create_creative_version

Idempotent

create creative version. Classification: writes to Studio. Execution: synchronous. Task support: forbidden. Mutation modes: validate_only, preview_only, execute. Partial failure policy: completed_items_not_rolled_back. The returned JSON is internal application state for LeanrIQ and ChatGPT orchestration. Use assistantSummary first when responding to the user. Never display raw JSON, data, or meta unless the user explicitly asks for raw JSON. Mention IDs only when useful for follow-up or debugging. Prefer concise, human language, highlight the most useful insight, and suggest the next best LeanrIQ action. If idempotencyKey is omitted on a mutation, the MCP layer derives a deterministic retry key from the tool and business arguments so an accidental identical replay cannot create duplicate work. For a mutation when more than one seat is authorised, seatId or seatName must be supplied on that exact tool call; a remembered or previously selected seat is not sufficient for a write.

B3.3/5.0

Behavior5/5

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

Beyond the annotations (readOnlyHint=false, idempotentHint=true, destructiveHint=false), the description adds substantial behavioral context: synchronous execution, task support forbidden, the completed_items_not_rolled_back partial-failure policy for multi-item writes, and the deterministic retry-key derivation when idempotencyKey is omitted. The seat-binding rule (a remembered seat is insufficient for a write) is exactly the kind of precondition an agent must know before calling.

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

Conciseness3/5

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

The opening is front-loaded with the useful mutation facts, but a large block is generic response-formatting boilerplate ("Use assistantSummary first... Never display raw JSON... suggest the next best LeanrIQ action") that applies to every tool and dilutes this one. The redundant "create creative version." lead-in also costs a sentence.

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

Completeness3/5

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

With an output schema present, return values need no explanation, and the description covers the mutation contract, idempotency, and seat requirement well. However, for a 23-parameter nested write with 0% schema description coverage, the near-total silence on parameter meaning leaves the definition incomplete for correct invocation.

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 0% across 23 parameters, so the description carries the full burden — and it only explains idempotencyKey and seatId/seatName semantics. Nothing is said about creative, approvalId, expectedVersion, dryRun, or the many locale/market parameters, leaving most inputs undocumented.

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

Purpose3/5

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

"create creative version" essentially restates the tool name and title, though "Classification: writes to Studio" adds that it is a write in the Studio domain. It does not distinguish this from near siblings such as clone_creative, revise_creative, or restore_creative_version, so an agent gets no help disambiguating the version-creation family.

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

Usage Guidelines3/5

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

It discloses the valid mutation modes (validate_only, preview_only, execute) and a real precondition: when multiple seats are authorised, seatId/seatName must be supplied on the exact call. That is useful operational guidance, but there is no statement of when to reach for this tool over clone_creative / revise_creative, and no explicit exclusions.

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