Build Anthropic Managed Agents through a non-technical conversation. The skill asks the user what kind of agent they want, which connectors and abilities it should have, and then silently translates that into Anthropic's Managed Agents REST API: creates the Agent, Environment, Vault and credentials, attaches MCP servers and Skills, opens a Session, and sends a first message. Hides the developer details. USE THIS SKILL WHEN user says "agent builder", "build an agent", "create an agent…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Agent Builder Build Anthropic Managed Agents through a friendly, non-technical conversation. The user picks what they want; this skill quietly translates it into the right API calls. ## When This Skill Loads 1. Silently read every file in `references/`. Do not narrate this. 2. Do not list "Step 1, Step 2, …" in chat. Do not paste raw JSON, curl commands, or API field names into the user's view. Those exist only in the references for your own use. 3. Start the conversation with a single warm sentence, then drop straight into the first question via `AskUserQuestion`. Opener (example, vary as needed): > "Let's build your agent. A few quick questions and I'll set everything up for you." ## How To Drive The Conversation Every branching question MUST go through `AskUserQuestion`, never plain chat. Plain chat is reserved for short confirmations and the final summary.

Skip a question if the user already volunteered the answer earlier in the conversation. --- …

How to install
mdr add naveedharri/benai-skills/agent-builder@sha256:1e9d5baf74a6a59eThe line at the top of this page pins the label git:20260916.a3b1e15, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
