A4/5.0
Behavior3/5

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

With no annotations provided, the description carries the behavioral disclosure burden. It does state that no full binary is loaded and that bytes are converted into assembly instructions, but it does not explicitly disclose read-only behavior, output format details, or error handling for invalid hex input.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that is front-loaded with the core verb and resource, with no filler or redundant restatement. Every word contributes to understanding the tool's function.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with a fully documented input schema and a clear one-line functional statement, the description is largely complete. It lacks explicit output schema or return-value details, but the phrase 'into assembly instructions' conveys the expected result well enough for an agent to invoke and interpret the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the parameters are already fully documented in the input schema. The description adds minimal semantic value beyond the schema, only framing the operation as acting on raw bytes, which aligns with hex_bytes.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Disassemble') with a clear resource ('raw bytes') and output ('assembly instructions'). The phrase 'without loading a full binary' distinguishes it from sibling tools like disassemble and analyze_binary, making the purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Clearly conveys the intended context: use for raw bytes that are not part of a loaded binary. It does not explicitly name an alternative tool or state when not to use it, but the 'without loading a full binary' qualifier provides clear situational guidance.

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