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.
app-store-optimization
Complete App Store Optimization (ASO) toolkit for researching, optimizing, and tracking mobile app performance on Apple App Store and Google Play Store
git-commit-validator
Validates git commit messages against conventional commit format with character limits and content restrictions. Includes a shell script for automated checking and provides clear examples of valid/invalid messages. Focuses on preventing AI attribution and maintaining clean git history.
codebase-navigation
Provides structured patterns for exploring unfamiliar codebases using Glob and Grep commands. Guides developers through systematic discovery of project structure, entry points, and dependencies. Includes practical examples for finding implementations, tracing usage, and mapping architecture across different programming languages.
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.
getting-started-guide
A guided onboarding skill for a novel writing tool. It activates when users express intent to start a new project and walks them through a seven-step methodology (constitution, specify, clarify, plan, tasks, write, analyze). It provides clear explanations, answers common questions, and offers practical first-use advice.
qa-resilience
Provides concrete patterns for testing system resilience including circuit breakers, retry strategies, timeout policies, and chaos experiments. Includes decision trees, library recommendations, and anti-patterns to avoid. Focuses on validating degraded modes and production guardrails.
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.
secure-workflow-guide
Guide you through Trail of Bits' 5-step secure development workflow. Runs Slither scans, checks special features (upgradeability/ERC conformance/token integration), generates visual security diagrams, helps document security properties for fuzzing/verification, and reviews manual security areas. (project, gitignored)
variant-analysis
Find similar vulnerabilities and bugs across codebases using pattern-based analysis. Use when hunting bug variants, building CodeQL/Semgrep queries, analyzing security vulnerabilities, or performing systematic code audits after finding an initial issue.
fix-review
Verifies that git commits address security audit findings without introducing bugs. This skill should be used when the user asks to "verify these commits fix the audit findings", "check if TOB-XXX was addressed", "review the fix branch", "validate remediation commits", "did these changes address the security report", "post-audit remediation review", "compare fix commits to audit report", or when reviewing commits against security audit reports.
Writing Documentation for LLMs
This skill teaches developers how to write documentation specifically for LLMs. It emphasizes assuming LLM competence, using progressive disclosure, prioritizing examples over explanations, and building validation into workflows. The guide provides concrete patterns like table of contents organization, conditional workflows, and verifiable outputs.
exploratory-testing-advanced
Comprehensive exploratory testing framework with excellent structure, practical heuristics, and thoughtful agent integration for systematic quality investigation.
scikit-bio
This skill provides access to scikit-bio, a Python library for biological data analysis. It handles sequence manipulation, alignments, phylogenetic trees, diversity metrics (alpha/beta, UniFrac), ordination (PCoA), statistical tests (PERMANOVA), and common file formats (FASTA, Newick, BIOM). The documentation includes specific code patterns for common bioinformatics tasks and troubleshooting guidance.
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.
pydeseq2
This skill enables differential gene expression analysis in Python using the PyDESeq2 library. It provides workflows for loading RNA-seq count data, specifying experimental designs, running statistical tests, and generating results with multiple testing correction. The documentation includes troubleshooting for common errors like design matrix issues and memory management tips.
flowio
Parse FCS (Flow Cytometry Standard) files v2.0-3.1. Extract events as NumPy arrays, read metadata/channels, convert to CSV/DataFrame, for flow cytometry data preprocessing.
semgrep-rule-creator
Create custom Semgrep rules for detecting bug patterns and security vulnerabilities. This skill should be used when the user explicitly asks to "create a Semgrep rule", "write a Semgrep rule", "make a Semgrep rule", "build a Semgrep rule", or requests detection of a specific bug pattern, vulnerability, or insecure code pattern using Semgrep.
writing-hashql-jexpr
This skill provides detailed guidance for writing HashQL J-Expr, a JSON-based query syntax. It covers expression types, data constructors, function calls, and common patterns with clear examples. The documentation includes syntax reference and type system details, making it useful for developers working with HashQL query files.
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.
ecs
AWS ECS container orchestration for running Docker containers. Use when deploying containerized applications, configuring task definitions, setting up services, managing clusters, or troubleshooting container issues.
cloudflare-mcp-server
Build MCP servers on Cloudflare Workers - the only platform with official remote MCP support. TypeScript-based with OAuth, Durable Objects, and WebSocket hibernation. Prevents 24 documented errors. Use when: deploying remote MCP servers, implementing OAuth, or troubleshooting URL path mismatches, McpAgent exports, CORS issues, IoContext timeouts.
google-gemini-api
Integrate Gemini API with @google/genai SDK (NOT deprecated @google/generative-ai). Text generation, multimodal (images/video/audio/PDFs), function calling, thinking mode, streaming. 1M input tokens. Prevents 14 documented errors. Use when: Gemini integration, multimodal AI, reasoning with thinking mode. Troubleshoot: SDK deprecation, model not found, context window, function calling errors, streaming corruption, safety settings, rate limits.
bunjs-architecture
Provides concrete patterns for building Bun.js TypeScript backends with layered architecture. Enforces strict separation of concerns (routes, controllers, services, repositories) and mandates camelCase naming across the stack. Includes detailed workflows for database design, API endpoints, and implementation phases.
