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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds behavioral context by stating that the tool receives company details and returns the package, monthly price, inclusions, and follow-up pages. This meaningfully supplements the annotations without contradicting them.

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 dense sentences with no filler. The main action and output are front-loaded, and the disambiguation from clickphone_pachete is placed at the end as a crisp usage note. Every sentence earns its place.

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 read-only recommendation tool with no output schema, the description covers the purpose, inputs, expected output, and alternative tool. It could go slightly deeper on the exact output format, but the schema documents optional parameters and annotations cover side-effect behavior.

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 100%, so the baseline is 3. The description highlights the key input categories (users, existing PBX, remote work) but adds no parameter-level detail beyond the schema and does not mention minute_lunare or apeluri_simultane. The schema itself does the heavy lifting here.

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?

Description opens with a concrete verb and resource: 'Recomandă soluţia şi pachetul potrivit pentru o firmă' and names the two possible solutions (ClickPBX or SIP Trunk). It also explicitly differentiates itself from clickphone_pachete by saying it is for fit, not for price. An agent can recognize when this tool applies 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.

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

The description gives an explicit usage rule: use it for 'ce mi se potriveşte', not for the price of a specific package, which belongs to clickphone_pachete. It also lists the decision inputs (users, existing PBX, remote work) that signal when this tool is appropriate.

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