Update Asset

update_asset

Idempotent

Renames an asset (and later other metadata). Drive-synced files cannot be renamed here. Related: get_asset, search_assets.

Behavior4/5

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

Annotations already declare the mutation is idempotent and non-destructive, so the safety profile is covered. The description adds genuinely useful behavior beyond that: the drive-sync restriction that blocks renaming in this tool. It stops short of explaining what happens on failure or what the response returns.

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

Conciseness4/5

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

Two short sentences with the action front-loaded and the constraint second; nothing is padded. The trailing 'Related:' list is terse to the point of being cryptic but costs little space.

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

Completeness4/5

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 described, and annotations cover the safety profile. The remaining gap is the forward-looking '(and later other metadata)' phrasing, which leaves an agent unsure whether other fields are currently updatable.

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

Parameters3/5

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

Schema description coverage is 100% and both parameters are documented ('New display name.', 'Asset id.'), so the schema carries the load. The description only implies that 'name' is the renamed field and adds no format, length, or uniqueness semantics beyond the schema.

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

Purpose4/5

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

States a specific verb and resource ('Renames an asset') and disambiguates from siblings by naming get_asset and search_assets as related. The parenthetical '(and later other metadata)' is vague and hints at unbuilt scope, slightly muddying what the tool does today.

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

Usage Guidelines4/5

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

Gives a concrete negative condition: drive-synced files cannot be renamed here. It also points at related tools, though it doesn't say when to reach for get_asset or search_assets versus this one, so the routing is suggestive rather than explicit.

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