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

Annotations already establish a safe, non-open-world read, so the bar is lower. The description adds real value by disclosing the returned contents (download link, system requirements, dashboard link), which matters because there is no output schema; it does not indicate whether links are static or how the requirements are formatted.

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?

A single sentence with zero filler, front-loading the primary value (download link) before the secondary item (web dashboard). Nothing repeats the name or title verbatim.

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 zero-parameter, read-only lookup with no output schema, the description covers what the agent needs to know before calling. Minor incompleteness remains around how the returned links and requirements are structured, but for this complexity the definition is adequate.

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 and there is nothing to disambiguate. The description correctly implies a no-argument call by not referencing any inputs.

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?

Names the specific resource clearly: download link plus system requirements for the Ghostpilot macOS app and the web dashboard link. The retrieval verb is only implied, but the content is concrete enough to separate it from siblings like get_pricing or get_product_overview.

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?

Usage is only implied by topic (an agent asking about installing or downloading the app would pick this). There is no explicit when-to-use statement, no mention of overlap with get_product_overview, and no note that no arguments are needed.

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