Removed deprecated *_tool() aliases: calculator_tool(), query_sql_tool(), read_file_tool(), write_file_tool(), fetch_url_tool(), plot_tool(), data_profile_tool(), and r_help_tool(). Use the tool_*() factories introduced in 0.1.0 instead. The old names have been warning since 0.1.0.
New features
guarded_tool(tool, input_guards, output_guards) — compose a securer_tool with input/output guardrails. Returns a drop-in securer_tool replacement that enforces the guardrails on every invocation and surfaces failures as tool-call errors.
