TDQS

A3.8/5.0
Behavior3/5

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

Discloses return behavior but lacks details on side effects, edge cases, or whether it makes network calls.

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?

Extremely concise with no wasted words; front-loaded with action and return behavior.

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?

Covers essential aspects for a simple validation tool, but could mention validation strictness or supported mermaid version.

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?

Indicates the 'text' parameter should be a mermaid diagram string, adding meaning beyond the schema, but lacks specifics on format or length.

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?

Clearly states the tool validates a mermaid diagram text and specifies return values for both valid and invalid cases.

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?

No explicit guidance on when to use this tool vs alternatives, but implied usage is straightforward given no siblings.

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

A3.8/5.0
Disambiguation5/5

Only one tool exists, so there is no ambiguity whatsoever.

Naming Consistency5/5

With a single tool, naming is trivially consistent.

Tool Count3/5

A single tool for validation is borderline; it feels thin for a server named 'Inspector' but could be acceptable for a focused utility.

Completeness2/5

Only validation is provided; lacking features like parsing, rendering, or transformation for a diagram inspector.
