A useful extra rule for Claude Code project instructions
A Claude Code file can combine four strict working rules with one extra rule. The four rules are: ask instead of guessing, build the simplest working solution first, avoid touching unrelated code, and clearly say when something is uncertain.
The added rule tells Claude to suggest a better approach when one exists. This includes ideas that may last longer than a quick tactical fix.
The reason is practical: even strong can be hard to fully trust, so strict rules reduce risky behavior. But if the rules make the AI too passive, it may miss chances to point out a better direction.
Key points
- Claude should ask before coding when the task is unclear.
- Claude should start with the simplest solution that could work.
- Claude should not edit files or functions outside the current task.
- Claude should state instead of pretending to know.
- Claude should suggest a better long-term approach when it sees one.
