aras_create_part

Create a new part with schema and list validation, optionally attaching it to a parent assembly in the BOM.

Instructions

Behavior3/5

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. It does disclose meaningful behavior: the tool validates the schema and list values, and it can optionally attach the part to a parent assembly. However, it leaves important operational details unclear, such as what actually happens on execution, whether dryRun prevents persistence, and what error or return behavior occurs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single efficient sentence with no filler. It front-loads the core action ('Crea una Part') and immediately follows with the distinctive behaviors that separate it from sibling tools.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 11 parameters, only 1 required, a 36% schema description coverage, no annotations, and no output schema, this description is not complete enough. It does not explain required inputs, dryRun behavior, return values, permissions, or failure conditions, so an agent has to infer too much operational detail from parameter names and context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds useful context for parameters involved in validation and BOM attachment, suggesting that list-valued parameters such as make_buy and unit are checked against existing values, and that parameters like sottoAssieme are intended for parent assembly linkage. That said, with only 36% schema description coverage, most of the 11 parameters still lack meaningful semantic explanation in both the schema and the description itself.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states exactly what the tool does in one combined verb: it creates a Part with validation constraints and optional BOM attachment to a parent assembly. This distinguishes it from generic creation tools such as aras_create_item and aras_create_document, so an agent can tell it apart without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to choose aras_create_part over aras_create_item, aras_create_document, or other creation tools. The usage context is only implied by the phrase 'Crea una Part', with no mention of exclusions, prerequisites, or conditions that should route the agent to a sibling tool.

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