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

With no annotations, the description carries the transparency burden. It clearly indicates a retrieval operation ('Ritorna') with no side effects, and specifies that the result is a catalog of skills with their ids. It does not mention auth or error cases, but for a simple no-parameter list operation this is not a material gap.

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 two short sentences. The first sentence states the core behavior and output; the second sentence gives targeted sequencing guidance. Every part earns its place with no redundancy.

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 zero-parameter, no-output-schema list tool, the description tells the agent what it returns, where it fits in the workflow, and which sibling it precedes. Nothing essential is missing for correct invocation.

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 zero parameters, so the schema fully covers input. The description adds useful context by explaining why the output matters ('per sapere quale skill_id passare'), which helps the agent use the returned identifiers correctly.

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 concrete verb ('Ritorna') and a specific resource ('catalogo delle competenze disponibili su Rentme'), and notes that each entry includes its id. This clearly distinguishes it from the sibling tools, which check task status or create tasks.

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 explicitly instructs the agent to call this tool PRIMA di rentme_create_task when a specific skill must be associated with a task, in order to learn the skill_id to pass. This is direct, actionable guidance about when to use it and how it relates to a named sibling.

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