DottaandPaperclip a7dd5284b5 feat: add company fast-response acknowledgements (#15748)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Human messages start agent work through task, chat, and
external-channel intake.
> - Agent startup can delay the first visible response.
> - A small direct model call can acknowledge the request while normal
work starts.
> - This response must remain separate from evidence that the agent
answered or completed work.
> - This pull request adds optional company-wide fast responses with
durable receipts, access checks, and cost accounting.
> - Users receive prompt acknowledgement without changing the agent
execution path.

## Linked Issues or Issue Description

**Subsystem affected**

Cross-cutting: database, shared contracts, server orchestration,
connections, and UI.

**Problem or motivation**

Users can wait for an agent to start before they receive a contextual
response. Generic progress messages do not confirm what the user asked.
An acknowledgement must not falsely complete work or satisfy an
unanswered turn.

**Proposed solution**

Add a disabled-by-default experimental fast-response model using an
existing shared API connection. Generate one short acknowledgement for
each accepted human turn. Use the existing agent identity and external
publication outboxes. Retain platform provenance and account for the
inference independently.

**Alternatives considered**

Running the acknowledgement through the agent runtime adds startup
latency. Restricting implementation to OpenRouter leaves other existing
API connections unsupported. This change supports all existing API
connections and uses OpenRouter for live verification.

**Roadmap alignment**

This extends existing agent communication and connection settings.
ROADMAP.md and open pull requests were checked. No duplicate
fast-response implementation was found. The maintainer supplied the
feature plan directly.

## What Changed

- Add Experimental fast responses to instance settings. Keep the feature
off by default. Enforce the flag at intake, dispatch, and publication.
- Move Decision model and Fast response setup to company Settings →
Connections when the experiment is enabled. Place Connections below
Environments. Separate the model sections with clear headings and a
divider. Keep Decision model in General when the experiment is off.
Route Costs setup links to the available settings page.
- Make the acknowledgement prompt a multiline template string. Ask for a
brief, positive response in the user’s language.

- Add settings, connection/model selection, sponsorship, fixed-sample
testing, and Costs history.
- Add a Vercel AI SDK text service for existing native, routed, Bedrock,
and local API connections.
- Add durable per-turn requests, a bounded worker, a three-second
admission deadline, and one inference attempt.
- Integrate task creation, task and agent chat, steering, queued
follow-ups, experimental board chat, shared chat intake, and email.
- Preserve receipt provenance and exclude receipts from completion,
recovery, interaction resolution, and agent wakeups.
- Recheck authorization, source validity, real replies, budgets, and
destination binding before publication. Preserve accounting for
suppressed or uncertain outcomes.
- Add provider contracts, database race tests, channel outbox tests, UI
tests, Stories, and documentation. Keep decision-model execution
unchanged.

## Verification

- Local `pnpm -r typecheck`, `pnpm build`, and UI token gates pass after
rebase. The UI typecheck and build also pass after the final navigation
fixes. All 37 focused navigation tests pass. The first full local `pnpm
test:run` invocation reported seven chat failures. All seven passed in
isolated reruns after fixture updates and host cleanup. This invocation
was stopped after the full final-head CI suite passed.
- Initial local database tests hit macOS shared-memory exhaustion. A
diagnostic confirmed `shmget: No space left on device` with the system
limit of 32 IDs. Three abandoned, unattached PostgreSQL IPC headers were
reclaimed. The isolated rerun passed all 31 fast-response and channel
tests. The two additional Slack regression cases also passed in a
separate rerun. No active database was stopped.
- UI token gates pass. Provider contract tests cover all supported API
connection types. Fast-response tests cover uniqueness, authorization,
budgets, expiry, cancellation, restart, real-reply races, and the
experimental flag.
- The test drive verified that disabling the experiment hides
Connections and redirects its direct URL. Enabling it restores the saved
OpenRouter setup. After restart on the final commit, the OpenRouter
settings sample returned “Sure, I’ll take care of fixing the border
around the settings panel.” in 428 ms. It used 260 input and 31 output
tokens and recorded $0.0000576 in reported cost.
- Earlier live OpenRouter verification produced a receipt in 1.013
seconds for a new task. The real agent then supplied its substantive
answer. A separate settings test took 1.34 seconds, used 246 input and
23 output tokens, and recorded $0.0000361.
- Live Slack verification on final commit
`24016fa525961ebc7a4acffdc5019ce123970549` passed for a fresh initial
task and a follow-up in a disposable bot DM. The initial acknowledgement
appeared 2.405 seconds after the Slack message and 1.413 seconds after
durable acceptance; the follow-up appeared in 2.322 seconds and 1.160
seconds respectively. The recorded generation/settlement durations were
898 ms and 697 ms. The initial call used 291 input / 39 output tokens
and cost $0.00006705; the follow-up used 281 / 47 and cost $0.00007035.
- The Slack acknowledgements retained the assigned agent identity and
`origin: fast_response`, source-turn references, and no fabricated run
ID. A status snapshot after the initial receipt showed the task still
`in_progress` with its real execution run. The agent then read the CSV
fixture and correctly reported two ready items, two blockers, and their
owners. Both replies stayed in the originating DM, and no duplicate
generic working message followed the delivered contextual
acknowledgements. The `new` command started a fresh conversation session
without generating a fast response.
- An earlier eligible Slack turn generated a response but suppressed
publication. Its reported cost was retained, generic progress remained,
and the real agent completed the requested result. This is recorded
separately from the two delivered acknowledgements; the history did not
expose a precise suppression reason.
- Slack verification used real signed provider events, the existing
intake/publication paths, and a user-approved temporary webhook-only
HTTPS tunnel. Subscriptions were limited to direct-message events. The
test bot was paused and the tunnel stopped afterward. Live
channel/group-thread and GitHub journeys remain unverified; their mocked
tests cover intake, destination binding, publication, and continued
underlying work.
- Greptile reviewed final commit
`24016fa525961ebc7a4acffdc5019ce123970549` at 5/5. Both new review
findings are fixed and all threads are resolved. [Final-head CI
run](https://github.com/paperclipai/paperclip/actions/runs/38060015730)
passed. This includes grouped server/chat/workspace tests, serialized
suites, runner checks, browser journeys, typecheck, build, release
registry, policy, and the canary dry run.
- Manual check: enable Experimental fast responses. Open company
Settings → Connections. Select a shared API connection and model. Save
and use Test response. Submit a task message and confirm that its
receipt does not complete the task.

## Risks

- The migration adds receipt and configuration tables plus accounting
references. It uses idempotent statements and follows the current
migration sequence.
- A slow provider, authorization change, or real-agent reply can
suppress an acknowledgement. Existing progress feedback remains
available.
- Unknown provider billing retains a reservation until reconciliation.
External deliveries with uncertain outcomes must not be blindly
repeated.
- Live Slack initial-task and follow-up DM journeys pass. Live Slack
channel/group-thread and GitHub journeys remain unverified. The PR
remains a draft and records these gaps. Final-head repository CI and
automated review pass.

## Model Used

OpenAI Codex, based on GPT-6, with reasoning, repository tools, code
execution, and browser interaction. The runtime does not expose an exact
model snapshot ID or context-window size; these are not asserted.

Fast response implementation and verification

Finish line

Optional company-wide acknowledgements use existing API connections, preserve the normal agent turn, retain server-controlled provenance, and account for provider work exactly once. OpenRouter leads live verification; other providers are verified by HTTP contracts. Existing decision behavior remains unchanged.

Implementation

  • Company settings, shared API connection selection, model catalog/manual IDs, fixed sample test, availability and Costs history.
  • SDK-backed direct generation across native providers and configured Messages, Responses, Chat Completions, Bedrock and local routes.
  • Durable deduplicated accepted-turn requests with a three-second admission deadline, bounded workers, authorization and budget checks, one inference attempt, and restart quarantine.
  • Platform receipts in task and agent chat, board chat and shared external intake/publication, excluded from completion, unanswered-turn recovery and interaction resolution.
  • Small context prompts, source isolation for external destinations, provenance details and labeled agent context.

Evidence collected

Isolated checkout codex/fast-response, app at http://127.0.0.1:3109, cloned database under /private/tmp/paperclip-fast-response-home.

  • Live OpenRouter openai/gpt-oss-120b settings test: UI 0.95 seconds, 212 input / 31 output tokens, reported cost 0.00504 cents.

  • Live task DOT-302: initial acknowledgement admitted in 1.013 seconds, 261 input / 38 output tokens, reported cost 0.006195 cents. Subsequent human turns also received receipts.

  • The dedicated OpenCode/OpenRouter agent subsequently produced a substantive recommendation in the same task. Its real run succeeded. The receipt did not complete the task; final task status remained in progress because the agent did not mark it done.

  • Provider and service tests cover duplicate workers, provenance/no fabricated run, unchanged task status, unanswered-turn protection, reply/cancel/delete/reassign/edit/revoke races, expiry, unknown billing and fixed sample isolation.

  • Full build passed after rebasing onto master, including the final UI refinements. Repository typecheck passed after the rebase; server typecheck also passed after review fixes. The full test run was stopped after setup timeouts and failures in workspace-runtime/execution-workspace suites; it is not green evidence.

  • All 40 provider contracts passed. Slack/GitHub shared intake/outbox contracts and the email reply-only outbox contract passed. Token gates passed after rebase. The regenerated migration 0324 follows master migration 0323 and passes migration safety checks.

  • Final review corrected accepted/queued wording: a run serving the current turn does not count as older work. Email uses the same state check.

  • The post-rebase focused provider/service/UI run passed all 62 tests. Review regressions now cover receipt labeling in native session handoff, model catalogs isolated from host CLI configuration, route transaction boundaries, Costs navigation, and email migration probe rollback.

  • A final OpenRouter sample exposed copied JSON output. The prompt now explicitly requests plain text and structured output is rejected while retaining charges. The corrected live sample returned a contextual acknowledgement in 1.374 seconds, 246 input / 22 output tokens, reported cost 0.0035600 cents.

  • Rebased onto the email commit/deadline scheduler: receipt publication signals its existing worker in the same transaction. Three email scheduling/receipt checks passed.

  • Review follow-ups share queued-state detection across Slack/GitHub/task/email and defer GitHub generic working comments while a contextual receipt can arrive. Eight focused channel checks passed, plus a substantive GitHub reply after receipt; server typecheck passed. Failed generation preserves generic feedback and uncertain external delivery does not trigger a duplicate acknowledgement.

  • Review found quarantined history could lose its label in the prompt. Current and recent comments now use the established quarantine sanitizer; all 22 fast-response service tests passed, including both new source-trust cases, and server typecheck passed.

Verification still required

  • Live Slack bot creation and conversation; browser login completed. A narrow callback relay is prepared. Cloudflare tunneling was rejected by automatic approval review; explicit user authorization is pending.
  • Live GitHub test journey in paperclipai/paperclip-permissions-smoke-20260926-pap57-fee7428e.
  • Latest-head CI and automated review. CI identified additional startup/route fixtures and exact guidance/wiring expectations that need to include fast responses; the corrected focused runs passed (12 closed-workspace routes, 5 native answer continuations, 36 startup tests, and 14 publication/reconciliation tests). Native continuation verification explicitly disables the ambient worktree suppression flag only in the test process. Copied historical run recovery failed during live testing; execution in the cloned workspace is now disarmed, and the app health endpoint reports startup ready.

No credentials or prompt bodies belong in this record.
