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

No annotations are provided, so the description carries the full behavioral burden, and it discloses very little. Calling it a 'gateway' to an external API hints at a proxy/read passthrough, but nothing states whether calls are read-only, whether credentials or a network dependency on forex.mobile are required, what happens on an invalid broker slug, or how failures surface.

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 with no filler, and the three capabilities are listed up front. It is efficient, though the gateway metaphor consumes words that a direct verb would have used more productively.

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 only three fully documented parameters, one required, a complete enum, and no output schema, the structured fields do most of the work. What is missing is behavioral context an agent would want before invoking an external-API proxy — failure modes, response shape in prose, or any auth/environment prerequisites.

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% and the endpoint enum is fully enumerated, so the schema already explains broker, broker_b, and endpoint. The description adds only the vocabulary of the three result types, which roughly mirrors the enum values but does not clarify the conditional dependency (broker for 'broker', broker_b for 'compare') beyond what the schema says.

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 (real forex rate data, broker list, broker comparison) and its source (forex.mobile API), which maps cleanly onto the four endpoint modes. It lacks a crisp verb like 'get/fetch' — 'pintu gerbang untuk meminta data' is metaphor rather than action — but an agent can still tell what the tool returns.

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?

Listing the three data categories implicitly tells the agent when to reach for this tool, but there is no explicit 'use this when…' statement, no exclusions, and no referenced alternatives. The sibling tools (skills, frida, apk) are unrelated, so mis-routing risk is low, which keeps this at an implied-usage 3 rather than lower.

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