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

No annotations are supplied, so the description carries the full behavioral burden, and it does not state whether the removal is reversible (is there an undo?), whether the underlying asset is deleted from the library or merely detached from the screenshot, or what permissions/state ('open editor') are required. Only the implicit mutation is conveyed.

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?

A single front-loaded sentence with no filler or redundancy. It is not padded, though it is arguably too terse given the 0% schema coverage it must compensate for.

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?

With no annotations, no output schema, and no parameter documentation, the description leaves key questions unanswered: side effects on the asset library, undo/redo interaction, and error conditions when the asset or screenshot ID is invalid. For a destructive tool in a 48-sibling surface, this is under-specified.

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% for two required parameters. The phrase 'an image layer from a screenshot' loosely maps assetId to the layer and screenshotId to the screenshot, but no ID format, source, or lookup tool (e.g., get_editor_snapshot/list_library) is mentioned, so the agent cannot reliably populate either field.

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?

Specific verb+resource: 'Remove an image layer from a screenshot in the open editor' tells the agent exactly what is deleted and where it lives. It is reasonably separable from remove_text/remove_div/remove_phone by the 'image layer'/'asset' wording, but it never names a sibling or clarifies how it differs from remove_screenshot or update_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?

No when-to-use guidance, no prerequisites, no alternatives. The agent is not told whether this is the right call versus update_asset (e.g., to hide/replace instead of delete) or which removal tool applies to non-image layers.

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