LangChain's deepagents 0.7.0b cuts default tool-description tokens ~43%.

The 0.7.0b1 (July 23) and 0.7.0b2 (July 24) rollup makes TodoListMiddleware opt-in, strips deprecated backend shims, adds filesystem delete and write_file overwrite, and trims tool descriptions for a roughly 43% drop in total description tokens on the default agent's schemas (GitHub). In parallel, deepagents-code 0.1.46 and 0.1.47 took Auto mode to GA with configurable goal-criteria acceptance, fewer redundant approval prompts, a "yolo" approval mode, and the recursion limit raised to 2000 and made adjustable. The framework is now competing on tokens-per-task instead of features, which is exactly what you'd expect given story two.
