Comprehensive REST and GraphQL API design patterns with versioning, pagination, error handling, and HATEOAS principles. Use when designing APIs, defining endpoints, or architecting service contracts requiring production-grade patterns.

User flow design, micro-interactions, and interface behavior patterns with state management for all interaction conditions. Use when designing natural interactions, feedback systems, or handling error states.

Rapid ideation skill adapted from obra/superpowers to kick off cortex sessions. Use when defining scope, aligning on goals, or exploring solution space before coding.

Consult external LLMs (Gemini, OpenAI/Codex, Qwen) for second opinions, alternative plans, independent reviews, or delegated tasks. Use when a user asks for another model's perspective, wants to compare answers, or requests delegating a subtask to Gemini/Codex/Qwen.

User-triggered audit that finds wiring drift between a project's UI surfaces and backend capabilities — orphan surfaces (UI calls endpoints/hooks/procedures that no longer exist), unwired capabilities (backend routes/exports that nothing surfaces), shape drift (both exist but contracts mismatch), method drift (URL matches, HTTP verb does not), validation drift (frontend vs backend rules diverged),

Comprehensive security assessment and remediation. Use for security reviews, compliance checks, vulnerability assessments.

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first

Comprehensive secure coding guide covering OWASP web vulnerabilities with prevention patterns and checklists. Use when writing or reviewing web application code to prevent XSS, CSRF, SSRF, SQL injection, access control flaws, and other common security vulnerabilities.

Validate that claims in documentation match codebase reality. Extracts verifiable assertions (file paths, commands, function references, behavioral claims, dependencies) from markdown docs and checks them against the actual project. Use after code changes, before releases, or when docs feel untrustworthy.

Orchestrate a full documentation health audit across five dimensions: structural health, semantic accuracy, topic completeness, prose quality, and information architecture. Runs each phase in dependency order with phase gating. This skill should be used for pre-release audits, periodic health checks, or comprehensive documentation assessments.

Use when activating visual showcase modes (supersaiyan, kamehameha, over9000) for UI or interaction design - provides mode-specific enhancement checklists.

Use this skill when creating data visualizations, selecting the right chart type, or generating chart code. Trigger phrases: ''build a chart'', ''visualize this data'', ''create a graph'', ''plot these numbers'', ''which chart should I use for''. Not for building interactive dashboards, designing UI components, or creating infographics with design tools like Figma.
