registry_get_usb_history

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

The description only states the action (get USB history) and source (SYSTEM hive). With no annotations, the description should disclose behavioral traits like whether it's read-only, any side effects, or output format. It fails to provide such context.

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 sentence with no unnecessary words. However, it is too terse for the tool's complexity, omitting critical details that would justify a higher score.

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 tool has one required parameter, no annotations, and no output schema, the description is severely incomplete. It does not describe the output format, behavior, or usage context, making it nearly useless for an AI agent.

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 input schema has 0% description coverage for the single required parameter 'system_hive'. The description does not explain that this parameter expects a path to the SYSTEM registry hive file, leaving the agent without semantic understanding.

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 tool retrieves USB device history specifically from the SYSTEM hive, using a specific verb and resource. This distinguishes it from sibling registry tools like registry_get_key or registry_get_system_info, which focus on different registry data.

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 alternatives. There is no mention of prerequisites, context, or exclusions, leaving the agent without decision support for tool selection.

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