Skill UI

A comprehensive guide to production-grade concurrency patterns in Go. It details the proper use of goroutines, channels, sync primitives, and context management. Use this skill when building highly concurrent applications, implementing worker pools, managing goroutine lifecycles, or debugging race conditions in Go.

This skill provides comprehensive strategies for managing API rate limits, focusing on high-volume and mission-critical workflows. It implements exponential backoff with jitter, task concurrency limiting using `asyncio`, and request queue patterns. Designed to detect and gracefully handle `429 Too Many Requests` errors, ensuring reliable and stable execution even under severe throttling conditions.

This comprehensive skill guides users through the entire debugging lifecycle, from reproducing elusive bugs to tracing the root cause, implementing permanent fixes, and preventing future regressions. It covers advanced techniques like binary search, time travel debugging, and handling common patterns such as race conditions and null values, ensuring professional and systematic troubleshooting for any production issue.

A comprehensive guide and technique set for detecting and exploiting race condition vulnerabilities in web applications. It focuses on bypassing rate limits, exploiting Time-of-Check-to-Time-of-Use (TOCTOU) flaws, and duplicating transactions using advanced methods like Turbo Intruder's single-packet attack. Ideal for security assessments of state-changing operations (e.g., payments, inventory management, coupon redemption).

A comprehensive guide for advanced penetration testing designed to identify flaws in application business rules that automated scanners miss. Focus areas include price manipulation, workflow bypass, privilege escalation, and race conditions. Essential for securing e-commerce platforms, financial systems, and multi-step critical processes.

This technique audits user interaction flows (like button clicks) to detect subtle bugs that static analysis often misses. It specifically tracks the full sequence of state changes, identifying instances where later actions unintentionally cancel, contradict, or leave the UI in an inconsistent state due to state store side effects or race conditions. Ideal for debugging complex state management architectures (Redux, Zustand).

This comprehensive guide covers structured concurrency patterns in Go, focusing on goroutines, channels, mutexes, and various sync primitives. It provides principles for writing, reviewing, and auditing concurrent code to ensure leak-freedom, correct ownership management, and robust error handling, covering topics like context propagation and race condition avoidance.

A comprehensive guide for systematically diagnosing and fixing bugs, crashes, deadlocks, and performance issues in Go code. It covers debugging methodology, utilizing tools like Delve and pprof, detecting race conditions, and following the Golden Rules to find the root cause, ensuring robust and reliable Go development practices.

This CLI alias implements the PUA Loop protocol, designed for running structured, iterative verification cycles. It helps developers set up and manage complex coding tasks that require explicit verification commands and defined stop conditions. It serves as a powerful wrapper for AI coding assistants like Codex/Claude, ensuring robust and traceable development workflows.

A comprehensive methodology for pinpointing the root cause of complex bugs, regressions, or unexpected behavior in large codebases. Techniques include binary search debugging, Git bisect for tracking regressions across commits, strategic data/control flow logging, component isolation, and advanced breakpoint strategies (conditional breakpoints, watch expressions). Ideal for scenarios where the bug source is unclear or difficult to reproduce.

A robust orchestration skill designed for managing large-scale, complex machine learning experiments on remote GPU clusters via SSH. It handles multi-seed sweeps, sequential wave transitions, and deep learning pipelines requiring state management. Features include OOM-aware automatic retries, cleanup of stale terminal sessions, and deterministic scheduling to prevent race conditions, making it ideal for grid computing and staged training.

A collection of production-ready patterns for integrating frontend applications with backend APIs. It solves complex asynchronous issues such as race conditions, stale data, and duplicate requests. Patterns include centralized API layering, request cancellation (AbortController), exponential backoff retries, debouncing, and request deduplication, ensuring highly resilient and reliable user experiences.
