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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile needs no restating. The description adds a little context about the nature of the payload (commercial terms plus a human confirmation step) but says nothing about freshness, sourcing, or whether the offer is static or generated per request.

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 short, but shortness here reflects under-specification rather than economy: a single fragment with no verb and no front-loaded statement of what is returned. It reads like a field list lifted from a spec rather than a usable definition.

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 no parameters, no output schema and rich annotations, the burden is light, and the content list gives a rough sense of the returned material. Still, the agent is not told the shape or stability of the offer, nor how the 'named person confirms the brief' step relates to start_order, leaving the tool's role in the workflow 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?

The tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. Nothing in the description misleads about 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 lists the topics the tool exposes (scope, fixed prices, delivery, payment, confirmation of the brief), which is more informative than the bare name get_offer, but it is an elliptical noun phrase with no verb such as 'returns' or 'retrieves'. It also gives no basis for distinguishing this from siblings like get_brand, get_market, or get_methodology, so the agent must guess at the boundary.

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 at all: nothing says whether this should be called before start_order, alongside get_brand, or only after a market is selected. The only implicit hint is the content list, leaving the sequencing decision entirely to inference.

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