flexsim_get_time

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states what the tool does but doesn't describe how it behaves—e.g., whether it returns a timestamp format, if it requires an active simulation, error conditions, or performance implications. For a tool with zero annotation coverage, this is a significant gap in transparency.

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, clear sentence with zero waste—'Get current simulation time' is front-loaded and perfectly concise. Every word earns its place, making it easy for an agent to parse quickly without fluff.

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 simplicity (0 parameters, no annotations, but with an output schema), the description is minimally adequate. It states the purpose but lacks context on usage, behavior, or output format. The output schema existence means the description doesn't need to explain return values, but it should still cover more behavioral aspects for a tool in a simulation environment.

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?

The tool has 0 parameters, and schema description coverage is 100%, so there's no need for parameter documentation in the description. The baseline for 0 parameters is 4, as the description appropriately avoids unnecessary parameter details. It doesn't add or detract from parameter understanding.

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 'Get current simulation time' clearly states the verb ('Get') and resource ('current simulation time'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'flexsim_get_statistics' or 'flexsim_get_node_value' beyond the obvious time focus, so it doesn't reach the highest tier of sibling differentiation.

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 description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., requires a running simulation), exclusions, or comparisons to similar tools like 'flexsim_step' or 'flexsim_run_to_time' for time-related operations. The agent must infer usage from the name alone.

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