Get Model Profile

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that it returns a profile, but does not explain side effects (likely none), performance characteristics, whether it errors if the identifier is not found, or the semantics of 'validated' and 'local registry'. This is insufficient for a tool with no annotation support.

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 description is extremely concise (one sentence), but conciseness is not the same as adequacy. It is not front-loaded; it is just a minimal phrase that could be a tautology. It is not padded with fluff, but it is under-specified, which is a different issue. A score of 3 is generous because it is at least short.

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?

Although the tool has only one parameter and an output schema, the description fails to clarify the tool's role in the larger migration workflow. Given the sibling names, this tool likely serves a specific function in model profiling, but the description does not explain what 'validated' or 'local registry' mean, nor how it relates to other tools. The output schema might help, but it is not visible to the agent without additional context.

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?

The schema coverage is 0% and the description does not explain the 'identifier' parameter beyond the schema's type. It does not mention that the identifier likely refers to a model name or ID, or how it should be formatted. With a single parameter, the description should at least clarify what the parameter represents, but it adds no value.

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 is minimal: 'Return a validated local registry model profile.' It specifies a verb ('Return') and a vague resource ('model profile'), but it does not define what 'validated' or 'local registry' means, nor does it distinguish from siblings like 'resolve_model' or 'compare_models'. It merely restates the tool name without useful detail.

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 offers no guidance on when to use this tool versus alternatives such as 'resolve_model' or 'check_model_lifecycle'. It does not mention any context, prerequisites, or exclusions. An agent would have no idea whether to call this or a sibling for a given task.

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