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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description need not restate these. The description adds value by listing specific content areas (e.g., mission, pillars) and mentions 'article count' which suggests return of statistical data, but does not detail response format or potential limitations.

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, concise sentence that is front-loaded with the main purpose ('Get an overview') and then lists specific items. Every word adds value without fluff.

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?

For a zero-parameter read-only tool with a clear purpose, the description is sufficient. It does not explain return format, but the presence of an output schema likely covers that. The inclusion of 'article count' hints at quantitative output, but no further details are needed for an agent to invoke it successfully.

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?

Since the tool has zero parameters, the schema provides no parameter documentation. The description compensates by listing exactly what information will be returned (mission, pillars, audience, sponsorship, article count), giving the agent a clear expectation of the output.

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 clearly states the tool provides an overview of The Revenue AI Report, listing specific aspects like mission, editorial pillars, audience, sponsorship policy, and article count. However, it does not explicitly differentiate from 'get_publication' which may have overlapping functionality.

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?

The description implies the tool is used to get high-level information about the publication, but it does not specify when to use this instead of 'get_publication' or other siblings. There is no mention of alternatives or exclusions.

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