get_insertion_bin

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

No annotations are provided, and the description does not disclose whether this is a read-only operation, what the return value is, or any side effects. The phrase 'expanded operation' is meaningless and adds no behavioral context.

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, but this is under-specification, not conciseness. The single sentence provides no value beyond restating the tool name, so it does not earn its place.

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 getter tool with no output schema and no annotations, the description should at least hint at the return type or purpose. It is completely inadequate, leaving the agent to guess what 'insertion bin' means and what data will be returned.

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?

The tool has zero parameters, so the schema has nothing to explain. Per the rubric, a baseline of 4 is appropriate since there is no missing parameter information. The description adds nothing about parameters, but no parameters exist.

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 repeats the tool name ('get insertion bin') with the generic qualifier 'expanded operation,' providing no additional context about what an insertion bin is or what the tool returns. It fails to distinguish itself from sibling tools like get_source_monitor_info or get_bin_contents. The intended resource is ambiguous.

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?

There is zero guidance on when to use this tool versus alternatives. No mention of prerequisites, context, or exclusions. Given the large sibling list, this absence is critical.

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