Go programming language skill for writing idiomatic Go code, code review, error handling, testing, concurrency, security, and program design. Use when writing Go code, reviewing Go PRs, debugging Go tests, fixing Go errors, designing Go APIs, implementing security-sensitive code, handling user input, authentication, sessions, cryptography, or asking about Go best practices. Covers table-driven tests, error wrapping, goroutine patterns, interface design, generics, iterators, stdlib patterns up to Go 1.26, and OWASP security practices.
Review error handling, input validation, and exception patterns using 24-item checklist. Use when auditing defensive code, designing barricades, choosing assertion vs error handling, or deciding correctness vs robustness strategy. Triggers on: empty catch blocks, missing input validation, assertions with side effects, wrong exception abstraction level, garbage in garbage out mentality, deadline pressure to skip validation, trusted source rationalization. Produce status table with VIOLATION/WARNING/PASS per item, or barricade/error-handling design recommendations.
JavaScript language fundamentals. Covers ES6+, modules, async patterns. Use when working with plain JS projects without TypeScript. USE WHEN: user mentions "javascript", "ES6", "async/await", "promises", "modules", asks about "destructuring", "spread operator", "arrow functions", "ESM vs CommonJS" DO NOT USE FOR: TypeScript projects - use `typescript` skill instead DO NOT USE FOR: Node.js runtime - use `nodejs` skill instead DO NOT USE FOR: Browser APIs - use framework-specific skills
Configure transaction isolation levels to prevent race conditions and handle concurrent access. Use when dealing with concurrent updates, financial operations, inventory management, or when users mention race conditions, dirty reads, phantom reads, or concurrent modifications.
Search, order, and manage phone numbers by location, features, and coverage.
Cancel an existing hotel booking. Use this skill when the user explicitly wants to cancel their reservation — phrases like "cancel my booking", "cancel reservation BK_xxx", "I don't need the hotel anymore", "refund my booking". This is a destructive action; always confirm with the user before calling, and warn if the cancellation is past the free-cancellation deadline.
This skill should be used when designing Make scenarios, choosing which modules to use, composing module flows, setting up routing/branching/filtering/iterations/aggregations, building blueprints, deploying scenarios, handling errors, configuring scheduling and triggers, or discussing scenario architecture. Covers WHICH modules to use and WHY — complementary to make-module-configuring which covers HOW to configure each module.
Provides Go patterns for type-first development with custom types, interfaces, functional options, and error handling. Must use when reading or writing Go files.
Create type-safe API endpoints with Encore.ts.
Review code changes against pplx-sdk architecture conventions, type safety, error handling, and testing standards.
Reviews feature specifications for completeness, testability, and implementation readiness. Validates acceptance criteria, edge cases, and technical constraints. Use when reviewing feature specs before implementation or during sprint planning.
Expertise in Go programming decisions according to the Google Go Style Guide. Focuses on specific choices for naming, error handling, and language usage.
