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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds meaningful content-level disclosure: it returns a booking link and a description of the first call, which clarifies that this is an informational tool rather than one that actually books a slot — important given the action-sounding name.

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?

A single front-loaded sentence that enumerates the three things returned, with no filler. It is slightly coy in phrasing ('and what happens next') where a direct statement of return content would be tighter.

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, read-only content tool with no output schema, the description covers the gist of the return but never states the format or explicitly tells the agent this does not perform a booking. Given five sibling tools, the absence of routing guidance leaves a real gap.

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 is nothing for the description to disambiguate. Per the rubric, a 0-parameter tool has a baseline of 4.

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 names the concrete payload — the booking link, what the first call covers, what happens next — which is more specific than the bare title. It is distinguishable from the sibling content tools (free_resources, wise_mango_services) only implicitly, since it never names an alternative.

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?

'How to start working with Wise Mango' implies the trigger context (a user asking how to engage/onboard), but there is no explicit when-to-use, when-not-to-use, or pointer to a sibling tool. Usage must be inferred from the framing sentence alone.

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