# Slack Integration

## Connection

- **Base URL**: `https://slack.com/api/`
- **Auth**: `Authorization: Bearer $SLACK_BOT_TOKEN` (or `$SLACK_BOT_TOKEN_2` for secondary workspace)
- **Credentials**: `SLACK_BOT_TOKEN` (primary), `SLACK_BOT_TOKEN_2` (secondary workspace)
- **Caching**: 2-minute in-memory cache, max 200 entries; separate user/bot caches

## Server Lib

- **File**: `server/lib/slack.ts`

### Exported Functions

| Function                                                   | Description                                  |
| ---------------------------------------------------------- | -------------------------------------------- |
| `getTeamInfo(workspace)`                                   | Get workspace info                           |
| `listChannels(workspace)`                                  | List channels (paginated, first page cached) |
| `getChannelHistory(workspace, channelId, limit?, cursor?)` | Channel message history                      |
| `searchMessages(workspace, query, count?)`                 | Search messages                              |
| `getUserInfo(workspace, userId)`                           | Get user info (cached per user)              |
| `getBotInfo(workspace, botId)`                             | Get bot info (cached)                        |
| `resolveUsers(workspace, userIds, messages?)`              | Batch resolve user names                     |

## Agent Action

Use `slack-messages` for agent-facing Slack reads. Do not call
`/api/slack/*` directly from the agent.

| Mode            | Args                                                 | Description            |
| --------------- | ---------------------------------------------------- | ---------------------- |
| `team`          | `workspace`                                          | Get workspace info     |
| `channels`      | `workspace`                                          | List channels          |
| `history`       | `workspace`, `channel`, `limit`, `cursor`            | Read channel history   |
| `multi-history` | `workspace`, `channels`, `names`, `limit`, `cursors` | Read multiple channels |
| `search`        | `workspace`, `query`                                 | Search messages        |

## Key Patterns & Gotchas

- Two workspaces supported via workspace parameter ("primary" / "secondary")
- `getChannelHistory` auto-joins channels on "not_in_channel" error, then retries — requires `channels:join` scope
- If auto-join fails, throws a detailed message explaining how to invite the bot
- `searchMessages` may require user token; bot token tried first
- `listChannels` paginates via cursor; only first page is cached
- `getUserInfo` resolves bots via `getBotInfo` when needed
