What is the benefit of using the /compact command?

It summarizes long conversation histories, clearing out token-heavy context while retaining the essential details needed to continue the work without hitting context limits.

When should I use 'ultrathink' or 'megathink'?

Use these keywords for high-complexity tasks such as architectural decisions, security audits, or deep debugging where standard reasoning might miss subtle edge cases.

How does the WHAT-WHY-HOW pattern help?

It structures your request so Claude understands the primary objective, the business motivation, and the technical constraints, significantly reducing the need for follow-up corrections.

What are @ mentions in Claude Code?

They are context injection shortcuts (like @file, @folder, or @git) that allow you to feed specific parts of your codebase or documentation into Claude for more accurate analysis.

How do success criteria improve AI code generation?

By explicitly listing 'Done when' conditions, you provide Claude with a checklist to validate its own output against your specific functional and testing requirements before completion.
