Samsung Health Quickstart

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

Annotations declare readOnlyHint, idempotentHint, and not destructive. The description adds valuable context: it adapts to current state (checking env variables and file existence) and is local-first, never touching external APIs. This goes beyond 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 two sentences, each earning its place: first defines tool purpose, second adds usage guidance and behavioral context. No unnecessary words.

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?

For a simple tool with one optional parameter and no output schema, the description covers purpose, usage, and behavioral traits adequately. Minor gap: the output format (markdown vs json) is implied via the parameter but not described.

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 coverage is 0% and the description does not explain the only parameter (response_format enum). The parameter is optional with a default, but its role in controlling output format is not mentioned, leaving the agent without needed context.

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 'personalized 3-step setup walkthrough' and identifies the specific use case: 'Call this first when the user asks how do I connect Samsung Health?' It distinguishes itself from sibling tools by being the initial onboarding step.

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 explicitly says when to use it ('when the user asks how do I connect Samsung Health?') and implies it's the first step. However, it does not provide explicit when-not-to-use guidance or mention alternative sibling tools.

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