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

Annotations already declare this as a non-read-only, non-idempotent, non-destructive mutation, but the description adds nothing beyond that — no indication of which fields can change, whether the operation requires specific permissions, or what effect an omitted field has. For a mutation endpoint, the description carries little behavioral weight of its own.

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 short, but the opening sentence is a generic definition of a live asset rather than front-loaded task information. It is not wasteful in length but spends its first half on background that does not help invocation.

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?

An output schema exists so return values need not be explained, but for a mutation tool with three all-optional parameters the description omits what is updatable, the semantics of an empty body, and any behavioral caveats. It is insufficiently complete for correct 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 coverage is only 67% and the description mentions no parameters at all, so it fails to compensate for the gap — notably start_at has an empty schema description. The role of live_asset_id and which fields are optional (all of them) is left entirely to 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 states a clear verb (update) and resource (live streaming asset), and the opening sentence defines what a live asset is. However, it does not distinguish this from sibling tools like update_asset, create_live_asset, or delete_live_asset, and much of the first sentence is definitional rather than task-oriented.

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?

There is no guidance on when to use this tool versus alternatives such as update_asset or live_workspace_update, no prerequisites, and no exclusions. The description merely asserts that updating is allowed without any selecting context.

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