export_device_profile

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and closed-world scope, so safety is covered. The description adds that output is serialized JSON text suited to backup/sharing, which is genuine extra context, but it says nothing about permissions, whether the device must be known/paired, or size limits of the export.

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?

A single twelve-word sentence that front-loads the verb and resource with zero wasted phrasing. The format and use case follow immediately with no filler.

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?

An output schema exists, so return values need not be described, and annotations cover the safety profile. For a one-parameter read-only export, the main remaining gap is device identifier provenance, which is a moderate but not severe omission.

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?

The single parameter device_id has 0% schema description coverage and the description never mentions it, so nothing clarifies what identifier form is expected or whether the device must first appear in list_known_devices. The description entirely fails to compensate for the coverage gap.

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?

States a specific verb (export), resource (device profile), and output format (JSON text), which distinguishes it from read-oriented siblings like inspect_device or get_device_knowledge. It does not explicitly name which sibling to use instead, so it falls short of full sibling differentiation.

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?

"for backup or sharing" implies the scenario in which to use this tool, but there is no explicit when-not guidance and no named alternative (e.g., inspect_device for read-only viewing, update_device_profile for the inverse operation). Usage must be inferred from the stated intent.

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