Comprehensive Solidity smart contract development skill using Foundry framework. Use for writing, testing, deploying, and auditing Solidity contracts with security-first practices. Also triggers when working with .sol files, Foundry project files (foundry.toml), test files (.t.sol), or smart contract deployment scripts. Example triggers: "Write smart contract", "Create Solidity test", "Deploy contract", "Audit smart contract", "Fix security vulnerability", "Write Foundry test", "Set up Foundry project"

Plan ML projects using CRISP-DM, TDSP, and MLOps methodologies with proper phase gates and deliverables.

dbt with TD Trino. Covers profiles.yml setup (method:none, user:TD_API_KEY), required override macros (no CREATE VIEW), TD_INTERVAL in models, and TD Workflow deployment.

Assess agentic layer maturity using the 12-grade classification system (Class 1-3). Use when evaluating codebase readiness, identifying next upgrade steps, or tracking progress toward the Codebase Singularity.

Define data ownership, stewardship roles, data classification, retention policies, and access control frameworks.

Manages CDP child segments using `tdx sg` commands with YAML rule configs. Covers filtering with operators (Equal, In, Greater, TimeWithinPast, Contain), folder organization, and activations for Salesforce/Google Ads exports. Use when creating audience segments, validating with `tdx sg push --dry-run`, or listing fields with `tdx sg fields`.

Expert guide for creating custom Gemini CLI commands. Covers slash command definitions (.toml), argument parsing, and shell execution. Use when creating custom Gemini commands, defining TOML command files, adding command arguments, or building extension-based commands. Delegates to gemini-cli-docs.

Write semantic, accessible HTML5 markup following best practices for structure, SEO, and accessibility. Use when creating HTML templates, fixing markup issues, or building web page structures.

Authoritative reference for PlantUML diagram syntax. Provides UML and non-UML diagram types, syntax patterns, examples, and setup guidance for generating accurate PlantUML diagrams.

Comprehensive LaTeX documentation from Wikibooks - server-rendered HTML with full tutorial content

Analyze OSS-Fuzz incremental build and JVM RTS (Regression Test Selection) test logs. Use when user mentions RTS logs, test failures, build failures, log analysis, or when working with *.log files from JVM RTS tests. Extracts errors, failed test classes, and categorizes issues.

This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.

Validates CDP segment YAML configurations against the TD CDP API specification. Use when reviewing segment rules for correctness, checking operator types and values, or troubleshooting segment configuration errors before pushing to Treasure Data.

Manage Home Assistant server configuration, automations, and HomeKit Bridge integration. Use when working with YAML configuration, creating automations, troubleshooting entities, or exposing devices to Apple Home. Covers configuration splitting, packages, Jinja2 templates, entity registries, and Docker deployments.
