Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety is covered. The description still adds value by disclosing what content the response contains (difficulty, paper requirements, materials, lesson links), which tells the agent what to expect beyond the output schema's shape.
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 sentence, zero filler, with the returned content front-loaded ahead of the input key. Nothing could be removed without losing information.
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?
With one fully documented required parameter and an output schema, the description needs only to state what comes back and how to key in, which it does. The only gap is not clarifying how ambiguity in a name is resolved or why find_origami might be preferred for name-based lookups.
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 coverage is 100% and the single parameter already documents 'Public model slug, identifier or unambiguous model name.' The description restates the same accepted key forms without adding format hints such as case sensitivity or slug normalization rules, so baseline 3 applies.
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 (returns) plus resource (a model summary) with the exact fields enumerated: difficulty, paper requirements, materials, and lesson links. That distinguishes it adequately from get_origami_steps (steps) and suggest_origami, but it never names a sibling explicitly, so the separation is inferred rather than stated.
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 lookup key is stated ('for a slug, identifier or unambiguous name'), which implies usage, but there is no explicit when-to-use/when-not guidance and no mention of find_origami as the alternative for name-based discovery. The agent must infer the routing itself.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
