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

Annotations already declare readOnly, idempotent, and non-destructive behavior, so the safety profile is covered. The description adds that results include both attributed views and Headge-mapped related views, but it does not explain what 'Headge's mapping' means or disclose pagination/limit behaviors.

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 with no filler. However, 'Headge's mapping' is unexplained and the sentence is a noun phrase rather than a clear action-oriented statement.

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 simple read-only tool with one parameter and an output schema, the definition is mostly adequate. The unexplained proprietary terminology and lack of sibling differentiation leave enough ambiguity that an agent may not fully understand the result set or when to call this tool.

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?

Schema description coverage is 0%, but the description ties the sole parameter to the ticker being queried via 'this ticker', giving it practical meaning. It leaves format and notation unspecified, but for a single string parameter this is mostly sufficient.

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 that the tool returns attributed views naming the given ticker, plus related views labelled as Headge's mapping. This conveys the resource and scope clearly, although it lacks an explicit verb and does not contrast with siblings like get_view.

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?

There is no guidance on when to use this tool versus alternatives such as get_view or search. The only implicit context is the ticker parameter, which is not enough to route an agent confidently.

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