+# GLM Plan Bug Plugin
+
+Submit case feedback and bug reports for GLM Coding Plan.
+
+Attention: 
+
+- This plugin is designed to work specifically with the GLM Coding Plan in Claude Code.
+- This plugin requires Node.js to be installed in your environment.
+
+## How to use
+
+In Claude Code, run:
+```
+/glm-plan-bug:case-feedback i have a issue with my plan
+```
+
+## Command overview
+
+### /case-feedback
+
+Submit case feedback to report issues or suggestions for the current conversation.
+
+**Execution flow:**
+1. Command `/case-feedback` triggers `@case-feedback-agent`
+2. The agent invokes `@case-feedback-skill`
+3. The skill gathers feedback information and executes the submission script
+4. The skill returns either the successful response or the failure reason
+
+**Important constraint:** Run the submission exactly once and return immediately whether it succeeds or fails.
