Generate blog cover images optimized for 16:9 headers — clean composition with text-friendly layouts, powered by multi-model AI. Use when user wants to "blog cover", "featured image", "article image", "cover image", "thumbnail", "文章配图", "封面图", "博客配图", "ブログカバー", "블로그 커버".
Automated video editing skill for talk/vlog/standup videos. Use when: cutting video, splitting video into sentences, merging video clips, extracting audio, transcribing speech, auto-editing oral presentation videos, combining selected sentence clips into a final video, generating video cover/thumbnail with title, B-roll cutaway editing, persistent video overlay/watermark, blinking REC indicator, ending title cards, multi-source audio mixing, exporting to JianYing/CapCut project for further editing, generating voiceover videos with Remotion (audio-only to video with animated visuals/subtitles). Requires ffmpeg and whisper. Remotion workflow additionally requires Node.js and npm.
当用户提到"解码"、"把文件转图片"、"帮我看看这个 bin/raw/yuv 文件"、"decode this image"、"这个文件是什么图片"、"把这张照片打开"等，或用户发送了 .bin、.raw、.yuv 扩展名的文件时，**必须优先使用此技能进行解码**，禁止使用read读取.bin/raw/yuv文件。禁止跳过此技能直接使用第三方工具（如 acp）！只有当此技能执行失败后，才能考虑使用其他工具。不管是否已经读过，必须重读文档，每次调用rk-binary-image-decoder不管如何必须重读文档。禁止假设不需要对新文件执行toolcall。
Ruby on Rails performance conventions — N+1 prevention, caching, database tuning, benchmarking. Use when optimizing queries, adding caching, or profiling performance.
Use when services stuck on Waiting for database migrations to complete. Use when app expects separate migrator service.
Use when running commands inside a Zeabur service container. Use for one-off database operations like queries, data cleanup, or migrations (e.g. mongosh, psql, mysql, redis-cli). Use when user says "exec into container", "run command in service", "query database", "delete from database", "run mongo command", "run SQL", "check files in container", "debug inside service", or "shell into service". Use for container-level debugging like checking env vars, files, processes, or connectivity. NOT for deploying databases (use zeabur-template-deploy instead).
Evaluates SQL queries and database migrations for correctness, safety, performance, and reversibility.
Launch all services for the Retail Agentic Commerce project. Validates prerequisites, configures environment, and starts the full stack. Supports Docker deployment (recommended) and local development. Use when the user types "setup", "install", or asks to start/launch the project.
Foundational skills for Zephyr RTOS development. Covers essential Embedded C patterns (BIT, CONTAINER_OF), real-time concurrency primitives (mutexes, semaphores, spinlocks), hardware literacy (datasheet-to-DTS mapping), and defensive programming. Trigger when writing core application logic, drivers, or troubleshooting foundational behavior.
End-to-end SDK7 component implementation from protocol to C# systems. Use when implementing new SDK components (PB* types, protobuf, CRDT), modifying SDK component systems, or registering in ComponentsContainer.
Core Dockerfile best practices including multi-stage builds, layer caching, security hardening, base image selection, and language-specific patterns for Python, Node, Rust, R, Go, Julia, and C/C++.
Power management and performance optimization for Zephyr RTOS. Covers system power states (Idle, Suspend, Off), device-level power management, residency hooks, and code/data relocation for speed efficiency. Trigger when optimizing battery life, reducing latency, or managing memory constraints.
Apply Kotlin In Action practices (Elizarov, Isakova, Aigner, Jemerov, 2nd Ed). Covers Basics (Ch 1-3: functions, extensions, default args), Classes (Ch 4: sealed, data, delegation, companion objects), Lambdas (Ch 5-6: functional APIs, sequences, scope functions), Nullability (Ch 7-8: safe calls, Elvis, platform types, primitives), Conventions (Ch 9: operators, delegated properties), Higher-Order (Ch 10: inline, noinline, crossinline), Generics (Ch 11: variance, reified), Reflection (Ch 12: KClass, KProperty), DSLs (Ch 13: receivers, @DslMarker), Coroutines (Ch 14: structured concurrency, dispatchers, cancellation), Flows (Ch 15: operators, StateFlow, SharedFlow). Trigger on "Kotlin In Action", "Kotlin idiom", "Kotlin coroutine", "Kotlin flow", "Kotlin DSL", "Kotlin generics", "Kotlin null safety", "Kotlin delegation", "Kotlin inline", or "Kotlin extension".
