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

The phrase 'Get information' implies a read-only, non-destructive operation, which is meaningful given that no annotations are provided. However, the description does not disclose output format, error behavior, or what exactly is returned, leaving part of the behavioral burden unmet.

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 a single clear sentence with no filler. It front-loads the action and the resource, making it immediately scannable and efficient.

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 zero-parameter tool, the description is minimally sufficient, but it does not explain what the returned information will look like, how it relates to sibling tools, or whether the response is structured. With no output schema or annotations, a bit more contextual detail would improve completeness.

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 tool has zero parameters, so the baseline for parameter semantics is 4. There is nothing for the description to add beyond the schema, since the input schema already fully covers this aspect.

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 uses a specific verb ('Get information') and names a distinct resource ('the available experience library'), so an agent can see what the tool does. It does not fully specify what 'information' is included or explicitly distinguish it from siblings like list_modes, but the resource is concrete enough to be useful.

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 this tool instead of alternatives such as list_modes or health. The intended use is only implied by the tool name and the phrase 'available experience library,' with no exclusions or comparison to sibling tools.

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