plaid_link_token_create

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

No annotations are provided, so the description must fully convey behavior. It does not mention that the token is returned, its expiration, or that frontend integration is required. This is insufficient for an agent to understand side effects or lifecycle.

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 sentence, which is concise but lacks any structural breakdown. It is appropriately sized for a simple action but could benefit from additional structuring (e.g., separate sections for key details).

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 the complexity of Plaid Link token creation (10 parameters, financial context), the description is severely incomplete. It does not explain the returned token's purpose, the flow after creation, or how to handle the response. With no output schema, this omission is critical.

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 has 60% description coverage, meaning some parameters lack descriptions. The tool description adds no further meaning to any parameters, failing to compensate for schema gaps.

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 'Create' and the resource 'Plaid Link token', and it implies the purpose of starting the Plaid Link flow. It distinguishes from sibling tools like 'plaid_accounts' and 'plaid_balances' which retrieve data rather than initiate a flow.

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, such as when to use update mode versus initial creation, or any prerequisites. The description only states the function without contextualizing its usage.

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