This comprehensive guide provides methods for implementing deep observability for Replit deployments. It covers building detailed health check endpoints (tracking uptime, memory, and DB status), setting up structured JSON logging, detecting cold start events, and configuring external alerting mechanisms (e.g., UptimeRobot, Slack). Use this when building robust, production-grade applications that require continuous performance monitoring and reliability tracking.

Implements schema.org JSON-LD across webpages so search engines grasp content intent and serve rich results like FAQs, breadcrumbs, and products, with validation checklists and contextual guidance.

Runs AgentShield to audit Claude Code configuration files and MCP components for secrets, injection risks, and overly permissive settings, offering CLI, JSON/Markdown/HTML reports, auto-fix, Opus deep analysis, and CI-ready GitHub Action hooks to harden new or existing projects.

This guide provides comprehensive patterns for optimizing Turborepo build pipelines within monorepos. It covers local and remote caching strategies, including integration with Vercel and self-hosted solutions. Use it when setting up new monorepos, improving CI/CD performance, or debugging complex build dependency issues.

Workflow for parsing SillyTavern-compatible character cards and world info from PNG/WebP/JSON files using a dedicated Node.js parser, with clear steps for copying presets, installing deps, running the extractor, and verifying results.

Analyzes a code repository to generate a recommended, minimal set of read-only shell command permissions for Claude Code's settings.json. It automatically detects the project's tech stack (e.g., Python, Node.js, Go), build tools, and monorepo structure, ensuring a safe and evidence-based security baseline for new projects or auditing existing permissions.

This skill guides the process of auditing and correcting critical HTML metadata elements, ensuring optimal performance for search engines and social media sharing. It covers page titles, meta descriptions, canonical URLs, Open Graph tags, Twitter cards, favicons, JSON-LD structured data, and robots directives. Use this when implementing or refining SEO metadata, fixing broken social previews, or setting up structured data.

This skill provides methods for reliably extracting typed, validated, and structured data from Large Language Models (LLMs), moving beyond simple text parsing. It covers best practices across major APIs (OpenAI's response_format, Anthropic's tool_use, Google's responseSchema) and local models. Key workflows include defining schemas (Pydantic/Zod), implementing constrained decoding, and building robust retry loops for production-grade data pipelines.

This comprehensive tool validates Claude Code plugins against official Anthropic specifications and internal enterprise standards. It performs two main types of checks: structural validation (checking `plugin.json` fields, file references, and permissions) and content validation (conducting deep grading using `SKILL.md`). Use this when building, auditing, or preparing plugins for marketplace submission to ensure compliance and quality.

A comprehensive design specification detailing 98 rules for building Command Line Interface (CLI) tools that are safe, reliable, and easily consumable by AI agents. It covers structured JSON output formats, standardized error handling (to stderr), robust input contracts, safety guardrails (e.g., preventing path traversal), and tiered compliance levels (Agent-Friendly, Agent-Ready, Agent-Native) for seamless integration into AI workflows.

This skill provides a programmatic method for analyzing Advanced Persistent Threat (APT) groups using the MITRE ATT&CK framework. By querying TTPs and generating multi-layer JSON files compatible with ATT&CK Navigator, analysts can visualize threat actor coverage, map detection capabilities, and identify critical security gaps to build highly targeted, threat-informed defenses.

This skill provides comprehensive knowledge on using JSON Web Tokens (JWT) for secure authentication and authorization. It covers implementing various cryptographic signing algorithms (such as HS256, RS256, ES256, and EdDSA), validating signatures, enforcing claim constraints (like expiration time), and implementing robust defenses against common JWT vulnerabilities, including algorithm confusion and the 'none' algorithm attack. Ideal for building secure, scalable web APIs.
