passgage_create_user_shift

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, but it only restates the tool's name. It does not mention auth requirements, side effects, idempotency, or response format, leaving the agent uninformed about the operation's behavior.

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 extremely concise, consisting of a single short sentence with no redundant words. However, its brevity comes at the cost of omitting crucial contextual information, so it is concise but overly sparse.

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 (an open 'data' object with additionalProperties true), the absence of an output schema, and the large set of sibling tools, the description is severely incomplete. It does not explain what a user_shift is, what fields to provide, or what to expect in response.

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 a single 'data' parameter described as 'The data for creating the user_shift', and schema coverage is 100%. The description adds no additional parameter details, so it meets the baseline for high schema coverage but does not enhance understanding of the data object's structure.

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 ('Create') and the resource ('user_shift'), making the tool's purpose immediately clear. However, it does not elaborate on what a user_shift is or how it differs from related tools beyond the name, so it stops short of a 5.

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 the many sibling create/update tools, nor does it mention prerequisites or related operations like assign_user_to_shift. There is no context for when this is the appropriate choice.

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