create_embed_asset

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

Annotations already indicate a non-read-only, non-destructive, open-world operation, so the description adds little behavioral context beyond confirming it creates an embed asset. It does not mention side effects, validation behavior, permissions, or what happens on success. No contradiction with annotations.

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 description is two short, purposeful sentences. The core purpose is front-loaded, and the workspace_id guidance earns its place by addressing a likely lookup need without padding.

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 five parameters and no output schema, the description leaves too much unstated: it never explains how to obtain hub_profile_id, what url should point to, how duration_in_seconds behaves, or what the tool returns. The provided workspace_id hint helps but is not enough for reliable standalone invocation.

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 0%, so the description must compensate, but it only explains workspace_id and how to obtain valid values. hub_profile_id, name, url, and duration_in_seconds receive no semantic explanation beyond their raw schema titles and types.

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 and resource: 'Create an embed asset (external URL embed) in a hub profile.' The parenthetical clarifies exactly what kind of asset this is, and the location scopes it, distinguishing it from related tools like create_media_asset or create_file_asset.

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 'external URL embed' wording implies when this tool is appropriate, and the workspace_id line tells the agent where to get a needed ID. However, it does not explicitly contrast with sibling asset-creation tools or state when to choose one of them instead.

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