strip tool chatter from system prompts — the framework surfaces docstrings
operational instructions and the exploration system prompt both had
redundant listings of what specific tools do and when to use them —
content already present in each tool's docstring, which pydantic-ai
injects into the tool definition on every run. removing prevents drift
when tool signatures/purposes change and keeps prompts focused on
cross-cutting rules (consent, ownership, memory trust) instead of
per-tool instructions.
