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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and a closed world, so safety is covered. The description adds useful content-scope context (licence number verifiable against the public register, limits on client protections), but says nothing about return format, caching or freshness.

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?

A single sentence that front-loads the resource and then lists its parts, with no filler. The noun-list style is slightly dense but every item earns its place as a hint about returned content.

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?

With no output schema, the description carries the burden of describing returned content, and it does so by enumerating the sections covered. Combined with annotations that establish it as a safe idempotent read, an agent has enough to call it correctly; only formatting/pagination detail is missing.

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 100% and the single 'language' parameter is fully documented with its enum and default in the schema itself. The description adds no parameter information at all, so the baseline 3 applies.

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 a concrete resource (GCC Brokers) and enumerates its contents: licensed entity, regulator, licence number, brand companies, Dubai office, client protections and contacts. That is far more specific than a tautology and the domain is clearly distinct from siblings like get_instrument or get_prices, though it never states a verb or explicitly contrasts itself with alternatives.

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 explicit when-to-use or when-not-to-use statement, but the content list implicitly signals the questions it answers (who is the broker, is it regulated, what protections exist), which is enough for an agent to route regulatory/company questions here rather than to the price or instrument tools.

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