DottaandPaperclip a10702a878 feat(slack): add governed tools for Slack-origin tasks (#13828)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Chat connectors let people start and continue agent tasks from other
services.
> - A Slack conversation needs access to its surrounding discussion and
Slack collaboration tools.
> - The agent must use the linked requester's access and keep private
material within its permitted audience.
> - This pull request adds Slack tools through the existing connector
contribution and approval framework.
> - People can ask an invited bot to read a discussion, create follow-up
tasks, and collaborate in Slack.

## Linked Issues or Issue Description

**Subsystem affected**

Chat connectors, connector runtime, tool gateway, and connection
Settings/Access.

**Problem or motivation**

Slack-origin tasks can receive messages but cannot inspect the rest of a
channel or act through the originating bot. People must paste context or
configure a separate integration.

**Proposed solution**

Supply typed Slack tools and a bundled skill only to the originating
task and assigned agent. Resolve the linked requester on the server.
Check bot and requester access before reads and writes. Use existing
durable actions and approvals. Retrieved messages remain source
material.

**Alternatives considered**

Slack's user-OAuth MCP server does not replace the customer-created chat
bot. An unrestricted Web API proxy would not provide suitable permission
or publication boundaries.

**Roadmap alignment**

This extends the existing MCP Tool Gateway & Apps work with a provider
contribution. It does not add a task dispatcher or a separate Slack task
lifecycle. Related: #11144 covers generic per-user MCP grant execution;
this change binds Slack bot operations to chat-origin tasks.

## What Changed

- Add 39 typed Slack tools, a method/scope matrix, a bundled skill, and
shared native/HTTP execution.
- Bind tools to company, endpoint, task, run, assigned agent, and
admitted linked requester. Check membership and revocation on each call
and before queued writes.
- Add paginated reads, bounded history search, source links, messages,
file uploads, reactions, pins, bookmarks, topics, canvases, lists, and
approved channel operations.
- Restrict private-source publication, including automatic replies and
uploaded deliverables. Keep other people's bot DMs inaccessible.
- Reuse action receipts, idempotency, approvals, and reconciliation.
Suppress an identical explicit-send/final-reply duplicate. Return
governed results through their verified originating conversation.
- Add endpoint-bound personal search OAuth storage and lifecycle. Keep
native real-time search disabled until a runtime meets Slack's
transient-result requirements. Current runtimes use bounded history
search.
- Show capabilities, scope upgrades, and personal search authorization
in Settings/Access and Storybook. Document provider and runtime limits.

## Verification

- Current head `0eb21cba4`: CI checks pass and Greptile is 5/5 with no
unresolved findings. One unchanged rapid-callback timing test passed on
a single CI retry.
- Approval presentation regressions cover board-comment precedence and
exact Slack publication; the expanded database assertion passed in CI.
The local PostgreSQL startup probe later became unavailable, so that
final assertion was verified in CI. Slack setup and failed-run retry
browser tests also passed locally.

- Full workspace typecheck and build passed. Server typecheck/build
passed again after the approval routing fix.
- Broad local suites passed in separate groups: server 12,958 tests, UI
6,555, shared 770, skills catalog 20, and other workspace packages
2,652. CLI and serialized server checks passed after environment/timeout
retries. These are composite results, not one uninterrupted green
full-suite invocation.
- PostgreSQL authority regression covers admitted identity,
cross-company/task/agent rejection, recovery, retained-session
revocation, OAuth refresh/disconnect races, approval execution, exact
publication lineage, retries, uncertain sends, and duplicate
suppression.
- Gateway/response regressions cover separate-origin approval batches
and durable continuation. Focused provider, access, search, native
runtime, route, and AgentMail regressions pass.
- Storybook capability, missing-scope, OAuth configuration,
authorization, and disconnect states were inspected in the browser.
- Live staging: read a channel decision and full thread, create exactly
two assigned backlog tasks, add a reaction, paginate discovery to
exhaustion, and return bounded search matches with source links and
coverage.
- Live staging: create/edit/read a canvas and list, inspect the canvas
in Slack, post/edit one message, and create a channel only after
approval. New channels remain disabled for responses.
- Live staging: read a response-disabled channel from the requester's
DM; writes to that channel were denied. The test setting was restored.
- Final live retest passed: explicit file upload and exact content
read-back; approved deletion of only the disposable bot message;
continuation confirmation returned to the original Slack thread without
repeating the action.
- Optional OAuth, private multi-user boundaries, native RTS, and CLI
provider execution are not fully live-qualified. The staging agent
initially supplied malformed tool arguments; valid arguments succeeded,
and the tool/skill descriptions now emphasize UUID write keys.

## Risks

- Existing Slack apps must add scopes and reinstall for new
capabilities. Provider plans and document permissions can still restrict
operations.
- Instances need an independent `PAPERCLIP_TOOL_ACTION_SIGNING_SECRET`
for governed tool actions. The staging instance was configured with
explicit operator approval; fleet provisioning is a separate gap.
- Native RTS is not exposed on current transcript-retaining runtimes.
Bounded history scans are deliberately reported as incomplete. Inline
file reads support text/canvas content up to 256 KiB; other types return
metadata.
- Private document edits fail closed when the full audience cannot be
verified. Uncertain effects other than posts/uploads require inspection
instead of blind retries.
- Shared approval-delivery code now separates outcomes by source run to
preserve origin boundaries. No database migration is required.
- A separate completion-validator gap remains when the agent cites a
prior run's registered artifact during finalization. It asked for
registration again even though Slack delivery was confirmed. This change
does not add a connector-specific task-completion policy.

## Model Used

OpenAI GPT-6 through Codex, with repository tools, code execution, and
browser testing. The exact deployed model identifier and context-window
size were not exposed in the session.
