Build a custom support agent for the messy middle of your business: plain-English instructions plus approved tools that merge duplicate tickets, open Jira, notify Slack and update customers: AI agent prompt
Zendesk's Oct 15, 2026 post (and Anthropic's Zendesk customer story) reports Custom Agents powered by Claude reached 1 million executions in the first seven weeks of early access. A five-person team built the Custom Agent Builder with Claude Code and the Claude Agent SDK in about four months, running Claude via Amazon Bedrock. Customers write plain-English instructions and connect approved tools. One highlighted workflow: when many customers report the same issue, the agent groups related tickets, opens a Jira issue, notifies engineers on Slack, updates customers, then closes related tickets with an explanation when fixed. Early customers reported up to 10% higher automated resolution and up to 80% lower human handle times; one pilot hit 99% accuracy on duplicate-ticket merging.
The prompt
Design a Zendesk-style Custom Agent for [my company]. Channel: [chat/email/voice]. Workflow to automate: [e.g. duplicate-ticket merge / warranty claim / billing dispute / multi-ticket incident]. Systems it may use: [Zendesk, Jira, Slack, CRM]. Hard rules: list every allowed tool action; never invent policy; escalate [fraud, legal, VIP] to a human; log every tool call. 1) Write the plain-English agent instructions (role, tone, steps). 2) List read vs write permissions per system. 3) Draft the happy path and 8 failure/escalation cases. 4) Propose a pilot metric set (automated resolution, handle time, accuracy on [task]).

Before you use it: what to check
Already built into this prompt
- Do not connect to live systems in this chat.
Check yourself
- This prompt works on text other people wrote (emails, reviews, messages or web pages). That text can hide instructions aimed at AI, such as "ignore your rules and…". Paste it as material to work on, and never let the AI act on requests inside it, like paying, sharing logins or changing records. How prompt injection works →
- Anything legal, tax or compliance-related is a first draft for a qualified person to check. It is not professional advice, and clause references and deadlines must be checked against the source.
- Remove names, contact details, account numbers and other personal data the task doesn't need before you paste, and check your AI tool's data and training settings.
- Read and edit the draft before it reaches a customer or goes public. If you later automate this prompt, start with "draft and notify me", not "send automatically".
