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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds one piece of behavioral context, that suggestions are returned alongside the evaluation, which goes beyond the annotations. It says nothing about behavior for unknown/incomplete evaluations or error conditions.

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 front-loaded sentence with no filler; 'and its suggestions' is the one clause that genuinely adds information. It is efficient, though brevity here edges toward under-specification rather than tight writing.

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?

This is a simple single-parameter read with full annotation coverage, so the bar is low. However, with no output schema, the description could have said more about what an evaluation result contains and whether suggestions are always present. It is adequate but leaves the return shape vague.

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?

There is a single parameter with 100% schema description coverage, so the schema already documents evaluation_id as 'Evaluation result ID.' The description adds no further meaning, such as where the ID comes from or its format. Baseline 3 applies when the schema does the heavy lifting.

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 has a clear verb ('Get') and resource ('an AI evaluation'), and it adds the useful detail that the response includes the evaluation's suggestions. It doesn't explicitly distinguish itself from siblings such as list_evaluation_results or evaluate_work_item, but the singular retrieval framing is understandable. What an 'AI evaluation' actually contains remains underspecified.

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 when-to-use guidance: nothing says to call this after evaluate_work_item, or to use list_evaluation_results when the ID is unknown. The agent must infer the workflow and the ID source entirely. The only implicit cue is the required evaluation_id parameter.

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