Catalog
Every x402, MPP, MCP, and skill listing we've indexed, normalized, and enriched.
Normalize loudness across podcast, lesson, or video batches before publishing
Uses ffmpeg-normalize to batch-normalize audio levels so an agent can hand off consistent output without opening a DAW or touching every file by hand. It fits pipelines that need EBU R128, RMS, or peak targets across mixed media before delivery.
Normalize international phone numbers into E.164 before CRM imports or messaging workflows
Use libphonenumber-js when an agent needs to clean messy phone-number input, validate it against country rules, and return a stable E.164 value before storing contacts or triggering downstream messaging. The skill is about normalization and validation, not telephony delivery, cal
Normalize dbt SQL and Jinja templates into consistent review-ready style with sqlfmt
Use sqlfmt to reformat dbt-oriented SQL and Jinja-heavy query files into a stable style before code review, CI checks, or agent-generated handoff.
Normalize raw CLI output into JSON for reliable downstream parsing and automation
Uses jc to turn command output and supported file formats into structured JSON so an agent can filter, diff, validate, and store results without brittle regex parsing. Best when a workflow already depends on standard CLI tools but needs machine-readable output for the next step.
Normalize article metadata from URLs before generating link previews or content briefs
Uses metascraper to turn a URL plus its fetched HTML into normalized fields such as title, description, author, date, publisher, and lead image. This is useful when an agent needs reliable preview or briefing data from a page without building a custom parser for every site.
Normalize and filter noisy URL lists before crawling or queueing
Uses Courlan to clean, normalize, de-track, and language-filter raw URL inventories before a crawler, scraper, or analyst queue touches them. Best when an agent already has too many candidate links and needs a smaller, cleaner frontier, not a full crawling stack.
Nodriver Async Undetected Chrome Browser Automation for Python
Nodriver is the official successor to Undetected-Chromedriver, providing async browser automation that communicates directly with Chrome DevTools Protocol without Selenium or WebDriver dependencies. Built for stealth web automation that bypasses anti-bot systems including Cloudfl
Nodemailer Node.js Email Sending Library with SMTP and Transport Support
Nodemailer is the most widely used Node.js library for sending emails, with 17k+ GitHub stars and 7 million weekly npm downloads. It supports SMTP, OAuth2, HTML content, attachments, embedded images, and custom transports for services like SES and SendGrid.
NocoDB Self-Hosted No-Code Database Platform with REST API
NocoDB turns any SQL database into a smart spreadsheet with a full REST API. It provides a self-hosted Airtable alternative that connects to PostgreSQL, MySQL, SQLite, and other databases, enabling no-code data management with automation, collaboration, and API-first access.
NocoBase Extensible AI-Powered No-Code and Low-Code Platform
NocoBase is the most extensible open-source no-code/low-code platform for building business applications. It features a data model-driven architecture, AI employee integration, plugin system, and WYSIWYG interface builder.
Nock HTTP Server Mocking and Expectations Library for Node.js
Nock is an HTTP server mocking and expectations library for Node.js that intercepts outgoing HTTP requests and provides programmable responses. With over 13,000 GitHub stars and 5.5 million weekly npm downloads, it is one of the most widely used testing utilities in the JavaScrip
Nix Flake Configuration Builder
Generates reproducible Nix flake configurations with devShell environments and package overlays. Uses the Nix Flakes API, nixpkgs lib functions, and flake-utils for cross-platform builds.
Nitro Next-Generation Universal Server Toolkit by UnJS
Nitro is a universal server framework from the UnJS ecosystem that lets you build and deploy web servers to any JavaScript runtime — Node.js, Deno, Bun, Cloudflare Workers, Vercel, or Netlify — from a single codebase with automatic code-splitting and tree-shaking.
Nightwatch.js Integrated Browser and Mobile Testing Framework
A source-backed ASE skill for Nightwatch.js, the Node.js automation framework for end-to-end, component, API, accessibility, and mobile testing through the W3C WebDriver stack. It fits agent workflows that need repeatable browser control, cross-browser assertions, and CI-friendly
Nginx Error Pattern Analyzer
Analyzes Nginx error logs using GoAccess and custom regex parsers to identify recurring 502/503 patterns. Correlates upstream timeout errors with backend service health via Prometheus PromQL queries.
Nginx Error Log Runbook Agent
Automates Nginx error diagnosis using nginx -T configuration dump, error.log pattern matching, and the Nginx Plus REST API /api/8/http/upstreams endpoint. Resolves 502 Bad Gateway, SSL handshake failures, and upstream timeout issues.
Nginx Error Log Pattern Analyzer
Parses Nginx error logs using configurable regex patterns and the GoAccess real-time log analyzer API. Clusters recurring 502/504 errors and correlates with upstream health check failures.
Nginx Error Log Parser
Parses nginx error.log and access.log files using pattern matching for 5xx status codes, upstream timeouts, and SSL handshake failures. Correlates error spikes with nginx -T configuration dumps to identify misconfigured proxy_pass and keepalive settings.
Nginx Error Log Classifier
Classifies and prioritizes Nginx error log entries using pattern matching against known error signatures and the GoAccess real-time log analyzer. Maps upstream timeout patterns to specific backend service degradation.
Nginx Error Log Analyzer
Parses and diagnoses Nginx error logs and access logs using pattern matching against known error signatures. Integrates with the Nginx Plus REST API /api/8/ endpoints for real-time upstream health, connection metrics, and SSL certificate expiration monitoring.
Nginx Error Log Analyzer and Fixer
Parses Nginx error logs and access logs to diagnose 502, 504, and 413 errors. Uses GoAccess for real-time log visualization and integrates with nginx -t for configuration validation.
Nginx Config Validator Runbook
Validates Nginx configurations using nginx -t syntax checking, the crossplane Python parser for structural analysis, and gixy security analyzer. Detects misconfigurations, SSL issues, and security vulnerabilities.
Nginx Config Validator and Optimizer
Parses nginx.conf and included config files using the crossplane Python library and nginx -t test command. Identifies misconfigurations, duplicate server blocks, SSL/TLS weaknesses via Mozilla SSL Configuration Generator recommendations.
Nginx Config Linter and Tester
Validates nginx.conf files using the gixy static analyzer and crossplane parser library. Tests configuration for security misconfigs, HTTP header issues, and performs dry-run validation via nginx -t subprocess invocation.
