Claude Code creator exposes 73% token waste
Anthropic's Boris Cherny revealed on a recent podcast that developers waste up to 73% of their context window on bloated configurations and stale chat history before typing a single prompt. He detailed how poor environment setups—not model degradation—are usually the reason users feel Claude Code gets "dumber" over time.
// ANALYSIS
The persistent "Claude got dumber" complaints finally have a data-backed explanation, and the culprit is entirely user error rather than model performance.
- –14% of the context window is instantly lost to overly verbose CLAUDE.md files that load on every prompt
- –Another 13% is burned by failing to clear out old chat histories before starting new tasks
- –11% of tokens are wasted on forgotten pre-run hooks that fire unnecessarily
- –Cherny advises a lean, "vanilla" setup with minimal customizations, running contrary to how most power users try to configure their environments
