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

Description reinforces annotations (readOnlyHint=true/openWorld=false) by stating it is read-only and side-effect-free. Adds value by disclosing no API calls are made, it returns server version and local client state, and that a failed write-access check predicts failures of listed sibling tools. No annotation contradiction found.

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?

Eminently functional, front-loaded description. It is a bit long but every sentence adds a key fact; no padding. Organized into what-it-returns, when-to-use, and exclusions.

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?

No output schema, but the description states precisely the return values (server version, client init, OAuth presence, write configure). No sibling write tools to distinguish since it is a diagnostic. No nested input params. For a zero-param check tool, this is complete.

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?

No parameters exist, a baseline of 4 is given per rubric. Schema is empty but with 100% description coverage; no parameter documentation is needed.

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?

States a specific verb+resource: 'Health check for the Reddit MCP server.' Clear read-only diagnosis tool. Distinguishes from siblings by noting it inspects only local configuration and never contacts Reddit.

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?

Gives explicit when-to-use: 'Use this first to diagnose setup/authorization issues.' Explicitly excludes checking Reddit status or connectivity, and notes write tools will fail if write access is absent.

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