threat-model-generation

threat-model-generation is a skill for Claude Code, Codex from codexstar69/bug-hunter. It costs 59 tokens per session (326 once invoked), scanned A, original, MIT.

A workflow for creating a STRIDE threat model, a security review that examines threats such as spoofing, tampering, and unauthorized disclosure. It records the repository's components, trust boundaries, security settings, and likely vulnerability patterns.

In plain words
What is it for?
It helps inspect a repository's languages, frameworks, entry points, data stores, integrations, and sensitive assets, then writes threat-model and security-configuration files under .bug-hunter.
Why use it?
It gives other security reviews a current map of how the system is structured and where data or control crosses between trusted and untrusted areas.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

threat-model-generation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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/.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
