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

Annotations already declare destructiveHint=true and readOnlyHint=false. The description adds the key nuance that this is a soft-delete (not a permanent delete) and that the item will no longer appear in list_shopping_list_items. This goes beyond the annotations by specifying the nature of the deletion and its visibility impact.

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?

Two sentences, front-loaded with the action verb, and no redundant information. Every clause contributes meaning: the action, the nuance (not bought), the soft-delete nature, and the effect on list display.

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?

The tool is simple (single parameter, output schema exists, annotations provide safety profile). The description explains the outcome well (item disappears from list) and the soft-delete nuance. It does not cover error cases or reversibility, but given the low complexity, 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?

Schema coverage is 100%, and the parameter description fully explains the id field, including its provenance (returned by add/batch_add/list). The description adds no additional parameter meaning beyond the schema, so baseline 3 is appropriate.

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 clearly states the action ('Remove an item') and identifies the resource ('the household's shopping list'). It explicitly contrasts with 'without marking it as bought', distinguishing it from buy_shopping_list_item and update_shopping_list_item. This is a specific verb+resource with scope.

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 phrase 'without marking it as bought' implicitly indicates when to use this tool versus the buy alternative, and 'soft-deletes' implies it's for removal rather than completion. It doesn't explicitly name sibling tools or provide exclusions, but the context is clear enough for an agent to select it appropriately.

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