get_bin_data_tool

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

Description discloses return format and config dependency (basic vs enhanced). However, no annotations are present, and the description does not cover error behavior, side effects, or permissions, which are important for a data retrieval tool.

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?

Extremely concise with two clear sections (Args, Returns). No wasteful words, highly structured.

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?

For a simple one-parameter, no-output-schema tool, the description covers basic functionality and return type. Lacks error handling details, but overall sufficient for its complexity.

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 provides only parameter name and type (0% coverage). Description adds meaning by explaining 'bin' is the BIN number to query, which compensates for the lack of schema descriptions.

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?

Clear verb 'Get' and resource 'BIN data' stated explicitly. Distinguishes itself from potential siblings by specifying it operates on a BIN number.

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 on when to use this tool or when alternatives might be better. Since no siblings exist, it still lacks contextual usage hints.

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