Build An AI Agent In 10 Minutes, No Code

Before managed agents launched, building an AI agent meant learning a complicated no code tool, engineering the whole thing from scratch in Claude Code, or wrestling with something complicated and unsecure like OpenClaw. Now you go to platform.claude.com, describe what you want in plain English, connect your accounts through the built in credential vault, and Claude builds the entire thing for you.

What You'll Learn

• What managed agents actually are and why they beat the old options
• The 4 step setup: dashboard, describe, connect, test
• A copy paste inbox triage agent prompt
• 4 other agents to build today, with full prompts

Old Way Vs New Way

• Old way: Zapier or n8n. Visual canvas, manual rule setup, monthly subscription, cannot make judgment calls
• Old way: build from scratch in Claude Code. Full engineering project, hosting required, credential management, monitoring
• Old way: OpenClaw and similar. Complicated configuration, unsecure credential handling, most people give up
• New way: platform.claude.com. Describe in plain English, built in vault handles OAuth, Anthropic hosts everything, 5 to 10 minute setup

Step 1: Go To The Dashboard

Open your browser and go to:

https://platform.claude.com/workspaces/default

Click managed agents in the sidebar, then click Quickstart to build your first agent.

Step 2: Describe The Agent

This is the inbox triage agent prompt. Copy, paste, and adjust for your own inbox:

I want to build an inbox triage agent. Every morning I lose an hour sorting through
emails instead of doing real work.

What the agent should do:
1. Run every hour during business hours
2. Connect to my Gmail via MCP
3. Read new emails since the last run
4. Classify each email into one of four buckets: hot lead, support request, invoice,
or noise
5. For hot leads, draft a reply in my voice (I will give you 3 example replies I
have written)
6. File support requests with a Support label
7. File invoices with an Invoices label and extract the amount
8. Mark noise as read and archive it
9. Send me one Slack message summarizing the run: 'Your inbox is handled. [X] hot
leads waiting, [Y] drafts ready, [Z] handled.'
10. Never send anything automatically, always wait for me to review drafts

Connect Gmail MCP and Slack MCP. Use my existing credentials through the vault.

Step 3: Connect Your Accounts

When Claude asks you to connect Gmail and Slack, click connect. Anthropic's built in credential vault handles OAuth automatically. You never touch an API key. Approve the connection once and it is stored securely in your workspace.

Step 4: Test Before Deploying

Click test run in the dashboard. Claude executes one session and shows you exactly what it did. Review the output. Tell Claude what to adjust. Iterate until it matches your judgment. Then deploy.

4 Other Agents To Build Today

1. Weekly competitor monitor

Build an agent that runs every Monday morning. Visit these 5 competitor websites,
compare them to last week's snapshot, and send me a Slack message summarizing what
changed - new features, pricing updates, blog posts, hiring pages. Use the Firecrawl
MCP for scraping.

2. Invoice processor

Build an agent that runs every 6 hours. Read my Gmail inbox, find emails with PDF
invoices attached, extract vendor name, amount, due date, and line items, then add a
new row to my Google Sheets bookkeeping tracker.

3. Content repurposer

Build an agent that checks my blog RSS feed every day. When a new post is published,
draft a Twitter thread, a LinkedIn post, and a newsletter blurb. Save them all to a
Notion page. Match my writing style by analyzing my last 10 posts first.

4. Meeting notes to tasks

Build an agent that watches my Otter folder for new meeting transcripts. When a new
transcript lands, extract action items and assignees, create tasks in ClickUp with
due dates, and send a Slack message summarizing the meeting.

Why This Beats Everything Else

• Faster than n8n or Zapier: describe in plain English vs configuring 20 visual nodes. 5 to 10 minute setup vs 1 to 2 hours
• Cheaper than subscriptions: uses existing Anthropic credits vs $20 to $99/month Zapier or Make subscriptions
• More effective than rule based tools: agents make judgment calls, not just rules
• More secure than self hosted setups: Anthropic hosts everything, built in credential vault, no API keys in config files
• Zero technical experience required: the real unlock. Anyone can build automation now

Iteration Tips

• Start with one agent and run it manually for a week before scheduling. Build trust in the output first
• Add 3 to 5 example outputs to the system prompt. The agent matches your judgment much more closely
• For anything that sends external communication, have the agent draft only and wait for your approval
• Use the debug view to see every tool call and reasoning step
• Cost per run is usually a few cents. Do not over optimize until you have a working agent
• The built in credential vault is the unlock. Never hard code API keys anywhere
