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, but it is extremely thin. The line 'MARS remains intermediary only' gestures at MARS's neutral role, but its operational meaning is vague. Nothing is said about what 'review' involves, whether the submission is editable or retractable, what side effects occur, or what conditions must hold before submitting.

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 compact and front-loaded with the primary action in the first sentence. However, the second sentence, 'MARS remains intermediary only,' spends its words on a cryptic phrase that adds little actionable value. Brevity here comes at the cost of necessary detail, making it under-specification rather than disciplined conciseness.

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?

This is a 5-parameter tool with a nested object, no required parameters, no output schema, no annotations, and 0% schema coverage — yet the description provides only two short sentences. An agent has no way to know what data to populate, what the review flow is, what the response will contain, or how this relates to the precheck and offer tools. The definition is a bare stub relative to the tool's complexity.

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% and the description adds zero parameter-level information. The five parameters (subject, currency, owner_agent, requirement, jurisdiction) are entirely unexplained, including the nested 'requirement' object, which is likely the payload's core. The description 'Submit B2B demand' only weakly implies what subject/requirement might hold; the burden falls entirely on the agent to guess formats and semantics.

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 uses a specific verb and resource ('Submit B2B demand for review'), clearly identifying the operation's subject. The word 'demand' helps distinguish it from sibling tools like publish_offer, though it never names that sibling directly. The cryptic phrase 'MARS remains intermediary only' adds some ambiguity and keeps this from 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?

No guidance is given on when to use this tool versus the 14 siblings such as publish_offer, request_quote, or mars_deal_route_precheck. Usage is only implied (submit when you have B2B demand to review), with no conditions, exclusions, or alternative-selection criteria. For a tool in a crowded ecosystem, this is a significant gap.

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