security-requirement-extraction

security-requirement-extraction is a skill for Claude Code, Codex from RudyCity/superagent. It costs 37 tokens per session (488 once invoked), scanned A, original, MIT.

A guide for turning threat models and business context into specific security requirements. It connects risks to requirements, technical controls, tests, and acceptance criteria.

In plain words
What is it for?
Use it to write security user stories, map compliance needs, define security tests, and document security architecture requirements.
Why use it?
It helps prevent vague security goals by making them actionable and verifiable during development.

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

security-requirement-extraction 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 6d 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.

Security Requirement Extraction

Transform threat analysis into actionable security requirements.

When to Use This Skill

  • Converting threat models to requirements
  • Writing security user stories
  • Creating security test cases
  • Building security acceptance criteria
  • Compliance requirement mapping
  • Security architecture documentation

Core Concepts

1. Requirement Categories

Business Requirements → Security Requirements → Technical Controls
         ↓                       ↓                      ↓
  "Protect customer    "Encrypt PII at rest"   "AES-256 encryption
   data"                                        with KMS key rotation"

2. Security Requirement Types

Type Focus Example
Functional What system must do "System must authenticate users"
Non-functional How system must perform "Authentication must complete in <2s"
Constraint Limitations imposed "Must use approved crypto libraries"

3. Requirement Attributes

Attribute Description
Traceability Links to threats/compliance
Testability Can be verified
Priority Business importance
Risk Level Impact if not met

Best Practices

Do's

  • Trace to threats - Every requirement should map to threats
  • Be specific - Vague requirements can't be tested
  • Include acceptance criteria - Define "done"
  • Consider compliance - Map to frameworks early
  • Review regularly - Requirements evolve with threats

Don'ts

  • Don't be generic - "Be secure" is not a requirement
  • Don't skip rationale - Explain why it matters
  • Don't ignore priorities - Not all requirements are equal
  • Don't forget testability - If you can't test it, you can't verify it
  • Don't work in isolation - Involve stakeholders

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.
