Container Best Practices
by markus41
Expert guidance on dockerfile optimization, multi-stage builds, layer caching strategies, and base image selection. Activates when working with "dockerfile", "docker-compose", "multi-stage", "container optimization", "image layers", or "build cache".
FastAPI Background Tasks
by markus41
This skill should be used when the user asks to "create background task", "add async job", "implement task queue", "schedule periodic task", "use Celery", "use ARQ", "process async", or mentions background processing, task queues, job scheduling, workers, or async jobs. Provides multiple task queue framework patterns.
geju
by hylarucoder
Produces a bold, high-altitude direction judgment (格局判断): a sharp thesis on the right target model, a kill-list of what to delete / merge / split / reframe, a Conservative-vs-Clean-vs-Staged options table, and a verification path (first proof point + falsifier) that keeps the bold call testable. Use whenever the user wants to think bigger, open the design space, or challenge a conservative / incremental / over-compatible proposal — proactively, even when unnamed. Triggers: 打开格局, 格局太小, 你格局小了, 拔高一点, 站高一点, 别太保守, 太碎了, 别老想着兼容, 别被重构难度绑架, 大方向; and English "too incremental / too safe", "play it bigger", "greenfield this", "what if there were no legacy". Once the bold direction needs feasibility / landing pressure-testing, route to goudi.
hai-naming
by hylarucoder
Produces 3-5 candidate names with one recommended final name, the three-stage reasoning trail behind it (research-stage / top-of-head / final-after-reading), and — for reviews — a priority-ordered rename list with old->new and migration scope. Use when the user asks how to name or rename anything (concept, variable, function, module, type, file, product surface, domain entity, event, workflow state, or abstraction), wants a naming review or audit, or says a name feels vague, stiff, misleading, inconsistent, too long, too generic, or hard to choose — even if they only mention it in passing while reviewing code. Be pushy: trigger on "what should I call this", "better name for X", "this name sucks", "rename this var", "whats a good name", "review my naming", and when every candidate feels awkward (usually a design- boundary problem, not a vocabulary one). Chinese triggers: 起名, 命名, 取名, 改名, 名字不好, 这个叫什么好, 取个名字, 换个名, 这名字怎么样, 名字太长, 命名规范, 命名审查, 变量名/函数名怎么取.
