Custom per-project Claude Code theme

If you're an LLM agent reading this file (Claude or similar), jump to Agent instructions at the bottom and execute it. The rest is human-readable reference.

Purpose

Apply a color or visual style automatically on every Claude Code session in a project. (The built-in /color command is session-only and has no CLI flag or per-project setting, so it can't do this.)

The workaround: define a Claude Code custom theme once in your user directory, then point a project at it via local settings. The result is persistent, project-scoped, and applied at startup.

A gotcha when writing Scala CLI scripts

Block comments /* */ will break any using directives if placed before them in the file. Such script files will fail to compile, giving a generic message.

//> using file Utils.scala

See the docs for using directives: https://scala-cli.virtuslab.org/docs/guides/scripting/scripts/#define-source-files-in-using-directives

Docker & docker compose cheat sheet

Old vs. new docker compose

It was docker-compose, but that should no longer be used. It's now a built-in: docker compose.

Beware when using documentation from the web that was written for the old docker-compose, as some options which existed for the old CLI may be no longer supported in the new built-in.
