get_model

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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety and idempotency profile is covered. The description adds the useful fact that this is the "full card" surface (as opposed to a summary), but says nothing about failure behavior for an unknown ID, URL-vs-ID resolution, or rate limits. The trailing "Returns: The model details." line is vacuous rather than informative.

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 opening sentence is dense and well front-loaded with real content. However, the "Returns: The model details." stanza is pure filler that repeats the first sentence's premise and occupies roughly a third of the 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?

With an output schema present and full schema coverage on the one parameter, the description only needs to characterize scope, which it does by naming the card's constituent parts. It is nearly complete; the main omission is any hint about behavior when the supplied ID or URL does not resolve.

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% and the single "model" parameter is already documented as an ID ("3161") or model page URL. The description adds no additional meaning about the parameter, so the 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?

The description gives a specific verb and resource ("Get a model's full card") and enumerates the payload it returns: description, tags, category, license, print parameters, images, remixes. That enumeration implicitly separates it from list-oriented siblings like search_models and list_model_files, but no sibling is named explicitly, so it stops short of a 5.

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 statement of when to call this versus search_models, list_author_models, or list_model_files, and no note on prerequisites such as needing a valid ID first. The only implied usage comes from the schema's single required "model" parameter; the description text itself offers no routing guidance.

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