background_asset_upload_files_create_instance

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

No annotations are provided, so the description carries the full burden. It reveals only that this is a POST with a JSON:API body, but says nothing about auth scopes, whether the returned upload file must subsequently be used to push bytes, whether the operation is idempotent, or what happens on failure. For a mutation endpoint with zero annotation coverage this is a serious gap.

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

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

The route is stated twice in parentheses, which is pure duplication, and the one substantive instruction (consult the OpenAPI schema) is buried after it. It is short, but the space it occupies is not spent on the agent's actual questions.

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

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

With no annotations, no output schema, and a nested JSON:API request body, the description is the only place behavioural context could live — and it provides none. The pointer to the schema name is marginally useful, but the definition is not sufficient for an agent to invoke this correctly without external API docs.

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

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

Schema description coverage is reported at 100% and there is only one parameter, so the baseline is 3. However, neither the schema nor the description enumerates any real fields of the body — both merely point at 'components.schemas.BackgroundAssetUploadFileCreateRequest', so the description adds no meaning beyond the schema.

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

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

The description is effectively a restatement of the tool name as an HTTP route: 'POST /v1/backgroundAssetUploadFiles'. It never says what a background asset upload file is, why one would create it, or how it relates to background_asset_versions or an actual file upload. An agent cannot distinguish this from siblings like background_asset_versions_create_instance or build_upload_files_create_instance based on the text.

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

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

No when-to-use guidance, no prerequisites, no alternatives. In a sibling set containing dozens of create_instance tools, the description offers nothing that routes the agent to this one over another.

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