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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world scope, so the safety profile is covered. The description's one added contribution is the visibility constraint, which usefully warns that results are permission-scoped, but it says nothing about error behavior for inaccessible IDs or lookup-failure semantics.

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 with zero filler. It is efficiently sized, though the brevity edges into under-specification rather than maximal density of useful information.

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?

An output schema exists, so return values need not be explained, and annotations cover safety. What remains missing for a simple lookup tool is any linkage between the required ID parameter and where an agent obtains it, plus lookup- failure expectations.

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 schema has 0% description coverage and the description never mentions supportRequestId — no format hints, no statement that it is the ID returned by list_support_requests. The schema's pattern and length constraints exist, but the description does nothing to compensate for the missing semantic layer.

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 ("Read") and resource ("support request") and adds a visibility scope ("visible to the connection owner") that distinguishes it from the sibling list_support_requests, which returns collections. It stops short of explicitly naming the sibling, but the singular-resource framing makes the distinction clear.

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 statement of when to use this versus list_support_requests, no mention that it requires a known ID, and no guidance on what happens for IDs outside the owner's visibility. The agent must infer usage entirely from the tool name.

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