Build agents with the Mastra framework

This skill guides building with Mastra, a TypeScript framework for building agents and workflows with tools, memory, and storage. It tells the agent to check current docs and APIs rather than rely on memory, and it helps with setup, frequent errors, version migrations, and the mastra api CLI.

Evaluate an ADK agent with agents-cli

This skill runs and reads evaluations for Google ADK (Agent Development Kit) agents, through the agents-cli eval commands. It walks a loop of preparing a dataset, running the eval, studying failures, and fixing the agent, then repeating. It also helps pick metrics, including LLM-as-judge scoring, and lists usual reasons a score drops.

FAQ

What is an ai agent skill?

An agent skill is a portable pack of instructions that gives an agent specialized know-how for a task. In the open Agent Skills format (from Anthropic, now widely adopted), that pack is a folder with a SKILL.md file and optional scripts or references the agent can load when needed.

What is a SKILL.md file?

SKILL.md is the required main file in a skill folder. It starts with simple metadata (name and description) plus the instructions. Agents use the metadata to decide when a skill applies, then read the full file — and any linked files — only when the task needs them.

How do I use a skill from this directory?

Open the listing and follow the source link — usually a GitHub SKILL.md. Install with your agent’s skill flow, or add the repo the way that product documents. When this site shows the skill text, Copy is on the page.

What’s the difference between a skill and a prompt?

A prompt is paste-in text for one chat turn (or a short thread). A skill is a reusable file pack an agent can discover and load across a task, sometimes with code attached. Prompts live in the prompt directory; skills usually live on GitHub and we link out.

How are skills categorized?

Each skill uses one sitewide category — the same set as the rest of the directory (Coding agent, Marketing, Document intelligence, and so on). Hops filter to categories that already have skills.

Can I submit a skill?

Yes. Submit with a public GitHub SKILL.md URL, or attach a skill as part of a method on a use case. An editor reviews it before it appears here.
