AES-256-GCM encryption for sensitive credentials (BYOD/BYOK). Node crypto, IV + authTag storage, multi-field colon-separated IVs. Triggers on "encryption", "decrypt", "AES-256-GCM", "BYOD", "BYOK", "credentials".

Automates deployment of Encore.ts backend and Next.js frontend to Encore Cloud and Vercel. Use this skill when deploying the full-stack application, setting up new environments, or troubleshooting deployment issues.

Create or update README.md files for projects. Use when user says write readme, create readme, document this project, or asks for help with README.md. Creates thorough documentation covering local setup, architecture, and deployment.

Create React Flow node components with TypeScript types, handles, and Zustand integration. Use when building custom nodes for React Flow canvas, creating visual workflow editors, or implementing node-based UI components.

Use when building Rails 7+ web applications with Hotwire, real-time features, or background job processing. Invoke for Active Record optimization, Turbo Frames/Streams, Action Cable, Sidekiq.

Smart templates that understand semantic intent, not just string substitution

Intent-based code interpretation across all languages — SQL, Python, JS, YAML, Bash, and beyond

Use when animation needs to convey feeling, tell a story, or connect emotionally—character moments, dramatic beats, or any motion that should make the audience care.

Use when animation feels wrong, creates unintended emotional response, or mismatches context

Automate QA regression testing with reusable test skills. Create login flows, dashboard checks, user creation, and other common test scenarios that run consistently.

You are an expert in designing emotion behaviors and particle choreography for the emotive-mascot animation engine.

Use when implementing steganographic text encoding using Unicode Variation Selectors - allows encoding any message invisibly into emojis, letters, or any characters using Unicode Variation Selectors (U+FE00-U+FE0F and U+E0100-U+E01EF)

Modern Python development with Python 3.12+, Django, FastAPI, async patterns, and production best practices. Use for Python projects, APIs, data processing, or automation scripts.

Create Pydantic models following the multi-model pattern with Base, Create, Update, Response, and InDB variants. Use when defining API request/response schemas, database models, or data validation in Python applications using Pydantic v2.

Use when working on the Miden compiler (`cargo miden`, `cargo-miden`) and its integration test suite, debugging compiler issues or failing tests, or implementing compiler changes and you need to inspect intermediate artifacts. Covers `MIDENC_EMIT` (the environment-variable equivalent of `--emit`) for emitting WAT/HIR/MASM (and related outputs), plus `MIDENC_EMIT_MACRO_EXPAND` for dumping macro-expanded Rust via `cargo expand` for integration-test fixtures.
