From 3253ac95eaa4845545ed20346d9b800e6351189a Mon Sep 17 00:00:00 2001 From: Alex Kesling Date: Wed, 25 Feb 2026 17:28:09 -0500 Subject: [PATCH] feat: cross-entry tool result assembly in toolpath-claude MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tool results in Claude's JSONL are written as separate user entries from the tool invocations that produced them. Previously, ToolInvocation.result was always None and tool-result-only entries became phantom empty turns. Now conversation_to_view() pairs results to invocations by tool_use_id, absorbing tool-result-only entries. The watcher emits turns eagerly and follows up with WatcherEvent::TurnUpdated when results arrive — no buffering, no latency, no stuck state. toolpath-convo 0.2.0: add WatcherEvent::TurnUpdated variant toolpath-claude 0.3.0: assembly in batch + watcher paths, Message::tool_results(), ToolResultRef --- CHANGELOG.md | 14 + Cargo.lock | 4 +- Cargo.toml | 4 +- crates/toolpath-claude/Cargo.toml | 2 +- crates/toolpath-claude/README.md | 27 +- crates/toolpath-claude/src/lib.rs | 3 +- crates/toolpath-claude/src/provider.rs | 489 +++++++++++++++++++++++-- crates/toolpath-claude/src/types.rs | 78 ++++ crates/toolpath-convo/Cargo.toml | 2 +- crates/toolpath-convo/README.md | 2 +- crates/toolpath-convo/src/lib.rs | 12 +- site/_data/crates.json | 4 +- 12 files changed, 607 insertions(+), 34 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index fd038b3..1df4226 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -2,6 +2,20 @@ All notable changes to the Toolpath workspace are documented here. +## 0.2.0 — toolpath-convo / 0.3.0 — toolpath-claude + +### toolpath-convo 0.2.0 + +- Added `WatcherEvent::TurnUpdated` variant for signaling when a previously-emitted turn has been updated with additional data (e.g. tool results that arrived in a later log entry) + +### toolpath-claude 0.3.0 + +- **Breaking (behavioral):** `conversation_to_view()` and `ConversationProvider::load_conversation()` now perform cross-entry tool result assembly — tool-result-only user entries are absorbed into the preceding assistant turn's `ToolInvocation.result` fields instead of being emitted as separate phantom empty turns +- **Breaking (behavioral):** `ConversationWatcher` trait impl now emits `WatcherEvent::TurnUpdated` when tool results arrive, instead of emitting phantom empty user turns +- Added `Message::tool_results()` convenience method and `ToolResultRef` type, symmetric with `tool_uses()`/`ToolUseRef` +- Added shared `merge_tool_results()` that pairs results to invocations by `tool_use_id` +- Thanks to the crabcity maintainers for the detailed design request + ## 0.2.1 — toolpath-claude ### toolpath-claude 0.2.1 diff --git a/Cargo.lock b/Cargo.lock index 1dcfd37..77e0f7f 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1092,7 +1092,7 @@ dependencies = [ [[package]] name = "toolpath-claude" -version = "0.2.1" +version = "0.3.0" dependencies = [ "anyhow", "chrono", @@ -1127,7 +1127,7 @@ dependencies = [ [[package]] name = "toolpath-convo" -version = "0.1.0" +version = "0.2.0" dependencies = [ "chrono", "serde", diff --git a/Cargo.toml b/Cargo.toml index 8eee055..cca8f2d 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -15,9 +15,9 @@ license = "Apache-2.0" [workspace.dependencies] toolpath = { version = "0.1.5", path = "crates/toolpath" } -toolpath-convo = { version = "0.1.0", path = "crates/toolpath-convo" } +toolpath-convo = { version = "0.2.0", path = "crates/toolpath-convo" } toolpath-git = { version = "0.1.3", path = "crates/toolpath-git" } -toolpath-claude = { version = "0.2.1", path = "crates/toolpath-claude", default-features = false } +toolpath-claude = { version = "0.3.0", path = "crates/toolpath-claude", default-features = false } toolpath-dot = { version = "0.1.2", path = "crates/toolpath-dot" } serde = { version = "1.0", features = ["derive"] } diff --git a/crates/toolpath-claude/Cargo.toml b/crates/toolpath-claude/Cargo.toml index 25d029d..0f330bd 100644 --- a/crates/toolpath-claude/Cargo.toml +++ b/crates/toolpath-claude/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "toolpath-claude" -version = "0.2.1" +version = "0.3.0" edition.workspace = true license.workspace = true repository = "https://github.com/empathic/toolpath" diff --git a/crates/toolpath-claude/README.md b/crates/toolpath-claude/README.md index 0046113..52b61ac 100644 --- a/crates/toolpath-claude/README.md +++ b/crates/toolpath-claude/README.md @@ -105,7 +105,12 @@ while let Some(entries) = handle.recv().await { ## Provider-agnostic usage This crate implements `toolpath_convo::ConversationProvider`, so consumers can -code against the provider-agnostic types instead of Claude-specific structures: +code against the provider-agnostic types instead of Claude-specific structures. + +Tool results are automatically assembled across entry boundaries — Claude's JSONL +writes tool invocations and their results as separate entries, but +`load_conversation` pairs them by `tool_use_id` so `ToolInvocation.result` is +populated and tool-result-only user entries are absorbed (no phantom empty turns): ```rust,ignore use toolpath_claude::ClaudeConvo;
