definir_molde_ace

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

With no annotations, the description carries the full behavioural burden. It does disclose the mutations performed (sets printer, filament profiles and real spool order) and implies a prerequisite (project must come from Anycubic Slicer Next with ACE synchronized), but says nothing about what happens to previously configured values, whether the operation is reversible, or what errors arise from an invalid/incompatible 3MF.

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?

Three short sentences with no filler, and the core purpose is front-loaded before the usage conditions. Slightly less efficient than it could be because the second sentence's content (what gets configured) could have been folded into the first.

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 single-parameter mutation tool with no annotations and no output schema, the description establishes purpose, effect and triggers, which is minimum viable. It still leaves the agent guessing about preconditions, failure modes and the consequence of overwriting an existing configuration.

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 coverage is 0% for the single parameter 'projeto_3mf', so the schema adds nothing. The description partially compensates by implying the argument is a project file produced by Anycubic Slicer Next with ACE synced, but it never states whether it is a path, a name, or whether it must already be listed by listar_3mf.

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 ('usa ... como molde' / define) and a specific resource (a project saved by Anycubic Slicer Next with ACE synced), and names what it configures: printer, filament profiles and real spool order. That differentiates it from generic siblings like ver_ace or listar_3mf, though the boundary with alterar_slot_ace is not drawn.

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?

It gives two triggering conditions ('quando o usuário trocar o tipo de material de algum slot' and 'na primeira configuração'), which is real usage context. However, it names no alternative and does not explain why this template-definition tool is the right one when alterar_slot_ace exists for per-slot material changes, leaving the agent to infer the split.

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