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 genuinely new post-condition context beyond the annotations: after removal the artist shows their initial until another image is set, which tells the agent the artist is not left in a broken state.

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 short sentence with the action front-loaded and zero filler. The colon construction reads slightly awkwardly, but no words are wasted.

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 one-parameter destructive tool with full annotation coverage and no output schema, the definition supplies everything essential, including the fallback display behavior. It is only missing a note on whether removal is reversible or requires specific ownership.

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 well-documented required parameter (artist_id, 1-120 chars), so the schema carries parameter meaning. The description adds no extra semantics such as where to obtain the artist id, which matches the baseline 3 for high-coverage schemas.

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?

The description states a specific verb and resource ("Remove the artist's image") and is clearly distinguishable from the sibling set_artist_image. The parenthetical about the initial placeholder is slightly odd syntax but reinforces the outcome rather than obscuring the purpose.

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?

Usage is only implied: the existence of set_artist_image as a sibling makes the add/replace counterpart obvious to an attentive agent, but the description never says when to remove versus replace, nor mentions any prerequisite (e.g., that an image must currently exist).

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