**CRITICAL: Never use `Read`, `Edit`, or `Write` tools on `~/.cyrus/.env` or any file inside `~/.cyrus/`. Use only `Bash` commands (`grep`, `printf >>`, etc.) to interact with env files — secrets must never be read into the conversation context. Never scrape, extract, or read secret values from web pages — guide the user to copy them manually.**

# Setup Slack

Creates a Slack application from a pre-built manifest so Cyrus can respond to messages in Slack channels.

## Step 1: Check Existing Configuration

```bash
grep -E '^SLACK_BOT_TOKEN=' ~/.cyrus/.env 2>/dev/null
```

If `SLACK_BOT_TOKEN` is already set, inform the user:

> Slack is already configured. Skipping this step.
> To reconfigure, remove `SLACK_BOT_TOKEN` and `SLACK_SIGNING_SECRET` from `~/.cyrus/.env` and re-run.

Skip to completion.

## Step 2: Read Variables

Read the base URL (set by `setup-endpoint`):

```bash
grep '^CYRUS_BASE_URL=' ~/.cyrus/.env | cut -d= -f2-
```

You also need `AGENT_NAME` and `AGENT_DESCRIPTION` — these were collected in Step 0 of the orchestrator and should be available from the conversation context.

## Step 3: Build Manifest JSON

Construct the manifest, substituting `<AGENT_NAME>`, `<AGENT_DESCRIPTION>`, and `<CYRUS_BASE_URL>` with actual values.

**IMPORTANT: Use the manifest template EXACTLY as shown below.** The event subscription path MUST be `/slack-webhook` (not `/slack/events` or any other path). This matches the route registered by `SlackEventTransport` in the Cyrus codebase.

**NOTE: this list of scopes must be kept in sync with the Slack App configuration and the list of scopes defined at [https://github.com/cyrusagents/cyrus-hosted/blob/main/apps/app/src/lib/slack/constants.ts](https://github.com/cyrusagents/cyrus-hosted/blob/main/apps/app/src/lib/slack/constants.ts). If you change scopes here, propose matching changes there and update any live Slack App configuration that relies on this manifest.**
