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

The description adds valuable behavioral detail beyond the annotations: it discloses downloading, validation, storage upload via Core.UploadFile, Asset creation, and the returned Asset ID. This is more transparent than simply stating 'imports media.' It does not discuss failure behavior or idempotency, but annotations already signal that the operation is not idempotent, softening that 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?

A single, information-dense sentence that front-loads the core purpose and separately lists the side effects and return value. There is no filler or redundant restating of the tool name.

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?

For a tool with one required parameter, high schema coverage, and a clear side-effect chain, the description covers what matters: input type, behavior, destination, and return value. The absence of an output schema is compensated by stating the returned Asset ID. No critical context is missing.

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 100%, so the schema already documents url, filename, and workspace_id adequately. The description adds a small amount of semantic context (e.g., public HTTPS for url and importing into a workspace), but it doesn't significantly go beyond the structured schema information. Baseline 3 is appropriate.

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 names a specific verb ('Imports'), a specific resource (public HTTPS image/video), and the complete pipeline (download, validate, upload, create Asset, return ID). This clearly distinguishes it from asset retrieval or listing tools like invoke_get_asset and invoke_list_workspace_assets.

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?

The description clearly conveys when to use the tool: when a public HTTPS image/video needs to be brought into Socializioz as an Asset. It also adds a meaningful constraint (public HTTPS URL). It does not explicitly name alternatives or exclusion cases, so it falls slightly short of a 5.

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