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

With no annotations provided, the description carries the full burden and clearly signals a read-only lookup behavior via 'Get'. It also discloses the scope ('common JMeter exceptions') and the type of content returned: root causes, config fixes, and remediation steps.

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?

One focused sentence front-loads the purpose and includes concrete examples that help an agent form valid queries. Every part of the description contributes to understanding the tool.

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 one-parameter lookup tool with no output schema, the description is complete: it tells the agent what the tool returns, what inputs are expected, and in which error situations it is useful. No additional context is needed to invoke it correctly.

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 100%, and the query parameter is already well documented in the input schema with examples. The tool description reinforces accepted inputs but adds no meaningful parameter semantics beyond what the schema provides.

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 uses a specific verb ('Get') and names the exact resource: root causes, OS/JVM config fixes, and remediation steps for JMeter exceptions. It is clearly differentiated from siblings like lookup_jmeter_property by focusing on error playbooks rather than generic JMeter properties.

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 examples of exceptions imply when to use it: when encountering JMeter errors such as BindException or SocketTimeoutException. However, it does not explicitly state when not to use it or mention alternative tools like search_jmeter_docs or tune_linux_os.

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