TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare read-only, idempotent, non-destructive, closed-world behavior, so the description does not need to restate safety. It adds meaningful context beyond the annotations: the result is signed and dated, has 62 fields, and costs $2 USDC. It stops short of explaining payment mechanics or whether a failed call is still charged.

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

Conciseness4/5

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

The key purpose and sibling routing are front-loaded, and the cost notice earns its place. The phrasing is slightly compressed and the return-shape note ('62 fields including as_of, available') is less useful because an output schema already exists.

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

Completeness4/5

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

With an output schema, full schema description coverage, and rich annotations, the description supplies the missing high-value context: signed/dated output, sibling differentiation, and the $2 USDC cost. It is mostly complete, though payment and failure-charge behavior remain unstated.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents all six parameters. The description does not add parameter-level meaning beyond the schema; 'as_of' appears only as an example return field, not as an explanation of the input parameter.

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 states a specific verb and resource: 'Return ONE signed, dated strategy verdict.' It also explicitly distinguishes the tool from its closest sibling, `evaluate_portfolio_verdict`, so an agent can tell which verdict tool to choose without opening either schema.

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

Usage Guidelines5/5

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

It gives an explicit routing rule: use this rather than `evaluate_portfolio_verdict` for a strategy verdict, not a portfolio verdict. That is precisely the kind of when-to-use/when-not-to-use guidance needed among many similarly named verdict tools.

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