registry_get_key

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

With no annotations provided, the description is the sole source of behavioral context. It only says 'get', implying read-only, but does not clarify if it modifies the hive, requires special permissions, or how values are returned. The description is too brief to disclose important traits.

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?

Single sentence, but it is concise. However, it lacks structure and could be expanded to include parameter details or usage notes without being verbose.

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 3 parameters, no output schema, and many sibling tools performing similar registry operations, the description is too sparse. It does not explain the return format, depth parameter behavior, or how values are presented, leaving significant gaps.

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, and the tool description adds no explanation of parameters (hive_path, key_path, max_depth). The name 'max_depth' is the only hint of functionality. The description fails to compensate for the poor schema documentation.

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?

Description states 'Get registry key and values from a hive file', which clearly indicates the action and resource. However, it does not differentiate from sibling tools like registry_search or registry_get_network, which also deal with registry keys.

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 on when to use this tool versus alternatives such as registry_search or registry_get_persistence. There is no mention of prerequisites or context where this tool is appropriate.

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