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

Annotations already declare the safety profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false, openWorldHint=true), so the bar is lower. The description adds genuinely useful non-schema behavior: submissions are human-read and explicitly not answered, setting correct response expectations. It could still say more about rate limits or 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?

Two economical sentences with zero filler, and the core action is front-loaded before the expectation-setting clause. Every phrase earns its place.

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?

It handles the response expectation well ('not answered') which matters for a one-way submission tool with no output schema, but with four parameters and 25% schema coverage it leaves the agent under-informed about message, category, and severity, which are the fields the agent must actually populate.

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 coverage is only 25% – just request_id is documented. The description vaguely echoes the category enum ('bug, missing data, idea') but says nothing about the required message field, the severity levels, or how request_id links a report to a call, so it fails to compensate for the coverage gap.

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 and recipient ('Tell the SimianX team') plus the kinds of submissions (bug, missing data, idea), which is enough to separate it from the sibling feedback_list that reads feedback rather than sending it. It stops short of explicitly naming that sibling, so it's clear but not fully differentiated.

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 implied by the enumerated cases ('a bug, missing data or an idea'), so an agent can infer when to call it. However, it gives no explicit when-not guidance and never routes the agent to feedback_list for reading existing reports.

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