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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered without the description. The description adds the data provenance ('proxy statement') and the 'latest year' scoping plus a not-investment-advice disclaimer, but says nothing about coverage limits, lag, or what happens when a company has no proxy filing.

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?

It is a single front-loaded sentence with no filler, but a large share of it enumerates return fields that the output schema already defines, so much of the text does not earn its place. The trailing disclaimer is short and defensible.

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 an output schema present, the description need not explain return values — yet that is most of what it does. For a simple two-parameter read tool the coverage is adequate, but the absence of any selection guidance against the many sibling company/financial tools leaves a real gap.

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 100%, so both parameters (ticker, years) are already documented, and the baseline is 3. The description's mention of 'the latest year' and 'the CEO's pay history' gives indirect context for the years parameter but never explains its range or default, adding little beyond the schema.

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 names a specific resource — executive compensation as reported in the company's proxy statement — and enumerates the components (named-executive salary/bonus/stock/options/total, CEO pay plus YoY change and stock share, CEO history). That is distinguishable from general siblings like get_company_financials. It lacks an explicit verb (e.g. 'Returns'), so it reads as a content list rather than an action statement.

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, no mention of get_company_brief or get_company_financials as complements, and no stated prerequisites such as which companies file proxy statements or how far back data goes. The only usage-adjacent line is the liability disclaimer 'Data, not investment advice.'

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