Summary: Replace Composio Slack with agent-slack CLI

Net effect: -819 lines removed, +472 lines added across 11 files. Composio as the Slack
middleware is fully replaced with agent-slack CLI invocations, and the settings UI now
features a workspace picker.

Backend / Core Changes

1. packages/core/src/application/assistant/skills/slack/skill.ts — Rewritten

• Removed: Composio tool catalog import, all slack-* tool references (slack-checkConnection,
  slack-sendMessage, etc.), Composio workflow/discovery instructions
• Added: Full agent-slack CLI documentation — auth checking (agent-slack auth test), messages
  (list/send/edit/delete), search, channels, users, canvases, multi-workspace --workspace flag,
  token budget control (--limit, --max-body-chars)
• The agent now uses executeCommand to run CLI commands instead of custom Composio tools
• Best practices preserved (show drafts, summarize don't dump) plus new ones: resolve user IDs
  by batching agent-slack user get calls with ; separators

2. packages/core/src/application/assistant/skills/slack/tool-catalog.ts — Deleted

• Removed the entire 117-line Composio tool slug catalog (113 Slack tool definitions like
  SLACK_SEND_MESSAGE, SLACK_FETCH_CONVERSATION_HISTORY, etc.)

3. packages/core/src/application/lib/builtin-tools.ts — 387 lines removed

• Removed all Composio/Slack imports (composioAccountsRepo, executeComposioAction,
  isComposioConfigured, listToolkitTools, slackToolCatalog)
• Removed SlackToolHint type, slackToolHints config, slackToolSlugCache,
  slackToolSlugOverrides, compactObject, SlackToolResult
• Removed helper functions: executeSlackTool, normalizeSlackTool, scoreSlackTool,
  pickSlackTool, resolveSlackToolSlug
• Removed all 10 slack-* tool definitions (slack-checkConnection, slack-listAvailableTools,
  slack-executeAction, slack-sendMessage, slack-listChannels, slack-getChannelHistory,
  slack-listUsers, slack-getUserInfo, slack-searchMessages, slack-getDirectMessages)

4. packages/core/src/slack/types.ts — New file

• Defines SlackWorkspace schema ({ url, name }) and SlackConfig schema ({ enabled,
  workspaces[] })

5. packages/core/src/slack/repo.ts — New file

• FSSlackConfigRepo — reads/writes ~/.rowboat/config/slack.json, follows the same pattern as
  FSGranolaConfigRepo

6. packages/core/src/di/container.ts — 2 lines added

• Imports and registers FSSlackConfigRepo as slackConfigRepo singleton

7. packages/core/src/application/assistant/instructions.ts — 1 line changed

• Minor adjustment (likely import path cleanup)

IPC / Main Process Changes

8. packages/shared/src/ipc.ts — 23 lines added

• Added 3 new IPC channels:
  • slack:getConfig — returns { enabled, workspaces[] }
  • slack:setConfig — accepts { enabled, workspaces[] }
  • slack:listWorkspaces — returns { workspaces[], error? }

9. apps/main/src/ipc.ts — 29 lines added

• Added exec and promisify imports from node:child_process / node:util
• slack:getConfig handler — reads from slackConfigRepo
• slack:setConfig handler — writes to slackConfigRepo
• slack:listWorkspaces handler — runs agent-slack auth whoami via execAsync, parses JSON
  output, maps workspace_url/workspace_name to { url, name }. Returns { workspaces: [], error }
  on failure.

UI Changes

10. apps/renderer/src/components/connectors-popover.tsx — Major rewrite (~255 lines changed)

• Removed: ComposioApiKeyModal import/usage, all Composio state (composioApiKeyOpen,
  slackConnecting), Composio IPC calls (composio:get-connection-status,
  composio:initiate-connection, composio:disconnect, composio:is-configured,
  composio:set-api-key), composio:didConnect event listener
• Added: Workspace picker state (slackWorkspaces, slackAvailableWorkspaces, slackSelectedUrls,
  slackPickerOpen, slackDiscovering, slackDiscoverError)
• New flow:
  • Disabled state → "Enable" button
  • On click → calls slack:listWorkspaces → shows inline checkbox list of discovered
    workspaces → "Save" button
  • Error case → shows helpful message about running agent-slack auth import-desktop
  • Enabled state → Switch toggle (on) to disable, workspace names shown as subtitle
  • Disable → clears workspaces and sets enabled: false

11. apps/renderer/src/components/onboarding-modal.tsx — Major rewrite (~265 lines changed)

• Same Composio→agent-slack migration as connectors-popover
• Removed: ComposioApiKeyModal, Composio state/handlers/event listeners
• Added: Same workspace picker pattern (Enable button → discover → checkboxes → Save)
• Slack row re-enabled in the "Connect Accounts" onboarding step (was previously commented
  out)
• Completion step shows selected workspace names when Slack is enabled
