Skills

Records decisions and documentation. Use when making architectural decisions, changing public APIs, shipping features, or recording context.

Create interactive canvas-based designs and visualizations. Use when users need HTML5 Canvas applications, interactive graphics, data visualizations, or creative coding projects.

Open or create a design document. Use when you need to initialize design tasks, create new files, or switch to specific designs.

Read design variables Tokens . Use to get Design Tokens color font variables defined in the current document to ensure consistency.

Guidance for debugging and troubleshooting Docker issues. Covers container startup failures (exit codes, docker logs, inspect), disk space exhaustion (system df/prune, log rotation), OOM and resource pressure (memory limits, stats), network connectivity problems (network inspect, iptables, DNS resolution), storage issues (permission denied, volume inspection), daemon problems (dockerd startup, socket permissions), and common error diagnosis. Use when the user asks about docker troubleshooting, docker debug, OOM, disk full, network issues, docker not starting, container crash, or needs to investigate Docker problems. 使用场景：docker 排查、docker debug、容器问题、OOM、磁盘满、网络不通、启动失败、配置问题.

Explore design style tags. Use to get design inspiration, such as 'Modern', 'Dark Mode', 'SaaS' directions.

Get specific style detailed definitions. Use to get metadata for a specific style, including palettes, typography rules, etc.

Guidance for Testcontainers — running Docker containers in automated integration tests. Covers Java (@Testcontainers, @Container, PostgreSQL/Redis/Kafka/Elasticsearch), Python (testcontainers-python with pytest), container lifecycle management (singleton, reuse), CI/CD integration (Docker-in-Docker, Ryuk), Testcontainer best practices, and database migration testing. Use when the user asks about testcontainers, integration testing with Docker, database testing, Java testcontainers, Python testcontainers, or needs to test with real Docker services. 使用场景：testcontainers、集成测试、docker 测试、数据库测试、Java Testcontainers、Python Testcontainers.

Autonomous iteration loop: modify, verify, keep/discard against any metric

Get node visual screenshot. Visual Verification. Use to capture screenshots after operations to verify if the design meets expectations.

Get design system guidelines. Use to read and understand specifications e.g. Material Design iOS HIG or custom specs before designing.
