Skill UI

This skill monitors for regressions on deployed URLs following deployments, merges, or dependency upgrades. It performs comprehensive checks including HTTP status, console errors, network failures, performance metrics (LCP/CLS/INP), and crucial API endpoint health, ensuring service stability in production or staging environments. Supports quick checks, continuous monitoring, and differential comparison against baselines.

Guides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Covers REST/GraphQL endpoints, type contracts, error semantics, validation, and extensibility principles.

Forces a terse caveman-style voice in every reply: answer first, ceremony and filler removed, while all technical facts, code, paths, numbers and errors stay verbatim. Activate with /caveman or "be brief" to cut token cost without losing accuracy.

Guides systematic root-cause debugging when tests fail, builds break, or behavior unexpectedly changes. It covers stop-the-line discipline, a triage checklist, git bisection for regressions, minimal reproduction, root-cause fixes, regression tests, and end-to-end verification. Ideal for turning confusing errors into reliable recovery workflows.

Guides configuring Firebase AI in Flutter, generating text/chat with Gemini, streaming responses, multimodal prompts, and handling errors with security considerations.

Comprehensive guide for implementing Firebase Authentication in Flutter apps. Covers setup, auth state management, email/password sign-in, social login, error handling, and security best practices for production-ready auth flows.

Skill for implementing Firebase Crashlytics in Flutter apps. Covers fatal/non-fatal error capture, async and isolate exceptions, crash customization with keys/logs/user IDs, symbol upload, opt-in data collection, and debug build disables.

Use this skill to correctly set up Firebase Data Connect in Flutter apps. Covers schema and connector design, typed SDK generation, executing queries and mutations, real-time listeners, pagination, offline handling, error recovery, and security rules.

A practical guide for using Firebase Cloud Storage in Flutter apps. Covers setup, file upload/download, metadata management, error handling, progress monitoring, and security rules.

Provides solutions for common Flutter runtime and layout errors, including RenderFlex overflow, unbounded constraints, unbounded width, setState during build, ScrollController conflicts, and RenderBox layout issues. Includes debugging tips and constraint fixes for developers.

This skill provides comprehensive guidelines for structured concurrency in Go. It covers best practices for managing goroutine lifecycles, preventing leaks, and choosing between channels, mutexes, and atomic operations. It details patterns like fan-out/fan-in, error handling with `errgroup`, and deduplication with `singleflight`, ensuring correct and leak-free concurrent code.

This skill provides comprehensive guidance on idiomatic Go patterns for building production-ready, robust applications. It covers best practices like functional options, proper constructor design, resource management (timeouts, graceful shutdown), error handling, concurrency patterns, and architectural styles (DDD, Hexagonal). Use it when structuring complex Go APIs, defining service boundaries, or auditing existing code for common anti-patterns and performance pitfalls.
