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

Annotations already establish readOnly, idempotent, non-destructive and closed-world behavior, so the safety profile is covered. The description adds semantic meaning (option_id is opaque, name is the user-facing label, depends_on means conditional existence) but discloses nothing operational such as behavior for an unknown model identifier or what lang changes. Useful but modest value on top of structured data.

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?

It is a single compact sentence with no filler, so nothing is wasted. However it is a noun-phrase fragment with no stated subject or verb, which makes the first read ambiguous about whether the tool returns these things or accepts them as input.

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?

Because an output schema exists, the description need not restate return fields, yet it spends its whole length doing exactly that while saying nothing about the required 'model' argument's expected format or the effect of 'lang'. An agent can call it, but the input side and the routing among siblings remain underspecified.

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%, with a required 'model' string and a 'lang' enum that the description never mentions. The description only explains fields of the returned payload (option_id, name, exclusive_group, depends_on), which are not parameters of this tool, so it does not compensate for the documentation gap on the two inputs.

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 names the resource and its concrete parts: components, options with their fields, mutual exclusions (exclusive_group) and dependencies (depends_on). That is specific enough for an agent to know this tool returns the full configurable breakdown of one model. It never differentiates itself from siblings like list_models or quote_configuration, 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 when-to-use guidance, no prerequisite, and no mention of alternative tools such as list_models (to discover models) or quote_configuration (to price a selection). The agent must infer the usage context entirely from the name and sibling list.

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