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

The readOnlyHint annotation already establishes that this is a safe read operation. The description adds the concrete REST endpoint, which reinforces the hierarchical lookup path, but it does not explain error behavior, missing IDs, or response shape.

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 description is brief and front-loaded with the action and resource. The appended REST endpoint is useful for developers, though the 'Sorry:' prefix is slightly noisy.

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?

For a low-complexity single-item read with three required, fully documented parameters and a readOnlyHint, the description is sufficient. It does not describe the returned update object, but this is a minor gap given the tool’s simplicity.

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 100%, so page_id, notice_id, and update_id are already documented in the input schema. The description’s endpoint path echoes those parameters but adds no additional format or semantic detail beyond the schema.

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 states a specific verb-plus-resource: get one update of a notice. It clearly distinguishes fetching a single update from listing or creating updates, though it does not explicitly name those sibling alternatives.

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?

There is no explicit guidance on when to use this tool versus sorryapp_list_notice_updates or sorryapp_get_notice. The purpose implies a single-item read, but the description supplies no conditions, exclusions, or alternatives.

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