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

With no annotations, the description carries the full burden. It states the tool is a 'simple test' confirming server status, which implies non-destructive, read-only behavior. However, it does not detail any side effects or limitations. For a trivial tool with no parameters, this is acceptable but not exemplary.

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 sentence with no excess words. It is front-loaded with the core purpose and earns its place without any filler.

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?

Given the tool has zero parameters and an output schema exists (per context signals), the description sufficiently covers its straightforward behavior. It does not need to explain return values as per rubric rules.

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 has zero parameters, and the rule sets a baseline of 4. The description does not need to add parameter meaning since there are none.

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 states it is a 'Simple test tool' that 'confirms the WriteFreely MCP server is running.' This provides a specific verb-resource combination and naturally distinguishes it from sibling tools which perform content operations like browsing, publishing, or deleting.

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 description implies usage for checking server connectivity, which is distinct from sibling tools' purposes. While no explicit when-to-use or when-not-to-use guidance is given, the context is clear enough for an agent to understand this is a diagnostic tool.

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