v0.1.3Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must convey behavioral traits. It implies a read-only operation but does not explicitly state side effects, permissions, or rate limits. The lack of behavioral detail is a gap.
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 clear sentence with no fluff. Each word contributes meaning. However, it lacks structure (e.g., bullet points or sections) which could improve scanability.
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 no output schema, the description partially explains return values by listing examples, but it is not exhaustive and does not clarify terms like 'primary tracker role'. The tool is simple (0 params), so the depth is moderate but could be more 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?
There are 0 parameters, and schema coverage is 100%. The description adds value by enumerating the fields returned (firmware version, update availability, etc.), which goes beyond the empty schema. With no parameters, baseline is 4, and the description provides meaningful 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 the tool retrieves connected device information and lists specific fields (firmware version, update availability, etc.). It is a specific verb ('Get') and resource ('connected device information'), but it does not explicitly differentiate from siblings, though no sibling appears to overlap.
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?
No guidance on when to use this tool versus alternatives (e.g., garmin_health, garmin_gear). No context about prerequisites or exclusions. The description merely states what it returns without usage direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
