Refactoring and tidying OCaml code to be more idiomatic. Use when the user asks to tidy, clean up, refactor, or improve OCaml code, or when reviewing Claude-generated OCaml code for consolidation.

ClickHouse schema design authority (hub skill). Use when designing schemas, selecting compression codecs, tuning ORDER BY, optimizing queries, or reviewing table structure. **Delegates to**: clickhouse-cloud-management for user creation, clickhouse-pydantic-config for DBeaver config, schema-e2e-validation for YAML contracts. Triggers: "design ClickHouse schema", "compression codecs", "MergeTree optimization", "ORDER BY tuning", "partition key", "ClickHouse performance", "SharedMergeTree", "ReplicatedMergeTree", "migrate to ClickHouse".

Publishing OCaml to npm via js_of_ocaml and wasm_of_ocaml. Use when discussing browser targets, JavaScript compilation, WASM output, npm packages, or the two-branch workflow.

This skill creates a complete MkDocs Material project structure for intelligent textbooks. It sets up a Conda virtual environment named 'mkdocs', installs all dependencies, generates mkdocs.yml with all Material theme options, custom CSS for branding, the social_override plugin for custom social media cards, builds the site, and deploys to GitHub Pages. Use this skill when starting a new intelligent textbook project.

Web scraping toolkit using MCP scraper tools. Invoked when extracting content from web pages, converting HTML to markdown, extracting plain text, or harvesting links from URLs. Provides four specialized tools for different extraction needs with CSS selector filtering, batch operations, and retry logic.

Runs performance benchmarks for SDL3 HammerEngine and detects regressions by comparing metrics against baseline. Use when testing performance-sensitive changes to AI, collision, pathfinding, particle systems, or before merging features to ensure no performance degradation.

When reading or writing pyproject.toml or .toml config files in Python. When editing TOML while preserving comments and formatting. When designing configuration file format for a Python tool. When code uses tomlkit or tomllib. When implementing atomic config file updates.

This skill generates interactive maps using the Leaflet JavaScript library. Use this skill when users need to create geographic visualizations, location-based data displays, or interactive maps for educational textbooks. The skill creates complete MicroSim packages with HTML, CSS, and documentation, optimized for iframe embedding in narrow MkDocs pages with navbar and TOC.

Meta-skill for creating Claude Code skills. TRIGGERS - create skill, YAML frontmatter, validate skill, TodoWrite templates, bundled resources (scripts/references/assets), progressive disclosure, allowed-tools, skill architecture. Use when creating, validating, or structuring skills.

Use when making UI/styling changes and need to verify no visual regressions - provides screenshot capture, comparison, vision model scoring, and video recording for animations

Create an educational MicroSim using the vis-network JavaScript library. Each MicroSim is a directory located in the /docs/sims folder. It has a main.html file that can be referenced with an iframe. The main.html file imports the main JavaScript code to run the educational MicroSim.

Run Earthly E2E validation for YAML schema contracts. Use when validating YAML schema changes, testing schema contracts against live ClickHouse, or regenerating Python types, DDL, and docs from YAML. For SQL schema design and optimization, use clickhouse-architect skill instead.

Critical Phoenix HTML and HEEx template guidelines that prevent common bugs and syntax errors. Use when writing Phoenix templates, HEEx files, LiveView templates, or any code using `~H` sigils. Prevents common mistakes with form handling, conditional syntax, class attributes, interpolation, and template comments that cause compilation errors or runtime bugs.

Create an interactive classification quiz MicroSim using p5.js where students read scenarios and classify them into the correct category from multiple choice options. Uses a data.json file for easy question editing. Ideal for teaching students to recognize patterns, identify types, or categorize examples across any subject domain.

Working with IETF RFCs in OCaml projects. Use when mentioning RFC numbers, implementing internet standards, adding specification documentation, or discussing protocol compliance.

Creating OCaml library tutorials using .mld documentation format with MDX executable examples. Use when discussing tutorials, documentation, .mld files, MDX, or interactive documentation.

Semantic analysis for Claude Code consumption. TRIGGERS - analyze cast, keyword extraction, density analysis, find patterns, sharpe, backtest, iteration, trading keywords, ML keywords. Use when extracting insights from recordings.

Router skill directing to deployment, optimization, MLOps, and monitoring guides.
