update_item

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

No annotations are present, so the description must disclose behavioral traits. It states 'Update an item's fields' but does not specify whether updates are overwrites or merges, what happens to unspecified fields, or any permission requirements. The parameter list is misleading as it suggests separate parameters when the schema has only three.

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 long, code-style parameter listing that is not concise. It could be shortened and restructured to highlight key points first.

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 the tool's complexity with many fields in an object, the description is incomplete. It does not explain the 'fields' object structure, nor does it mention the output schema content. The description could help by clarifying the parameter hierarchy.

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 0% description coverage. The description adds a list of field names (title, status, etc.) that are presumably inside the 'fields' object, providing some meaning beyond the bare schema. However, the structure of 'fields' is not explained, leaving ambiguity.

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 tool name 'update_item' with description 'Update an item's fields' clearly indicates the action and resource. However, it does not differentiate from sibling tools like 'move_item' or 'create_item', which could be confused.

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 on when to use this tool versus alternatives. The description does not mention context, prerequisites, or typical use cases.

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