Guide REST API integration including HTTP methods, authentication, error handling, and rate limiting. Use this skill when the user needs to connect to a third-party API, design an API client, troubleshoot API errors, or understand API concepts — even if they say 'connect to this API', 'why is the API returning errors', 'how do I authenticate', or 'build an API integration'.
C++20 coroutines skill for understanding coroutine mechanics and debugging. Use when working with co_await, co_yield, co_return, implementing promise_type, understanding coroutine frame layout, debugging suspended coroutines in GDB, or inspecting frame allocation with Compiler Explorer. Activates on queries about C++20 coroutines, co_await, co_yield, promise_type, coroutine_handle, coroutine suspension, or coroutine frame.
Zephyr RTOS skill for embedded development. Use when building Zephyr applications with west, configuring boards and targets, working with Kconfig and devicetree, using the Zephyr shell and logging subsystem, or running on the native_sim target. Activates on queries about Zephyr, west build, Kconfig, devicetree, Zephyr logging, west flash, board targets, or native POSIX simulation.
GDB debugger skill for C/C++ programs. Use when starting a GDB session, setting breakpoints, stepping through code, inspecting variables, debugging crashes, using reverse debugging (record/replay), remote debugging with gdbserver, or loading core dumps. Activates on queries about GDB commands, segfaults, hangs, watchpoints, conditional breakpoints, pretty-printers, Python GDB scripting, or multi-threaded debugging.
[Pragmatic DDD Architecture] Guide for Authentication configuration and the `auth` Bounded Context. Use when modifying auth flows, adding social providers, configuring email templates/Resend, working with the Better Auth client/server configurations, or modifying `src/auth/` components and components dependent on session handling.
How to benchmark and analyze memory usage in Turso using the memory-benchmark crate and dhat heap profiler. Use this skill whenever the user mentions memory usage, memory profiling, allocation tracking, heap analysis, memory regression, memory benchmarking, dhat, or wants to understand where memory is being allocated during SQL workloads. Also use when investigating memory growth in WAL or MVCC mode. IMPORTANT - If you modify the perf/memory crate (add profiles, change CLI flags, change output format, etc.), update this skill document to reflect those changes so it stays accurate for future agents.
