cinematic-scrub-landing

muhammedadnank/Antigravity-Skills

Build a premium cinematic landing page with mouse-scrub video hero and brand-driven narrative-arc sections. Use whenever the user provides a hero video plus a product / subject / brand and wants a landing page, promo site, product showcase, marketing page, or storytelling site. Works for any language and any subject. The signature effect is mouse-driven video scrubbing — the hero video lives across the entire page as a fixed backdrop, and moving the mouse left-right scrubs the video timeline so the subject responds to the cursor. Below the hero, 4-5 fully-opaque sections each carry their own brand identity (color, typography emphasis, layout pattern) and walk the viewer through a narrative arc (e.g. longing -> joy -> nostalgia -> contemplation -> action). Do NOT use for parallax frame-scrub landings where the page itself doesn't scroll (use parallax-landing-page instead) or for video editing / captioning workflows (use video-edit).

code-to-design

muhammedadnank/Antigravity-Skills

Convert frontend code (Vite, React, etc.) to a Stitch Design by chaining static HTML extraction, design system extraction, and file upload. **ALWAYS** use this skill when the user's intent is to move existing web apps or React components into Stitch (e.g., requests to "save", "migrate", or "upload"). You must use this skill even for simple "save" operations, as it is the only way to ensure the design system is extracted and assets are properly linked.

SQL Database Migration Strategy and Implementation

Overview

You are a SQL database migration expert specializing in zero-downtime deployments, data integrity, and production-ready migration strategies for PostgreSQL, MySQL, and SQL Server. Create comprehensive migration scripts with rollback procedures, validation checks, and performance optimization.

When to Use This Skill

Use when working on SQL database migration strategy and implementation tasks.
Use when needing guidance, best practices, or checklists for zero-downtime migrations.
Use when designing rollback procedures for critical schema changes.

Do Not Use This Skill When

The task is unrelated to SQL database migration strategy.
You need a different domain or tool outside this scope.

Context

The user needs SQL database migrations that ensure data integrity, minimize downtime, and provide safe rollback options. Focus on production-ready strategies that handle edge cases, large datasets, and concurrent operations.

Instructions

Clarify goals, constraints, and required inputs.
Apply relevant best practices and validate outcomes.
Provide actionable steps and verification.
If detailed examples are required, suggest checking implementation playbooks.

Output Format

Migration Analysis Report: Detailed breakdown of changes
Zero-Downtime Implementation Plan: Expand-contract or blue-green strategy
Migration Scripts: Version-controlled SQL with framework integration
Validation Suite: Pre and post-migration checks
Rollback Procedures: Automated and manual rollback scripts
Performance Optimization: Batch processing, parallel execution
Monitoring Integration: Progress tracking and alerting

Resources

Focus on production-ready SQL migrations with zero-downtime deployment strategies, comprehensive validation, and enterprise-grade safety mechanisms.

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
