Blockchain Protocol Security Audit Preparation
Document threat models and attack surfaces for blockchain audit prep
What You Can Do
You can systematically document threat models, map attack surfaces, and articulate security assumptions for your blockchain protocol—all critical deliverables auditors expect. This skill guides you through building comprehensive security documentation that demonstrates you've thought deeply about potential vulnerabilities and risks before audit teams arrive. You'll create audit-ready artifacts that accelerate the audit process and help identify gaps in your security posture early.
Features
Identify and document potential attack vectors and threat actors relevant to your protocol
Create comprehensive diagrams showing external interfaces, dependencies, and potential entry points
Document explicit assumptions about the security environment, trust models, and dependencies
Categorize findings using standard frameworks (CVSS, severity matrices)
Quantify likelihood and impact to prioritize remediation efforts
Verify all audit deliverables are documented and complete before submission
Generate clear diagrams and descriptions of your protocol's security design
Example Output
Threat Model Example
Threat Actor: External attacker with access to node infrastructure Attack Vector: Network-level eclipse attack isolating validator Impact: Temporary consensus disruption Mitigation: Peer diversity requirements + connection limits
Attack Surface Mapping
External Entry Points:
├─ RPC endpoints (read-only, authenticated)
├─ P2P network (permissionless gossip protocol)
└─ Consensus layer (stake-weighted voting)
Internal Components at Risk:
├─ Transaction validation (custom WASM VM)
├─ State storage (encrypted key-value store)
└─ Network messaging (Ed25519 signatures)
Security Assumptions Document

You can accelerate your entire antenna design workflow—from initial concept to optimized specifications—by leveraging Claude's knowledge of electromagnetic theory, antenna types, and design trade-offs. Claude helps you parameterize designs, identify optimal configurations for your frequency band and application, and prepare detailed briefs for simulation and manufacturing. You'll generate design reviews, impedance-matching solutions, and validation checklists without context-switching to multiple tools.
You can convert raw API code, OpenAPI specs, GraphQL schemas, and implementation details into production-ready reference documentation. The skill generates systematically organized endpoint documentation with parameter tables, real request/response examples, error code catalogs, authentication details, rate limits, and SDK usage snippets in multiple programming languages—creating the authoritative developer reference for REST APIs, GraphQL APIs, WebSocket APIs, and webhook schemas.
Rapidly analyze production incidents by correlating observability signals—logs, metrics, traces, and events—to identify the true root cause instead of symptoms. You'll reconstruct incident timelines, quantify impact scope, and generate both immediate remediation steps and long-term prevention measures.
This skill guides you through designing Kalman filters for your specific state estimation and sensor fusion problems. You'll learn to diagnose filter divergence, tune covariance matrices (Q and R), and validate observability—turning mathematical theory into production-ready filters. The skill provides step-by-step workflows, diagnostic tools, and practical templates for common applications like GPS/IMU fusion, SLAM, and aircraft navigation.
Claude analyzes your code diffs and generates standardized commit messages that follow the Conventional Commits specification. The skill automatically determines the correct commit type, scope, and description based on the changes you've made, ensuring your messages are parseable by automation tools while remaining human-readable for code reviewers.
You'll transform high-level feature requirements into a complete development plan covering API design, frontend implementation, testing strategy, and documentation. The skill helps you identify dependencies, parallelize work across frontend and backend teams, and establish quality gates that ensure features ship bug-free with proper error handling and logging.
You get a comprehensive security and gas optimization review of your Solidity smart contracts. The skill identifies common vulnerabilities like reentrancy attacks, overflow/underflow bugs, and unchecked external calls, while also pinpointing expensive operations and suggesting specific gas optimizations. Use this as a pre-audit screening to catch issues early and prepare your code for professional security review.
You can rapidly design, optimize, and validate chromatographic and LC-MS/MS methods for analyzing drugs and metabolites in biological matrices. This skill guides you through analytical method development workflows—including parameter selection, sensitivity optimization, and regulatory strategy—while ensuring ICH Q2(R2) and FDA compliance throughout the development process.
