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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only the vague phrase 'from the queue' and says nothing about lookup failures, permissions, or what a missing exception returns, so it contributes almost no context beyond the annotations.

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?

Brevity here reflects under-specification rather than conciseness: it is a fragment with no verb and nothing front-loaded of value. One complete sentence stating what is retrieved would cost no more space and be far more useful.

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 simple read-by-ID tool the annotations cover the safe-read profile, but with no output schema the description should at least characterize what an exception record is and what is returned. It leaves the agent with only the tool name to work from.

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 0% for the single required exception_id parameter, so the description carries the burden of explaining it and fails to — no format, no source of the ID, no relationship to the queue. It is marginally better than the zero-coverage multi-param case only because a single 'get by ID' parameter is partly self-evident.

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 is a noun fragment, 'An exception from the queue,' that essentially restates the title 'Get an exception' without a verb or scope. It does not distinguish this tool from siblings like list_open_exceptions, resolve_exception, or escalate_exception, so an agent cannot tell which retrieval semantics apply.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as list_open_exceptions for enumeration or resolve_exception/escalate_exception for acting on an exception. The agent is given nothing to route on beyond the name.

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