TDQS

B3.2/5.0

Behavior3/5

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

Annotations already establish readOnly=true, idempotent=true, destructive=false, and a closed-world scope, so the safety profile is fully covered. The description only adds that the tool both scores and surfaces the weakest dimension, without stating score aggregation, weighting, or what happens with optional currency omitted.

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?

One front-loaded sentence delivers the verb, dimensions, scale, and key output with no padding. The trailing URL is mildly promotional and adds no invocation value, costing a point.

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

Completeness3/5

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 described, and annotations cover the safety profile. The remaining gap is usage context — for a tool sitting among ~100 calculation siblings, the description never says when this one is the right pick.

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 each parameter is already documented with its 1-4 anchor scale. The description's list of dimensions ('systems, attribution, governance, forecasting, automation') loosely maps to the five required params but adds no syntax, defaults, or edge-case behavior beyond the schema.

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

Purpose4/5

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

The description states a specific verb ('Score') and resource ('RevOps maturity'), enumerates the five dimensions, and specifies the 1-4 scale plus the derived output ('identify the weakest area'). It does not, however, differentiate itself from the closest siblings (e.g. gtm_audit_scorecard), so it falls short of a 5.

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

Usage Guidelines2/5

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

There is no guidance about when to use this tool versus the many sibling graders/scorecards, no prerequisites, and no exclusions. The reader must infer applicability from the dimension names alone.

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