Save context space for LLMs by making tools as general-purpose as possible. Fewer, more capable tools consume less of the AI's context window than many narrow-purpose tools. We consolidate functionality (e.g. get_messages handles search, browse, read-by-ID, and replies in one tool; invoke_mtproto provides raw API access for edge cases), use uniform schemas across tools so responses can be automatically processed when possible, and keep descriptions concise. We accept more parameters per tool and slightly more complex signatures in exchange for fewer tools and less context. When adding capabilities, we prefer extending existing tools over introducing new ones.
