devicelens_capture_snapshot

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

The description clarifies that the tool is non-destructive to devices/drivers, which is valuable beyond annotations (destructiveHint false). However, it omits potential side effects like disk usage from saving snapshots. Consistent with annotations, no contradiction.

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, efficient sentence that front-loads the core purpose and safety note. No extraneous words.

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?

The tool is simple with one optional parameter and an output schema (not shown). The description covers purpose and safety but lacks explanation of the label parameter and return value context. Adequate but not thorough.

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 optional 'label' parameter. The description adds no meaning about its purpose, format, or effect. Baseline without schema coverage is 4, but the description fails to compensate, hence 2.

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 action ('Save a local DeviceLens inventory snapshot') and distinguishes it from sibling tools by emphasizing safety ('never changes Windows devices or drivers'). This provides a specific verb and resource with 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?

The description implies safety but does not explicitly state when to use this tool versus alternatives like devicelens_list_snapshots or devicelens_check_driver_updates. No guidance on prerequisites or context.

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