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

No annotations are provided, so the description carries the full burden. It does not disclose any behavioral traits such as what happens after connection, whether it is reversible, or any side effects like overwriting existing connections. This is insufficient for a potentially mutative tool.

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 of 10 words, conveying the essential purpose without any fluff. It is front-loaded and efficient.

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 connection tool with no output schema, the description lacks important context such as prerequisites (e.g., existing Zernio profile), what 'connect' entails, and expected outcomes. It feels incomplete for guiding an agent on correct invocation.

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 already provides descriptions for all three parameters (profileId, accessToken, businessAccountId), covering 100% of parameters. The description adds the context of 'Meta Business credentials' but does not add detail beyond the schema, earning the baseline score.

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 action (Connect), the resource (WhatsApp Business account), and the method (by providing Meta Business credentials). It is distinct from sibling connection tools like zernio_connect_bluesky because it specifies the platform.

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 the tool should be used when setting up a WhatsApp Business connection with Meta credentials, but does not explicitly state prerequisites or when not to use it. No alternative tools are mentioned, but siblings are for other platforms.

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