## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Slack conversations use the same tasks and agents as the Paperclip board. > - A board reply must reach that Slack conversation and let the agent continue the work. > - An assigned agent also needs its Slack tools during normal tasks and scheduled routines. > - Both paths must keep the linked user's authority, delivery rules, and conversation history. > - This pull request adds those paths and reduces setup friction for Slack bots. ## Linked Issues or Issue Description **Subsystem affected** Server orchestration, Slack connector tools, shared contracts, and chat setup UI. **Problem or motivation** Replies entered in Paperclip did not provide a complete round trip to the linked Slack thread. Slack and board wakeups could select different model sessions for the same task. Agents also lacked their assigned Slack tools outside Slack-origin work, which prevented a routine from sending its responsible user a briefing. Inviting a bot could leave the new channel disabled. **Proposed solution** Mirror human board messages with author attribution and route the agent result to the same thread. Use the same session key across both entry points. Supply Slack tools to the connection's assigned agent in normal tasks and routines, using the current responsible user's verified link. Enable newly invited channels while preserving explicit disabled choices. Add a browser-agent setup prompt to the Slack wizard. **Alternatives considered** A separate Slack scheduler or task dispatcher would duplicate existing Paperclip workflows. Reusing the connection owner's identity would grant the wrong authority. Replaying old channel history could start unintended work. This change uses ordinary task wakeups, routine dispatch, and Slack's original invitation mention event instead. **Roadmap alignment** Extends the shipped Scheduled Routines and governed Apps capabilities. It does not add a separate task lifecycle. Related work: #13828 and #13809. Related test stabilization: #13877. The existing plugin Slack-control proposals are separate from this built-in connector change. ## What Changed - Queue human Paperclip messages for the original Slack thread with display-name attribution and stable delivery identities. Require the author’s current linked Slack identity and recheck access before delivering messages or agent replies. - Apply pause, dependency, cancellation, and closed-workspace guards before explicit Board sends request work and again when the durable outbox dispatches it. - Route agent results back to Slack and preserve model-session continuity, including replies that reopen completed tasks. - Resolve assigned Slack connections for normal agent tasks and routines. Recheck the responsible user's link, membership, and permissions at execution. - Add `slack_open_dm` for the responsible user's bot DM and request the `im:write` scope. - Enable newly discovered invited channels. Keep explicit OFF choices and normal admission and deduplication rules. - Add a copyable Slack setup prompt for a computer-use agent, with Storybook coverage. Share the prompt-button component with GitHub. - Update Slack tool documentation and runtime instructions. - Stabilize the mobile project browser test by waiting for the final canonical route before editing, preserving all persistence assertions. ## Verification - Live staging: invited the bot after the first mention. The channel became enabled and the bot answered that original mention. - Live staging: a normal Paperclip reply appeared in Slack with author attribution. The agent completed the calculation and replied once in the original thread and in Paperclip. - Live staging: a codeword entered in Slack was recalled from Paperclip. A following Slack calculation used the result from the Paperclip turn. Run metadata confirmed the same model session for both entry points. - Live staging: a scheduled routine used `slack_open_dm` and `slack_post_message` to deliver one DM. The existing app was reinstalled with `im:write`. The test routine was paused after verification. - Before the master merge: 397 focused feature tests passed. The continuity fix passed all 76 issue comment/update route tests and six focused route/integration cases. Typecheck, build, and token gates passed. - Review fixes: 47 focused integration cases passed, covering link revocation/replacement, private membership removal, guarded outbox dispatch, concurrent workers, lost scheduler responses, a real one-connection pool, exact reply provenance, and attachment retries. All 99 issue-comment route tests and the Slack catalog browser test passed. - Full local typecheck, production build, token gates, and module-boundary checks passed. The full local test command passed 25,915 tests before a 15-second timeout in `issue-thread-interaction-routes.test.ts`; that entire suite passed on isolated rerun (81 tests). Remaining serialized coverage is provided by the current-head CI shards. - An unchanged Cursor adapter test hit its 10-second limit in CI; all five tests in that file passed on a local rerun in 3.11 seconds, and the failed CI shard passed on its single retry. - The preview-server readiness test passed a local rerun (28 tests). The mobile-project readiness fix passed three repetitions of both browser tests (6/6). - Final commit `64ac0d9897f4353375996f1b1b38e5040bdeb0a0`: all CI gates passed, including all eight browser shards, all server/chat suites, typecheck, build, runner checks, and security checks. Greptile reviewed this exact commit at 5/5; all review threads are resolved. ## Risks - Human messages on a Slack-linked task now publish to its Slack thread. The task banner states this behavior. Incoming Slack messages and internal agent bookkeeping must not echo back. - Normal tasks and routines can now use the assigned bot. Authority remains bound to the current responsible user's link; it does not fall back to the connection owner. Revocation, private-context limits, and queued-write checks still apply. - Existing Slack apps need `im:write` and a reinstall to open DMs. Other existing capabilities remain available without that scope. - New invited channels default to enabled. Explicit disabled choices remain disabled. Channels created by bot tools still require a person to enable responses. - No database migration or new provider credentials are required. ## Model Used OpenAI GPT-6 through Codex, with reasoning, code execution, GitHub CLI, and browser tools. The runtime does not expose a more specific model build identifier or context-window size. ## 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 - [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>
