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

Annotations already declare readOnlyHint=true, so the safety profile is covered structurally. The description adds nothing on top of that: no behavior for a nonexistent or archived id, no note on whether archived terms are returned, no sense of payload size. With annotations doing the only work, the description contributes zero behavioral context.

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?

The single sentence is free of padding, but it is not concise so much as empty — it conveys nothing an agent could not read off the tool name. A terse sentence that earns no place is under-specification, not conciseness.

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 the simplest possible tool shape: one required string id, full schema coverage, and a readOnly annotation. That alone makes it callable. However, with no output schema, the description should have said something about what comes back or what happens when the id is not found, so it is only minimally viable.

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 100% for the single required parameter, so the baseline of 3 applies. "Id of the Dictionary term." in the schema is as informative as the description is, and the description supplies no format hints (UUID vs slug) or examples. No penalty, but no added value either.

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?

"Get one dictionary term" restates the tool name and title almost verbatim, giving no information beyond the identifier. It never distinguishes this from siblings like list_dictionary_terms, get_idea, or get_project, nor does it say what a 'dictionary term' contains. This is the tautology case the rubric reserves a 2 for.

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 at all: nothing says when to call this versus list_dictionary_terms (to enumerate) or update_dictionary_term (to modify). The closest thing to guidance is the word "one", which weakly implies single-item retrieval, but no alternative or condition is named. Not misleading, just absent.

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