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

The annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds useful context by specifying that the feed is public and fresh, but it does not disclose pagination behavior, update cadence, or any other operational trait beyond that.

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, efficient sentence that front-loads the source and content type. Every word contributes to identifying the tool, with no filler or redundancy.

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 parameters, full annotation coverage for safety, and an output schema to describe the return payload, the description is nearly sufficient for correct invocation. The only meaningful gap is sibling differentiation, which keeps it from being fully complete.

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 no parameters, so the baseline for parameter semantics is 4. There is nothing for the description to clarify beyond the schema, and no parameter-related gaps exist.

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 identifies the source (Moneycontrol) and content type (fresh top stories from the public feed), so an agent knows what it returns. However, it does not explicitly distinguish this tool from close siblings like moneycontrol_headlines or moneycontrol_sections, so it falls short of a 5.

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 states what the tool provides but gives no guidance on when to use it versus alternatives such as moneycontrol_headlines or moneycontrol_article. There are no conditions, exclusions, or routing hints, leaving usage entirely to inference.

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