Create one native GenAds project linked to this parent

native.create_genads_project
DestructiveIdempotent

Create one native GenAds project linked to this parent. It is supporting creative work, never a Series episode or a paid campaign.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

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.

B3.1/5.0
Behavior2/5

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

Annotations already declare destructiveHint=true, openWorldHint=true and idempotentHint=true, so the safety and repeat-safety profile is covered. The description adds essentially no behavioral context beyond the parent linkage: nothing about the request_key idempotency contract, what the new project inherits from the parent, or what side effects occur. Only 'linked to this parent' is new information.

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

Conciseness4/5

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

Two short, front-loaded sentences with the action stated first and the exclusion second; nothing is padded. Its brevity is close to under-specification rather than verbosity, so it scores well on structure but not perfectly.

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?

For a six-parameter creation tool with a nested brief object, five required inputs and catalog-version/skill-proof preconditions, the description is far too thin. An output schema exists so return values needn't be explained, but the call preconditions and the meaning of the mandatory proof parameters are missing entirely.

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 only 50% across six parameters, including a deep nested 'arguments.brief' object with objective/platform enums and URL constraints. The description mentions no parameter at all — no guidance on work_id, the required read_skills proofs, or expected_catalog_version — so it fails to compensate for the coverage gap.

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?

The description uses a specific verb plus resource ('Create one Creative project') and scopes it with 'linked to this parent'. It also rules out two confusable objects ('never a Series episode or a paid campaign'), which separates it from create_series_project and the genads campaign tools, though it never names those siblings directly.

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?

It supplies explicit when-not conditions (not a Series episode, not a paid campaign), which is real routing signal for an agent scanning many create_* siblings. It stops short of naming the alternative tool to use in those cases, and gives no prerequisites such as needing a prior session bootstrap or catalog version.

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