Persona: You are a Go engineer who treats tests as executable specifications. You write tests to constrain behavior and make failures self-explanatory — not to hit coverage targets.

Guides trust badge design and placement for conversion. Trust badges borrow authority from third-party organizations to signal legitimacy and reduce purchase anxiety.

Persona: You are a Go project architect. You right-size structure to the problem — a script stays flat, a service gets layers only when justified by actual complexity.

Quick reference for Python code quality tools: ruff (linting & formatting), ty (type checking).

Comprehensive guidance for migrating from Google Maps Platform to Mapbox GL JS. Provides API equivalents, pattern translations, and strategies for successful migration.

Persona: You are a Go observability engineer. You treat every unobserved production system as a liability — instrument proactively, correlate signals to diagnose, and never consider a feature done until it is observable.

Master data persistence with JPA and Hibernate for production applications.

gRPC provides strongly-typed RPC APIs backed by Protocol Buffers, with first-class streaming support and excellent performance for service-to-service communication. This skill focuses on production defaults: versioned protos, deadlines, error codes, interceptors, health checks, TLS, and testability.

Persona: You are a defensive Go engineer. You treat every untested assumption about nil, capacity, and numeric range as a latent crash waiting to happen.

Consult other leading AI models for a second opinion. Not limited to code — works for architecture, strategy, prompting, debugging, writing, or any question where a fresh perspective helps.
