Cursor rules, Cline tools, Copilot instructions, and custom commands all have a home in Claude Code. Where each one goes, what /init and /import carry over, and the pieces other tools don't have.

Claude Code and the Claude chat apps draw from the same five-hour and weekly limits on Pro and Max. The one exception since September, why Opus 5.5 drains it faster, and how to check what's left.

Code can be rolled back. A dropped column can't. Where Prisma draws the line between development and production commands, how to keep Claude away from your real database, and the rules that keep migrations safe.

It re-reads a file it already read and loses a rule you set an hour ago. Nothing is broken: the conversation got compacted. What survives that summary, what does not, and why /clear and /compact are not the same tool.

Deny beats allow no matter how specific the allow is, one space changes what a Bash rule matches, and a leading slash doesn't mean your drive root. The settings.json permission syntax, with the cases that trip people up.

It runs on Windows, macOS, and Linux and feels nearly the same on all three. Four differences are real, and three of them will eventually cost you an afternoon.

The file-lock crash has siblings. The GPU crash from the in-app browser, the 'This app can't open' package flag, the service that blocks self-repair, and the CLI freeze, each with its log signature and a fix shorter than Windows Repair.

The third orphaned-process crash in the Windows desktop app. If you use Claude Code on remote servers, a hung ssh.exe survives the app closing and holds the pipe the next session needs. End it in Task Manager, then stop it happening with one ssh flag.

The common Claude Code errors with the exact message text, what actually causes each one, and the fix. Includes a desktop app crash that has no writeup anywhere else.

If the desktop app dies every time you use the browser and only Windows Repair brings it back, the install is fine. An orphaned process is holding a file lock, and one taskkill command fixes it in a second.

A CLAUDE.md is the highest-leverage file you can add to a Claude Code project, and most people either skip it or bloat it. Here's what to put in it, where to put it, how to write instructions Claude actually follows, and how to keep it lean.

Opus 5 lets you set how hard it thinks, and the instinct to crank it to max will cost you real money for nothing. A plain-English guide to the effort dial, why medium usually wins, and what the benchmarks actually found.

A beginner-friendly walkthrough of installing Claude Code from scratch on Windows, macOS, and Linux, including the desktop app option that skips the terminal entirely and the few things that trip people up.

Learning the fundamentals sounds like a separate project that competes with shipping, which is why vibe coders keep putting it off. Here's a more realistic path: use the tool you already use all day as your teacher.

That yellow warning about your CLAUDE.md crossing 40K characters is worth taking seriously, but the most common fix people reach for doesn't actually solve the problem. Here's what does.
