get_factory_coverage

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

Annotations already declare readOnlyHint=true and destructiveHint=false, covering safety. The description adds behavioral context beyond annotations by specifying the scope of the comparison (top-level Live factory browser devices) and the limitation (reports only missing profiles, not deep integration or all presets/Packs/plugins). This accurately sets expectations about what the tool does and does not verify.

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 with no filler. The first sentence front-loads the primary action and target, and the second sentence concisely states limitations. Every word contributes to clarity.

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 zero-parameter read-only tool with no output schema, the description adequately explains what the tool reports (missing profiles) and its boundaries. It could specify the exact shape of the report or how 'observed' devices are sourced, but given the tool's simplicity and the safety annotations, the description is sufficiently complete for an agent to invoke it 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?

The tool has zero parameters and the schema coverage is 100%, so there are no parameter semantics to clarify. The baseline for 0 params is 4. The description does not need to compensate for any parameter documentation gaps.

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 states a specific verb ('Compare') and resource ('observed top-level Live factory browser devices' against 'knowledge profiles'), and defines the output ('Reports missing profiles'). It also distinguishes itself from sibling tools by explicitly stating what it does not cover: 'not verified deep integration or all presets/Packs/plugins.' This makes the tool's role unambiguous.

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 gives clear context for when the tool is appropriate: when you need a coverage comparison report of observed factory devices against knowledge profiles. It explicitly states exclusions ('not verified deep integration or all presets/Packs/plugins'), which signals when NOT to use it. However, it does not name an alternative tool or provide an explicit 'use X instead' pointer, so it stops short of full routing guidance.

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