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

With no annotations provided, the description carries the full burden of behavioral disclosure. It describes returned content ('commands ... with parameters and descriptions') but does not state that the operation is read-only, whether it has side effects, permission requirements, or response format.

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, front-loaded sentence with no obvious filler. It could be slightly clearer about the action being performed, but it is efficiently sized for a simple catalog tool.

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?

Given zero parameters, no output schema, and low complexity, the description provides some context about what is returned and its relation to vocabulary signatures. However, it does not fully explain the return structure or when an agent should choose this tool over siblings, leaving a clear gap.

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 input parameters, so there is no input schema semantics to explain. The mention of 'parameters and descriptions' refers to the output content, not input parameters, and does not require further clarification.

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 as the set of commands a citizen may call, including their parameters and descriptions, but it does not use a clear verb or explicitly distinguish the tool from siblings like vocabulary or schema. The phrase 'same verbs as the vocabulary's signatures' hints at a relationship but leaves the exact action implied rather than stated.

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 versus alternatives such as vocabulary, schema, or check. The description only describes content, not selection criteria or exclusions.

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