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

The annotations already declare readOnly, idempotent, closed-world and non-destructive, so the safety profile is covered. The description contributes two real facts beyond them: only published records are returned, and the ID must be a versioned search result ID (not an arbitrary identifier). It still says nothing about what happens for unpublished or stale IDs, so the addition is useful but modest.

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?

A single front-loaded sentence with no filler and no repetition of schema or annotation content. Its brevity borders on under-specification rather than wasteful verbosity.

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, and the tool is simple with one required parameter. What remains missing is the relationship to the similarly shaped get_paper/get_patent/get_trial tools and the meaning of 'Blossom record', which an agent needs in order to pick this tool confidently.

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 schema documents only type and length constraints for 'id' and nothing about its provenance or format. The description partially compensates by defining the ID as a versioned search result ID, which is exactly the missing semantic, but it does not explain how to obtain one or what a version suffix looks like.

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 gives a specific verb and resource ('Fetch one published Blossom record'), which is more than a restatement of the name. However, 'Blossom record' is undefined and the sibling set contains get_paper, get_patent and get_trial that also retrieve single published entities, so an agent cannot tell from this sentence which one to call.

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 when-to-use or when-not-to-use guidance, and no mention of alternatives such as get_paper or get_trial. The phrase 'by a versioned search result ID' only implies the tool is used on IDs returned by a search, leaving the choice between this and the get_* siblings to inference.

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