LOAD THIS SKILL when: writing unit tests, TRPC integration tests, or E2E tests. Covers Vitest patterns, Effect service testing, PGlite database testing, and Playwright E2E.
Guide for upgrading Stripe API versions and SDKs
Runs Fastly Compute WASM applications locally with Viceroy, specifically for Rust and Component Model projects. Use when starting a local Fastly Compute dev server with Viceroy, configuring fastly.toml for local backend overrides and store definitions, running Rust unit tests with cargo-nextest against the Compute runtime, debugging Compute apps locally, adapting core WASM modules to the Component Model, or troubleshooting local Compute testing issues (connection refused, missing backends, store config). For non-Rust Compute work or understanding the Compute API, prefer the fastlike skill instead — its source code is easier to understand as a Fastly Compute API reference.
Configures, manages, and debugs the Fastly CDN platform — covering service and backend setup, caching and VCL, security features like DDoS/WAF/NGWAF/rate limiting/bot management, TLS certificates and cache purging, the Compute platform, and the REST API. Use when working with Fastly services or domains, setting up edge caching or origin shielding, configuring security features, making Fastly API calls, enabling products, or looking up Fastly documentation. Also applies when troubleshooting 503 errors or SSL/TLS certificate mismatches on Fastly, and for configuring logging endpoints, load balancing, ACLs, or edge dictionaries.

Smart contract security best practices for Solidity development. Use when writing, reviewing, or auditing Solidity code. Covers reentrancy prevention, access control patterns, safe external calls, input validation, upgrade safety, and OWASP Smart Contract Top 10 vulnerabilities. Triggers on tasks involving security, vulnerability detection, access control, CEI pattern, ReentrancyGuard, SafeERC20, or smart contract auditing.
ERC token standard implementation guidelines for Solidity. Use when implementing, extending, or reviewing ERC20, ERC721, ERC1155, or ERC4626 contracts. Covers interface compliance, common pitfalls, OpenZeppelin and Solady implementations, extension patterns, and testing strategies. Triggers on tasks involving token implementation, NFT contracts, vault standards, or ERC compliance.
Adversarial scenario analysis and threat modeling for Solidity smart contracts. Use when analyzing contracts from an attacker's perspective, identifying multi-step attack vectors, or performing threat modeling. Covers flash loan attacks, oracle manipulation, MEV/front-running, governance exploits, reentrancy scenarios, access control bypasses, economic logic exploits, and cross-contract composability risks. Triggers on tasks involving adversarial analysis, threat modeling, attack scenarios, attack vectors, exploit analysis, or red team review.
Analyze Claude Code session transcripts to improve existing skills or create new ones. Use when you want to review a past session to identify what worked, what didn't, and how to enhance skill documentation. Extracts session data and provides structured analysis prompts. Triggers on "improve skill", "analyze session", "review session", "skill improvement", "create skill from session", "skill not working", "skill missed", "skill didn't trigger", "enhance skill", "refine skill", "skill feedback", "session transcript", "what went wrong", "skill optimization", "better triggers".
Reviews and improves English text for grammar, clarity, and tone while preserving the original intent. Tailored for non-native English speakers, especially Spanish speakers. Use when proofreading emails, Slack messages, reports, meeting notes, or presentation content.
Use when optimizing CLAUDE.md, AGENTS.md, custom commands, or skill files for Claude 4.5 models - applies documented Anthropic best practices systematically instead of inventing improvements
Use when answering complex questions about a codebase that require exploring multiple areas or understanding how components connect - coordinates parallel sub-agents to locate, analyze, and synthesize findings
