another day of microsoft trying to make their ai act like a senior dev. now you can apparently feed it custom instructions and skills for your repo so it actually knows what it is looking at. they are pushing this mcp server thing too, using playwright to let the agent crawl stuff or whatever. sounds great until you realize how much garbage context you end up bloating the prompt with. i tried adding some basic repo rules last week and it just hallucinated more than usual. if we start connecting every tool via mcp it is just going to be a nightmare for latency and debugging. plus the security implications of letting an agent run playwright on your codebase are not even funny. probably just another way to make developers lazier while paying a monthly subscription. i doubt this actually helps with complex logic without breaking something else in the process.
