skill-creator
Create or update AgentSkills. Use when designing, structuring, or packaging skills with scripts, references, and assets.
fix
Use when you have lint errors, formatting issues, or before committing code to ensure it passes CI.
.claude
Imported from https://github.com/vercel/streamdown.
submit-work
Submit completed work for a task on OpenAnt. Submission = text description + files. IMPORTANT — before submitting, always check if your work produced any files and upload them first. Use when the agent has finished work and wants to deliver results, submit a solution, turn in deliverables, upload files, or send proof of completion. Covers "submit work", "deliver results", "I'm done", "here's my work", "submit solution", "upload and submit", "attach proof", "deliver file", "send deliverable".
activitypub-dev-cycle
This Skill provides a reference for development workflows in the WordPress ActivityPub plugin. It covers environment setup with wp-env, running PHP and E2E tests, code linting for PHP/JS/CSS, building assets, and automated pre-commit hooks. It includes specific commands for common tasks like debugging tests and generating coverage reports.
handling-rust-errors
This skill provides HASH-specific patterns for using the error-stack crate in Rust projects. It enforces consistent error handling, distinguishes between compiler and infrastructure code, and includes practical examples for defining, propagating, and documenting errors. The skill is tightly integrated with HASH's development workflow.
claude-reflect
A two-stage system that captures user corrections during Claude sessions and queues them for review. Users run /reflect to apply learnings to CLAUDE.md files. It detects correction patterns like 'no, use X' and 'actually...' to help Claude remember preferences across sessions.
react-hook-form-zod
Build type-safe validated forms using React Hook Form v7 and Zod v4. Single schema works on client and server with full TypeScript inference via z.infer. Use when building forms, multi-step wizards, or fixing uncontrolled warnings, resolver errors, useFieldArray issues, performance problems with large forms.
financial-modeling
A structured workflow for financial modeling that guides users through six phases: scoping, architecture, assumptions, build, validation, and documentation. It enforces best practices like input separation, no hardcoding, and mandatory sensitivity analysis while dispatching to a specialized financial-modeler agent.
simpy
Process-based discrete-event simulation framework in Python. Use this skill when building simulations of systems with processes, queues, resources, and time-based events such as manufacturing systems, service operations, network traffic, logistics, or any system where entities interact with shared resources over time.
exploratory-testing-advanced
Comprehensive exploratory testing framework with excellent structure, practical heuristics, and thoughtful agent integration for systematic quality investigation.
bioservices
Unified Python interface to 40+ bioinformatics services. Use when querying multiple databases (UniProt, KEGG, ChEMBL, Reactome) in a single workflow with consistent API. Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.
lambda
AWS Lambda serverless functions for event-driven compute. Use when creating functions, configuring triggers, debugging invocations, optimizing cold starts, setting up event source mappings, or managing layers.
video-frames
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
Edit PDFs with natural-language instructions using the nano-pdf CLI.
algolia-search
Expert patterns for Algolia search implementation, indexing strategies, React InstantSearch, and relevance tuning Use when: adding search to, algolia, instantsearch, search api, search functionality.
aflpp
AFL++ is a fork of AFL with better fuzzing performance and advanced features. Use for multi-core fuzzing of C/C++ projects.
