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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'real-time updates' and 'official company press releases,' but does not disclose return format, pagination behavior, date-range handling, or whether results are global or company-specific. This is insufficient for a tool with no output schema and no annotation support.

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 two sentences and front-loads the core purpose. The phrase 'with the FMP Press Releases API' is somewhat redundant given the tool name, but it does not add meaningful clutter. Overall, it is concise and efficiently structured.

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 output schema and no annotations, the description should provide enough context about what the call returns and how results are scoped. It does not clarify whether this returns all press releases globally or supports a specific company, especially since the schema lacks a ticker/symbol parameter and the sibling list includes searchPressReleases. This ambiguity is a significant 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?

The input schema covers all four parameters (to, from, page, limit) with descriptions, so the baseline is 3. The description adds no parameter-specific meaning, but it is not required because the schema already documents each parameter fully.

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 uses a specific verb ('Access') and a clear resource ('official company press releases'), then details content types ('corporate announcements, earnings reports, mergers'). This clearly distinguishes it from sibling searchPressReleases, which implies a search behavior, while this tool is the direct access/feed variant.

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 usage for retrieving press releases but gives no explicit when-to-use or when-not-to-use guidance. It does not mention alternatives like searchPressReleases or related news tools, so an agent gets only implicit context.

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