TDQS

B3.3/5.0
Behavior3/5

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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is supplied. The description adds useful replacement semantics for search_filters, but it does not explain whether the changes object is a partial update, what happens to omitted fields, or what permissions or side effects are involved. It does not contradict the annotations.

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?

It is a single front-loaded sentence with no redundant or filler wording. The compact slash structure communicates the field groups efficiently.

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?

The tool is complex, with a nested search_filters object and destructive update behavior, while the schema description coverage is only 33%. The description covers the main change categories and replacement semantics, but it does not explain partial updates, omitted-field behavior, or the full nested filter structure. Annotations and schema carry significant burden, making it marginally adequate rather than complete.

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 low at 33%, so the description should compensate, and it partially does by naming the main updatable groups: name, description, status, color, and search_filters. However, it omits status_label and does not explain partial-update behavior or the many nested search filter fields, leaving meaningful gaps 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 uses specific verbs (rename, edit, replace) and names the resource (list) plus the updatable field groups. It clearly distinguishes updating list metadata from sibling tools such as create_list, delete_list, and get_list, though it does not explicitly name alternatives.

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 explicit when-to-use guidance, no when-not-to-use guidance, and no routing to alternatives like update_status or delete_list. The phrase 'Rename a list' implies usage, but the agent is left to infer when this tool is appropriate versus recreating or deleting a list.

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