Add a Stapler Squad Rule

Rules in stapler-squad live at .claude/rules/*.md and are automatically loaded by Claude Code for every session in this project. They encode hard-won lessons, required conventions, and anti-patterns that have caused real bugs or failures.

When to Add a Rule

Add a rule when:

• A mistake was made (or nearly made) that a written constraint would have caught
• A non-obvious convention must be followed every time (e.g., always pass a specific flag)
• A "wrong" and "right" pattern exists and the wrong one is easy to accidentally reach for

Do NOT add a rule for:

• Things already documented in ADRs or code comments
• General best practices that aren't stapler-squad-specific
• Anything already covered by an existing rule
