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.
Launch and automate VS Code (Code OSS) using agent-browser via Chrome DevTools Protocol. Use when you need to interact with the VS Code UI, automate the chat panel, test UI features, or take screenshots of VS Code. Triggers include 'automate VS Code', 'interact with chat', 'test the UI', 'take a screenshot', 'launch Code OSS with debugging'.
Comprehensive guide for developing in the Astro monorepo. Covers architecture, debugging, testing, and critical constraints. Use when working on features, fixes, tests, or understanding the codebase structure.
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.
Go error handling patterns: wrapping with context, sentinel errors, custom error types, errors.Is/As chains, and HTTP error mapping. Use when implementing error returns, defining package-level errors, creating custom error types, wrapping errors with fmt.Errorf, or checking errors with errors.Is/As. Use for "error handling", "fmt.Errorf", "errors.Is", "errors.As", "sentinel error", "custom error", or "%w". Do NOT use for general Go development, debugging runtime panics, or logging strategy.
C and C++ compiler toolchain skill covering GCC, Clang/LLVM, build modes, warnings, sanitizers, static analysis, LTO, PGO, C++20/23/26 features, and debugging. Use when writing or reviewing C/C++ code, choosing compiler flags, interpreting errors or warnings, enabling sanitizers, running clang-tidy or cppcheck, optimizing builds, working with C++20 modules or C23 features, or troubleshooting linker issues.
Grafana Alerting, Incident Response Management (IRM), and SLOs. Covers Grafana-managed and data source-managed alert rules, notification policies, contact points (Slack/PagerDuty/email/webhook), silences, muting, on-call scheduling, incident management workflows, and SLO configuration with burn-rate alerts. Use when configuring alerts, debugging notification routing, setting up on-call rotations, managing incidents, defining SLOs, or provisioning alerting via YAML/API.
Stage 1 spec compliance review. Triggers: /review stage 1. Verifies implementation matches design specification — functional completeness, TDD compliance, and test coverage. Do NOT use for code quality checks — use quality-review instead. Do NOT use for debugging.
Integrates Superwall paywalls and subscription gating in React Native Expo apps using the expo-superwall SDK. Use when adding Superwall to an Expo (SDK 53+) project, wiring placements/feature gating, managing users and subscription status, handling deep links/web checkout, integrating RevenueCat, or debugging native-module issues.
Manages Starwind UI components and Astro projects - initializing, adding, searching, fixing, debugging, styling, theming, and composing UI. Provides project context, component docs, CLI guidance, and Starwind-specific composition rules. Applies when working with Starwind UI, Starwind components, Astro + Tailwind CSS v4 UI, starwind.config.json, theme tokens, dark mode, shadcn-style theme migration, or component requests such as Combobox mapping to Select.
Interacts with Google Cloud services using the gcloud CLI safely and efficiently. Covers command validation, data reduction, safety guardrails with a denylist, and workflows for discovery and investigation. You MUST read this skill before invoking any gcloud command. Use when managing cloud resources, querying configurations, or troubleshooting issues via gcloud. Don't use when writing or debugging Google Cloud client library code or raw REST/gRPC API interactions.
Patterns and anti-patterns for using OpenAI Codex Goals — the persistent objectives feature introduced in Codex 0.128.0. Use this skill whenever writing, reviewing, or debugging a `/goal` invocation, deciding whether a task should be a Goal at all, drafting a research Goal that needs an evidence ledger, or diagnosing a Goal that completed against the wrong surface. Triggers on `/goal`, "Codex Goal", "Codex goals", "persistent objective", "evidence-based completion", "iteration policy", "blocked stop condition", or any user message describing a multi-turn Codex task with a defined finish line. Trigger even if the user doesn't explicitly mention Goals — if they're typing "/goal" or asking Codex to "keep going until X", this skill applies.
