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

readOnlyHint=true already establishes this is a safe, non-mutating read, lowering the burden on the description. The description adds the useful behavioral fact that the content is static, pre-written FAQ material spanning named topic areas rather than account-specific data, but says nothing about freshness or whether answers are generic.

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 front-loaded sentence with no waste; the topic enumeration is dense but earns its place by signalling coverage. Slightly list-heavy, but nothing redundant.

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 an output schema present, return values need no explanation, and with no parameters the input side is trivially complete. What is missing is situational context: in a 40+ sibling toolset containing other informational endpoints, the agent still has to guess when FAQ content is preferred over get_why_us or web_search.

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 takes zero parameters, so per the rubric the baseline is 4. There is nothing for the description to clarify beyond confirming no input is required to scope the FAQ topic.

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 precisely (a static FAQ covering buying, selling, fees, payment, trust, privacy, help) and is clearly distinct from action-oriented siblings like create_task or get_deliverable. It stops short of differentiating itself from semantically adjacent informational tools such as get_why_us or get_protocol, so it is clear but not fully diagnostic.

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 statement of when to reach for this tool versus alternatives. The topic list implies 'use this when the user asks a general platform question,' but with get_why_us and get_protocol in the sibling set, the agent gets no routing rule.

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