TDQS

A4.2/5.0

Behavior4/5

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

Annotations already cover readOnlyHint and openWorldHint, so safety is settled. The description adds genuine value by framing the tool as an enumeration of valid year values for a list, which an agent needs to know to use it as a lookup. Minor gap: no note on whether the year set varies by list or how stale coverage is.

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 return contract and the disambiguating routing hint. Nothing redundant, and the core value is front-loaded.

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?

An output schema exists, so return-shape explanation is not needed, and annotations cover the safety profile. The description is nearly complete for a one-param lookup, though it could note the relationship to fortune_ranking_lists to fully close the sibling ambiguity.

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% with one optional parameter, so the schema already documents the list values and default. The description only echoes the notion of a 'selected list' without adding format or defaulting detail beyond the schema. Baseline 3 is appropriate.

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?

States a specific verb and resource: returns every accepted year for a selected Fortune ranking list, with a concrete example (2023-2026 Fortune China 500). This is clearly distinguishable from siblings fortune_ranking, fortune_ranking_lists, and fortune_ranking_filters.

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

Usage Guidelines4/5

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

Explicitly routes the agent to fortune_ranking for searching a ranking, which is the main alternative. However it does not address when to use this versus fortune_ranking_lists or fortune_ranking_filters, so the guidance is clear but incomplete on the sibling boundary.

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