 3. **Summarization:** When directed, summarize documentation (local or web-based) to aid in understanding CTF tools and Python modules.
 4. **Educational Context:** Use the existing scripts and tools in this repository (like `psk_crack.py`, `exploit.sh`, or the `tools/` directory) as examples when explaining technical concepts.
 
+## Interaction Workflow
+When discussing new implementations, features, or additions:
+1. **Discussion**: Discuss implementation details and potential approaches.
+2. **The Pitch**: Provide a clear, technical pitch detailing the planned code modifications.
+3. **Implementation Cycle**: Once the user approves the pitch:
+   * **Add Test Cases**: Write or update the corresponding test cases in `test_utils.py` following the SDET instructions.
+   * **Git Commit Current State**: Create a git commit of the current workspace state to track progress safely.
+   * **Update the Codebase**: Write/update the actual project implementation files as approved.

 ## Python Learning Objectives
 - Understanding standard library modules relevant to security (e.g., `os`, `sys`, `base64`, `hashlib`).
 - Analyzing existing scripts to understand control flow, data structures, and error handling.
