TDQS

A3.7/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered without the description. The description adds the domain framing and the fact that scoring spans five weighted dimensions, but says nothing about how the score is computed or bounded beyond what the schema already states.

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?

Front-loaded single sentence covering verb, resource, and dimensions, followed by a short link. Efficient, though the promotional URL is slightly expendable rather than strictly earning its place.

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 values need not be explained, and annotations cover the safety profile. For a 6-parameter, fully documented scoring tool the description is sufficient, with only minor gaps in explaining the weighting outcome.

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%, and each parameter documents its ready/partial/no enum and weight, so the schema carries the semantic load. The description's list of dimensions mirrors the parameters but adds no format or interpretation detail beyond them — the baseline 3 applies.

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 (grade) and a specific resource (risk of pivoting upmarket to enterprise), and enumerates the five dimensions scored, which map directly to the required parameters. An agent can distinguish this from the many other '*_grader' siblings because the pivot-upmarket framing is unique.

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?

The description implies the usage context (assessing an upmarket/enterprise pivot) but gives no explicit when-to-use, prerequisites, or alternatives among the many adjacent graders (e.g. product_market_fit_scoring_grader, gtm_audit_scorecard). Usage is inferable but not guided.

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