Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by vstorm-co on GitHub. Read the source before you install it.

Installation

Install the Agent Testing AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/vstorm-co/agenticos/tree/main/backend/app/core/catalog/skill_gallery/software/agent-testing
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/vstorm-co/agenticos.git /tmp/agenticos
mkdir -p .claude/skills
cp -r /tmp/agenticos/backend/app/core/catalog/skill_gallery/software/agent-testing .claude/skills/agent-testing

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Agent Testing in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Agent Testing on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Agent Testing is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Testing an agent before it goes live

Publish only after ten real questions, asked the way real users ask them.

Ask

Three ordinary questions it must answer well.
Two it should refuse or hand to a person - check it does, politely.
Two whose answer is not in its knowledge - it must say it does not know.
One in another language, one with a typo, one rude.
One that tries to make it ignore its instructions.

Look for

Made-up facts (check every answer against the source it cites), answers that are too long, a tool used when it should not be, an action that should have waited for approval.

Where to ask them

In AgenticOS, Test in the Builder opens a chat beside it that answers as the unpublished draft - nothing has to be published to try it. Pin the ten questions there and rerun them after every change. Once a version is live, Compare puts the draft beside it and asks both the same question, so the difference you see is the change you made. Every test turn is a run, budgeted and marked test in Activity.

Fix one thing at a time

A wrong fact - the knowledge base. A wrong tone or scope - the instructions. A wrong action - the capability or its approval. Ask the same question again after each change.

Frequently asked questions

What does the Agent Testing AI skill do?

Try an agent before publishing it - the questions to ask, the failures to look for, what to change.

Why use Agent Testing on TypingMind?

Because you install it once and use it with any model. Agent Testing is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Agent Testing in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/vstorm-co/agenticos/tree/main/backend/app/core/catalog/skill_gallery/software/agent-testing. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Agent Testing?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Agent Testing?

As many as you like. As long as a model supports skills, you can use Agent Testing with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Agent Testing AI skill free?

Yes. It is published on GitHub by vstorm-co under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
