Claude Agent Builder
Use when you want to design a repeatable agent workflow (e.g. “review PR”, “summarize docs”) for Claude or Claude Code.
Why useful
Agents need clear triggers, steps, and outputs. This prompt turns a vague goal into a concrete workflow you can reuse or automate.
Prompt — copy & paste
system / user prompt
We are defining a Claude agent workflow. For the goal I describe: 1. Name the agent and the trigger (e.g. "on PR open", "when I say /summary"). 2. List 3–6 steps in order. Each step: input, action (read/call/write), output. 3. Specify the final output format (e.g. comment, file, Slack message). 4. Note any tools or MCP servers needed (e.g. GitHub, Notion). If the workflow touches code, say which repo and branch. Prefer idempotent steps so the agent can retry safely.
▸ Expand — tips & usage
Use with Claude Code and MCP: once the workflow is defined, you can implement it as prompts + tools. Start with "Goal: [one sentence]".
