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

With no annotations, the description carries the full burden of behavioral disclosure, but it only restates the action. It does not explain whether the change is session-scoped, whether the path must exist, whether it affects subsequent tool calls, or what happens on invalid paths. This is a significant gap for a tool that modifies session state.

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?

The description is a single, efficiently worded sentence with no fluff or redundancy. It is front-loaded with the action verb and resource. It earns its place, though it is arguably too sparse to be an excellent definition.

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 tool with 2 parameters and no annotations, the description is under-specified. It does not explain when this command is needed, what the returned output means (despite an output schema existing), or how the working directory interacts with the rest of the Abaqus session. An agent would have to guess at critical context.

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%, so the description must compensate for the parameters but does not. The 'path' parameter is self-explanatory by name, but the description does not clarify path format (absolute vs relative), validity rules, or the meaning of 'timeout'. The timeout parameter is completely undocumented in both schema and description.

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 ('Change') and a clear resource ('current Abaqus working directory'). It is immediately differentiable from all sibling tools, none of which perform this function, and there is no ambiguity about what the tool does.

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 guidance is given about when to use this tool versus alternatives, nor any mention of prerequisites or side effects. The use case is only implied by the verb 'Change', but there is no explicit context about needing to set a working directory before running scripts or accessing files. There are also no exclusions or conditions stated.

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