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.
6 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by JBurlison on GitHub. Read the source before you install it.

Installation

Install the Agent File Specs 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/JBurlison/WoWAddonAPIAgents/tree/main/skills/agent-file-specs
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/JBurlison/WoWAddonAPIAgents.git /tmp/WoWAddonAPIAgents
mkdir -p .claude/skills
cp -r /tmp/WoWAddonAPIAgents/skills/agent-file-specs .claude/skills/agent-file-specs

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

Use it in TypingMind

Enable Agent File Specs 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 File Specs 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 File Specs 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.

AI Coding Assistant Customization File Specifications

This skill provides the authoritative, up-to-date specifications for all AI coding assistant customization file types. Each file type has its own dedicated reference document with complete attribute tables, validation rules, examples, and best practices.

Standard: These specs align with the Agent Skills open standard and the VS Code Copilot customization documentation.

How to Use This Skill

Read the Quick Reference below to identify the file type you need.
Follow the link to the dedicated reference document for full details.
Use the File Locations reference when you need to know where files go for a specific provider.
Use the Settings reference for VS Code configuration.

Important: Detailed specifications live in the references/ folder — not in this file. This keeps the main skill file lightweight for efficient context loading per the progressive disclosure model.

Quick Reference

Type	Extension	Purpose	Reference
Agent	`.agent.md` / `.md`	Custom AI personas with specialized behaviors, tool restrictions, and handoff workflows	AGENTS.md
Skill	`SKILL.md` (directory-based)	Reusable, portable capabilities with scripts and resources — follows the Agent Skills open standard	SKILLS.md
Prompt	`.prompt.md`	Reusable prompt templates invoked as slash commands	PROMPTS.md
Instruction	`.instructions.md`	Contextual guidance applied automatically by file type or description	INSTRUCTIONS.md
File Locations	—	Provider folder mapping, directory structure, naming conventions	FILE-LOCATIONS.md
VS Code Settings	—	Settings that control customization file discovery and behavior	SETTINGS.md

Provider support

Shared SKILL.md content is portable; agents, rules, prompts, settings and plugin discovery are host-specific. This maintenance skill is not bundled with the WoW plugin. Use FILE-LOCATIONS.md for this repository's source/package mapping. The detailed agent/instruction/prompt examples are Copilot-oriented and are not universal host schemas.

File Type Selection Guide

Use this decision tree to choose the right file type:

"I want coding standards applied everywhere" → Use always-on instructions (.github/copilot-instructions.md or AGENTS.md). See INSTRUCTIONS.md.
"I want different rules for different file types" → Use file-based instructions (.instructions.md with applyTo patterns). See INSTRUCTIONS.md.
"I have a reusable task I run repeatedly" → Use a prompt file (.prompt.md) invoked as a slash command. See PROMPTS.md.
"I need a multi-step workflow with scripts and resources" → Use an Agent Skill (directory with SKILL.md). Portable across tools. See SKILLS.md.
"I need a specialized AI persona with tool restrictions" → Use a custom agent (.agent.md). Supports handoffs for multi-step workflows. See AGENTS.md.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Agent File Specs AI skill do?

Why use Agent File Specs on TypingMind?

Because you install it once and use it with any model. Agent File Specs 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 File Specs in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/JBurlison/WoWAddonAPIAgents/tree/main/skills/agent-file-specs. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Agent File Specs?

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 File Specs?

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

Is the Agent File Specs AI skill free?

Yes. It is published on GitHub by JBurlison 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.
