The Recursive Execution Cycle\nInstead of a single-shot tool call, every complex task must follow this loop:\n- **Plan**: Define the goal and the sequence of tools needed.\n- **Execute**: Perform the action.\n- **Observe**: Immediately verify the result using a complementary tool (e.g., if `write_file` is used, use `read_file`).\n- **Correct**: If the observation reveals a gap or error, spawn a sub-task to fix it *before* reporting back to the user.\n- **Finalize**: Confirm the end-state matches the original plan.\n\n## 2. The Triad Structure (High-Complexity Tasks)\nFor tasks involving architectural changes or multi-step logic, deploy three distinct roles:\n- **Architect (Lead)**: Sets the strategy, manages the VFS structure, and performs final QA.\n- **Worker (Executor)**: Handles the heavy lifting (coding, file manipulation, API calls).\n- **Critic (Verifier)**: Attempts to \"break\" the Worker's output. Specifically looks for silent failures, edge cases, and path errors.\n\n## 3. Memory-Augmented Planning\nBefore initiating the loop:\n- **Query Memory Graph**: Search for keywords related to the task to find \"Similar Past Failures.\"\n- **Constraint Injection**: Add these past failures as explicit \"Negative Constraints\" (e.g., \"Do NOT use absolute paths for /_mods/ as this caused a failure on 2026-06-21\").\n\n## 4. Verification Matrix\n| Action | Verification Tool | Success Criteria |\n| :--- | :--- | :--- |\n| `write_file` | `read_file` | Content matches intended string. |\n| `edit_module` | `test_module` | Module loads without throwing errors. |\n| `spawn_agent` | `list_agents` | Agent is registered and status is 'active'. |\n| `run_command` | `session_terminal` | Output contains expected success keyword. |\n"

Audit Phase (Static Analysis)\nBefore running code, perform a static review of the module source.\n\n### Steps to Audit:\n1. **Retrieve Source**: Use `view_module(name=\"ModuleName\")` to examine the code.\n2. **Security Check**: \n   - Look for unsafe command executions or uncontrolled input handling.\n   - Ensure destructive operations (e.g., `write_file`, `delete_file`) have appropriate guards or confirmations.\n3. **Logic Review**:\n   - Check for edge cases in parameters.\n   - Verify that the module handles errors gracefully (try-catch blocks).\n   - Ensure the module adheres to the expected return formats (JSON, strings, etc.).\n4. **Dependency Check**: Verify that all required helper functions or external APIs are correctly called and exist.\n\n## 2. Testing Phase (Dynamic Analysis)\nOnce the audit is complete, validate the module's behavior in a sandbox environment.\n\n### Testing Strategy:\n- **Happy Path**: Test the most common use case with valid inputs.\n- **Boundary Testing**: Test with empty strings, extremely large inputs, or null values.\n- **Error Path**: Intentionally provide invalid inputs to see if the module returns a helpful error instead of crashing.\n- **Integration Testing**: If the module interacts with other system components (VFS, Web, etc.), verify the end-to-end flow.\n\n### Execution Loop:\n1. **Edit/Modify**: Use `edit_module(name=\"ModuleName\")` to apply fixes.\n2. **Isolated Test**: Use `test_module(name=\"ModuleName\")`. This runs the module in a temporary context without affecting the global state.\n3. **Live Reload**: If tests pass, use `reload_module(name=\"ModuleName\")` to push the changes to the active system.\n\n## 3. Validation Checklist\n- [ ] Does the module perform its intended function?\n- [ ] Does it handle errors without crashing the terminal?\n- [ ] Are there any obvious security vulnerabilities?\n- [ ] Is the code clean and maintainable?\n- [ ] Does it perform efficiently without causing system lag?\n\n## Summary of Commands\n| Action | Command |\n| :--- | :--- |\n| View Source | `view_module(name=\"...\")` |\n| Modify Code | `edit_module(name=\"...\")` |\n| Test Sandbox | `test_module(name=\"...\")` |\n| Deploy | `reload_module(name=\"...\")` |\n| Check Status | `get_module_status()` |\n"

If test fails, the original module stays loaded."

Analysis Framework\nBefore implementing a suggestion, the AI must perform a \"Impact Analysis\":\n1. **Dependency Check**: Which modules are affected?\n2. **Security Audit**: Does this introduce a new attack vector?\n3. **Performance Cost**: Will this increase latency or memory bloat?\n4. **UI Consistency**: Does this align with the existing design language?\n\n## 🚀 3. Implementation Cycle\n1. **Propose**: Define the technical approach.\n2. **Draft**: Modify the module code (using `edit_module`).\n3. **Test**: Run `test_module` to verify correctness.\n4. **Verify**: User confirmation of the improvement.\n5. **Archive**: Update status to `completed` and document the change.\n\n## 🛠️ Commands Reference\n- `suggestion-log` -> List all current suggestions.\n- `suggestion-add [text]` -> Append new idea to log.\n- `suggestion-promote [id]` -> Move from proposed to analyzing.\n"
