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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the agent knows this is a safe read operation. The description adds the Base64 return format, which is useful, but it doesn't mention potential pitfalls like command validity or connection requirements. The added value beyond annotations is minimal.

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, 13 words, with no filler. It front-loads the action and resource, then states the output format. Every word earns its place.

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: one parameter, output schema exists, and annotations cover safety. The description explains the core purpose and return format. It lacks caveats like 'command must be valid SCPI' but those are common across sibling tools and not strictly necessary for this simple operation.

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 one parameter 'command' with no description, and the description gives minimal guidance by indicating it should be a 'documented binary-block query'. While this hints at the expected input, it doesn't provide examples or syntax details, leaving the parameter semantics under-specified.

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's function: running a binary-block query and returning bytes as Base64. It specifies the resource (binary-block query) and the output format, distinguishing it from query_scpi (which likely returns text) and write_binary (which writes 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?

The phrase 'documented binary-block query' sets clear context for when to use this tool: when you need to execute a query that returns binary data and you know a documented command. However, it does not explicitly mention alternatives or when not to use it, such as preferring query_scpi for text responses.

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