Standards and methods for conducting research, gathering information, and presenting findings with proper source attribution. Use when researching topics, analyzing documentation, or synthesizing information from multiple sources.

Automates updating googleai_dart when Google AI OpenAPI spec changes. Fetches latest spec, compares against current, generates changelogs and prioritized implementation plans. Use for: (1) Checking for API updates, (2) Generating implementation plans for spec changes, (3) Creating new models/endpoints from spec, (4) Syncing local spec with upstream. Triggers: "update api", "sync openapi", "new endpoints", "api changes", "check for updates", "update spec", "api version", "fetch spec", "compare spec", "what changed in the api", "implementation plan".

Generate Japanese documentation from spec files. Use AUTOMATICALLY after writing or editing any file matching specs/**/*.md (excluding specs/**/docs/*). Also use when user says "generate spec docs", "spec docs", "PM docs", "architect docs", or "implementation guide". (user)

Perform Google searches to retrieve up-to-date information from the web. Use when users need current information, latest news, technical trends, documentation lookups, or general web searches that require real-time data beyond your knowledge cutoff.

Use when you need the WLILO look (White Leather + Industrial Luxury Obsidian) across HTML, SVG, and jsgui3. Covers token schema, palette, and how to write back design learnings so other agents reuse them. Triggers: wlilo, white leather, industrial luxury, obsidian, design system, palette, theme tokens, diagram styling.

Generates technical implementation plans and architectural strategies that enforce the Project Constitution. Use when designing new features, starting implementation tasks, refactoring code, or ensuring compliance with critical standards like Testability-First Architecture, security mandates, testing strategies, and error handling.

Calculates context-appropriate quality gate thresholds based on work type (Feature/Bug/Hotfix/Docs/Refactor). Ensures rigorous standards for features, pragmatic standards for hotfixes, and 100% test pass rate for all work.

Use this skill when writing Python code following PEP 8 and modern Python best practices.
