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

No annotations are provided, so the description carries the full burden. It implies a destructive mutation but says nothing about reversibility (siblings include undo/redo), permission requirements, failure modes for a bad divId/screenshotId, or side effects on other layers. This is a significant gap for a delete operation.

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, which is good structure. However, for a destructive two-parameter tool with zero structured documentation, the extreme brevity shades into under-specification rather than pure conciseness.

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, 0% parameter coverage, and a large sibling set, the definition leaves essential questions unanswered: what happens to the removed layer, whether the action is undoable, and what the call returns. Adequate for identifying the tool, insufficient for calling it confidently.

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%, so the description must compensate and largely does not. 'a box layer' and 'a screenshot' loosely correspond to divId and screenshotId, but no ID format, source, or constraint is given for either required parameter.

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?

States a specific verb+resource ('Remove a box layer') and scopes it to a screenshot in the open editor. This distinguishes it adequately from remove_asset, remove_text, remove_screenshot and remove_phone, though the 'box layer' wording only implicitly maps to the 'div' in the tool name.

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?

Gives no when-to-use guidance, no prerequisites (e.g., editor must be open, screenshot must exist), and never names an alternative such as update_div for modifying rather than deleting a layer. The phrase 'in the open editor' is the only contextual anchor.

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