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

Annotations already declare this is a non-read-only, open-world, non-destructive mutation, so the safety profile is covered. The description adds the notion of responding to a request with an alternative time, but it doesn't explain what happens to the original request, whether the student is notified, or whether the request remains pending.

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 front-loaded sentence with no filler. It is efficient, though its brevity contributes to the under-specification noted elsewhere.

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 mutating workflow tool with no output schema, the description omits important context: the state transition of the request, whether a note is sent, and what happens after the counter-proposal. Annotations cover mutation safety, but the description does not fill the remaining gaps.

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 75%, with good descriptions for requestId, response_note, and the ISO 8601 requirement for proposed_date_time. The description adds no parameter meaning beyond the schema, so the baseline of 3 applies given the relatively high coverage.

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 states a specific verb and resource: answering a student's class change request with an alternative time. It clearly conveys a counter-proposal action, though it doesn't explicitly differentiate itself from close siblings like accept_class_change or reschedule_class.

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?

There is no guidance on when to use this versus accept_class_change, decline_class, reject_class_change, or reschedule_class. The only implied context is that it applies to class change requests, with no exclusions or prerequisites stated.

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