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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is clear. The description adds that the tool returns user-specific data ('your classifiers... your plan... weekly decisions'), which is useful scope context beyond annotations. However, it does not disclose authentication requirements, rate limits, or return format details.

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?

The description is a single sentence fragment that is not front-loaded with a clear action. While short, it is under-specified and leaves the core purpose ambiguous, rather than being concise and informative.

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?

With no output schema, the description should clearly explain what the tool returns. It hints at classifiers, plan, limit, and weekly decisions, but the phrasing is vague and does not provide a usable return-value overview for an agent.

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?

The tool takes zero parameters, so there is nothing for the description to clarify. Schema description coverage is 100% and no parameters exist, meeting the baseline score of 4.

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?

The description is a fragment that names resources ('your classifiers', 'your plan', 'classifier limit', 'weekly decisions') without a clear verb like 'list' or 'retrieve'. It does not distinguish the tool from siblings such as get_decide_classifier or decide_create_classifier.

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?

No guidance on when to use this tool versus alternatives is provided. There is no indication of prerequisites, context, or exclusions.

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