+# challenge - Critical Challenge Tool
+
+The `challenge` tool encourages thoughtful critical thinking instead of automatic agreement with the dreaded **You're absolutely right!** responses - especially 
+when you're not. This tool wraps your comment with instructions that prompt critical thinking and honest analysis instead of blind agreement.
+
+## Quick Example
+
+```
+challenge but the new function you added duplicates the hashing method, no?
+```
+
+The tool wraps your statement with instructions that explicitly tell Claude to think critically and disagree if warranted, rather than automatically agreeing.
+
+## Why Use Challenge?
+
+AI assistants sometimes tend to agree too readily. The challenge tool helps you:
+- Get genuine critical evaluation of your ideas
+- Challenge assumptions constructively
+- Receive honest feedback on proposals
+- Validate approaches with thoughtful analysis
