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

Annotations already declare readOnly/destructive/openWorld, so the safety profile is covered. The description adds substantial context beyond that: IsEnabled defaults to DISABLED for a documented reason, MaxSendsPerTitlePerDay is the only ceiling on a broadcast, quiet hours operate in the subscription's locale and may cross midnight. It omits operational behavior such as error or auth handling, so not a 5.

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?

The definition is front-loaded with the purpose, but at roughly 170 words for a one-parameter read tool it is heavily padded. Sentences about VAPID keys and the PushEndpoints/PushBindings collections are tangential background that does not help an agent invoke this tool.

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?

With no output schema, the description usefully enumerates the returned fields (IsEnabled, MaxSendsPerUserPerDay, MaxSendsPerTitlePerDay, QuietHoursStart/End, mobile secret names) so the agent can interpret the response. It stops short of any field format or response-envelope detail.

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 coverage is 100% for the single title_id parameter, so the schema already documents it. The description adds no syntax, format, or scoping detail for title_id beyond what the schema provides, making 3 the correct baseline.

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 and resource with an explicit scope: 'GET ONLY the Push field of TitlePublicConfigurationModel.' The opening line lets an agent distinguish this from the broader get_title_data and from the write counterpart save_push without opening a schema.

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 'GET ONLY' framing and the note about what is excluded (VAPID keys, subscriptions) imply scope, so usage is inferable. But there is no explicit when-to-use or when-to-use-something-else guidance naming get_title_data or save_push as alternatives, which is exactly the comparison an agent needs.

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