get_model_profile

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

No annotations exist, so the description carries the full behavioral burden. 'Get' implies a read-only lookup and the parenthetical helpfully discloses the returned fields, which compensates somewhat for the absent output schema, but there is no disclosure of error behavior for an unknown model, caching, or whether results reflect the registry configured via set_model.

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?

A single front-loaded sentence with no filler, and the key element (the profile) leads. It is arguably too terse rather than bloated, which is captured elsewhere rather than being a conciseness defect.

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 one-parameter lookup with no annotations and no output schema, the description should at minimum pin down the model identifier format and failure behavior. It discloses the returned field groups, which is useful, but leaves the agent guessing about how to form a valid argument and what an unknown model yields.

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 0% for the single required 'model' parameter, and the description does not compensate: it never states the expected identifier format (bare model name vs provider-qualified string) or what happens when the value is not in the registry. The phrase 'from the registry' only weakly implies that 'model' is a registry key.

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?

States a specific verb and resource ('Get model profile') and enumerates what the profile contains (tier, capabilities, blunder patterns) plus its source (the registry). It does not distinguish itself from nearby siblings such as detect_model, model_decision, or get_guardrails, which an agent could easily confuse with it.

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?

No when-to-use guidance is given; nothing says to call this when you already know the model name versus using detect_model to discover it, nor how it relates to model_decision. The 'from the registry' phrase hints at a lookup versus detection, but the agent must infer it.

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