read_registers

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

With no annotations, the description carries the burden of conveying that this is a read-only operation and that the default is all general-purpose registers. However, it does not disclose session_id behavior, what happens if the target is not stopped, or how results are returned.

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?

A single concise sentence front-loads the action and puts the default/subset distinction in a parenthetical. No filler or redundant restatement.

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 definition is usable for a simple read operation, but it lacks any guidance on session selection and does not describe the output shape despite no output schema being present. The missing session_id semantics create a real completeness gap.

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 0%, so the description must explain parameters. It hints at the 'names' parameter with 'named subset' but never mentions session_id at all, nor the format or effect of the names values.

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 uses a specific verb and resource ('Read register values') and adds scope: all general-purpose registers by default or a named subset. This makes it clearly distinct from sibling tools like read_memory or write_register.

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 description implies the tool is for reading register values and contrasts with write_register by saying 'read', but it never explicitly states when to choose this over alternatives or mentions any exclusions. Usage context must be inferred.

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