Summary

  • GA slack_v2: drop the preview flag, register SlackV2BlockMeta, hide the legacy slack block from discovery (existing workflows keep executing — triggers.enabled stays on because webhook-execution gates on it at runtime)
  • custom-bot wizard manifests migrate to the agent messaging experience: features.agent_view (new Slack apps can no longer use assistant_view), agent event set (app_home_opened, app_context_changed, message.im), description capped at Slack's 300-char limit
  • new app_context_changed trigger event with context (entities) passthrough in the webhook normalizer
  • no copilot entitlement — slack_v2 is public, so the evaluator is gone; deploy before mothership PR simstudioai/mothership#365

Type of Change

  • New feature

Testing

capabilities + slack provider vitest passing (incl. agent_view/event-set/cap tests), tsc clean, API validation audit passed; exercised live against a real Slack workspace (wizard app creation, mention/DM bots, buttons + modal submits)

PR Summary

Medium Risk
Changes Slack app manifests and discovery for a widely used integration; misconfiguration could affect new bot setups, while v1 execution paths are explicitly preserved.

Overview
Slack v2 is generally available — the preview gate is removed, SlackV2BlockMeta is registered, and the legacy slack block is hidden from discovery with a sunset pointer to slack_v2. Existing v1 workflows keep running; v1 webhook triggers stay enabled because runtime execution depends on that flag.

Custom-bot manifests move to Slack’s current agent messaging model: features.agent_view (replacing deprecated assistant_view), agent-oriented copy in the wizard, agent_description capped at 300 characters, and bot events app_home_opened, app_context_changed, and message.im instead of assistant_thread_*.

Triggers and webhooks add app_context_changed to the event catalog and normalizer, exposing context (viewing entities) on trigger output. Capability tests are updated for the new manifest shape.

Greptile Summary

This PR adds Slack v2 entitlement handling and migrates custom Slack apps to the agent messaging experience. The main changes are:

  • Adds a per-viewer slack-v2 copilot entitlement.
  • Generates agent_view manifests with the new agent event set.
  • Normalizes app_context_changed context into trigger output.
  • Updates Slack setup copy and manifest tests.

Confidence Score: 5/5

This looks safe to merge after a small trigger-output description cleanup.

  • The entitlement remains fail-closed and isolated by workspace and user.
  • Agent manifest generation and webhook routing are consistent with the new event set.
  • The only identified issue is misleading metadata for the new context output.
