import_item

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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'import' implies a write operation, it doesn't specify whether this requires special permissions, what happens on duplicate items, whether the operation is idempotent, or what the response contains. The description mentions timestamp customization but doesn't explain behavioral implications of overriding system-generated timestamps.

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, efficient sentence that communicates the core functionality without any wasted words. It's appropriately sized and front-loaded with the essential information.

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 write operation with no annotations and no output schema, the description is insufficient. It doesn't explain what constitutes a successful import, what format the response takes, error conditions, or how this tool differs from similar creation operations. The context signals show this is a 6-parameter tool with complex nested structures (tags array with objects), but the description doesn't address these complexities.

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 description highlights the unique timestamp parameters (created_at/updated_at) which are indeed part of the schema. However, with 100% schema description coverage, the schema already documents all 6 parameters thoroughly. The description adds minimal value beyond what's in the schema, meeting the baseline for high coverage.

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 ('import') and resource ('item'), and specifies the unique capability of setting custom timestamps. However, it doesn't explicitly differentiate from the sibling 'create_item' tool, which appears to be a similar creation operation without timestamp customization.

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 'create_item' or other creation tools in the sibling list. There's no mention of prerequisites, typical use cases, or when this specific timestamp customization capability is appropriate.

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