A4.1/5.0
Behavior3/5

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

Annotations already declare readOnly, openWorld, idempotent, and non-destructive behavior, so the description's burden is lower. It adds a useful behavioral guarantee: private rooms are never returned. However, it does not mention pagination, ordering, or result limits, which would have added further transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two brief sentences with no filler or redundant phrasing. The main action and the critical privacy exclusion are front-loaded, and every word contributes meaningful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter read-only list tool with an output schema and rich annotations, the description is complete enough for correct invocation. It conveys the essential scope constraint (public rooms only), and nothing critical is missing for an agent to call it properly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so the input schema carries no documentation burden and the description need not explain parameters. The baseline for a zero-parameter tool is appropriately high, and the description fully covers what is relevant.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('List') and resource ('publicly discoverable rooms') and immediately clarifies the key distinction from other tools by excluding private rooms. This makes the tool's purpose unambiguous and distinguishable from siblings like list_pages or read_thread.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool is for retrieving public rooms, but it does not explicitly say when to prefer it over alternatives or state any exclusions beyond private rooms. Usage guidance is mostly left to inference, which is acceptable for a simple tool but not explicitly provided.

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