WebAssembly runtime skill using wasmtime. Use when running WASM modules with wasmtime CLI, working with WASI preview2, using the component model, embedding wasmtime in Rust applications, limiting execution with fuel metering, or debugging WASM with DWARF in wasmtime. Activates on queries about wasmtime, WASI, WASM component model, wasmtime embedding, WIT interfaces, fuel metering, or server-side WebAssembly.
Embedded Rust skill for bare-metal microcontroller development. Use when using probe-rs or cargo-embed for flashing and debugging, setting up defmt logging, using the RTIC framework, configuring cortex-m-rt startup, writing no_std + no_main firmware, or choosing between panic-halt and panic-semihosting. Activates on queries about embedded Rust, probe-rs, cargo-embed, defmt, RTIC, cortex-m-rt, no_std embedded, or panic handling in embedded Rust.
Core dump analysis skill for production crash triage. Use when loading core files in GDB or LLDB, enabling core dump generation on Linux/macOS, mapping symbols with debuginfo or debuginfod, or extracting backtraces from crashes without re-running the program. Activates on queries about core files, ulimit, coredumpctl, debuginfod, crash triage, or analyzing segfaults from production binaries.
Concurrency debugging skill for diagnosing data races and deadlocks. Use when reading TSan race reports, debugging deadlocks with GDB thread inspection, analyzing lock-order graphs with Helgrind, identifying std::atomic misuse patterns, or reasoning about happens-before in C++ and Rust. Activates on queries about data races, TSan reports, deadlocks, Helgrind, lock ordering, thread sanitizer output, or atomic ordering issues.
Manage account balance, payments, invoices, webhooks, and view audit logs and detail records. This skill provides JavaScript SDK examples.
Use when you need to add or review Flyway database migrations in a Spring Boot application — Maven dependencies, db/migration scripts, spring.flyway.* configuration, baseline and validation, and alignment with JDBC or Spring Data JDBC. Part of the skills-for-java project
Implements RESTful API design with versioning and request specs. Use when building APIs, adding API endpoints, versioning APIs, or when user mentions REST, JSON API, or API design. WHEN NOT: Internal-only endpoints, HTML views, Turbo Stream responses, or APIs without external consumers.
Write, scaffold, explain, and debug plugins for the Pelican gaming panel. Use this skill whenever the user mentions Pelican plugins, extending Pelican, FilamentPHP resources or pages for Pelican, plugin service providers, custom permissions, plugin settings, routes, models, widgets, or asks how to add new functionality to the Pelican panel.
Use when writing server-side TypeScript code involving domain models, use cases, repositories, state transitions, or business logic. Guides functional domain modeling with discriminated unions, pure functions, and Result types.
Registers state-type triggers that automatically fire functions when key-value state is created, updated, or deleted within a scope. Use when building reactive side effects, change watchers, audit logs, cache invalidation, notification dispatchers, or any observer pattern where data changes should trigger downstream processing.
Architecture standard for building robust, type-safe TypeScript services using the "Spec and Handler" pattern. Use when building CLIs, libraries, or complex business logic.
12-Factor App patterns for deployable applications. Use when configuring environment variables, connecting to backing services, structuring application startup/shutdown, or handling graceful shutdown and process signals. Applies to any deployed application (services, APIs, frontends, workers). Server-specific factors (port binding, concurrency, disposability) apply only to backend services.
