[Bug] Context window exhaustion with single MCP enabled and inconsistent claude.md adherence

Bug Description
too slow, and keeps running out of context even though I'm only using 1 mcp - context7; all other mcps have been disabled. doesn't seem to follow claude.md consistently - it should refresh it's claude.md regularly. code is way too verbose - we need short/simple code. also a lot of hackiness built-in that you find out much later - when doing unit and regression tests, it has a tendency to use hacks/silent exception handling to pass the test - it's incentivized to pass tests but not to achieve objectives. I've caught it making up test cases (non-valid) and saying it's successfully finished testing.
