Use this skill whenever modifying DiffViewer.tsx, upgrading the @pierre/diffs package, changing unsafeCSS injection, adding new props to FileDiff, or touching shadow DOM selectors or CSS variables that cross into Pierre's shadow boundary. Also trigger when someone asks "will this break the diff viewer", "is this safe to change", or when reviewing PRs that touch the review-editor package.
Build throwaway code that answers a question, whether an interactive state model you can drive, a script that measures one thing, or competing live UI variants to switch between in the app, then fold the answer into the decision and delete the code. Use when the user says "prototype this", "spike this", "does this state model hold up", "is this library fast enough", or "try three live versions in the app". Not a demo generator and never production code.
Write production-grade Rust code using a multi-pass approach. Design types first, then implement, then simplify, then verify with automated lint. Use this skill whenever writing new Rust functions, structs, modules, or features. Triggers on Rust implementation, new Rust code, Rust functions, Rust modules, error handling in Rust, async Rust, or type design in Rust.
Perform language- and framework-specific security best-practice reviews and suggest improvements. Trigger only when the user explicitly requests security best-practice guidance, a security review/report, or secure-by-default coding help.

Keywords voxel, sandbox, cellular automata, MultiMesh, chunk management, emergent behavior, creative mode.
GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully.
Use when the user wants to design, redesign, shape, critique, audit, polish, clarify, distill, harden, optimize, adapt, animate, colorize, extract, or otherwise improve a frontend interface. Covers websites, landing pages, dashboards, product UI, app shells, components, forms, settings, onboarding, and empty states. Handles UX review, visual hierarchy, information architecture, cognitive load, accessibility, performance, responsive behavior, theming, anti-patterns, typography, fonts, spacing, layout, alignment, color, motion, micro-interactions, UX copy, error states, edge cases, i18n, and reusable design systems or tokens. Also use for bland designs that need to become bolder or more delightful, loud designs that should become quieter, live browser iteration on UI elements, or ambitious visual effects that should feel technically extraordinary. Not for backend-only or non-UI tasks.

Use when the user wants to produce installable artifacts without EAS (for e2e testing, sharing a build with a teammate, or quick iteration on a real device/simulator). Generates two shell scripts wired up to the user's actual app name, scheme, and bundle identifier.
Designs and implements REST and GraphQL APIs for Magento 2. Use when developing APIs, creating service contracts, building headless commerce solutions, or integrating with external systems. Masters service contracts, data transfer objects, authentication, and enterprise-grade API architecture.
Use this skill when an agent needs to write reusable code, store it in the configured Hermes Code folder, run it directly through local code execution, or host it behind a Make-managed E2B Code Shell scenario. Use for tool building, generated business automation scripts, and nested flows where hosted code calls Make API shell scenarios for SaaS access without receiving raw OAuth, Make, or E2B secrets.
