Guide for Phoenix web applications. Use when building Phoenix apps, implementing LiveView, designing contexts, setting up channels, or integrating Tidewave MCP dev tools.
Actix-web framework guardrails, patterns, and best practices for AI-assisted development. Use when working with Actix-web projects, or when the user mentions Actix-web. Provides actor patterns, async handlers, extractors, and high-performance web guidelines.
Route configuration, route model binding, and authorization. Use when working with routes, route binding, URL patterns, or when user mentions routing, route model binding, conditional binding, route-level authorization.
Designs intuitive Python library APIs following principles of simplicity, consistency, and discoverability. Handles API evolution, deprecation, breaking changes, and error handling. Use when designing new library APIs, reviewing existing APIs for improvements, or managing API versioning and deprecations.
Zig cross-compilation skill. Use when cross-compiling Zig programs to different targets, using Zig's built-in cross-compilation for embedded, WASM, Windows, ARM, or using zig cc to cross-compile C code without a system cross-toolchain. Activates on queries about Zig cross-compilation, zig target triples, zig cc cross-compile, Zig embedded targets, or Zig WASM.
Profile-guided optimisation skill for C/C++ with GCC and Clang. Use when squeezing maximum runtime performance after standard optimisation plateaus, implementing two-stage PGO builds, collecting profile data, or applying BOLT for post-link optimisation. Activates on queries about PGO, profile-guided optimization, fprofile-generate, fprofile-use, instrumented builds, or BOLT.
C++ and Rust memory model skill for concurrent programming. Use when understanding memory ordering, writing lock-free data structures, using std::atomic or Rust atomics, diagnosing data races, or selecting the correct memory order for atomic operations. Activates on queries about memory ordering, acquire-release, seq_cst, relaxed atomics, happens-before, memory barriers, std::atomic, or Rust atomic ordering.
Rust profiling skill for performance analysis. Use when generating flamegraphs from Rust binaries, measuring monomorphization bloat with cargo-llvm-lines, analysing binary size with cargo-bloat, microbenchmarking with Criterion, or interpreting inlined frames in profiles. Activates on queries about cargo flamegraph, cargo-bloat, cargo-llvm-lines, Criterion benchmarks, Rust performance profiling, or binary size analysis.
Senior Java & Spring Boot 4 / Spring Framework 7 architect skill for 2026-standard development. Use when the user asks to build, scaffold, design, review, or explain Java applications using Spring Boot 4.x, Spring Framework 7.x, Spring Modulith, or any related Spring ecosystem project. Triggers include: creating REST APIs, designing microservices, configuring data access (JdbcClient, JPA 3.2, R2DBC), reactive programming (WebFlux), security (Spring Security 7), observability, GraalVM native images, Gradle/Maven build configuration, Jakarta EE 11 migration, and any task requiring idiomatic modern Java (Java 25: records, sealed classes, structured concurrency, scoped values, pattern matching, JSpecify null safety).
REST and GraphQL API design patterns. Covers HTTP methods, status codes, versioning, pagination, error handling, schema design, mutations, and API best practices. Trigger: When designing APIs, when creating REST endpoints, when implementing GraphQL schemas, when handling API versioning, when designing pagination.
Database schema migrations and change management. Covers Prisma migrations, schema versioning, rollback strategies, and safe production deployments. Trigger: When creating database migrations, when modifying schemas, when deploying database changes, when handling rollbacks.
Use when implementing production-quality bioinformatics software with proper error handling, logging, testing, and documentation, following software engineering best practices.
