Analyze and optimize individual pages for conversion performance. Use when the user wants to improve conversion rates, diagnose why a page is underperforming, or increase the effectiveness of marketing pages (homepage, landing pages, pricing, feature pages, or blog posts). This skill focuses on diagnosis, prioritization, and testable recommendations— not blind optimization.

Generate interactive daily standup/status updates from GitHub, Jira, and AI session history; use for daily, standup, scrum, status update, yesterday/today/blockers, or team sync.

Curated collection of high-quality prompts for various use cases. Includes role-based prompts, task-specific templates, and prompt refinement techniques. Use when user needs prompt templates, role-play prompts, or ready-to-use prompt examples for coding, writing, analysis, or creative tasks.

Ultra-compressed communication mode — drops filler, articles, pleasantries while keeping technical accuracy. Use when user says "caveman mode", "talk like caveman", "less tokens", "be brief", or invokes /caveman.

Design judgment via design-director taste — reads design intent, assesses whether execution serves it, returns opinionated verdict with clear direction.
