Create FilamentPHP v4 dashboard pages with single-tab or multi-tab layouts, message callouts, and widget integration
Action-oriented architecture for Laravel. Invokable classes that contain domain logic. Use when working with business logic, domain operations, or when user mentions actions, invokable classes, or needs to organize domain logic outside controllers.
PostgreSQL query optimization, JSONB operations, advanced indexing strategies, partitioning, connection management, and database administration. Use this skill for PostgreSQL-specific optimizations, performance tuning, replication setup, and PgBouncer configuration.
OpenAPI documentation skill for Rust APIs using utoipa with Axum framework. Use when building REST APIs with automatic OpenAPI spec generation and Scalar UI. Covers: (1) ToSchema derive for request/response types, (2) #[utoipa::path] for endpoint documentation, (3) OpenApi derive for combining specs, (4) Security schemes (JWT, API keys), (5) IntoParams for query/path params, (6) Scalar UI integration, (7) Response and error handling patterns. Triggers: utoipa, openapi, scalar, axum api, ToSchema, IntoParams, rust api docs.
Research MQL5 documentation (Japanese and English only) for MQL5 creation/editing issues, compile errors, or API questions. Use when users ask to look up docs, interpret MQL5 errors, or confirm correct language usage. Sources limited to https://www.mql5.com/ja/docs and https://www.mql5.com/en/docs.
Wave-based parallel scheduling for DAG execution. Manages execution order, resource allocation, and parallelism constraints. Activate on 'schedule dag', 'execution waves', 'parallel scheduling', 'task queue', 'resource allocation'. NOT for building DAGs (use dag-graph-builder) or actual execution (use dag-parallel-executor).
C# error handling, validation, and Result pattern best practices. Use when handling exceptions, implementing validation, designing error responses, or choosing between exceptions and Result types.
Concurrency with Effect.all, forEach concurrency, Fiber lifecycle, race and timeouts. Use for parallelizing tasks safely.
Guide for debugging and fixing bugs in the OCaml garbage collector, particularly memory management issues in the runtime's sweeping and allocation code. This skill applies when working on OCaml runtime C code, investigating segfaults in GC operations, or fixing pointer arithmetic bugs in memory managers with size-classed pools and run-length encoding.
Guidance for implementing proper asyncio task cancellation with signal handling in Python. This skill applies when implementing concurrent task runners that need graceful shutdown, handling KeyboardInterrupt/SIGINT in asyncio contexts, or managing task cleanup when using semaphores for concurrency limiting. Use when tasks involve asyncio.gather, CancelledError handling, or cleanup of tasks that haven't started execution.
Use when implementing payment processing, Stripe integration, subscription billing, checkout flows, webhooks, or asking about "Stripe", "payments", "subscriptions", "checkout", "PCI compliance", "webhooks", "refunds"
Rust project implementation guide for multi-crate workspace projects. Covers workspace config, toolchain (nightly + rustfmt + clippy + cranky + cargo-deny), strict lint rules (no unsafe/unwrap/expect/panic), error handling (thiserror + anyhow), async runtime (Tokio), TLS (rustls + aws-lc-rs), CI/CD (GitHub Actions with test/build/docker/SBOM), and coding conventions. Use when scaffolding, developing, or reviewing Rust applications.
