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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered structurally. The description adds no behavioral context beyond that: no note on authentication, on what happens when the identifier does not resolve, or on whether the open-world lookup hits an external OAI resolver.

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. It is appropriately sized for a one-parameter lookup tool, though the 'Compoid ID or OAI' clause is the only substantive content and could have carried one more clarifying detail at no real length cost.

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 described, and annotations cover the safety profile. What remains missing is behavior on a non-matching identifier and any hint that the identifier may come from an external (open-world) source, which matters for a lookup tool with 0% parameter documentation.

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 single parameter 'work_id' carries no title-level explanation, so the description must compensate. It does add meaningful semantics by stating the value may be a Compoid ID or an OAI identifier, but it never maps that onto the 'work_id' field name, leaving ambiguity about the accepted format.

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?

Specific verb+resource: 'Get detailed information about a specific record'. The 'by its Compoid ID or OAI' clause distinguishes it from the search_records and get_collection_records siblings, which return sets rather than one record. It stops short of naming those siblings explicitly, so it is clear but not fully differentiated.

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, no mention of prerequisites, and no routing to alternatives such as Compoid_search_records when the identifier is unknown. The agent must infer that this is the single-record lookup path purely from the word 'specific'.

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