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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context: it returns Markdown, includes the source URL, and explicitly states it does not sign in or mutate the platform. This goes beyond the annotations and helps the agent understand side effects and output format.

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 with no wasted words. It front-loads the core action and resource, then adds the key behavioral details. Every sentence earns its place.

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 enum-constrained parameter and no output schema, the description is nearly complete. It covers what is returned (Markdown, source URL) and what side effects do not occur. The only minor gap is that it does not describe the structure of the Markdown content or any pagination, but that is not critical for a single-page read 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%, so the description must compensate. The description explains that the 'path' parameter selects a public Floatout guide page, and the enum in the schema lists valid paths. The description adds meaning by clarifying that the path refers to a guide page and that the output is Markdown. However, it does not explain the path format or how to choose a path beyond the enum, so a 4 is appropriate.

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 a specific verb ('Read'), a specific resource ('public Floatout product, pricing, security or operator guide'), and the output format ('as Markdown'). It also distinguishes itself from siblings by noting it returns current published content with its source URL and does not sign in or change the platform. This is clear and specific.

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 when to use this tool: when you need to read a public Floatout guide page. It also explicitly says what it does not do ('Does not sign in or change a platform'), which helps rule out alternatives. However, it does not explicitly name sibling tools or state when to use them instead, so it falls short of a 5.

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