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

The annotations already declare readOnlyHint=true and idempotentHint=true, so the tool's safe, read-only nature is clear. The description adds context about the guide's content but does not disclose return format, pagination, or any other behavioral traits beyond what annotations provide. There is no contradiction.

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, well-structured sentence that front-loads the topic and lists the key aspects of the guide. Every element earns its place, with no wasted words or repetition of the tool name.

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?

As a simple, read-only documentation tool with no parameters and no output schema, the description is sufficiently complete. It names the main topics of the guide, which is all an agent needs to decide whether to invoke this tool. It does not explain the return format, but that is unnecessary for a content guide with no structured output.

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 input schema has zero parameters, so the baseline is 4. The description compensates by explaining what the guide covers (authentication, environments, credentials, storage/rotation), which gives meaningful context without needing to describe parameter syntax or formats.

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 clearly identifies the tool's subject matter—authentication, environment selection, credentials, and safe storage/rotation—which distinguishes it from sibling guides like quickstart or webhook guide. However, it lacks an explicit verb like 'explains' or 'returns', making the action only implied by the tool name and context.

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?

No explicit guidance is given about when to use this tool versus sibling tools such as roki_get_quickstart or roki_get_webhook_guide. The only usage signal is the subject matter, which is implicit rather than stated. Neither alternatives nor exclusions are mentioned.

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