Gbp.Location.Update

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

With no annotations, the description carries the full burden, and it does disclose one genuinely non-obvious behavior: the operation is guarded by a preview + confirm token handshake. However, it omits what the preview returns, how the token is obtained or how long it lives, whether the update is additive or a full replace, and what permissions are required for a mutation.

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?

One tight sentence with the guard behavior front-loaded in parentheses; nothing is wasted. It is arguably too terse for the amount of undocumented behavior, but that is a completeness problem rather than a structure problem.

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?

An output schema exists, so return values need not be explained, but for a 3-parameter mutation with 0% schema coverage and no annotations the description leaves the critical call path (how to get the confirm token) and the entire shape of 'fields' unspecified.

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 0%, so the description must compensate and largely does not. It maps location_name (resource name) and confirm (token) implicitly, but says nothing about the 'fields' object — which accepts arbitrary properties with additionalProperties=true — so the agent has no idea which field names are valid or whether this is an update mask or a merge.

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?

States a specific verb (update) and resource (a GBP location's fields) plus the addressing scheme (by resource name). This is enough to distinguish it from gbp.location.get and gbp.locations.list, though it never names those siblings explicitly.

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 parenthetical hints at a two-step guarded flow but gives no conditions for when to use this tool over gbp.location.get, no prerequisites, and no instruction on which call produces the preview versus consumes the token.

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