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

Annotations only declare readOnlyHint=false and openWorldHint=false; the description adds the crucial behavior that no meeting exists until the human confirms, that the link must be presented rather than embedded, and that name/email must not be put into the URL. That is real behavioral disclosure beyond structured fields.

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?

Two tight sentences: the first states what is produced, the second states the required handling. Every clause earns its place, and the prohibitions are front-loaded where they matter.

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?

There is no output schema, and the description compensates by specifying the return shape (URL plus name and email as separate fields). Combined with the confirmation workflow, an agent has everything needed to call and use this tool correctly.

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?

Schema description coverage is 100% and both parameters are documented there, so the baseline is 3. The description adds only that name and email come back as separate fields and are shown alongside the link, which is return-value context rather than new parameter meaning.

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 a specific resource (the agency's booking URL) and its scope (30-minute meeting), plus what comes back alongside it. It is clear on its own, but it never distinguishes itself from the sibling create_text_link, which an agent must disambiguate without help.

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?

Usage is unusually explicit: hand the URL to the human, have them enter name and email on the page, and do not treat the meeting as booked. It stops short of naming an alternative tool or stating when a different link type would be preferred over this one.

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