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 reveals the key conditional behavior ('Optional annual revenue (AED) auto-selects large vs SME') and previews output content, but does not mention data sources, recency, error conditions, or that the operation is read-only. It is adequate but not richly transparent.

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?

Two sentences deliver the core purpose, the segment options, the technical baseline, and the conditional parameter behavior with no fluff. The main action and resource are front-loaded, making the tool easy to scan.

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 simple read-only tool with two optional parameters and no output schema, the description covers purpose, parameters, and output categories adequately. It does not detail the exact shape of 'timeline' or 'next actions', but the absence of an output schema is partially compensated by the explicit enumeration of return content.

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 adds meaningful cross-parameter semantics by explaining how annualRevenueAed influences segment selection when businessType is all or omitted, which the schema alone does not fully convey.

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 uses a specific verb ('Return') and identifies a precise resource: the UAE e-invoicing mandate timeline, technical baseline, and next actions. It clearly distinguishes from sibling tools like check_invoice_compliance or generate_pint_ae_xml, which focus on compliance checking and XML generation rather than mandate requirements.

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 makes the intended use case clear by stating exactly what information is returned and for which business segments. While it does not explicitly name alternatives or exclusions, the distinct purpose is enough for an agent to select it over the sibling tools in most contexts.

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