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

Installation

Install the Evo Supply Shock 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/Zhang-Henry/CoEvoSkills/tree/main/artifacts/skills/shock-analysis-supply/evo-supply-shock
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/Zhang-Henry/CoEvoSkills.git /tmp/CoEvoSkills
mkdir -p .claude/skills
cp -r /tmp/CoEvoSkills/artifacts/skills/shock-analysis-supply/evo-supply-shock .claude/skills/evo-supply-shock

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

Use it in TypingMind

Enable Evo Supply Shock 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 Evo Supply Shock 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 Evo Supply Shock 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.

Supply-Side Shock Analysis Skill

Overview

This skill implements a complete workflow for estimating the impact of an investment spending shock on a small open economy using:

Data collection from PWT (capital stock), IMF WEO (GDP), and ECB (CFC)
HP filter for trend extraction in Excel
Cobb-Douglas production function for potential GDP estimation
Investment shock modeling

Usage

python
import sys
sys.path.insert(0, '/app/environment/skills/evo-supply-shock/scripts')
from data_collection import collect_pwt_data, collect_weo_data, collect_ecb_cfc_data
from excel_builder import build_supply_model
from validator import validate_workbook

# End-to-end entry point
build_supply_model(
    template_path='/root/test-supply.xlsx',
    output_path='/root/test-supply.xlsx'
)

# Validate
validate_workbook('/root/test-supply.xlsx')

Workflow Steps

Data Collection: Download PWT, WEO, ECB data programmatically
Populate PWT Sheet: Fill rnna and rgdpna columns
Populate WEO Sheet: Fill real GDP level and growth rate, extend to 2043
Populate CFC Sheet: Fill CFC data, link capital stock, calculate depreciation
Production Sheet: Set up HP filter formulas, production function
Run LibreOffice Solver: Optimize HP filter via macro
Validate: Check formulas and results

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 Evo Supply Shock AI skill do?

Why use Evo Supply Shock on TypingMind?

Because you install it once and use it with any model. Evo Supply Shock 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 Evo Supply Shock in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Zhang-Henry/CoEvoSkills/tree/main/artifacts/skills/shock-analysis-supply/evo-supply-shock. 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 Evo Supply Shock?

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 Evo Supply Shock?

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

Is the Evo Supply Shock AI skill free?

Yes. It is published on GitHub by Zhang-Henry 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.
