delete_item

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

With no annotations provided, the description carries the full burden of behavioral disclosure. While it mentions the destructive nature ('Delete') and error conditions, it doesn't address critical aspects like whether deletion is permanent, what permissions are required, rate limits, or side effects on related data. The 'Raises' section adds some value but doesn't fully compensate for the lack of annotations.

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 well-structured with clear sections (Args, Returns, Raises) and uses minimal words to convey essential information. Every sentence earns its place, though the core 'Delete an item' could be slightly more specific about what 'item' refers to in this context.

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 this is a destructive operation with no annotations, 0% schema coverage, but with an output schema (implied by 'Returns'), the description is moderately complete. It covers the basic operation, parameter, return value, and one error case, but lacks details on permissions, reversibility, and broader error handling that would be crucial for safe agent use.

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%, so the description must compensate. It provides the parameter name and clarifies it's 'The unique identifier of the item to delete,' which adds meaningful context beyond the bare schema. However, it doesn't specify format requirements (UUID, integer, etc.) or validation rules, leaving gaps in parameter understanding.

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 verb ('Delete') and resource ('an item'), making the purpose immediately understandable. However, it doesn't differentiate this destructive operation from its sibling 'update_item' which also modifies items, or explain what type of 'item' is being deleted (database record, file, etc.).

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 description provides no guidance on when to use this tool versus alternatives like 'update_item' for modification or 'create_item' for recreation. It mentions raising ValueError if the item is not found, but doesn't specify prerequisites like authentication needs or whether deletion is reversible.

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