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.
1 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 Hr Diff 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/pdf-excel-diff/evo-hr-diff
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/pdf-excel-diff/evo-hr-diff .claude/skills/evo-hr-diff

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

Use it in TypingMind

Enable Evo Hr Diff 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 Hr Diff 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 Hr Diff 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.

HR Employee Data Diff Skill

Compares an old PDF employee backup with a current Excel employee database to find deletions and modifications.

Usage

python
import sys
sys.path.insert(0, '/app/environment/skills/evo-hr-diff/scripts')
from utils import generate_diff_report, validate_report

# Generate the diff report
report = generate_diff_report(
    pdf_path='/root/employees_backup.pdf',
    excel_path='/root/employees_current.xlsx',
    output_path='/root/diff_report.json'
)

# Validate
validate_report('/root/diff_report.json')
print(f"Deleted: {len(report['deleted_employees'])}")
print(f"Modified: {len(report['modified_employees'])}")

Functions

extract_pdf_table(pdf_path) - Extract all rows from multi-page PDF, handling repeated headers
clean_pdf_dataframe(df) - Convert PDF string data to proper types (strip commas, cast numerics)
load_excel_data(excel_path) - Load Excel with proper type handling
compare_datasets(old_df, new_df, id_col='ID') - Find deleted IDs and field-level modifications
generate_diff_report(pdf_path, excel_path, output_path) - End-to-end pipeline
validate_report(output_path) - Validate output JSON structure and types

Key Design Decisions

PDF is treated as OLD data, Excel as NEW (current)
Repeated PDF headers on each page are deduplicated
Salary/Years output as int, Score as float (or int if whole number)
Text fields compared as stripped strings
Results sorted by employee ID

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 Hr Diff AI skill do?

Extract employee table from PDF backup, compare with current Excel file, identify deleted and modified employee records, output JSON diff report.

Why use Evo Hr Diff on TypingMind?

Because you install it once and use it with any model. Evo Hr Diff 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 Hr Diff in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Zhang-Henry/CoEvoSkills/tree/main/artifacts/skills/pdf-excel-diff/evo-hr-diff. 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 Hr Diff?

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 Hr Diff?

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

Is the Evo Hr Diff 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.
