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

Annotations already declare readOnlyHint and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful, non-annotated context: an owner key is required and must be retrieved from the app's My Nation tab. It does not discuss response size, pagination, or how 'since' affects the payload.

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, each carrying distinct information: what is returned, why/who it is for, and the auth prerequisite. Nothing is repeated from the title or schema and the prerequisite is placed before it can bite.

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?

The tool is a 2-parameter read with no output schema but a description that already enumerates the returned sections. Practical prerequisites and payload content are covered; only minor details like note privacy are left implicit.

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 coverage is only 50%: 'since' is documented in the schema, but ownerKey has no schema description. The description compensates for exactly that gap by stating the key is required and where to obtain it, which is meaning beyond the structured fields.

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 and resource (returns the nation's situation report, doctrine, standing orders, private notes), which is concretely distinguishable from siblings like list_nations or briefing by the enumerated content. It does not explicitly contrast itself with those siblings, so it stops short of a 5.

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?

Frames the audience and purpose ('For a human head of state coaching their general') and implies read-only orientation versus the give_orders/submit_orders siblings. No explicit when-not or named alternative, but the context is clear enough to route correctly.

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