Claude Code's product lead talks usage limits, transparency, and the 'lean harness'

Claude Code's product lead addresses how Anthropic tunes the "harness" (the structural layer around the model) for each new model release to optimize performance and reduce verbosity. The company commits to greater transparency by using a dedicated developer account to explain future product decisions. Anthropic reset usage limits for subscribers following performance issues caused by product-layer bugs rather than model degradation.
