## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The task chat shows what an agent does in a run. The Paperclip Runner sends this activity as canonical provider events. > - Claude runs subagents through its Agent (Task) tool. A run that delegates showed a confusing burst of unrelated tool calls. > - The subagent data was already sent, but it was lost: ACPX dropped `_meta`, the hardened sidecar dropped `rawInput`, and async subagents report "launched" as the tool result. > - This pull request maps each Agent call to a canonical `delegation` event, links each child tool to its subagent, and shows subagents as a collapsible card or tree. > - The benefit is that operators can see what each subagent was asked, what it is doing now, which tools it used, and what it returned. ## Linked Issues or Issue Description Refs #19252 (the docked plan card used the same canonical-event pattern) Refs #19259 (ACPX `_meta` passthrough, merged). This PR builds on it. **What happened?** When a Claude agent used its Agent tool, the task chat showed one generic "Task" row and then the subagents' tool calls as flat rows in the parent turn. The subagent type, prompt, progress and result were not visible. **Expected behavior** Each subagent shows as its own card with its type, description, prompt, live progress summary, nested tool rows and result. Subagents that start together show as one tree with status dots. **Steps to reproduce** 1. Assign a Claude (Paperclip Runner, ACPX) agent a task that asks it to launch three Explore subagents in parallel. 2. Open the task while the run is live. 3. Before this change, the subagents' tool calls appear flat in the parent turn. ## What Changed - **claude-agent-acp patch:** Under the isolated runner context, the patch turns on the SDK option `agentProgressSummaries`. It forwards each subagent's `task_progress` summary and its terminal state and summary onto the spawning tool call as `_meta.claudeCode.subagentProgress` and `subagentState`. Native subagent sessions stay off, because ACPX cannot follow child ACP sessions. - **Runner:** The new file `claude-subagent-lineage.ts` tracks each Agent/Task call across ACP update deltas. It maps the call to `delegation.started|updated|completed` events and stamps child tools with `parentItemId`. An async subagent stays running after its "Async agent launched" result until its own state settles. - **Sidecar path:** `acpx-runtime-sidecar.ts` reads the lineage before it drops `_meta` and `rawInput`. Delegations go out as schema-checked rich events. Child tools carry `parentToolCallId`, which Rust (`acpx_event_payload.rs`, `provider_events.rs`) maps to `parentItemId`. - **Contracts:** The provider-event schema adds optional `prompt` and `result` to delegation children and optional `parentItemId` to tool executions. The protocol modules are regenerated. ACPX Claude now advertises the `delegation` event family. - **UI:** `native-run-events.ts` keeps delegation payloads and the tool parent link. `buildTurnTimelineRows` groups adjacent delegations into a new `subagent_group` row, nests child tool rows (plain and provider-activity shapes), and hides the spawning call's own tool row. The new `TaskChatSubagentCard.tsx` renders the card and tree. A new size token caps the result height. - **Storybook:** The new story `Tasks and conversations/…/Task chat/Subagents` has 7 states. ## Verification - `pnpm --filter @paperclipai/paperclip-runner exec vitest run src/cli src/drivers/acpx src/provider-events.test.ts src/claude-subagent-lineage.test.ts src/protocol` (2069 passed) - `cargo test --release --locked -p paperclip-runner-core --lib` in `packages/paperclip-runner/runner` (488 passed, including the new parent-link test) - `node --test test/protocol-contract.test.mjs test/acpx-sidecar-contract.test.mjs test/acpx-codex-package-contract.test.mjs test/acpx-rich-extensions-package-contract.test.mjs` (48 passed) - `pnpm --filter @paperclipai/ui exec vitest run src/components/task-chat src/components/transcript`, including the new `subagent-timeline.test.ts` - `check:protocol-types`, `check:protocol-manifest`, `check:acpx-profiles` and `pnpm check:token-gates` pass. - **Live test:** A local test-drive instance ran a Claude Opus 5.5 agent on the Paperclip Runner (hardened sidecar path). The agent ran real tasks that launched three parallel Explore subagents. The live view showed "Running 3 subagents · 2 done" with a progress summary. The settled view showed "Ran 3 subagents", each with its prompt, nested tools and its own result text. ## Risks - `agentProgressSummaries` makes Claude Code generate a short progress summary for each running subagent about every 30 seconds. This adds a small model cost to runs that delegate. - The adapter patch reads `task_notification` and terminal `task_updated` messages. A future claude-agent-acp version can change these. The patch hunks then fail to apply, and the dependency bump must update them. - If a delegation event is lost, child tools stay at the top level as before. Nothing is hidden without a matching delegation. - Codex is not changed. Codex subagents need `multi_agent`, which Paperclip keeps off on purpose. Changing that is a separate policy decision. ## Model Used - Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code, with tool use (shell, file edits, browser automation). It did the investigation, implementation, tests and live test. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
