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

The verb 'List' conveys a read-only operation, and 'organization suppressions' scopes the data, which is useful in the absence of annotations. However, the description does not disclose pagination behavior, response shape, ordering, or whether only active suppressions are returned. With no annotations, the description carries the full transparency burden and only partially meets it.

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, readable sentence with no filler or repetition. It is appropriately short for a simple list operation, though slightly more detail could have been added without hurting conciseness.

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 straightforward list operation, the combination of description and fully documented input schema is mostly sufficient for invocation. However, there is no output schema and no description of what data is returned, and the term 'suppressions' is vague. The definition is adequate but leaves meaningful gaps for an agent.

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 input schema provides 100% coverage for all three parameters, including descriptions for limit, cursor, and organization_id. The description adds no parameter-specific meaning beyond tying the operation to the organization, so the baseline of 3 is appropriate.

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 states a clear verb ('List') and resource ('organization suppressions'), making the tool's basic purpose unambiguous. It is distinguishable from the adjacent commsharbor_suppression_create tool, though it doesn't explicitly name that sibling. The term 'suppressions' is not elaborated, leaving some ambiguity about what entities are returned.

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?

No guidance is given for when to use this tool versus alternatives, and no alternatives are mentioned. The agent must infer from the tool name and the sibling list that this is the read/list counterpart to suppression creation, rather than being told directly. There is no when-not-to-use or prerequisite context.

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