  • 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 Dependency Audit AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

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.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/Zhang-Henry/CoEvoSkills/tree/main/artifacts/skills/software-dependency-audit/evo-dependency-audit
  4. 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/Zhang-Henry/CoEvoSkills.git /tmp/CoEvoSkills
mkdir -p .claude/skills
cp -r /tmp/CoEvoSkills/artifacts/skills/software-dependency-audit/evo-dependency-audit .claude/skills/evo-dependency-audit
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Evo Dependency Audit 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 Dependency Audit 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 Dependency Audit 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.

Dependency Security Audit Skill

This skill scans npm package-lock.json files for known vulnerabilities using trivy's offline vulnerability database and produces a CSV audit report.

Key Concepts

  • Uses trivy filesystem scanner with offline DB (no network needed)
  • Filters by severity level (HIGH, CRITICAL by default)
  • Extracts CVSS scores from the severity source for coherent records
  • Deterministic output ordering and deduplication
  • Preserves missing fixed versions as "N/A"

Usage

python
import sys
sys.path.insert(0, '/app/environment/skills/evo-dependency-audit/scripts')
from utils import run_audit, validate_audit

# Run the full audit pipeline
rows = run_audit(
    lockfile_path='/root/package-lock.json',
    output_csv_path='/root/security_audit.csv',
    severity_levels=['HIGH', 'CRITICAL']
)
print(f"Found {len(rows)} vulnerabilities")

# Validate the output
validate_audit('/root/security_audit.csv')

Individual Functions

All functions are in scripts/utils.py:

  • run_trivy_scan(lockfile_path, severity_levels, output_json_path) - Run trivy scan
  • extract_vulnerabilities(trivy_data) - Extract vulns from trivy JSON
  • get_cvss_score(vuln) - Get CVSS score using coherent source priority
  • format_vulnerability_row(vuln) - Format a vuln into a CSV row dict
  • deduplicate_rows(rows) - Remove duplicate entries
  • sort_rows(rows) - Deterministic sorting by Package, CVE_ID
  • write_csv(rows, output_path) - Write CSV with proper headers
  • run_audit(lockfile_path, output_csv_path, severity_levels) - End-to-end entry point
  • validate_audit(csv_path) - Validate output CSV meets requirements

CSV Output Format

Columns: Package,Version,CVE_ID,Severity,CVSS_Score,Fixed_Version,Title,Url

CVSS Score Resolution

  1. Use the severity source (usually ghsa) for coherent record
  2. Fallback: ghsa -> nvd -> redhat -> any available
  3. Always use V3Score when available

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 Dependency Audit AI skill do?

Perform security audit on npm/node dependency lockfiles using trivy offline scanner. Identifies HIGH and CRITICAL vulnerabilities and produces a structured CSV report with package, version, CVE, severity, CVSS score, fixed version, title, and reference URL.

Why use Evo Dependency Audit on TypingMind?

Because you install it once and use it with any model. Evo Dependency Audit 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 Dependency Audit in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Zhang-Henry/CoEvoSkills/tree/main/artifacts/skills/software-dependency-audit/evo-dependency-audit. 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 Dependency Audit?

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 Dependency Audit?

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

Is the Evo Dependency Audit 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.
