Redis observability guidance — which metrics to monitor (memory, connections, hit ratio, ops/sec, rejected connections), which built-in commands to reach for during incident triage (SLOWLOG, INFO, MEMORY DOCTOR, CLIENT LIST, FT.PROFILE), and when to use the Redis Insight GUI. Use when setting up monitoring or alerts for a Redis instance, diagnosing a performance regression, profiling a slow FT.SEARCH query, or wiring Redis metrics into Prometheus, Datadog, or similar.
Redis Query Engine (RQE) guidance covering FT.CREATE schema design, field type selection (TEXT, TAG, NUMERIC, GEO, GEOSHAPE, VECTOR), DIALECT 2 query syntax, efficient FT.SEARCH and FT.AGGREGATE queries, zero-downtime index updates via aliases, and the SKIPINITIALSCAN option. Use when defining a search index on Hash or JSON documents, picking between TEXT and TAG for filtering, writing FT.SEARCH queries with filters and SORTBY, managing or swapping indexes in production, or troubleshooting slow searches with FT.PROFILE.
Writes, reviews, and debugs idiomatic Rust code with memory safety and zero-cost abstractions. Implements ownership patterns, manages lifetimes, designs trait hierarchies, builds async applications with tokio, and structures error handling with Result/Option. Use when building Rust applications, solving ownership or borrowing issues, designing trait-based APIs, implementing async/await concurrency, creating FFI bindings, or optimizing for performance and memory safety. Invoke for Rust, Cargo, ownership, borrowing, lifetimes, async Rust, tokio, zero-cost abstractions, memory safety, systems programming.
ProcessReceipt correctness, prompt APIs, purchase reconciliation, session-lock interaction.
Luau architectural patterns: OOP with metatables, inheritance, async (promises, coroutines, pcall), module structure, service pattern, and Roblox-specific idioms.
Explains how to create and review TypeORM migrations. Use this skill whenever the user wants to change an entity, add or update schema-related database objects, generate a migration, or decide whether a database change should be handled through TypeORM metadata or a custom migration.
REST/GraphQL API design patterns - resource naming, HTTP methods, error handling, pagination, versioning. Use when: design API, REST endpoints, GraphQL schema, error responses, pagination, rate limiting, API documentation.
Asynchronous messaging in Encore.ts via `Topic` and `Subscription` from `encore.dev/pubsub` — broadcast events, decouple producers from consumers, and run background handlers.
Document and verify Doppler's Uniswap V3 liquidity migrator path, used only on v3-only networks when custom fees are required.
Move project setup and configuration on Sui. Use this skill when the user needs to create a Move project, configure Move.toml, resolve dependency or build errors, set up the canonical sui-stack-hello-world project, use MVR dependencies, or migrate from old Move.toml formats. Also use when the user sees errors about "legacy system name", "old dependencies", "Cannot upgrade package without having a published id", edition mismatches, or asks about Move.toml, Published.toml, Move.lock, or the [environments] section.
Use for all CEL and mito work on integrations that collect from APIs — writing CEL programs, cel.yml.hbs templates, manifest configuration, mock-first development with the mito CLI, system test mock setup, and answering CEL/mito questions. Load this skill whenever any data stream uses the cel input type.
Architecture async-first avec messaging et queues (Symfony Messenger, Laravel Queue, Ecotone). Use when working with async processing, queues, workers, background jobs.
