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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds real value beyond them: the Look must belong to the workspace, and a public Look's reward is returned as a side effect. It still doesn't say whether deletion is permanent or how failures are surfaced.

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?

One compact sentence, front-loaded with the action and resource. The parenthetical consequence is efficiently attached rather than buried in a second paragraph.

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 destructive, single-parameter tool with no output schema, the definition covers ownership scope and the reward side effect, which is a reasonable minimum. It remains silent on irreversibility and post-deletion behavior, which an agent invoking a destructive call would want to know.

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 100% with a single documented look_id and an explicit id pattern, so the schema carries the parameter semantics. "The workspace's own Look" implies the id must resolve to owned content, a mild addition beyond the schema, but no format or error semantics are added.

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?

"Removes the workspace's own Look" gives a specific verb plus resource and adds an ownership qualifier, so the agent knows this deletes a Look rather than a Lookbook or plan. It does not explicitly say "music video Look" or distinguish itself from the sibling delete_look, so differentiation rests partly on the name and title.

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 never states when to call this versus delete_look, delete_music_video_lookbook, or delete_music_video_plan, nor does it mention prerequisites before deletion. The "workspace's own" phrasing hints at a restriction but gives no actionable when-to-use guidance.

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