WHY IT NEEDS A POLICY

Why index_repository needs a policy

The tool name 'index_repository' strongly implies it creates or populates an index — a Write operation — by ingesting and storing code data into vector and graph databases. Sibling tools like 'cancel_indexing_job' and 'clear_index' reinforce that indexing is a meaningful, stateful write operation on this server.

From the tool's definition Tool name 'index_repository' on a server that performs 'real-time indexing' of repositories with 'AST-aware chunking and relationship tracking' via 'vector and graph databases'.
