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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the bar is lower. The description still adds useful context beyond them: it returns Markdown, includes the source URL, and reflects 'current published content' rather than cached/stale data.

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?

Three short sentences with no filler: purpose first, return value second, scope boundary third. Every sentence earns its place and nothing important is buried.

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 full annotation coverage and no output schema, the definition covers purpose, return format, and safety scope adequately. The one gap is that the meaning of the 'path' enum values is never described, though the enum is largely self-explanatory.

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% and there is one required parameter, so the description carries some burden. It gestures at what kinds of pages exist ('product, pricing, security or operator guide'), but never explains that 'path' selects one of the enumerated site routes, leaving the agent to infer it from the enum alone.

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?

States a specific verb ('Read') and resource ('public Floatout product, pricing, security or operator guide') plus the output format (Markdown). It does not explicitly distinguish itself from the sibling read_builder_fee_study, but the scope of public guide pages is reasonably implied by the enum-constrained path.

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?

'Read a public ... guide' and 'Does not sign in or change a platform' imply the appropriate context (read-only lookup of published docs). However, no alternative is named (e.g. when to prefer read_builder_fee_study over a guide page) and there are no explicit exclusions.

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