The Blueprint
A blueprintis the complete spec sheet of your agent: its name, the Claude model it uses, the tools it has access to, the instructions it must follow. It's what the Builderconstructs for you throughout the conversation, and it's what Forgent sends to Anthropic Managed Agents at deployment time.
The essential fields
Name
Short (max 60 characters), descriptive, in any language. Used to find the agent in My Agents and shown in the Anthropic dashboard.
Description
One or two sentences summarizing what the agent does. It's the summary shown in the list — not the system prompt.
Model
The Claude model that runs the agent: claude-fable-5, Anthropic's most capable model. See Claude Fable 5 for the details.
Tools
The list of capabilities the agent has access to. A few standard tools:
read,write— reading / writing filesbash— running sandboxed shell commandsweb_search,web_fetch— searching and fetching web pagesMCP: notion,MCP: gmail, etc. — connectors to your external tools (see MCP & tools)
Tone
Influences both the voice of the agent (formal, warm, technical) and the format of its outputs (bullet points, tables, running prose). A subtle setting but one that changes the experience of a deliverable a lot.
System prompt
The heart of the blueprint: the complete instructions given to Claude. It's generated automatically by the Builder from your answers. You can view it before deployment and edit it manually if you know what you're doing — but in general, the generated prompt is better written than a human prompt because it's been optimized for Claude by Claude.
JSON format
Here's an example of a serialized blueprint. It's what you find in My Agents under View JSON, and it's portable:
{
"name": "Weekly competitive monitoring",
"description": "Watches 5 competitor sites and sends a summary every Monday.",
"model": "claude-fable-5",
"tools": ["web_fetch", "web_search", "write"],
"tone": "Clear and factual",
"system": "You are a competitive monitoring agent. Every Monday at 9am, you visit the 5 sites listed below, you identify what's new (new pages, blog posts, pricing changes) and you produce a structured markdown report...",
"schedule": "weekly",
"outputs": ["markdown"]
}Versions and history
Forgent keeps a history of the latest snapshots of your blueprint (persisted server-side, so it follows you across devices) and lets you restore an old version in the Builder. See Versions & detailed logs for the details.
