TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the description does not need to repeat those. It adds that the tool searches a directory of thousands of MCP servers and returns community and hosted servers, which is relevant behavioral context without contradiction.

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 sentences, each delivering core information: what the tool does and when to use it. No extraneous words, front-loaded with the action, and examples are embedded efficiently.

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

Completeness5/5

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

Given the output schema exists, return values are handled. The description covers purpose, scope, and usage context thoroughly, with high schema coverage and clear annotations. Nothing additional is needed for an agent to understand how and when to invoke this tool.

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

Parameters4/5

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

Schema description coverage is 100%, so baseline is 3. The description adds value by providing example values for the query parameter and clarifying it is by use case, enhancing understanding beyond the schema's basic descriptions.

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 clearly states the tool searches MCP servers by use case, with examples like 'database', 'email', 'calendar'. It distinguishes itself from siblings by noting it returns servers beyond Pipeworx, avoiding confusion with internal search tools like search_packs.

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?

The description specifies to use this tool when looking for tools beyond Pipeworx, providing clear context. While it doesn't explicitly list when not to use, the phrase 'beyond Pipeworx' implies it is for external servers, and sibling names suggest alternatives like search_packs are for internal tools.

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