TDQS

A4.3/5.0

Behavior4/5

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

Annotations already cover non-destructiveness and read-only status. The description adds meaningful behavioral context beyond that: the decision has a 15-minute expiry, includes evidence-coverage confidence, risk flags, and invalidation conditions. This tells the agent the result is time-sensitive and conditional, useful context the annotations do not convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences. The first front-loads the decision output and key metadata; the second enumerates the combined inputs. There is no filler or repetition of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given there are no parameters and an output schema is present, the description only needs to convey what the tool decides and what it covers. It names the decision categories, confidence component, risk flags, invalidation conditions, expiry, and the combined market inputs, so an agent can select it appropriately.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters and the input schema is an empty object, so there is no parameter information for the description to add. The description does not need to compensate for schema gaps because there are no parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Return ENTER_RISK, WAIT or REDUCE_RISK with score, evidence-coverage confidence, reasons...' This clearly defines the tool's output and decision categories. It also differentiates itself from data-focused siblings like market_data and market_history by stating it combines regime, gas, APY, spot prices, perps, and seven-day history into one decision pack.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit when-to-use/when-not-to-use guidance or named alternatives. The phrase 'One call combines...' implies the tool is intended as an all-in-one decision substitute for multiple data calls, but this is left to inference rather than stated directly.

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