list_assets

Read-onlyIdempotent

list assets. Classification: read-only. Execution: synchronous. Task support: forbidden. 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. Studio assets are scoped resources: pass advertiserId or creativeId when listing assets, and pass one of those scopes together with assetId when retrieving one asset. LeanrIQ returns INVALID_INPUT rather than a misleading empty result when that scope is absent.

B3.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, and the description correctly reinforces that with 'Classification: read-only'. It then goes beyond the structured data by disclosing synchronous execution, 'Task support: forbidden', and the INVALID_INPUT failure mode instead of a misleading empty result — genuine behavioral context an agent could not infer otherwise.

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 content is dense but mixes three concerns — tool metadata, response-presentation rules ('never display raw JSON', 'use assistantSummary first'), and parameter scoping — without clear hierarchy. The presentation guidance is lengthy relative to the thin purpose statement, which is not front-loaded.

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 values need not be described, and the orchestration/presentation guidance is appropriate for an agent-facing API. But the description leaves the 21 filter/pagination parameters essentially unexplained and references an assetId parameter that the schema does not define.

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?

There are 21 parameters with 0% schema description coverage, so the description carries the full burden and largely fails: only advertiserId, creativeId, and assetId are discussed. Worse, assetId does not appear in the input schema at all, which could mislead an agent, while limit, cursor, status, seatId, accountId, campaignId, and all the locale/market fields are never explained.

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?

The description opens with the near-tautological 'list assets', so the core purpose rests almost entirely on the title. It does add scope detail ('Studio assets are scoped resources') that hints at what kind of assets these are, but it never distinguishes this tool from siblings like get_asset, list_creatives, or list_templates.

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 gives concrete routing conditions for the scope parameters (pass advertiserId or creativeId when listing, add the scope to assetId when retrieving) and warns that missing scope yields INVALID_INPUT. However, it offers no guidance on when to choose list_assets over the many other list_* and get_* siblings.

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