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. It usefully discloses 'No authentication required,' which is genuine behavioral context, and 'Get' implies a read-only operation. But it says nothing about result size, pagination, or caching/staleness of FAQ content.

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 short sentences, front-loaded with what the tool returns. No wasted prose, though the middle sentence ('help users with common issues') is generic filler that adds little routing value.

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, single-optional-parameter read tool with no output schema, the description is nearly complete: it states purpose, usage context, and the notable no-auth property. The main gap is that it neither hints at the return shape nor differentiates from related help/info siblings.

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% with a single enum parameter and a default, so the schema already fully documents 'topic.' The description adds no syntax, default-behavior, or filtering semantics beyond what the schema provides, making the baseline 3 appropriate.

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 verb+resource are explicit: 'Get frequently asked support questions and answers.' It clearly states what is returned. However, it does nothing to distinguish itself from closely related siblings such as get_subscription_help, get_pricing_info, get_feature_list, and get_usage_guide, all of which could plausibly cover 'common issues.'

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?

'Use this to help users with common issues' implies a usage context but names no alternatives and no exclusions. An agent cannot tell from this text whether to route a billing question here or to get_subscription_help/get_pricing_info.

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