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

Describes return fields (name, type, source, estimated size, status) and the 'where LinkedIn reports it' nuance. Without annotations, this provides necessary behavioral insight, though pagination is not mentioned (implied by page_size parameter).

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?

Three sentences, front-loaded with the main action, no redundancy. Every sentence adds value.

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 no output schema, the description adequately explains return fields and usage. It lacks error handling details but covers essential aspects for a list operation.

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?

Schema coverage is 33% (only 'type' has schema description). The description reinforces the 'type' enum values from the schema but adds no extra meaning for 'ad_account_id' or 'page_size'. It partially compensates by explaining the tool's output context.

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 clearly states 'List DMP segments attached to a LinkedIn ad account' and explains segment types (USER, COMPANY). This verb-resource pair is specific and distinct from sibling tools.

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?

Explicitly provides two use cases: auditing audiences before campaigns and confirming upload success. It gives context but does not exclude alternatives or mention when not to use.

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