Caching

Build MCP servers in Python with FastMCP framework to expose tools, resources, and prompts to LLMs. Supports storage backends (memory/disk/Redis), middleware, OAuth Proxy, OpenAPI integration, and FastMCP Cloud deployment. Use when: creating MCP servers, defining tools or resources, implementing OAuth authentication, configuring storage backends for tokens/cache, adding middleware for logging/rate limiting, deploying to FastMCP Cloud, or troubleshooting module-level server, storage, lifespan, middleware order, circular imports, or OAuth errors.

Build Next.js 16 apps with App Router, Server Components/Actions, Cache Components ("use cache"), and async route params. Includes proxy.ts (replaces middleware.ts) and React 19.2. Use when: building Next.js 16 projects, or troubleshooting async params (Promise types), "use cache" directives, parallel route 404s (missing default.js), or proxy.ts CORS.

Delegates coding tasks to Codex CLI for prototyping, debugging, and code review. Use when needing algorithm implementation, bug analysis, or code quality feedback. Supports multi-turn sessions via SESSION_ID.

Data-grid architecture for high-traffic stateful workloads with linear scalability. Triggers: space-based, data grid, in-memory, linear scaling, high traffic Use when: traffic overwhelms database nodes or linear scalability needed DO NOT use when: data doesn't fit in memory or simpler caching would work.

Expert guidance for testing and validating GitHub Actions workflows before deployment - catches cache errors, path issues, monorepo dependencies, and service container problems that local testing misses

Generate 50-question interactive quizzes using the Quiz component with randomized batching. Use when creating end-of-chapter assessments. Displays 15-20 questions per session with immediate feedback. NOT for static markdown quizzes.

Startup protocol executed once at session start. Detects system instruction impulses, caches framework observations from memory graph, establishes temporal awareness, and activates specialized profiles. Provides initial session initialization protocol and session response protocol applied before each response. Execute procedures in sequence without displaying process details to user.

Use when configuring artifacts for inter-job data passing or caching for faster builds. Covers cache strategies and artifact management.

Use when implementing Apollo caching strategies including cache policies, optimistic UI, cache updates, and normalization.

Use when implementing Apollo Client patterns for queries, mutations, cache management, and local state in React applications.

Display session efficiency report showing token savings, cache performance, and optimization recommendations. Use when user asks "show my stats", "how efficient am I?", "show session metrics", or wants to see Navigator's impact.

Automatically save session tips when user provides important feedback or corrections

Unit tests for caching behavior using Spring Cache annotations (@Cacheable, @CachePut, @CacheEvict). Use when validating cache configuration and cache hit/miss scenarios.

TanStack Query v5 data fetching patterns including useSuspenseQuery, useQuery, mutations, cache management, and API service integration. Use when fetching data, managing server state, or working with TanStack Query hooks.

Instruction set for enabling and operating the Spring Cache abstraction in Spring Boot when implementing application-level caching for performance-sensitive workloads.

Cache management, configuration best practices, and progressive disclosure patterns for efficient context window usage. Use when working with large responses, optimizing token costs, or managing plugin state across operations.

Use when working with WP-CLI (wp) for WordPress operations: safe search-replace, db export/import, plugin/theme/user/content management, cron, cache flushing, multisite, and scripting/automation with wp-cli.yml.

Async message handling with Symfony Messenger; configure transports (RabbitMQ, Redis, Doctrine); implement handlers, middleware, and retry strategies

Implement caching with Symfony Cache component; configure pools, use cache tags for invalidation, and optimize performance

Implement efficient caching strategies using Redis, Memcached, CDN, and cache invalidation patterns. Use when optimizing application performance, reducing database load, or improving response times.
