getDeviceNotes

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

No annotations are present, and the description contains no information about side effects, read-only nature, authentication requirements beyond listing the apiKey parameter, rate limits, or any other behavioral traits. The description carries the full burden but fails to address this.

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 very short (three lines of content), which is concise but at the expense of missing the core purpose. It includes a category line and parameter list, but every sentence should earn its place; here, the first line is just the name, which is redundant.

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 the complexity (simple tool with 3 parameters), no output schema, and no annotations, the description is incomplete. It does not mention what the tool returns (e.g., notes text), how to interpret the output, or any post-conditions. The tool is not fully documented for an agent to use correctly.

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 100% with detailed descriptions for all three parameters (host, name, apiKey). The description adds no additional meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 does not explicitly state the tool's purpose. It only repeats the tool name 'getDeviceNotes' and lists parameters, but fails to say that it retrieves notes for a device. Sibling tool names like 'getDeviceInfo' and 'getDeviceSummary' suggest a pattern, but the purpose is vague without an explicit statement.

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 is provided on when to use this tool versus its siblings (e.g., getDeviceInfo, getDeviceSummary). There are no mentions of prerequisites, exclusions, or when not to use it.

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