journal

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states what content is returned and does not explain whether this is a read-only operation, what 'activated' means, how entries are computed, or whether any context limitations apply.

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 very short and contains no filler, but it is terse to the point of under-specification. It is concise as a noun phrase but does not provide enough structured information to be genuinely helpful.

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?

Although the tool is simple and an output schema exists, the description omits usage context, parameter semantics, and differentiation from sibling tools. An agent cannot determine when to invoke journal or how the 'country' default works, leaving important context missing.

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?

The sole parameter 'country' has 0% schema description coverage, and the description does not explain its meaning, accepted values, or default of 'player'. The phrase '该国' only loosely implies a connection to the country without any parameter-level detail.

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 identifies the resource (journal entries) and the scope (activated for the country), which is reasonably distinct from sibling tools like economy, politics, or military. However, it is a noun phrase rather than an explicit verb+resource statement such as 'Get the country's activated journal entries'.

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?

There is no guidance on when to use journal versus siblings such as overview, analyze_situation, or country. No alternatives, prerequisites, or exclusions are mentioned, so an agent must infer the intended use case.

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