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

Annotations already declare destructiveHint=true, readOnlyHint=false, openWorldHint=true, and idempotentHint=false, so the agent knows this mutates state. The description adds the useful detail of what is removed (a flat surrounding page or image box), but says nothing about the effect on the design/session, reversibility, or the warning that supplied patches can overwrite session content (which lives only in the schema).

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 efficient sentence with the effect front-loaded. Minor waste in the phrase 'the existing sticker-cutout operation', which conveys nothing actionable.

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?

This is a destructive mutation with a large nested options object and no output schema. The description does not say what the tool returns, whether the change applies to the live design or only a preview, or how it interacts with the session — all of which an agent needs before invoking a destructive operation.

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 100%, so the baseline is 3. The description's only parameter-adjacent signal is 'selected artwork', hinting at element selection, but it adds no meaning for the many behavioral options (feather, tolerance, paddingPx, colorKeyHex, preserveImageBox, applyToDesign) that an agent must choose correctly.

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 concrete verb and effect: it removes a surrounding flat page or image box from selected artwork, which is more specific than the title alone. It does not, however, differentiate itself from close siblings such as remove_background, extract_artwork, or crop_image, so an agent cannot tell which cutout-style tool to pick without outside knowledge.

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?

'Use the existing sticker-cutout operation' is a restatement rather than guidance; there is no when-to-use condition, no prerequisite (session, selected artwork), and no named alternative among the many sibling image tools. The only implied usage is the phrase 'selected artwork'.

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