get_record

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

Without annotations, the description must stand alone. It indicates a read operation via 'Fetch' and provides usage tips, but it does not disclose behavior for record-not-found, permissions, or potential errors. The guidance on select/expand adds some transparency, but not comprehensive.

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?

Two sentences, direct, with the core purpose front-loaded and parameter guidance in a second sentence. No extraneous text.

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 simple fetch-by-ID tool with a fully described input schema, the description sufficiently conveys what the tool does and how to shape results. It doesn't mention return format but the purpose implies it.

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 descriptions cover all 4 parameters with examples, so the description adds little beyond repeating the existence of select and expand. Baseline 3 is appropriate.

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 uses the specific verb 'Fetch' and identifies the resource as 'a single Dataverse record' with a GUID, clearly distinguishing it from sibling tools like query_records which fetch multiple records.

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 implies usage when you have a record GUID and need one record, and it offers guidance on select/expand for shaping output. However, it does not explicitly state when to prefer this over query_records or other alternatives, so it stops short of a 5.

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