Duplicate Study

duplicate_study

Permanently copy a Study with its questions and results over the same Audiences.

Input Schema

Name	Required	Description
`name`	No	Name of the copy. Defaults to "<name> (copy)".
`studyId`	Yes	Study to duplicate; you must be able to open it. The private copy keeps every answer, chart, heatmap, summary and finished run; a schedule is copied paused. Audiences are shared, not copied (use duplicate_audience). Refused while a run is live.
`idempotencyKey`	No	Retry key. Without one, an identical call within 15 minutes returns the same copy instead of a second one; send a new key only to deliberately make another copy of the same source with the same name.

Output Schema

Name	Required	Description
`data`	No	The new Study: id, name, createdAt and its Audiences with their Minds.
`workspaceUrl`	No	Minds workspace link for the new Study.
`idempotencyKey`	No	Key of this duplication; reuse it to retry without creating a second copy.

B3.4/5.0

Behavior3/5

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

The description adds useful behavioral context beyond annotations: the copy is permanent, includes questions and results, and keeps the same Audiences. However, it omits permissions, run-state restrictions, and idempotency behavior, which are covered only in the schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence communicates the core operation with no filler. It is appropriately compact and easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The definition is reasonably complete given the rich schema and output schema. Minor behavioral details such as live-run refusal and idempotency defaults live in the schema rather than the description, but the core operation is clear.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all three parameters are already documented in the input schema. The description does not add parameter-level meaning beyond what the schema provides, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: copying a Study, including questions, results, and the same Audiences. It is clear what the tool does, but it does not explicitly differentiate itself from sibling creation or duplication tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit guidance on when to use this tool versus create_study, duplicate_audience, or other study tools. The purpose implies duplication, but no alternatives, prerequisites, or exclusions are stated in the description.

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