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

Annotations declare a non-read-only, non-idempotent write operation, and the description's 'update' is at least directionally consistent with that. However, it discloses nothing beyond the annotation payload: no permission requirements, no note on which fields are mutable vs immutable, no mention of whether updating a live asset interrupts an active stream. For a live-media mutation, that is a meaningful 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 first sentence is a domain glossary entry ('A live asset refers to media content/video that is live-streamed through Gumlet') that consumes half the text without describing this tool's action. The second sentence is the only purpose-bearing claim, and it contradicts 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?

An output schema exists, so return values need not be explained, but the description still fails the core burden: an agent cannot determine whether this creates a copy or updates an asset, what triggers success, or what prerequisites exist for a live-stream mutation with zero required parameters.

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 67%, with start_at carrying an empty schema description and live_asset_id only a terse one. The description adds zero parameter meaning and never clarifies how title, start_at, and live_asset_id relate to the stated 'update' operation, nor why all three are optional for a supposedly mutating call.

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 tool is named create_live_asset_copy (implying creation of a copy) but the description states it 'allows users to update a live streaming asset.' This verb mismatch leaves an agent unable to tell what the tool actually does, and it does not differentiate from the many siblings such as create_live_asset, update_asset, or delete_live_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?

There is no when-to-use, when-not-to-use, or alternative routing whatsoever. With siblings like create_live_asset, complete_live_stream, start_live, and filter_live_assets all operating in the same live-asset domain, the absence of any disambiguation makes the tool effectively unselectable.

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