create_identity_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. It identifies the operation as a create, but it does not mention the confirm flag required to execute the write, the agentReason requirement, whether existing data is affected, or what the operation returns.

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, front-loaded sentence with no filler. It communicates the core action, source, and target efficiently, though it omits useful behavioral context that could be included without much extra length.

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 has five parameters, a large nested template object, no output schema, and no annotations, the one-line description is materially incomplete. An agent is left without guidance on the required confirm behavior, how to choose between vaultName and shareId, or whether agentReason is needed in agent contexts.

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 schema has 100% description coverage for the five top-level parameters, including the template payload and target vault/share. The description adds the context that the item is created 'from template payload in a vault or share', but it does not explain the relationship between vaultName and shareId or the confirm requirement beyond what the schema already states.

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 a specific verb ('Create') and resource ('identity item') and clarifies it uses a 'template payload' with a target of 'vault or share'. This clearly distinguishes it from sibling tools like create_note_item or create_wifi_item, although it does not explicitly name any sibling it is not.

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 given on when to choose this tool over alternatives such as create_custom_item or create_login_item_from_template. The description implies it is for identity items, but it does not state when this is the appropriate choice or mention any exclusions.

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