Threat Model Generation

Generate or refresh a STRIDE-based threat model for the current repository using Bug Hunter-native artifacts. Use whenever the repository has no threat model yet, the architecture changed materially, a security review needs fresh trust-boundary context, or the user explicitly asks for a threat model.

  • 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 Threat Model Generation 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/threat-model-generation
  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/threat-model-generation .claude/skills/threat-model-generation
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Threat Model Generation 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 Threat Model Generation 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 Threat Model Generation 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.

Threat Model Generation

This is a bundled local Bug Hunter companion skill. It generates portable threat-model artifacts under .bug-hunter/.

Purpose

Create the security context that the other security skills depend on:

  • trust boundaries
  • major components
  • STRIDE threats
  • vulnerability pattern library
  • severity/config defaults

Required outputs

Write:

  • .bug-hunter/threat-model.md
  • .bug-hunter/security-config.json

Workflow

  1. Read .bug-hunter/triage.json if available for file structure and domain hints.
  2. Inspect the repository to identify:
    • languages and frameworks
    • public/authenticated/internal entry points
    • data stores and external integrations
    • sensitive assets and trust boundaries
  3. Generate a concise STRIDE threat model.
  4. Generate a matching security config with thresholds and tech-stack metadata.

Compatibility

prompts/threat-model.md is generated from this skill for older clients. This skill is the canonical source and must be edited instead of the generated compatibility prompt.

Output rules

  • Keep the threat model short enough for downstream agents to consume.
  • Be specific about trust boundaries and vulnerable code patterns.
  • Keep all artifacts under .bug-hunter/, never .factory/.

Frequently asked questions

What does the Threat Model Generation AI skill do?

Generate or refresh a STRIDE-based threat model for the current repository using Bug Hunter-native artifacts. Use whenever the repository has no threat model yet, the architecture changed materially, a security review needs fresh trust-boundary context, or the user explicitly asks for a threat model.

Why use Threat Model Generation on TypingMind?

Because you install it once and use it with any model. Threat Model Generation 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 Threat Model Generation in TypingMind?

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

Which AI models can use Threat Model Generation?

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 Threat Model Generation?

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

Is the Threat Model Generation 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.
