| <h2>Agentic Self-Correction Loop</h2> | |
| <p> | |
| Although code writing can be difficult for small models, making it agentic through a feedback loop (writing code → executing locally → catching exceptions → feeding errors back to the model) allows a 1.5B model to achieve high execution accuracy. | |
| </p> | |
| <p> | |
| If <code>run_code_safely</code> captures a traceback or runtime stderr, it wraps it inside the conversation history and prompts the model with instructions to correct it: | |
| </p> | |
| <div class="tip-box"> | |
| <strong>Traceback Feedback:</strong><br> | |
| <em>"The code execution failed with return code 1. Error logs: NameError: name 'x' is not defined. Correct your code errors and return the complete updated code inside ```python ```."</em> | |
| </div> | |
| </section> | |
| <section class="doc-section" id="sandbox"> | |
| <h2>Sandbox Subprocess Limits</h2> | |
| <p>The code interpreter sandboxes execution inside restricted, resource-constrained subprocesses. It enforces standard execution limits:</p> | |
| <ul> | |
| <li><strong>Timeout Safety:</strong> Terminates infinite loops automatically after 10.0 seconds to prevent thread locking.</li> | |
| <li><strong>Process Isolation:</strong> Cleans up temporary files instantly after the execution returns.</li> | |
| </ul> | |
| </section> | |
| <section class="doc-section" id="vscode"> | |
| <h2>🔌 Visual Studio Code Integration</h2> | |
| <p>You can run the Code Interpreter as a background service and trigger local executions directly from your VS Code editor workspace.</p> | |
| <h3>Step 1: Start the Background Daemon Server</h3> | |
| <p>Execute the local HTTP server in your terminal:</p> | |
| <pre><code>python -m slm_code_interpreter.server</code></pre> | |
| <p>The daemon activates a local REST API listening on port <code>8085</code>.</p> | |
| <h3>Step 2: Run the VS Code Extension Blueprint</h3> | |
| <p>A pre-configured extension is provided under the <code>vscode-extension/</code> directory:</p> | |
| <ul> | |
| <li>Open the extension directory in VS Code.</li> | |
| <li>Press <code>F5</code> to launch a debug instance of the editor.</li> | |
| <li>Highlight any instructions or python code blocks inside your editor workspace, right-click, and select: <strong>"SLM Code Interpreter: Execute Selected Prompt / Code"</strong>.</li> | |
| <li>Monitor execution progress and trace outputs inside the VS Code Output Channel under <strong>"SLM Code Interpreter"</strong>.</li> | |
| </ul> | |
| </section> | |
| <section class="doc-section" id="security"> | |
| <h2>Security Warnings</h2> | |
| <div class="security-box"> | |
| <strong>🔒 Subprocess Isolation:</strong> Because this runs code locally in your shell environment, never run the Code Interpreter with administrator rights or execute inputs from unauthenticated users. Consider wrapping the execution in Docker containers or firewalled machines for production systems. | |
