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

No annotations exist, so the description bears full burden. It usefully discloses an auth requirement and where to obtain the key ('the owner key from the app's My Nation tab'), which is real context. However, it says nothing about the incremental/'since' behavior, permissions scope beyond the key, or rate limits, leaving meaningful gaps for a no-annotation tool.

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 tight sentences: purpose/audience first, returned payload second, prerequisite last. No filler, though the ordering puts the audience line ahead of the core purpose statement.

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?

With no output schema and no annotations, the description does list the returned content, which is the right move. But it omits the incremental-fetch behavior implied by the 'since' parameter and offers no privacy/permission framing for a tool that exposes 'private notes'.

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 50% — 'since' is documented in the schema itself, while 'ownerKey' is undocumented there. The description partially compensates by telling the agent where the ownerKey comes from, but adds no syntax, format, or behavior (e.g. cursor semantics) beyond that.

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 (returns) and enumerates the concrete payload: situation report, general's doctrine, standing orders, private notes. This clearly distinguishes it from siblings like list_nations or briefing, though without explicitly naming which sibling is the alternative.

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 audience is stated ('a human head of state coaching their general'), which implies usage, but there is no explicit when-to-use or when-not-to-use guidance and no alternative tool is named. An agent must infer how this differs from briefing or list_nations on its own.

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