Does it always build an agent?

No. If the task is a fixed sequence of steps, it builds a code-orchestrated workflow instead. The agent loop is reserved for multi-step tasks that are hard to specify in advance and where errors are recoverable.

What safety limits does it add?

Maximum iterations, tokens or cost per run, and a wall-clock timeout, all configurable and logged when hit. Hard-to-reverse actions such as sends, deletes and payments are gated behind explicit confirmation.

How does it check the agent works?

With 10-20 representative tasks, each with a programmatic check on the outcome. The suite runs on every prompt or tool change and tracks success rate, iterations and cost per task.

Building an AI agent

/ai--agent-builder

/ai--agent-builder is a Claude Code skill in the AI & Agents section. Designs and implements an LLM agent in your codebase: the loop, tools, memory, stop limits and a task-level eval suite to run before shipping.

Author's description

Build an AI agent - loop design, tool surface, memory, stop conditions, evals

Use it when

You have a multi-step task that is hard to fully specify up front
You want a model to call tools and keep iterating until it is done
You need cost and iteration limits plus tests before shipping

Not for

Fixed-sequence tasks, where code-orchestrated calls are enough
Coordinating several agents at once (that is what ai--multi-agent is for)

What you get

Agent code in your repository (loop, tools, stop limits, logging) plus a suite of 10-20 test tasks, each with an automatic pass/fail check.

How to ask for it

/ai--agent-builder design an agent that handles support tickets
/ai--agent-builder help me define stop conditions for my agent
/ai--agent-builder what tools should I expose to this agent?

Install
