Proverif Tamarin Protocol Modeling

Q: What is a Claude Code skill and how does the Proverif Tamarin Protocol Modeling skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Proverif Tamarin Protocol Modeling is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.

ai:agent

Formal protocol verification with ProVerif and Tamarin Prover for multi-agent coordination systems. Use when modeling secrecy properties (escrow opacity, session note confidentiality), replay resistance (token dismissal finality, backup-restore attacks), delegation chain correctness, or append-only log integrity in applied pi calculus. Use when deciding between ProVerif and Tamarin for a given property. Use when extending existing .pv models (e.g., harbor_card_v3_delegation.pv) with new security queries. NOT for general cryptography tutorials, TLS certificate management, key management operations (rotation, storage, HSM integration), or smart contract verification (use Solidity-specific tools).

Prove it symbolically or admit you are guessing. The Dolev-Yao attacker controls the network. Your job is to define what that attacker cannot do, then ask the prover to confirm.

What this skill does

Proverif Tamarin Protocol Modeling is a community-contributed Claude Code skill in the appsec-build sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/proverif-tamarin-protocol-modeling/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when modeling secrecy properties (escrow opacity, session note confidentiality), replay resistance (token dismissal finality, backup-restore attacks), delegation chain correctness, or append-only log integrity in applied pi calculus.
