TDQS

A3.6/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description still adds real value by warning that content is truncated, which is a behavioral trait not visible in any structured field. It stops short of explaining truncation limits or how to retrieve untruncated content.

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?

One sentence, zero waste, with the operation and the returned fields front-loaded. Nothing could be removed without losing information.

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?

With an output schema present, return-value detail need not be repeated, and the description correctly confines itself to operation and payload characteristics including truncation. The one gap is the absence of any routing or prerequisite context, which is minor for such a narrow lookup tool.

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?

There is a single parameter with 100% schema description coverage, including the filename format cue and the discovery hint, so the schema does the heavy lifting. The description only restates 'by filename' without adding syntax or resolution details, matching the baseline 3 for fully documented schemas.

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?

States a specific verb and resource ('Returns a knowledge-base entry by filename') plus the payload ('tags, metadata and (truncated) content'), so the agent knows exactly what comes back. It does not explicitly name the counterpart sibling (exim__kb__list), but the get-vs-list distinction is unambiguous from the phrasing.

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?

The description offers no when-to-use or prerequisite guidance; it only says what it returns. The only routing hint ('Discover via `kb list`') lives in the schema's parameter description, not in the tool description itself, so the description text carries no usage instructions.

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