validate

Validate Copilot Studio agent YAML files using the LSP binary's full diagnostics (YAML structure, Power Fx, schema, cross-file references). Use when the user asks to check, validate, or verify YAML files.

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 microsoft on GitHub. Read the source before you install it.

Installation

Install the Validate 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/microsoft/skills-for-copilot-studio/tree/main/skills/validate
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

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/microsoft/skills-for-copilot-studio.git /tmp/skills-for-copilot-studio
mkdir -p .claude/skills
cp -r /tmp/skills-for-copilot-studio/skills/validate .claude/skills/validate

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

Use it in TypingMind

Enable Validate 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 Validate 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 Validate 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.

Validate Agent YAML

Validate Copilot Studio agent YAML files using the LanguageServerHost binary's full diagnostics — the same validation engine used by the VS Code Copilot Studio extension.

Instructions

Locate the agent workspace. Find the directory containing .mcs/conn.json. If a specific file was requested, use the workspace that contains it.

Run LSP-based validation:

bash
node ${CLAUDE_SKILL_DIR}/../../scripts/manage-agent.bundle.js validate \
  --workspace "<path-to-agent-folder>" \
  --tenant-id "<tenantId>" \
  --environment-id "<envId>" \
  --environment-url "<envUrl>" \
  --agent-mgmt-url "<mgmtUrl>"

This validates all .mcs.yml files in the workspace using the LSP binary's full diagnostics: YAML structure, Power Fx expressions, schema validation, cross-file references, and environment-specific checks.

Connection details come from .mcs/conn.json — read it to get tenant-id, environment-id, environment-url, and agent-mgmt-url.

Parse the JSON output:
- valid: true → all files pass (may still have warnings)
- valid: false + summary.errors > 0 → report errors as FAIL items
- summary.warnings > 0 → report as WARN items
- Each file with diagnostics is listed with severity, message, code, and line range
If the user asked about a specific file, filter the output to show only that file's diagnostics.

For additional context on specific errors, use schema lookup:

bash
node ${CLAUDE_SKILL_DIR}/../../scripts/schema-lookup.bundle.js resolve <kind>

Report findings:


Validation Results for: <agent-name>

[PASS] <filename> — no issues
[FAIL] <filename> — <error message> (line X)
[WARN] <filename> — <warning message> (line X)

Summary: X files checked, Y errors, Z warnings

Frequently asked questions

What does the Validate AI skill do?

Why use Validate on TypingMind?

Because you install it once and use it with any model. Validate 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 Validate in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/microsoft/skills-for-copilot-studio/tree/main/skills/validate. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Validate?

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 Validate?

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

Is the Validate AI skill free?

Yes. It is published on GitHub by microsoft under the MIT 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.
