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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds useful content-level context—what a package includes—but does not disclose how the tool behaves, such as whether it returns a list, renders a page, or provides static documentation.

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 compact sentence with no filler or redundancy. It front-loads the resource name and includes concrete details, though it sacrifices clarity by omitting a verb and reading more like a label than an operational description.

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?

There is no output schema, and the description does not clarify whether invoking this tool returns data, opens a page, or presents static content. Although the zero-parameter read-only nature makes invocation simple, an agent cannot be certain what a call will yield or how it differs from clickphone_tarife or clickphone_pagina.

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 and an empty input schema, so the baseline of 4 applies. There are no parameters needing documentation, and the description's mention of package contents does not conflict with or obscure any parameter semantics.

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 names the resource—ClickPBX packages—and lists salient attributes such as monthly price, included accounts, simultaneous calls, and minutes. However, it is a noun phrase rather than an explicit action statement; it never says whether the tool lists, returns, or describes packages. It also does not distinguish itself from closely related siblings like clickphone_tarife.

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?

There is no guidance on when to use this tool versus alternatives. With seven sibling tools including clickphone_tarife, clickphone_pagina, and clickphone_ghid, the description provides no routing or exclusion context. Usage is only weakly implied by the noun phrase, not stated.

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