Resources
These are the docs and tools that come up in this site's posts and code. If you are new, start with the Claude Code docs. If something suddenly behaves differently, check the changelog first. The end of Opus 4.8 fast mode also showed up in the changelog first.
How to use them
- Official docs: features and commands change often, so treat the docs, not posts, as the source of truth.
- MCP tools: before connecting, check whether a key is needed and what permissions it uses. The MCP post has more detail.
- Playwright: this site's automated checks use the Playwright library to open screens and measure pixels.
- Astro: handles static pages and page transitions.
