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

With no annotations, the description carries the behavioral transparency burden. 'Static audit' and 'conservative' imply a non-mutating, cautious check, which is useful. However, it does not say what is checked, how failures are reported, or whether there are any side effects.

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 front-loaded sentence with no wasted words. It conveys the action and timing efficiently, though 'conservative' adds slight ambiguity and could be clarified.

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 tool, the invocation requirements are minimal, and the 'before opening' guidance provides useful context. However, with no output schema and no mention of what the audit returns or does on failure, the description leaves the agent guessing about the tool's result.

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%, and the description never mentions model_path or its expected format. The parameter name is fairly self-explanatory, but the description adds no constraints about accepted file extensions, absolute vs. relative paths, or required model formats.

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 ('run') and a clear resource ('static audit' of the model) and adds timing that helps distinguish it from opening or inspecting the model. It does not explicitly contrast with vensim_doctor, so it stops short of a 5.

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 phrase 'before opening the model in Vensim' provides a concrete trigger for when to use this tool, which is clear usage guidance. It does not mention exclusions or alternative sibling tools, but the timing context is sufficient for basic tool selection.

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