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

With no annotations, the description must carry the behavioral burden. It does disclose two useful traits beyond the schema: the operation is read-only and incurs no cost. It omits return shape, ordering, or pagination, but for a zero-arg read-only list the disclosure given is reasonable.

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 short clauses, front-loaded with the core purpose and followed by usage and the read-only/free traits. Nothing is wasted.

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-arg, read-only list tool with no output schema, the description covers purpose, usage, and cost/safety profile. It could say a bit more about what fields come back since there is no output schema, but it is largely complete.

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 takes zero parameters, so there are no parameter semantics to explain; baseline for 0 params is 4. The description correctly implies no input is required.

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?

States a clear verb+resource ('List the LinkedIn accounts connected to this workspace') so the agent knows exactly what is returned. However, the sibling 'list_linkedin_accounts' is near-identical, and the description does nothing to distinguish the two, which is the main clarity gap.

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?

Implied usage is given ('Useful to see which account owns a conversation'), which hints at when to reach for it. But there is no explicit when/when-not guidance and no mention of how it relates to the confusingly similar 'list_linkedin_accounts' sibling.

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