Input Schema

NameRequiredDescriptionDefault
work_idYes
argumentsYes
read_skillsYesExact required native skills and their dependencies, copied from the accepted session bootstrap's skills array. Include only entries in that array. General mcp.* guides and native.{studio}.instructions are guidance, not native skill proofs.
request_keyYes
publication_proposal_idNoFor native Social scheduling, the exact server-approved publication proposal. This identifier cannot confer approval by itself.
expected_catalog_versionYesFor a new session, read a studios/{studio}/native/{pack} child toolset and copy invocation.catalog_version from a native tool descriptor. Do not use the top-level library version. For calls in an existing session, use that session proposal's catalog_version.

B3.2/5.0
Behavior2/5

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

Annotations already flag destructiveHint=true, idempotentHint=true and openWorldHint=true, but the description adds no behavioral context beyond that — it does not say what the folder creation affects, that it is a workspace-mutating write, or that read_skills and expected_catalog_version proofs are required. For a destructive, open-world mutation, remaining silent on these traits leaves the agent under-informed.

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?

One sentence with the positive case first and the disambiguation second; there is no filler and nothing is buried.

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

Completeness2/5

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

Five required parameters including a nested object, a session-proof array, and a catalog version, on a destructive open-world mutation, need far more than one sentence. The output schema exists so return values need not be described, but invocation preconditions and the meaning of the nested arguments are missing.

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

Parameters2/5

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

Schema description coverage is 50% and the description mentions none of the six parameters. The nested 'arguments.name' and 'season_number' properties, and why a folder would carry a season number, are left entirely unexplained, as are request_key idempotency and work_id scoping.

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 ('Create an organizational MOVIE PROJECT folder') and explicitly names the sibling that handles the other case (create_document_folder), so an agent can separate the two folder-creation tools. It does not distinguish itself from other folder-like siblings such as native.create_element_folder, which keeps it from a 5.

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 clause 'document folders use create_document_folder' gives a clear alternative and the condition that routes to it. It gives no guidance on prerequisites (session bootstrap skills, catalog version) or when a folder should be created at all versus organizing existing work via native.organize_project.

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