get_binary_info

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

With no annotations provided, the description carries the full burden. It correctly implies a read-only, non-destructive operation ('Get metadata'), but does not explicitly state safety, performance characteristics, or that it always reflects the current state of the binary. The lack of explicit assurance is a minor gap.

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-front-loaded sentence. Every word adds meaning, with no redundancy or unnecessary detail. It efficiently conveys the tool's purpose and return data.

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 the tool has no parameters and an output schema exists, the description fully covers what is needed: it states the action and the returned information. For a zero-parameter tool, this is sufficiently complete.

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?

There are zero parameters, and the schema coverage is 100% (empty schema). Per guidelines, baseline is 4. The description adds value by enumerating the metadata fields, giving the agent a precise expectation of what the tool provides.

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 ('Get metadata') and clearly identifies the resource ('currently loaded binary'), listing the exact pieces of information returned (filename, architecture, bitness, entry point). This distinguishes it from sibling tools that focus on specific parts of the binary (e.g., get_function_info, list_segments).

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 states what the tool returns but provides no guidance on when to use it versus alternatives. It does not mention scenarios where other tools (like list_functions or get_bytes) would be more appropriate, nor does it exclude misuse cases.

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