get_device_knowledge

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds that results include retained findings plus recent experiment history, which is useful content disclosure, but it does not say how "recent" is bounded, whether results are truncated, or what happens for an unknown device.

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 compact sentence with no filler, front-loaded with the verb. It is slightly compressed to the point of ambiguity ("all" discoveries vs "recent" history), but nothing is wasted.

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 explained, and annotations cover safety. Still, for a read tool with one undocumented parameter, the description leaves gaps around scope, recency bounds, and behavior on invalid device IDs.

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% for the single required device_id, and the description never mentions it. It does not clarify whether the ID must be a previously discovered/paired device or what format is expected, so the description fails to compensate for the documentation 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?

The description names a verb ("Read") and a resource, but the resource is expressed in internal jargon ("retained discoveries", "communication experiment history") that an agent cannot map onto concrete data without prior knowledge of this server. It also gives no signal distinguishing it from siblings like get_device_events or inspect_device, which sound related.

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?

There is no statement of when to call this versus alternatives such as inspect_device, get_device_events, or list_known_devices, and no prerequisites or exclusions. An agent must guess based on the name alone.

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