ai-sdk-agents SKILL.md skillA
ai-sdk-agents from bjornmelin/dev-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Expert guidance for building AI agents with ToolLoopAgent (AI SDK v6+). Use when creating agents, configuring stopWhen/prepareStep, callOptionsSchema/prepareCall, dynamic tool selection, tool loops, or agent workflows (sequential, routing, evaluator-optimizer, orchestrator-worker). Triggers: ToolLoopAgent, agent loop, stopWhen, stepCountIs, prepareStep, callOptionsSchema, prepareCall, hasToolCall, InferAgentUIMessage, agent workflows.
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
# AI SDK Agents
Build autonomous agents with ToolLoopAgent: reusable model + tools + loop control.
## Quick Start
Assume Zod v4.3.5 for schema typing.
```ts
import { ToolLoopAgent, tool } from 'ai';
import { anthropic } from '@ai-sdk/anthropic';
import { z } from 'zod';
const weatherAgent = new ToolLoopAgent({
model: anthropic('claude-sonnet-4-20250514'),
tools: {
weather: tool({
description: 'Get the weather in a location (F)',
inputSchema: z.object({ location: z.string() }),
execute: async ({ location }) => ({ location, temperature: 72 }),
}),
},
});
const result = await weatherAgent.generate({
prompt: 'What is the weather in San Francisco?',
});
```
## When to Use ToolLoopAgent vs Core Functions
- Use **ToolLoopAgent** for dynamic, multi-step tasks where the model decides which tools to call.
- Use **generateText/streamText** for deterministic flows or strict ordering.
## Essential Patterns
### Structured Output
```ts
import { ToolLoopAgent, Output } from 'ai';
import { z } from 'zod';
const analysisAgent = new ToolLoopAgent({
model: 'openai/gpt-4o',
output: Output.object({
schema: z.object({

How to install
mdr add bjornmelin/dev-skills/ai-sdk-agents@sha256:81e47fda468f64bbThe line at the top of this page pins the label git:20260512.8418464, 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.
