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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds that output is parsed and paginated, which is useful context, but it does not explain cursor behavior, truncation at max_characters, or what a partial result looks like.

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?

One front-loaded sentence with no filler, and scope is stated before the pagination attribute. It is efficient, though arguably too terse for a four-parameter tool with undocumented semantics.

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?

An output schema exists, so return values need not be re-explained, and annotations cover the safety profile. Still, the mechanics most likely to cause a mis-call — cursor continuation and max_characters truncation — are absent, which is a meaningful gap for a paginated text 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 carries the full burden, yet it only hints at pagination. It says nothing about the meaning of 'section', how 'cursor' is obtained or reused, or that max_characters (default 20000) truncates the text.

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 (Return) and resource (model-deviation text) scoped to 'one FAR part', which differentiates it from list_rfo_parts and get_rfo_agency_deviation. The only gap is that 'model-deviation text' is jargon an agent may not fully map to the domain.

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 single-part scope implies when it applies versus the list tools, but the description never names an alternative or states a condition for choosing get_rfo_part over get_rfo_guidance or get_rfo_agency_deviation. Usage is left to inference.

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