Validate security findings for exploitability, reachability, and real-world impact using Bug Hunter-native findings artifacts. Use after security scans, before patch generation, or whenever the user wants confirmation that a suspected vulnerability is actually exploitable.

  • 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 codexstar69 on GitHub. Read the source before you install it.

Installation

Install the Vulnerability Validation 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/codexstar69/bug-hunter/tree/main/skills/vulnerability-validation
  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/codexstar69/bug-hunter.git /tmp/bug-hunter
mkdir -p .claude/skills
cp -r /tmp/bug-hunter/skills/vulnerability-validation .claude/skills/vulnerability-validation
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Vulnerability Validation 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 Vulnerability Validation 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 Vulnerability Validation 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.

Vulnerability Validation

This is a bundled local Bug Hunter companion skill. It strengthens the security-specific parts of the Skeptic/Referee process.

Purpose

Take suspected or confirmed security findings and answer:

  • Is the vulnerable path reachable?
  • Can an attacker control the input?
  • Are there existing mitigations?
  • How exploitable is it really?
  • What is the CVSS / PoC / impact level?

Inputs

Prefer Bug Hunter-native artifacts:

  • .bug-hunter/hunter-findings.json
  • .bug-hunter/threat-model.md
  • .bug-hunter/security-config.json
  • .bug-hunter/dep-findings.json when dependency issues are involved

Workflow

  1. Read the findings and isolate the security ones.
  2. Trace reachability:
    • EXTERNAL
    • AUTHENTICATED
    • INTERNAL
    • UNREACHABLE
  3. Trace exploitability:
    • EASY
    • MEDIUM
    • HARD
    • NOT_EXPLOITABLE
  4. Check for mitigations already present in code, framework behavior, or deployment assumptions.
  5. For confirmed HIGH/CRITICAL security bugs, generate:
    • exploitation path
    • benign proof of concept
    • CVSS vector + score
  6. Feed the result back into Bug Hunter-native verdicting.

Outputs

When used as a companion to the main pipeline, keep outputs compatible with:

  • .bug-hunter/referee.json
  • .bug-hunter/report.md

If a separate validation artifact is helpful for the run, place it under .bug-hunter/validated-findings.json.

Important constraints

  • This skill validates findings; it does not replace the normal fix pipeline.
  • Keep outputs portable and self-contained under .bug-hunter/.
  • Prefer explicit reasoning for false positives so the user can trust dismissals.

Frequently asked questions

What does the Vulnerability Validation AI skill do?

Validate security findings for exploitability, reachability, and real-world impact using Bug Hunter-native findings artifacts. Use after security scans, before patch generation, or whenever the user wants confirmation that a suspected vulnerability is actually exploitable.

Why use Vulnerability Validation on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/codexstar69/bug-hunter/tree/main/skills/vulnerability-validation. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Vulnerability Validation?

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 Vulnerability Validation?

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

Is the Vulnerability Validation AI skill free?

Yes. It is published on GitHub by codexstar69 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.
