Automatically export a Slack conversation to a JSON file on slack.com. Downloads the full accessible history of one Slack conversation as a JSON file, including thread replies.

## Run it

Ask an AI agent connected to Reduck over MCP (`https://mcp.reduck.ai/mcp`) to run `reduck/slack.com/export_conversation`, or run it from a terminal:

```bash
npx @reduck-ai/cli@latest run --script reduck/slack.com/export_conversation
```

## Input

- `conversation` (string, required): What to export. A channel as '#general' or 'general'; any conversation by its ID (C, G or D prefix); a direct message as '@handle' or the other person's user ID; or 'self' for your own saved messages. Display names are rejected because several people can share one, so use a handle or an ID.
- `expectedUser` (string, required): Your Slack handle, display name, or user ID. Checked against the signed-in account before anything is exported.
- `workspaceDomain` (string, required): Workspace hostname, for example acme.slack.com.
- `maxPages` (integer, optional): Safety cap across history and reply pages. Exceeding it fails rather than downloading a partial archive.
- `inspectOnly` (boolean, optional): Resolve and report the workspace, account and conversation without reading history or downloading anything.

## Output

- `account` (object, required)
- `workspace` (string, required)
- `conversationId` (string, required)
- `inspectionOnly` (boolean, required)
- `conversationType` (string, required)
- `download` (object, optional)
- `pageCount` (integer, optional)
- `threadCount` (integer, optional)
- `counterparty` (object | null, optional)
- `messageCount` (integer, optional)
- `lastTimestamp` (string | null, optional)
- `firstTimestamp` (string | null, optional)
- `conversationName` (string | null, optional)
- `completeForAccessibleHistory` (boolean, optional)
