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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the agent knows this is a safe, open-world read. The description adds that the sections are 'public', which is consistent but adds little beyond the annotations. It does not describe return structure, but an output schema exists.

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 fragment with no wasted words. It is front-loaded with the resource and scope, though the phrasing is slightly terse and could be marginally clearer.

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?

Given no parameters, an output schema, and annotations covering the safety profile, the description provides enough context: it names the resource, its public nature, and its relationship to moneycontrol_headlines. It does not need to explain return values because the output schema handles that.

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 the baseline is 4. There are no parameters to clarify, and the description does not need to compensate for any schema gaps.

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 states the tool returns Moneycontrol public editorial or RSS sections, and ties them to moneycontrol_headlines as the consumer. It distinguishes this tool from sibling tools (article, author, news) by focusing on sections. The purpose is clear, though the phrasing is slightly indirect by not using an explicit verb like 'list'.

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?

It explicitly says the sections are 'accepted by moneycontrol_headlines', which tells an agent to use this tool to obtain valid section identifiers for the headlines sibling. No when-not or alternative conditions are given, but the primary usage context is clear.

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