LeanrIQ

Create AI Display CreativeDocuments from objective and requestedFormats without pre-existing creatives. Optional outputs requests static JPEG/PNG delivery after save_to_studio while retaining the editable document. Export existing versions with export_creative. Build and save existing Studio creative records. When campaignId or campaignName is supplied, LeanrIQ resolves the complete persisted campaign inventory, uses each saved brief, approved asset set, and eligible global or advertiser template, then runs the canonical Studio Gold build path. Campaign-scoped calls save by default; use persistence preview_only only for an unsaved ad-hoc preview. (deprecated alias)

Create AI Display CreativeDocuments from objective and requestedFormats without pre-existing creatives. Optional outputs requests static JPEG/PNG delivery after save_to_studio while retaining the editable document. Export existing versions with export_creative. Build and save existing Studio creative records. When campaignId or campaignName is supplied, LeanrIQ resolves the complete persisted campaign inventory, uses each saved brief, approved asset set, and eligible global or advertiser template, then runs the canonical Studio Gold build path. Campaign-scoped calls save by default; use persistence preview_only only for an unsaved ad-hoc preview.. Deprecated alias for build_ad. Classification: creates billable AI usage. Execution: durable. Task support: optional. 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.

A3.7/5.0

Behavior5/5

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

Adds substantial context beyond the annotations: 'creates billable AI usage,' 'Execution: durable,' 'Mutation modes: validate_only, preview_only, execute,' and a partial-failure policy ('completed_items_not_rolled_back'). It also discloses that omitted idempotencyKey is derived deterministically and that seatId/seatName must be passed on the exact write call when multiple seats are authorized. This is exactly the extra behavioral burden the structured fields do not carry.

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?

Purpose is front-loaded and the operational notes are useful, but the opening sentences duplicate the title almost verbatim and the body is padded with boilerplate ('The returned JSON is internal application state...' 'Never display raw JSON...'). There is also a stray double period. Several sentences could be tightened without losing meaning.

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?

An output schema exists, so return-value explanation is unnecessary, and the description does cover persistence behavior, seat requirements, idempotency, and deprecation. However, for a 0-required, 40-parameter, 3%-coverage mutation tool, the description leaves too many inputs undefined to be considered complete.

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?

With 40 parameters and only 3% schema description coverage, the description must carry the semantics, and it only explains a fraction: objective, requestedFormats, persistence, outputs (static JPEG/PNG), campaignId/campaignName, seatId/seatName, idempotencyKey. Dozens of parameters (flightId, template, accountId, advertiser, instructions, targetMarket/locales, marketContext, etc.) remain undocumented in both the schema and the description.

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 AI Display CreativeDocuments from objective and requestedFormats') and explicitly names two siblings it is not: export_creative for existing versions, and build_ad ('Deprecated alias for build_ad'). That is enough to route an agent, though the surrounding text also claims 'Build and save existing Studio creative records,' which muddies the boundary between creating and rebuilding.

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?

Gives a clear precondition ('without pre-existing creatives'), an explicit alternative ('Export existing versions with export_creative'), and a when-not for the persistence mode ('use persistence preview_only only for an unsaved ad-hoc preview' vs campaign-scoped calls that 'save by default'). It stops short of plainly telling the agent to prefer build_ad over this deprecated alias, which is the most important routing decision here.

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