binary.segments

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

No annotations are present, so the description must fully disclose behavior. It only mentions 'list' (implying a read operation) but omits details like default pagination limits, ordering, error handling, or whether the session_id must correspond to an open binary. This is insufficient for a reliable tool invocation.

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 extremely short (two words plus a prepositional phrase), but it sacrifices essential information. Conciseness should not come at the cost of completeness; missing parameter explanations and usage context make this under-specified rather than concise.

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 absence of an output schema, annotations, and any parameter descriptions, the tool definition is critically incomplete. The agent lacks information about return format, pagination behavior, error conditions, and the nature of 'segments,' making it nearly impossible to use correctly without prior domain knowledge.

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%, meaning the description must compensate. It does not mention any of the three parameters (limit, offset, session_id) or explain their roles. The agent must infer from parameter names alone, which is inadequate for correct usage.

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 explicitly states 'List segments with pagination,' which clearly identifies the action (list) and resource (segments). However, it does not differentiate from similar sibling tools like binary.sections or binary.symbols, which also list parts of a binary.

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 guidance is provided on when to use this tool versus alternatives. With many sibling list tools (e.g., binary.sections, binary.functions), the agent receives no hints about prerequisites, exclusions, or preferred scenarios.

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