Connect Your AI Agent to Slack, Email, and Discord with ClawHub Skills
A practical guide to ClawHub's communication skills for Claude Code — Slack, Gmail, Discord, and Telegram integrations that let your AI agent send messages, read channels, and act on notifications.
Connect Your AI Agent to Slack, Email, and Discord with ClawHub Skills
There's a specific kind of frustration that comes from having a capable AI agent that's isolated from everything else. You finish a long automated task, but you don't know it's done until you check. You want the agent to notify the team when a deployment completes, but it has no way to reach Slack. You'd love to have it summarize your email backlog each morning, but it can't touch Gmail.
ClawHub's communication skills solve exactly this. They give Claude Code real channels to the outside world — Slack, Gmail, Discord, and Telegram — with enough intelligence to use them appropriately rather than just blindly sending messages.
Here's what each one does and when to reach for it.
Slack
The most-used communication skill on ClawHub. The Slack skill gives Claude Code read and write access to your Slack workspace, scoped to the channels you authorize during setup.
What you can do with it:
- Post notifications when automated tasks complete
- Read channel history to summarize what you missed
- Search for decisions or context buried in old threads
- Send direct messages to teammates
- Create formatted messages with code blocks and attachments
Install:
/skills install slack
Setup: The skill walks you through OAuth with your Slack workspace. You select which channels to grant access to — you don't need to authorize everything, and you shouldn't.
Usage examples:
You: Post to #deployments when the build finishes
Agent: I'll post a summary to #deployments once the build completes.
[30 minutes later]
Posted: "Build #482 complete. 3 tests passed, 0 failed.
Deployed to staging. Duration: 4m 32s"
You: What did I miss in #eng-team today?
Agent: 6 messages since 9am. Key items:
— Sarah flagged a memory leak in the auth service (thread at 10:23am)
— Sprint planning moved to Thursday
— New API keys rotated, check your .env
Limitation worth knowing: The skill doesn't handle real-time message monitoring by default. It reads channel history on demand rather than listening for incoming messages continuously. If you need reactive behavior (agent responds when mentioned), that requires additional configuration with webhooks.
Gmail
Email is still where critical information lives for most developers — vendor notifications, security alerts, API credentials, client communications. The Gmail skill gives Claude Code controlled read/write access to your inbox.
What you can do with it:
- Summarize unread emails by sender or label
- Draft and send replies with your voice and tone
- Search for specific emails (order confirmations, API keys, invoices)
- Archive or label emails based on rules
- Extract action items from email threads
Install:
/skills install gmail
Setup: Requires Google OAuth. You authorize specific scopes — read-only is available if you don't want the agent to send emails on your behalf.
Usage examples:
You: Summarize what needs my attention in my inbox
Agent: 12 unread emails. Actionable items:
— AWS: billing alert, charges 23% above last month (received 2h ago)
— GitHub: 3 PRs waiting on your review
— Client: Acme Corp asking for project status update (3 days old)
— 8 newsletters/digests (no action required)
You: Draft a reply to the Acme Corp email
Agent: Draft ready. I used your previous email tone — professional but
direct. Key updates included: timeline, current blockers, next
milestone. Review before sending? [Yes / Edit / Discard]
Limitation worth knowing: The send-on-behalf capability requires careful thought before enabling. The skill includes a confirmation step before any email is sent, which you should leave enabled. Disable it only if you're running a fully automated pipeline where you've reviewed the email templates in advance.
Discord
For developers involved in open-source communities, gaming, or teams that run on Discord, this skill is the equivalent of the Slack integration — but for Discord's server and channel structure.
What you can do with it:
- Post updates to specific channels
- Read channel history and thread conversations
- Monitor announcement channels for relevant news
- Send DMs to server members
- Post embeds with rich formatting
Install:
/skills install discord
Setup: Creates a bot user in your Discord server. You configure which channels the bot can read and write. The setup guide walks through the Discord developer portal steps — it takes about 5 minutes.
Usage examples:
You: Post the release notes to #releases
Agent: Posted to #releases with embed formatting.
Title: v2.3.0 Released
Body: [formatted changelog]
Pinged: @release-subscribers role
Best for: Maintainers of open-source projects who want to automate community announcements, or teams that have standardized on Discord over Slack.
Limitation worth knowing: Discord's rate limits are more aggressive than Slack's. If you're running batch notifications, add delays between messages or you'll hit 429 errors.
Telegram
Telegram is the lean option in this set. Lower setup friction than Slack or Discord, no OAuth flow required — just a bot token and a chat ID. If you want quick personal notifications without the overhead of a full workspace integration, Telegram is the right choice.
What you can do with it:
- Send yourself notifications from automated workflows
- Get alerts when long-running tasks complete
- Receive structured reports (daily summaries, build results)
- Two-way interaction via Telegram bot commands
Install:
/skills install telegram
Setup:
1. Message @BotFather on Telegram to create a bot
2. Copy your bot token
3. Run: /skills configure telegram --token YOUR_BOT_TOKEN --chat-id YOUR_CHAT_ID
Usage example:
You: Notify me on Telegram when the database migration finishes
Agent: I'll send you a Telegram message when the migration completes.
[45 minutes later — your phone buzzes]
"Migration complete. 847,293 rows processed. 0 errors. Duration: 41m 17s"
Limitation worth knowing: Telegram is great for personal notifications but not built for team coordination. Use it for your own workflow automation, Slack or Discord for team communication.
Choosing the Right Communication Skill
| Use case | Best skill |
|---|---|
| Team notifications and coordination | Slack |
| Email triage and drafting | Gmail |
| Open-source community management | Discord |
| Personal workflow notifications | Telegram |
| Multi-channel automated reporting | Slack + Telegram together |
The communication skills are where Claude Code transforms from an interactive tool into an autonomous participant in your workflow. When your agent can tell your team what it did, your team can start trusting it to do things unsupervised. That's the shift worth building toward.
