Duplicate project

duplicate_project

Clone an entire project — every clip, voiceover, asset, and metadata field — into a fresh project. The copy has its own S3 namespace, so changes or deletions to the source never affect the duplicate.

Defaults:

  • new_title omitted → "{source title} (copy)" when no folder_id is given (or it's empty) and the source stays in the same org; pass an explicit non-empty folder_id and the title is preserved.

  • folder_id omitted → copy lives in the same folder as the source.

Returns the new project's id and title. Concurrency: whole-project read+create — serialize against other mutations on the same source_project_id; do not run them in parallel.

folder_idNoPlace the duplicate in this folder. Omit to keep the same folder as the source. Pass '' (empty string) to move to workspace root.

TDQS

A4.7/5.0
Behavior5/5

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

Beyond the annotations (readOnlyHint=false, destructiveHint=false), the description discloses the key behavioral trait that the duplicate has its own S3 namespace and is therefore independent of the source. It also states return values and warns about concurrency, which is exactly the kind of context an agent needs.

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?

The description is compact, front-loaded with the core purpose, and uses a short bulleted 'Defaults' section to organize conditional behaviors. The concurrency warning is a single necessary sentence. No filler or redundancy.

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

Completeness5/5

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

For a tool with no output schema, the description correctly states what is returned (new project's id and title). It covers source selection, folder targeting, title defaults, copy independence, and concurrency safety, leaving no crucial operational gap for invoking the tool correctly.

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

Parameters4/5

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

The schema covers 100% of parameters, so a baseline of 3 applies. The description adds meaningful nuance beyond the schema: the conditional title behavior when new_title is omitted, the distinction between omitting folder_id and passing an empty string, and the effect of an explicit non-empty folder_id.

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

Purpose5/5

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

The description opens with a specific verb and resource — 'Clone an entire project' — and enumerates what is copied: every clip, voiceover, asset, and metadata field. It clearly differentiates from the sibling duplicate_clip by emphasizing the whole-project scope.

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

Usage Guidelines4/5

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

The description gives clear operational guidance: default title behavior, folder placement behavior, and an explicit concurrency constraint to serialize against other mutations on the same source_project_id. It does not explicitly name alternatives like create_project or duplicate_clip, but the scope statement makes the intended use apparent.

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