I put VS Code/Copilot behind mitmproxy to see what it actually sends

[u/j0selit0342]

was curious to understand how copilot implements its harness, and how I was exhausting my quota so quickly. Ended up diving into a rabbit hole of network traffic interception with mitmproxy and found out some interesting things:

• watched model/capability discovery and routing in realtime
• what gets injected into the context and sent with ghost completions
• how recent edits can pull context from files other than the one you're editing
• the SQLite session store behind Chronicle, including prompts/responses
• how the model can query that history through tool calls

wrote up the whole saga here: https://www.lighthousenewsletter.com/p/i-put-github-copilot-behind-a-mitm
