dbgprobe.svd.describe

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

No annotations are provided, so the description must disclose behavior. It mentions the included information (description, access type, reset value, enum values) which implies a read-only operation. However, it does not explicitly state that it is non-destructive or whether it requires any special permissions. The behavioral traits are partially transparent.

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, well-formed sentence that captures the essential purpose without any superfluous words. It is front-loaded and efficient.

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 that there is no output schema, the description should ideally provide more context about the return format or structure. While it lists what the description includes, it does not mention whether it returns a JSON object or text, or how detailed the description is. For a tool that provides detailed information, the missing output schema makes the description somewhat incomplete.

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 only 50%: the 'target' parameter has a description, but 'session_id' has none. The tool description does not add any additional meaning for 'session_id', leaving its purpose unclear. It slightly compensates for 'target' by confirming the pattern, but overall fails to fully explain the parameters.

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 verb 'Describe' and the resource: peripheral, register, or field. It distinguishes from sibling tools like list_peripherals (which only enumerates) and read (which reads current value) by specifying the inclusion of access type, reset value, and enum values.

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 explicit guidance on when to use this tool versus alternatives. For example, it does not say 'Use this to get a detailed description instead of using list for names or read for actual values.' The context signals and sibling tools show many related SVD tools, but the description provides no usage context.

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