threat-model-discover

threat-model-discover is a skill for Claude Code from RedHatProductSecurity/agentic-threat-modeling. It costs 42 tokens per session (2,870 once invoked), scanned A, original, Apache-2.0.

A skill that discovers the system context needed for threat modeling by examining code and, when appropriate, asking the user questions. It records components, data flows, trust boundaries, valuable assets, and possible entry points.

In plain words
What is it for?
Use it before threat analysis to inspect a codebase or supplied architecture materials and build a structured system profile.
Why use it?
A threat model is more useful when it reflects how the system actually works and where sensitive information or access crosses boundaries.

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-discover 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 10d 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.

The opening of the file, as written. The whole thing — 252 lines — stays where its author put it; the contents beside it link to each section on GitHub.

System Context Discovery

You are performing the discovery phase of threat modeling. Your job is to build a complete picture of the system being modeled — its components, how data flows, where trust boundaries exist, what assets matter, and where attackers can enter.

You operate in two modes. The dispatcher skill will tell you which to use.

Step 0: External Context Ingestion

If context: arguments were provided, split on commas and ingest each source. In guided or full mode, ask if there's anything else:

"Do you have any other external documentation I should ingest? Architecture docs, prior threat models, API specs, deployment diagrams, SBOMs, or SAR reports?"

If no context: arguments were provided and the mode is guided or full, ask the same question without "other." In quick mode, skip prompting entirely — just ingest any context: arguments and move on.

Supported external sources:

Source Type What's Extracted How to Provide
Google Docs / Confluence pages Architecture descriptions, component relationships, data flows Public URL, or paste/export content. Authenticated pages (behind SSO, Google login) require exporting first.
Mermaid / PlantUML diagrams Component topology, data flows, trust boundaries Paste content or provide file path
Prior threat models (THREAT_MODEL.md) Previously identified threats, accepted risks, implemented mitigations File path or URL
SAR reports (Security Assessment Reports) Previous findings, compliance status, remediation state File path or URL
OpenAPI / Swagger specs (YAML/JSON) Endpoints, auth schemes, data models, request/response shapes File path in repo or external
SBOM (CycloneDX or SPDX) Dependency inventory, known vulnerabilities, license risks File path
Product definition JSON Service catalog, ownership, dependencies File path
Deployment topology YAML Network segments, trust zones, cloud services, regions File path
Terraform / CloudFormation templates Infrastructure components, network rules, IAM policies, storage configs File path in repo or external
Kubernetes manifests / Helm values Pod security, network policies, RBAC, secrets management File path in repo or external

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.
