- 01loop-library
Discover, find, compare, audit, repair, adapt, and design repeatable AI-agent loops with explicit triggers, actions, verification, stopping conditions, guardrails, and handoffs. Use when a user asks to analyze a codebase for potential loops, mine coding-thread history for work done more than once, turn repeated engineering work into a loop, find or recommend a published loop, create a recurring agent workflow or automation cadence, turn an outcome into a bounded copy-ready loop, or review an existing loop for weak checks, unsafe authority, unbounded repetition, stale state, or unclear stopping behavior.
Preview SKILL.md - 02boost-asio-pro
Use for any C++ networking code with Boost.Asio or standalone Asio (TCP/UDP, SSL, timers, strands, io_context, co_spawn, awaitable, completion handlers), before writing or reviewing it. Applies lifetime, strand and cancellation rules that avoid the classic async bugs.
