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

With no annotations, the description must carry the full transparency burden. 'Explain' clearly indicates a non-mutating, informational tool, but it does not disclose the output format (e.g., text, structured data) or any side effects. For such a simple tool, the behavioral disclosure is minimal but not contradictory.

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, concise sentence that is front-loaded with the verb and subject, containing no unnecessary words or filler. It perfectly matches the conciseness ideal.

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-parameter, no-output-schema help tool, the description is nearly complete. It names the two components being explained and the relationship. It could add a note about its intended audience or whether it includes setup steps, but given the simplicity, it covers the essential aspects.

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 has zero parameters, so the schema is empty and there is nothing to explain in the description. Per rubric, 0 parameters baseline is 4, and no further info is needed.

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 tool's purpose with a specific verb ('Explain') and a well-defined subject (how banking and planning memory work together). It distinguishes itself from all sibling tools, which are data-focused operations, while this is an educational/explanation tool.

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?

The description implies usage when the agent or user needs to understand the integration between Plaid CLI and this MCP, but it does not explicitly say 'use this when' or mention any exclusions or alternatives. Since there are no sibling tools with similar purpose, the guidance is implicit but not fully explicit.

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