Structured code review for security, performance, correctness, and maintainability across PR diffs and file changes. Audits security risks including SQL injection, XSS, CSRF, authentication flaws, and credential exposure Identifies performance issues like N+1 queries, memory leaks, algorithmic complexity, and resource leaks Checks correctness for edge cases, race conditions, error handling, and type safety gaps Works standalone with diffs and file paths; integrates with source control,...

by samber

Golang performance optimization patterns and methodology - if X bottleneck, then apply Y. Covers allocation reduction, CPU efficiency, memory layout, GC tuning, pooling, caching, and hot-path optimization. Use when profiling or benchmarks have identified a bottleneck and you need the right optimization pattern to fix it. Also use when performing performance code review to suggest improvements or benchmarks that could help identify quick performance gains. Not for measurement methodology (→...

In-memory caching in Golang using samber/hot — eviction algorithms (LRU, LFU, TinyLFU, W-TinyLFU, S3FIFO, ARC, TwoQueue, SIEVE, FIFO), TTL, cache loaders, sharding, stale-while-revalidate, missing key caching, and Prometheus metrics. Apply when using or adopting samber/hot, when the codebase imports github.com/samber/hot, or when the project repeatedly loads the same medium-to-low cardinality resources at high frequency and needs to reduce latency or backend pressure.

Durable graph execution with thread-scoped checkpoints, state history, and cross-thread long-term memory. Three checkpointer options: InMemorySaver for testing, SqliteSaver for local development, PostgresSaver for production; always pass thread_id in config to enable persistence Browse and replay from past checkpoints using get_state_history() , fork execution by updating state at a past point, or manually modify state before resuming Store API provides cross-thread memory for user...

Apollo iOS is a strongly-typed GraphQL client for Apple platforms. It generates Swift types from your GraphQL operations and schema, and ships an async/await client, a normalized cache (in-memory or SQLite-backed), a pluggable interceptor-based HTTP transport that handles queries, mutations, and multipart subscriptions, and an optional WebSocket transport ( graphql-transport-ws ) that can carry any operation type.
