Cache expensive file processing results using SHA-256 content hashes instead of file paths. \n \n Content-hash keys survive file moves and auto-invalidate when content changes, eliminating path-based cache brittleness \n Store cache entries as individual {hash}.json files for O(1) lookup without requiring a separate index \n Implement caching as a service layer wrapper around pure processing functions, keeping extraction logic separate from cache concerns \n Handle cache corruption gracefully by

Comprehensive C#/.NET design pattern analysis with actionable improvement recommendations. \n \n Evaluates six core patterns: Command, Factory, Dependency Injection, Repository, Provider, and Resource patterns against GoF and SOLID principles \n Analyzes architecture compliance including namespace conventions, project separation, async/await patterns, and structured logging implementation \n Reviews code quality across security, testability, maintainability, and performance dimensions with speci

This pattern handles a common Next.js requirement: client-side interaction (button click) that needs to set server-side cookies.

Implement circuit breaker patterns to prevent cascading failures and provide graceful degradation when dependencies fail.

Distributed transaction management across microservices using choreography or orchestration patterns. \n \n Supports two saga approaches: choreography-based (event-driven, decoupled) and orchestration-based (centralized coordinator with easier tracking) \n Requires compensating transactions for every forward operation to ensure rollback capability and eventual consistency \n Integrates with Spring Boot 3.x, Kafka, RabbitMQ, and frameworks like Axon Framework, Eventuate Tram, and Camunda \n Empha

Identify and resolve common Rust code anti-patterns during review. \n \n Covers eight major anti-patterns with explanations and idiomatic alternatives, including excessive cloning, unwrap in production, and fighting the borrow checker \n Provides a thinking framework to distinguish symptoms from root causes and trace issues to underlying design problems \n Includes quick reference tables for beginner mistakes, code smells, common error patterns, and deprecated approaches with fixes \n Links anti
