Claude
Claude holds long inputs well and follows written constraints closely, which makes it a good fit for code review, editing and any task where the instruction list is long. It reacts strongly to explicitly marked sections, so wrapping input in tags or clear delimiters improves results more than rewording the instruction. A CLAUDE.md file in a repository is read by Claude Code on every session and is the right place for project rules.

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.
