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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description reinforces that this does not complete acknowledgements, which is useful but mostly restates the read-only nature rather than adding details such as scope, permissions, or return behavior.

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?

It is a single compact sentence with the core action front-loaded and no wasted wording. It could still afford one clause distinguishing it from the acknowledgement summary/overview siblings.

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 tool is simple, annotations are rich, and an output schema exists, so much of the context is covered. However, with many similarly named acknowledgement-related siblings, the description leaves an important routing gap about when this specific tracking read is appropriate.

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%, and the description does not explain documentType or documentId at all. The schema's enum and pattern give some constraints, but the description does not compensate for the missing semantic guidance needed to choose values correctly.

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 clear verb and resource: reading acknowledgement tracking for a document. It distinguishes itself from an acknowledgement-completion action, but does not distinguish itself from sibling tools such as get_acknowledgement_summary or get_acknowledgment_overview.

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 provides only a negative usage hint ('does not complete acknowledgements'). It gives no guidance on when to use this tracking read versus the many acknowledgement summary/overview/list siblings.

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