update_customer_geographic_access_scope

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the annotations, the description discloses that the operation atomically replaces the existing scope, is idempotent for identical requests, and carries specific auth/permission requirements. This adds meaningful behavioral detail about mutation, replacement, and safety that annotations alone do not convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Four dense sentences with no filler. The main action and scope are front-loaded, followed by constraints, idempotency, and permission requirements. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the key behavioral aspects: atomic replacement, hierarchy constraints, idempotency, and permissions. With no output schema, return behavior is not addressed, and parameter-level detail for X-Tenant-Id is thin, so it is not fully complete but is strong for a destructive update tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 33%, and the description partially compensates by explaining that the targetCustomerId must be the root or a child customer and that the authenticated tenant must be the hierarchy root. However, it does not explicitly explain X-Tenant-Id or customerContext semantics, leaving some parameter meaning to inference.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb and resource: 'Atomically replaces the geographic scope for a target customer' within a customer hierarchy. It is clearly distinct from sibling tools like update_user_geographic_access_scope and update_geographic_access_custom_region, which target different entities.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives clear eligibility context: the authenticated tenant must be the hierarchy root, the target must be the root or a child customer, and the UsersManager permission is required. It does not explicitly name alternatives or say when not to use this tool, but the context is strong enough.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
