Create On Call Shadow

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, so the mutation profile is covered. The description adds nothing beyond the verb, not explaining what a shadow configuration is, whether the schedule must exist, or any side effects of creating one.

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 repetition. However, "from provided data" is effectively filler and the extreme brevity leaves important context unstated.

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 create mutation with a required nested data object and schedule_id, the description does not explain required inputs, the meaning of shadowable_type, or expected effects. An output schema exists, so return values need not be described, but the creation context is substantially incomplete.

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 coverage is roughly 50%, with descriptions for schedule_id and most nested shadow attributes. The description adds no meaning beyond the schema and does not explain the nested data envelope or the shadowable_type/shadowable_id relationship, so it neither compensates for gaps nor harms 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 states a specific verb ("Creates") and resource ("on call shadow configuration"), so an agent can identify the operation. It does not explicitly distinguish itself from sibling create/update/list shadow tools, but the create intent is clear.

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?

There is no guidance on when to use this tool, what prerequisites are required, or how it differs from alternatives such as update_on_call_shadow or list_on_call_shadows. The only clue is the verb "Creates", leaving usage context entirely implicit.

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