A simple wrapper around ffmpeg to extract single frames from videos at specified timestamps. It provides basic command-line examples for getting first frames or frames at specific times, with format recommendations for different use cases.
esm
Comprehensive toolkit for protein language models including ESM3 (generative multimodal protein design across sequence, structure, and function) and ESM C (efficient protein embeddings and representations). Use this skill when working with protein sequences, structures, or function prediction; designing novel proteins; generating protein embeddings; performing inverse folding; or conducting protein engineering tasks. Supports both local model usage and cloud-based Forge API for scalable inference.
fluidsim
Framework for computational fluid dynamics simulations using Python. Use when running fluid dynamics simulations including Navier-Stokes equations (2D/3D), shallow water equations, stratified flows, or when analyzing turbulence, vortex dynamics, or geophysical flows. Provides pseudospectral methods with FFT, HPC support, and comprehensive output analysis.
plugin-workflow
A sophisticated orchestration skill for JUCE plugin development that coordinates multiple specialized subagents through a structured 3-stage workflow with automatic validation and checkpoint management.
skill-creator
A meta-skill that provides templates and scripts for creating other Claude skills. It includes a structured SKILL.md template, validation utilities, and packaging tools to standardize skill development. The skill creator helps developers follow best practices for skill architecture and resource organization.
context-detection
This skill detects project technology stacks by analyzing config files, directory structures, and file extensions. It supports multi-stack detection for fullstack projects and maps findings to specific skill paths for Claude's dev plugin. The detection follows a clear priority order and includes error handling for ambiguous cases.
skill-reinforcement
A meta-skill that automatically triggers after any skill use to capture learnings, identify anti-patterns, and update skill documentation. It provides structured templates for documenting shortcuts, failure modes, and workflow improvements to prevent knowledge loss between sessions.
python
This skill provides detailed guidance for using uv as a Python package manager and project tool. It covers project setup, dependency management, script execution, and Python version control. The documentation includes migration guides from pip/virtualenv, troubleshooting steps, and integration examples with common dev tools.
nano-pdf
