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

Annotations already declare destructiveHint=true, idempotentHint=true and closed-world scope, so the safety profile is covered. The description still adds substantive value beyond the annotations by disclosing the concrete consequence (meetings stop arriving) and the reversibility path (until a key is saved again), plus an authorization restriction. It does not detail what happens to previously received meetings or any confirmation behavior.

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?

Three short sentences, each earning its place: the action, the consequence, and the permission constraint. The action is front-loaded and nothing is padded.

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 destructive tool with annotations covering the safety profile, the description supplies effect, reversibility, and auth scope. A small gap remains around confirmation/irreversibility of what was already ingested, but nothing essential for correct invocation is missing.

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 and the baseline of 4 applies. No parameter-related gaps exist to compensate for.

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?

States a specific verb (Remove) and resource (the workspace's Granola key), and is clearly distinguishable from its sibling save_the_granola_key. An agent needs no schema to know what this does.

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 clause 'until a key is saved again' implicitly points to the re-save action, and 'For the owner only' names the precondition for use. It stops short of explicitly naming an alternative tool or stating when-not-to-call, so it is clear context rather than full routing guidance.

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