## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Task conversations keep follow-up messages pending while an agent works. > - The screen combines optimistic sends, queue snapshots, and run input records. > - A late send response can restore a local queue flag after a run takes the message. > - A stale queue snapshot can then keep the same message in pending. > - This pull request matches the input record to its source queue and clears stale pending flags. > - The benefit is that consumed messages leave pending while unsent messages stay visible. ## Linked Issues or Issue Description **What happened?** A follow-up can remain in the task composer's pending row after a run takes it as input. Local queue state can outlive the send request. The old projection cleared that state for steering, but not for ordinary run-start input. A stale queue read can also retain the consumed entry. **Expected behavior** A message that a started run takes as input appears once in history and leaves pending. Other pending messages remain available. A message assigned to a run that has not started remains pending. **Steps to reproduce** 1. Send a follow-up while a task has a live run. 2. Let a started run record that message as input before or after the send response arrives. 3. Let a queue read still include the consumed message. 4. Observe the message remain pending on the base revision. **Paperclip version or commit** Reproduced against master at `33d24e48ad` with controlled request ordering. **Deployment mode** Source checkout. Browser verification used the production task screen with a simulated native runner and delayed API responses. It did not run a live model or change a deployed instance. Related: [PR #15030](https://github.com/paperclipai/paperclip/pull/15030) addresses acknowledgement matching in the runner console. This change addresses the task-detail composer and does not modify that console. ## What Changed - Clear local pending flags when a started run records the comment as input. - Use live-run input IDs while the run-history query catches up. - Match stale queue entries by their primary or coalesced source wake ID, even when the snapshot targets the previous run or has no target. - Retain coalesced source queue IDs in run context and include receipt IDs in compact task run reads. - Keep unstarted run inputs and authoritative retries pending. Cover send ordering, same-run and successor delivery, queued snapshots, coalesced inputs, and retry consumption. - Add the delivery-race checks to the steering feature map. ## Verification - Before the fix, the first four request-order regressions failed with the consumed message still in pending. Coverage now includes 16 combinations of receipt source, send-response order, and stale snapshot kind. - Focused UI checks: 5 files and 233 tests passed. These cover task detail, queue projection, optimistic comments, queued-message controls, and the task-chat adapter. - `pnpm -r typecheck` passed. - Server receipt checks: 5 files and 139 tests passed with `PAPERCLIP_TEST_POSTGRES_TEMPLATE=0`. These exercise real database reads, coalesced heartbeat input, and polling routes. The default cached-template path timed out during setup on this host; the fresh-cluster path passed without longer timeouts. - Token gates and `node scripts/check-maps.mjs` passed. - Browser: sent a follow-up with a delayed response in the production task screen. The consumed message moved into history. A second unsent follow-up stayed queued. Reload preserved both states. The API and runner were simulated. - `pnpm build` passed. - The full local repository test run was started, then stopped to isolate database setup timeouts. All 55 GitHub CI checks passed on `4ec6820cf1f89880b801fd5f938d72f54591c5e2`, including the full test matrix. One serialized server shard passed on its single rerun after a 15-second route-test timeout; the same 97-test route suite also passed locally. - Greptile reviewed the final head at 5/5. All review threads are resolved. ## Risks - Queue display depends on matching comment IDs, source queue IDs, and a recorded start time. Rows without start evidence stay pending. Newer queues remain visible until their own input receipt arrives. - Run context gains additive receipt metadata. No schema migration is required. Dispatch order, stored queue state, company access, and steering authority stay unchanged. - Browser evidence covers controlled response ordering. It does not establish deployment or live-provider behavior. ## Model Used - OpenAI Codex, GPT-6, with reasoning, tool use, and code execution. The exact serving model ID and context-window limit are not exposed in this session. ## 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 #` 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 - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>

# Steering and queued messages
|
|
|
|
People can send follow-ups while an agent works, manage saved messages that have
|
|
not been consumed, and choose when to steer or interrupt. Stopping a run and
|
|
pausing a task are separate controls. The UI must preserve the message, explain
|
|
why it is waiting, and only claim delivery after an authoritative acknowledgement.
|
|
|
|
Agent access: [companion](../agent-access-map/steering.md).
|
|
|
|
## Sub-features
|
|
|
|
- `queue`: a busy task saves follow-ups and shows their order and wait reason.
|
|
- `edit-order-discard`: edit full Markdown, reorder, and discard eligible saved
|
|
messages; ownership, revision conflicts, and already-dispatched states matter.
|
|
- `steer`: explicit user action sends a queued message into a compatible active
|
|
run; unavailable capabilities and provider rejection remain visible.
|
|
- `interrupt`: stop the current execution and carry accepted follow-ups into
|
|
the eligible continuation without delivering them twice.
|
|
- `stop-and-pause`: distinguish stop-in-flight, confirmed stop, task/ancestor
|
|
pause, agent pause, and budget hold. Resume must respect the actual gate.
|
|
- `drafts`: switching tasks, reloading, and uncertain submission retain the
|
|
correct task's draft and attachment receipts.
|
|
- `approval-queue`: answered questions and accepted approvals have durable
|
|
delivery distinct from editable ordinary comments.
|
|
|
|
## How to get to it (user POV)
|
|
|
|
### `task-composer`
|
|
|
|
Open an assigned task (`/issues/:issueId`). Start work, then send follow-ups while
|
|
the agent runs. Use the queued-message controls to edit, reorder, discard,
|
|
steer, or interrupt when offered. Use the composer stop/pause control separately.
|
|
Both task presentations need attention when changing their shared behavior.
|
|
|
|
### `agent-chat`
|
|
|
|
Enable Agent Chat and open an agent conversation. Send another message during
|
|
a reply and inspect the shared queue. `/new` starts fresh provider context in
|
|
the same conversation; it is an ordered boundary, not a normal model prompt.
|
|
|
|
### `request-response`
|
|
|
|
Answer an earlier question or accept a confirmation while successor work is
|
|
active on the task. Inspect the resulting queued response and its available
|
|
steer/interrupt control instead of assuming acceptance interrupted execution.
|
|
|
|
### `external-channel`
|
|
|
|
Send a follow-up from a linked external chat conversation while its task is
|
|
running. Use that provider's supported stop/control affordance where available;
|
|
inspect the resulting task and run in Paperclip.
|
|
|
|
## Driving it
|
|
|
|
Preconditions: follow the [baseline](./README.md#before-driving-a-journey).
|
|
Use an agent that stays busy long enough to inspect the queue. Record the adapter,
|
|
native/legacy mode, and advertised steering capability. Test supported and
|
|
unsupported steering without treating an absent capability as a product failure.
|
|
|
|
### `task-composer`
|
|
|
|
Automated: [queued-message UI](../../ui/src/components/task-chat/TaskChatQueuedMessages.test.tsx)
|
|
covers order, failure restoration, unavailable steering, stale revisions, and
|
|
discard acknowledgements. [Queue routes](../../server/src/__tests__/issue-queued-comments-routes.test.ts)
|
|
cover durable ordering, authorization, steering acknowledgements, interrupt
|
|
recovery, and concurrent dispatch. [Composer](../../ui/src/components/task-chat/TaskChatComposer.test.tsx)
|
|
covers drafts and uncertain saves.
|
|
|
|
[Task-detail delivery races](../../ui/src/pages/IssueDetail.test.tsx) cover a
|
|
consumed message whose send response and queue snapshot arrive late. A started
|
|
run's input receipt removes that message from pending, while a separate unsent
|
|
message stays queued. Admission to a run that has not started is not delivery.
|
|
A later retry of the same message remains visible in its new authoritative queue.
|
|
Receipts retain the primary wake and coalesced source queue IDs. They clear a late
|
|
snapshot even when its target names the preceding run or is null.
|
|
|
|
```sh
|
|
pnpm exec vitest run ui/src/components/task-chat/TaskChatQueuedMessages.test.tsx server/src/__tests__/issue-queued-comments-routes.test.ts
|
|
```
|
|
|
|
Automated stop coverage is separate:
|
|
[composer stop](../../tests/e2e/composer-stop.spec.ts) with
|
|
[its configuration](../../tests/e2e/playwright-composer-stop.config.ts) and
|
|
[ACP stop/continuation](../../tests/e2e/acp-stop-continuation.spec.ts). Inspect their
|
|
fixture and opt-in prerequisites; skipped native cases are not native proof.
|
|
|
|
Manual: queue three distinguishable messages. Edit one, reorder them, reload,
|
|
and confirm the saved order. Discard one and confirm it never reaches execution.
|
|
After a queued message enters a started run, confirm it leaves pending even if
|
|
the send response arrives later. Reload and confirm it appears once in history.
|
|
Steer one while busy and verify the agent receives that exact message once.
|
|
Repeat with a rejected steer and a stale second-tab edit; the UI must preserve
|
|
retryable content and explain the conflict. On a fresh run, interrupt with a
|
|
queued follow-up and verify confirmed stop followed by one continuation. Pause
|
|
the task (and separately its ancestor), preserve a draft, then resume the actual
|
|
hold; no hidden send should occur while paused. Check both task presentations
|
|
when available; the named component tests do not prove every host integration.
|
|
|
|
### `agent-chat`
|
|
|
|
Automated: [agent chat sessions](../../tests/e2e/agent-chat-sessions.spec.ts) covers
|
|
persistent conversation/session behavior with deterministic harness fixtures;
|
|
shared composer tests cover the controls. These do not qualify live steering
|
|
for every harness.
|
|
|
|
Manual: queue two follow-ups while the conversation replies. Reload, edit or
|
|
discard one, then let the other run. Verify one reply and unchanged conversation
|
|
identity. Send `/new`, then a new prompt; old history remains visible, and the
|
|
new turn uses fresh provider context. Verify a useful answer rather than only
|
|
the session-divider UI. Repeat the queue operations with a live capable harness
|
|
when the change touches delivery.
|
|
|
|
### `request-response`
|
|
|
|
Automated: [response delivery](../../server/src/__tests__/question-response-delivery.test.ts)
|
|
proves queueing/coalescing and retry-safe receipts. The queue-route suite tests
|
|
separate comment and approval queues, explicit steering, and fresh-session
|
|
restrictions on plan approvals.
|
|
|
|
Manual: answer an old question during a new run, confirm that it is saved and
|
|
queued, and let the active run end. Verify exactly one continuation with the
|
|
answer. Repeat an eligible approval with explicit steer; another approval that
|
|
requires a fresh session must not offer same-turn delivery. Do not edit an
|
|
approval outcome through an ordinary queued-message editor.
|
|
|
|
### `external-channel`
|
|
|
|
Automated: [chat interaction arbitration](../../server/src/services/chat-interaction-arbitration.test.ts)
|
|
covers backend arbitration with simulated requests. It is not a provider UI test.
|
|
|
|
Manual: send two distinguishable messages through one disposable linked
|
|
conversation while busy. Inspect their saved task order, run delivery, and
|
|
external reply. Check a duplicate provider event and unauthorized sender.
|
|
Provider-specific control semantics and real transport timing remain a manual
|
|
gap; do not assume browser queue controls are available in every channel.
|
|
|
|
## Gotchas
|
|
|
|
- Paperclip's queue is server-owned once saved; it is not Omnigent's unsent
|
|
browser draft buffer. A stale edit must not overwrite a consumed message.
|
|
- Steer availability depends on the active runtime's capability, not its brand
|
|
name. A UI row disappearing optimistically does not prove provider receipt.
|
|
- Interrupt, stop, task pause, agent pause, and budget pause have different
|
|
effects. A running indicator disappearing does not prove remote work stopped.
|
|
- An interrupted run may need verified cleanup before a saved follow-up can
|
|
start. Preserve and inspect the wait reason; see [recovery](./recovery.md).
|
|
- A healthy idle Agent Chat is waiting for input, not stranded unfinished work.
|
|
|
|
### Storybook verification
|
|
|
|
#### `drafts`
|
|
|
|
Scope: ui
|
|
Storybook: Task-keyed restored draft and attachment receipts; task switch/reload, failed send and uncertain-save recovery.
|
|
Production: Retain correct task draft across navigation and reload; inspect authoritative saved receipt before claiming delivery; do not clear storage on every harness mount.
|
|

Tests: [TaskChatComposer.test.tsx](../../ui/src/components/task-chat/TaskChatComposer.test.tsx), [issue-queued-comments-routes.test.ts](../../server/src/__tests__/issue-queued-comments-routes.test.ts)
|
|
|
|
#### `approval-queue`
|
|
|
|
Scope: ui
|
|
Storybook: Answered question/accepted approval delivery waiting, eligible steer/interrupt, failed delivery and fresh-session-only approval.
|
|
Production: Keep response delivery durable and distinct from editable comments; coalesce once, enforce fresh-session restrictions and deduplicate concurrent/retried continuation.
