Slack go-live: pre-deploy setup (App creation + Railway env vars)

Context

Pre-deploy operational setup for the outpost-slack-bot service. Code is shipped (@slack/bolt Socket Mode app, message + action handlers, slash commands, health server) — this is configuration.

Timing: Week 2 platform — Discord + GitHub launch first.

Source: the Outpost go-live runbook (internal), Phase 1e.

Checklist

Slack App (api.slack.com/apps)

• Create the Slack App in the workspace
• Bot scopes: chat:write, channels:history, channels:read, users:read, reactions:read, commands
• App-level token scope: connections:write (required for Socket Mode)
• Enable Socket Mode (no public webhook URL required)
• Generate SLACK_BOT_TOKEN (xoxb-...)
• Generate SLACK_APP_TOKEN (xapp-...)
• Note SLACK_SIGNING_SECRET from app settings
• Install / authorize the app to the workspace
• Register slash commands matching the bot's command registry (see apps/slack-bot/src/commands/)

Slack Connect channel onboarding (per-customer)

• Identify the Slack Connect channels where the bot should listen (list tracked internally)
• Customer-side admin invites the bot to each Slack Connect channel
• Collect channel IDs → comma-separated list for MONITORED_CHANNEL_IDS

Railway env vars on outpost-slack-bot

• SLACK_BOT_TOKEN
• SLACK_APP_TOKEN
• SLACK_SIGNING_SECRET
• SLACK_SOCKET_MODE=true
• MONITORED_CHANNEL_IDS — Slack channel IDs (NOTE: same env-var name as Discord uses; Railway scopes per-service, so this is OK)
• TEAM_MEMBER_IDS — comma-separated team Slack user IDs (excluded from AI triggers — see apps/slack-bot/src/config.ts:10)
• Shared via Railway refs: DATABASE_URL, ANTHROPIC_API_KEY, PATHFINDER_MCP_URL

Acceptance

• Slack App exists with the listed scopes + Socket Mode enabled
• Bot invited to at least one Slack Connect channel for the launch
• All env vars populated on the Railway service

Review the command registry in apps/slack-bot/src/commands/ and the team-member configuration at apps/slack-bot/src/config.ts:10 before setting up the Slack app. Configure the listed Slack scopes, Socket Mode, channel access, and Railway variables, then verify the app is installed, invited to a launch channel, and all required variables are populated.
