registry_get_usb_history

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

With no annotations, the description carries the full burden of behavioral disclosure. It adds a useful nuance about first_connected being the legacy last-write timestamp, but does not explicitly state read-only behavior, permissions, error conditions, or what happens if the hive is invalid. 'Get' suggests a read, but this is not made explicit.

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 consists of two clean sentences. The first sentence is the front-loaded purpose; the second adds a specific, non-redundant detail. No wasted 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?

For a tool with no output schema and no annotations, the description is too thin. It does not describe the returned structure (e.g., list of objects with device identity, WPD name, timestamps), nor does it provide usage context or typical pitfalls. An agent would need to call it or rely on external knowledge to understand the result.

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 schema has 0% description coverage, so the description must compensate. It does clarify that system_hive refers to the SYSTEM hive and ties the output to USBSTOR/WPD data, but it does not specify the expected format (path, filename, mounted hive) or constraints. Partial value is added beyond the raw schema.

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 a specific verb and resource: 'Get USBSTOR device identities and WPD names from SYSTEM hive.' This is distinct enough that an agent can tell it apart from generic registry query tools, though it does not explicitly compare with siblings like registry_query or registry_get_key.

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 guidance on when to use this tool versus the many available registry/forensic alternatives. The name implies a USB-history use case, but the description does not state a scenario or exclusion, leaving the agent to infer applicability.

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