run_behavioral_simulation

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

With no annotations, the description carries the full burden and only reveals that it invokes XSIM for behavioral simulation. It omits side effects, expected duration, whether project state changes, or the need for confirmation/timeout controls hinted at by the schema.

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 filler; it communicates the core action immediately. It is concise, though the 10-parameter tool would benefit from more structured information.

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 complexity (10 parameters, no annotations, and zero schema description coverage), this description is incomplete: it omits prerequisites, side effects, and behavioral caveats. The existence of an output schema covers return values, so that is not the main gap.

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 explains none of the 10 parameters (simset, run_time, vcd_name, export_vcd, execution_intent, etc.). The word 'fileset' only loosely maps to simset and does not compensate for the missing parameter documentation.

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 action ('Run'), a precise target ('Vivado XSIM behavioral simulation'), and a constrained scope ('configured simulation fileset'). This separates it from siblings like configure_simulation, get_simulation_result, and run_synthesis without needing to open the schema.

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?

'Configured simulation fileset' implies a prerequisite and tells the agent this runs rather than configures or retrieves results, but it does not explicitly name alternatives, state when not to use it, or describe what to do if the fileset is not configured.

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