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

With no annotations, the description carries the full behavioral burden. It implies a reference/read-only lookup by listing static facts, but never states that the call has no side effects, requires no authentication, or returns cached/static 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?

A single compact sentence that front-loads the content domains with no filler. It loses a point for lacking a verb and for the undefined phrase 'the three commercial routes,' which reads as shorthand the agent cannot act on.

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?

There is no output schema and no annotations, so the description is the only source of truth about what comes back, yet it offers only a bare noun list with no structure or detail. For a zero-parameter facts endpoint, that leaves the agent unsure what payload to expect.

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 tool takes zero parameters, so there is no parameter semantics to document and the baseline of 4 applies. Nothing in the description misrepresents the empty input schema.

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 enumerates the content domains (production, fabric, lead-time, payment, shipping, three commercial routes) but never states a verb or retrieval action, so the agent must infer 'fetch reference facts' from the name alone. It also does not distinguish itself from overlapping siblings like get_buying_options, get_routes, or get_price_list.

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 at all, despite several siblings (get_routes, get_buying_options, get_price_list) that appear to cover adjacent territory. The agent has no signal about when this tool is preferable to those alternatives.

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