Explain blockchain fundamentals including distributed ledger architecture, consensus mechanisms, and block structure. Use this skill when the user needs to understand blockchain concepts, evaluate whether blockchain fits a use case, or design a blockchain-based solution — even if they say 'how does blockchain work', 'do I need blockchain', or 'distributed ledger'.
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.
Linux kernel module skill for writing and debugging loadable kernel modules. Use when writing LKMs with Kbuild, adding module parameters, creating /proc and sysfs entries, implementing character devices, debugging with KGDB or ftrace, or handling module signing for Secure Boot. Activates on queries about Linux kernel modules, loadable modules, Kbuild, module parameters, /proc filesystem, sysfs, character devices, KGDB, or module signing.
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.
Query and manage databases (SQLite, PostgreSQL, MySQL). Execute queries, explore schemas, and manage data.
Port phone numbers into Telnyx. Check portability, create port orders, upload LOA documents, and track porting status. This skill provides JavaScript SDK examples.
SuiteScript records and fields reference. Look up field IDs, types, required status, and search capabilities for all 272 NetSuite record types. Use this when building SuiteScript to ensure correct field usage.
Build, debug, and extend integrations with the EasyPost shipping API. Use this skill whenever the user mentions EasyPost, shipping labels, postage, rate shopping, tracking packages programmatically, customs forms, carrier accounts (USPS/UPS/FedEx/DHL/ePost Global), scan forms, pickups, shipping insurance, or webhooks for shipping events. Also trigger on phrases like "create a shipping label," "buy postage," "rate a parcel," "verify an address," "international shipment," "commercial invoice," "Luma rate shopping," "UPS DAP," "DHL eCommerce," or any task involving the `@easypost/api` Node.js SDK or REST endpoints under `api.easypost.com/v2`. Optimized for Node.js/TypeScript but the REST patterns, field names, and carrier gotchas apply in any language.
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.
Prevent N+1 queries by eager loading; enable lazy-loading protection in non-production; choose selective fields
Creates scoped key-value stores, reads and writes state entries, lists keys, and performs partial updates across functions. Use when persisting data between invocations, managing user sessions, caching computed values, storing feature flags, sharing state between workers, or building a KV data layer as an alternative to Redis or DynamoDB.
Exposes iii functions as REST API endpoints. Use when building HTTP APIs, webhooks, or inbound request handling where iii owns the route.
