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

Annotations already declare read-only, idempotent, non-destructive, and closed-world behavior. The description adds useful topical scope, but does not state the return format, guide length or version, authentication requirements, or whether this is the canonical entry point. With annotations covering safety traits, a 3 is appropriate.

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?

The description is a single front-loaded sentence naming the resource and its covered topics with no wasted wording. Every listed topic earns its place by helping the agent decide whether the guide contains what it needs.

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 zero-parameter read tool, the content list plus annotations provide enough to call it correctly and understand its scope. It falls short of 5 because it does not state the output form or explicitly frame the guide as the recommended starting point for onboarding.

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?

There are zero parameters, so there is no parameter meaning to add beyond the empty schema. The baseline for a no-parameter tool is 4, and the description does nothing to create parameter confusion.

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 identifies the resource as the full guide to Open Uncensored for agents and enumerates the topics it covers, which distinguishes it from action-oriented siblings like buy_credits and chat. It stops short of an explicit retrieval verb such as 'read' or 'returns,' which keeps it from a 5.

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 topic list implies this is the onboarding/reference tool to consult before buying a key or calling the API, but the description never explicitly states when to use it, when not to use it, or how it relates to sibling tools. Usage is implied rather than directed.

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