Accelint Ts Best Practices

gohypergiant/agent-skills
292 installs21 stars
Summary

A comprehensive TypeScript and JavaScript coding standards guide that's laser-focused on type safety and defensive programming. You'd reach for this when reviewing code for anti-patterns, eliminating any types and enums, implementing proper error handling, or applying zero-value patterns instead of null checks. It uses progressive disclosure to avoid context bloat: start with AGENTS.md for rule summaries, then drill into specific references like naming-conventions.md or return-values.md as needed. Each reference shows incorrect versus correct examples with explanations. Includes a formal audit report template with severity levels and impact analysis, though you skip that if you're just fixing a specific type error. Part of a trilogy with separate skills for performance optimization and documentation.

firecrawl

connorads/dotfiles

Search, scrape, and interact with the web via the Firecrawl CLI. Use this skill whenever the user wants to search the web, find articles, research a topic, look something up online, scrape a webpage, grab content from a URL, get data from a website, crawl documentation, download a site, or interact with pages that need clicks or logins. Also use when they say "fetch this page", "pull the content from", "get the page at https://", or reference external websites. This provides real-time web search with full page content and interact capabilities — beyond what Claude can do natively with built-in tools. Do NOT trigger for local file operations, git commands, deployments, or code editing tasks.
