Built-in tools

Every bolt ships the same built-in tools. They are always available to the agent loop and cannot be shadowed.

The toolset

• describe_workspace — describes the workspace: collections, relations, and permissions
• read_collection — reads records, applying the subject’s policy grants row by row
• write_collection — writes records, only where the policy grants create/update/delete (with field masks and approvals)
• list_skills — lists available skills, and read_skill loads one skill’s contents
• spawn_subagent — spawns a subagent for a narrower task

Reserved

These names cannot be reused by custom tools — the compiler rejects a redefinition.
