read_test_file

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

With no annotations, the description carries the burden; 'read' communicates a non-destructive operation and 'parse/show structure' hints at the output. It does not mention error behavior, file existence requirements, or side effects, but for a read tool the core safety trait is reasonably clear.

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 no redundant words. It states the core action and result in an efficient manner.

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 one-parameter read tool with full schema coverage, the description is mostly adequate, but without an output schema it leaves 'show its structure' vague—an agent may not know whether it returns parsed JSON, a tree, or a summary. It also provides no guidance on prerequisites such as the file needing to exist or be valid JMX.

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 100% and the parameter description already defines testfile as the path to the .jmx file. The description adds 'JMeter' context but no additional parameter-level semantics beyond the schema.

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 ('read and parse') and names the resource ('JMeter test file') and outcome ('show its structure'). It is clearly distinguishable from sibling creation/execution tools, but it does not explicitly contrast with any sibling.

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?

No explicit when-to-use or alternative guidance is given. The intended use (inspect an existing JMX file's structure) is only implied by the verb and the surrounding sibling tools.

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