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

Annotations indicate idempotent and destructive behavior, but the description fails to explain what is destroyed (e.g., are previous settings overwritten irreversibly?) or the scope of the update (partial vs full replacement).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely brief at four words, which prevents redundancy, but front-loads so little information that it borders on under-specification rather than efficient conciseness.

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

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

Inadequate for a destructive, idempotent operation with 10 parameters. Lacks explanation of side effects, return values, error conditions, or the relationship between parameters like templates and pagination settings.

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

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

With 100% schema description coverage, the schema adequately documents each parameter. The description adds minimal semantic value beyond grouping parameters as 'settings', meeting the baseline expectation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States the action (update) and resource (collection settings), but is vague about what constitutes 'settings' and does not differentiate from sibling tools like update_content or update_template.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides no guidance on when to use this tool versus alternatives (e.g., update_content for items within a collection), nor mentions prerequisites or constraints beyond the ID requirement.

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