TDQS

A3.5/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is fully covered. The description adds useful context about the returned fields, but with an output schema present that is largely redundant, and it says nothing about pagination or how limit interacts with large folders.

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?

Three short sentences with the core operation front-loaded and no filler. It could be tightened slightly by folding the return-field list into the purpose sentence, but nothing is wasted.

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 rich annotations, a full output schema, and 100% schema parameter coverage, the remaining burden on the description is light and it meets it: what the tool does and when to reach for it are both covered. Only sibling routing and pagination behavior are missing.

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 both parameters (path with root-folder convention, limit with default) are documented in-schema. The description adds no syntax or format meaning beyond what the schema already provides, so the baseline 3 applies.

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 (list files/folders in a Dropbox directory) that is unambiguous. However, it never distinguishes itself from close siblings like dropbox_search or dropbox_get_metadata, which an agent browsing the tool list would need help choosing between.

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?

"Use when browsing folder contents or checking what's stored at a path" gives implied usage, which is adequate context. It stops short of naming alternatives (e.g., dropbox_search for name-based lookup) or stating when not to use this tool.

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