move_items_to_bin

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'move items to bin', which is a terse statement of intent. It does not mention side effects (e.g., whether the move is destructive to original positioning, whether a specific bin is always used, permissions, or return values). The word 'expanded' hints at additional behavior but is not specific.

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, concise sentence. It front-loads the key action ('move items to bin') with no wasted words. However, its brevity borders on under-specification; while concise, it leaves out important context, so it earns a slight penalty for not earning its place in terms of substance.

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 no annotations, no output schema, and a very minimal input schema, the description is the sole source of information. It fails to clarify scope (which bin, which items), prerequisites, or any behavioral nuances. The existence of a very similar sibling tool ('move_item_to_bin') increases the need for differentiation, which is absent. The description is incomplete for the agent to use confidently.

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 input schema has zero parameters and the description adds no parameter-level detail. Since schema coverage is trivially high (100% because no params), the baseline is 3. The description does not clarify whether an implicit item selection is used or if the operation affects all items, but no params exist to elaborate.

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 states the verb 'move' and resource 'items' to 'bin', making the purpose clear. It distinguishes from 'move_item_to_bin' by implying multiple items, though it does not explicitly say 'multiple' or specify which items (selected, all, etc.). The phrase 'expanded operation' is vague but does not mislead.

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 vs. alternatives. The sibling 'move_item_to_bin' could be a candidate, but no exclusions or context are given. The description only states what the tool does, not when or why to choose it.

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