Garmin Connection Status

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

Annotations already indicate readOnlyHint, idempotentHint, and no destructive hint. The description adds context that the tool doesn't call Garmin or expose secrets, and lists the specific components checked, providing behavioral transparency beyond the annotations.

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 that efficiently conveys the tool's purpose and key constraints. No unnecessary words, and the information is front-loaded.

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?

While the description explains what is checked, it fails to document the two optional parameters (client, response_format) and does not describe the return value or output schema. Given the output schema exists, the description should at least hint at the response structure. This incompleteness reduces the tool's usability for an AI agent.

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?

Schema description coverage is 0%, meaning no parameter descriptions exist in the schema. The description does not explain what the 'client' or 'response_format' parameters do or how they affect the result. This leaves the agent without guidance on parameter usage.

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 the tool checks local Garmin config, token file, Node version, privacy mode, cache readiness, and optional MCP client readiness without calling Garmin or exposing secrets. It uses specific verbs and resources, distinguishing it from sibling tools that fetch remote data (e.g., garmin_capabilities, garmin_cache_status).

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 the tool is a safe local check, usable at any time, and contrasts with siblings that make remote calls. However, it does not explicitly state when to use this tool versus alternatives like garmin_cache_status or garmin_auth_instructions, or provide scenarios where it's not appropriate.

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