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

No annotations provided, so description handles full burden. Declares read-only nature and graceful skipping of probes. Could add auth requirements or return structure, but current info is solid.

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 sentences, front-loaded with key purpose. Every sentence adds value: what it does, read-only, graceful handling, usage guidance.

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?

Simple tool with no parameters and an output schema. Description covers purpose, behavior, and when to use. No gaps given context signals.

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 (0 params, schema coverage 100%). Baseline 4 per rules. Description doesn't need param details.

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's a 'single-call self-diagnostic for stability and dependency status' and positions it as a preflight check. It distinguishes from sibling tools by noting it avoids juggling connect/list/model_info.

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?

Explicitly recommends usage as a preflight from any LLM agent. Describes graceful behavior when no connection is active and contrasts with alternative approaches.

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