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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It describes the simulation's domain characteristics but says nothing about whether the tool is read-only, what it returns, whether it has side effects, or any execution constraints. The agent is left to guess at operational behavior.

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. However, for a tool with 11 parameters, this brevity comes at the cost of essential detail, making it under-specified rather than effectively concise.

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?

Given the tool's complexity (11 parameters, no output schema, no annotations), the description is far from complete. It omits any explanation of parameters, usage context, or return values, leaving the agent with insufficient information to invoke the tool 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?

There are 11 parameters with 0% schema description coverage, and the description adds no parameter-level information whatsoever. It does not explain any of the inputs (e.g., dt, step_time, pipeline_delay, include_trajectory), leaving them entirely undocumented.

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 states a specific verb ('Simulates') and resource ('dynamic inventory behavior') and names key simulation features (pipeline lags, limit-cycle capture, optional noise). However, it does not differentiate this tool from its siblings (compare, diagnose, optimize, etc.), leaving the agent to infer that 'simulate' is distinct from those analyses.

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 guidance on when to use this tool versus the alternatives, no mention of prerequisites, and no exclusions. The description only states what the simulation does, not when an agent should choose it over the sibling tools.

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