Claude
Claude holds long inputs and follows written constraints closely, so it suits code review, editing and any job with a long instruction list. Marked sections move it a lot. Wrapping the input in tags or clear delimiters improves results more than rewording the instruction does. Claude Code reads a CLAUDE.md file from the repository at the start of every session, which makes that file the right home for project rules.

How to stop repeating the same instructions in every message, and what belongs in a system prompt against what belongs in the task.
Common questions
Where do you put standing rules for Claude?
In CLAUDE.md. It is read on every session, so anything you would otherwise paste into each message belongs there rather than in the conversation.
Do Claude prompts work on other models?
Usually with changes. Every resource here records where it was tested and what to adjust elsewhere, and portable ones are filed under Universal.
