A new tool called CC-Canary has been released to detect regressions in Claude Code's performance by analyzing session logs. This pre-alpha tool runs locally, requiring no network or telemetry, and provides detailed reports on model drift, including metrics like cost, token usage, and reasoning depth. Separately, users are reporting impressive capabilities with Claude Code, including one instance where it reportedly rewrote 3,000 lines of legacy Python code overnight and potentially invented a new design pattern.
