plaid_identity

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

With no annotations, the description falls short. It implies a read operation but does not disclose behavioral traits such as authentication requirements, rate limits, or the nature of the data returned.

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 very concise with one sentence, but it lacks structure. While brevity is good, it should still provide essential context.

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 annotations, no output schema, and 0% schema description coverage, the description is incomplete. It fails to explain the output, prerequisites (like obtaining an access_token), or how this tool fits into the Plaid workflow.

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 schema has 0% description coverage, and the tool description adds no meaning beyond parameter names. Although parameter names are self-explanatory, the description should elaborate on their purpose or usage.

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 the verb 'Get' and the resource 'identity information for accounts linked via Plaid', which is specific. However, it does not differentiate from sibling tools like plaid_accounts or plaid_balances, which also retrieve account-related data.

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 provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions.

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