversation.rs +++ b/rust/crates/runtime/src/conversation.rs @@ -57,6 +57,40 @@ pub trait ApiClient { /// Trait implemented by tool dispatchers that execute model-requested tools. pub trait ToolExecutor { fn execute(&mut self, tool_name: &str, input: &str) -> Result;

charset=UTF-8 Content-Transfer-Encoding: 8bit Add a SubAgent tool that lets the main model delegate multi-step read and search tasks to a fast, inexpensive sub-agent. The sub-agent runs autonomously with its own ConversationRuntime, making multiple tool calls without round-tripping through the main model. - SubAgent tool with prompt, task_type (Explore/Plan/Verify), and optional model override - Explore: read_file, glob_search, grep_search, WebFetch, WebSearch - Plan: Explore + TodoWrite - Verify: Plan + bash - subagentModel config field in settings.json (falls back to main model) - Uses ProviderRuntimeClient + SubagentToolExecutor (same as Agent tool) This dramatically reduces token usage for information-gathering tasks. Example: "find all Rust files that import X and summarize their usage" → one SubAgent call instead of 10 sequential main-model round trips. --- rust/crates/runtime/src/config.rs | 20 ++++ rust/crates/runtime/src/config_validate.rs | 4 + rust/crates/tools/MULTI_TOOL_README.md | 118 +++++++++++++++++++ rust/crates/tools/src/lib.rs | 127 +++++++++++++++++++++ 4 files changed, 269 insertions(+) create mode 100644 rust/crates/tools/MULTI_TOOL_README.md diff --git a/rust/crates/runtime/src/config.rs b/rust/crates/runtime/src/config.rs index 1566189282..1bb28caebd 100644 --- a/rust/crates/runtime/src/config.rs +++ b/rust/crates/runtime/src/config.rs @@ -65,6 +65,7 @@ pub struct RuntimeFeatureConfig { sandbox: SandboxConfig, provider_fallbacks: ProviderFallbackConfig, trusted_roots: Vec, + subagent_model: Option, } /// Ordered chain of fallback model identifiers used when the primary @@ -315,6 +316,7 @@ impl ConfigLoader { sandbox: parse_optional_sandbox_config(&merged_value)?, provider_fallbacks: parse_optional_provider_fallbacks(&merged_value)?, trusted_roots: parse_optional_trusted_roots(&merged_value)?, + subagent_model: parse_optional_subagent_model(&merged_value), }; Ok(RuntimeConfig { @@ -414,6 +416,11 @@ impl RuntimeConfig { pub fn trusted_roots(&self) -> &[String] { &self.feature_config.trusted_roots } + + #[must_use] + pub fn subagent_model(&self) -> Option<&str> { + self.feature_config.subagent_model.as_deref() + } } impl RuntimeFeatureConfig { @@ -740,6 +747,19 @@ fn parse_optional_model(root: &JsonValue) -> Option { .map(ToOwned::to_owned) } +fn parse_optional_subagent_model(value: &JsonValue) -> Option { + value + .as_object() + .and_then(|object| { + object + .get("subagentModel") + .or_else(|| object.get("subagent_model")) + }) + .and_then(|v| v.as_str()) + .filter(|s| !s.trim().is_empty()) + .map(|s| s.trim().to_string()) +} + fn parse_optional_aliases(root: &JsonValue) -> Result, ConfigError> { let Some(object) = root.as_object() else { return Ok(BTreeMap::new()); diff --git a/rust/crates/runtime/src/config_validate.rs b/rust/crates/runtime/src/config_validate.rs index 7a9c1c4adc..3f9067fa44 100644 --- a/rust/crates/runtime/src/config_validate.rs +++ b/rust/crates/runtime/src/config_validate.rs @@ -197,6 +197,10 @@ const TOP_LEVEL_FIELDS: &[FieldSpec] = &[ name: "trustedRoots", expected: FieldType::StringArray, }, + FieldSpec { + name: "subagentModel", + expected: FieldType::String, + }, ]; const HOOKS_FIELDS: &[FieldSpec] = &[ diff --git a/rust/crates/tools/MULTI_TOOL_README.md b/rust/crates/tools/MULTI_TOOL_README.md new file mode 100644 index 0000000000..9ae88b82f5 --- /dev/null +++ b/rust/crates/tools/MULTI_TOOL_README.md @@ -0,0 +1,118 @@ +# 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.
