Automatically generates executable tests that reproduce reported bugs from issue reports and code repositories. Use when users need to: (1) Create a test that reproduces a bug described in an issue report, (2) Generate failing tests from bug descriptions, stack traces, or error messages, (3) Validate bug reports by creating reproducible test cases, (4) Convert issue reports into executable regression tests. Takes a repository and issue report as input and produces test code that reliably triggers the reported bug.

Use the ClawHub CLI to search, install, update, and publish agent skills from clawhub.com. Use when you need to fetch new skills on the fly, sync installed skills to latest or a specific version, or publish new/updated skill folders with the npm-installed clawhub CLI.

This skill provides comprehensive instructions for interacting with the Raindrop.io bookmarks service via its REST API using curl and jq. It covers authentication, CRUD operations for collections, raindrops (bookmarks), tags, highlights, filters, import/export, and backups. Use this skill whenever the user asks to work with their bookmarks from Raindrop.io, including reading, creating, updating, deleting, searching, or organising bookmarks and collections.

Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.

Runs load tests, profiles application bottlenecks, analyzes response time metrics, and generates performance optimization recommendations. Use when you need to benchmark a system, run load or stress tests, measure latency or throughput, identify performance bottlenecks, optimize Core Web Vitals (LCP, FID, CLS), plan capacity, enforce performance budgets in CI/CD pipelines, or investigate slow API response times, database query performance, or frontend rendering delays.

Performs authorized post-exploitation activities to assess impact, lateral movement paths, credential exposure, and detection gaps after initial compromise. Use when a foothold has been validated and the test requires controlled impact expansion analysis.

Extracts Mermaid diagrams from markdown files and generates high-quality PNG images using bundled scripts. Activates when working with Mermaid diagrams, converting diagrams to PNG, extracting diagrams from markdown, or processing markdown files with embedded Mermaid code.

Register agents on the zScore ERC-8004 Identity Registry, manage wallets and metadata, and read on-chain state. Use when an agent needs to register on-chain, check fees, read agent info, set metadata, or manage agent wallets on Base Mainnet or Base Sepolia.

Integrate Dojo with game clients for JavaScript, Unity, Unreal, Rust, and other platforms. Generate typed bindings and connection code. Use when connecting frontends or game engines to your Dojo world.

Perform a comprehensive code security review against the 2025 MITRE CWE Top 25 Most Dangerous Software Weaknesses (sourced from https://cwe.mitre.org/top25/). Use this skill every time the user asks for a code security review, security audit, vulnerability scan, CWE review, secure code review, source review, or any variant of "check my code for security issues". This skill runs 25 dedicated analysis passes -- one per CWE in the Top 25 -- each focused on finding ALL instances of its assigned weakness across the entire codebase. Results are risk-ranked from highest to lowest and every finding includes a specific, actionable remediation recommendation grounded in good software security engineering practice and principles.

Comprehensive toolkit for survival analysis and time-to-event modeling in Python using scikit-survival. Use this skill when working with censored survival data, performing time-to-event analysis, fitting Cox models, Random Survival Forests, Gradient Boosting models, or Survival SVMs, evaluating survival predictions with concordance index or Brier score, handling competing risks, or implementing any survival analysis workflow with the scikit-survival library.

Deploy to Cloudflare (Workers, R2, D1), Docker, GCP (Cloud Run, GKE), Kubernetes (kubectl, Helm). Use for serverless, containers, CI/CD, GitOps, security audit.

Generate Harness Connector YAML for integrations and create/test via MCP. Use when user says "create connector", "git connector", "aws connector", "docker connector", "cloud connector", or wants to connect Harness to external services.

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.

Queries Tilt resource status, logs, and manages dev environments. Use when checking deployment health, investigating errors, reading logs, or working with Tiltfiles.

Vitess best practices, query optimization, and connection troubleshooting for PlanetScale Vitess databases. Load when working with Vitess databases, sharding, VSchema configuration, keyspace management, or MySQL scaling issues.
