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

Annotations already flag destructiveHint=true and readOnlyHint=false, and the description adds real value on top: confirm is mandatory, the default is single-copy removal, there is no delete_all, and quantity:0 is an invalid pattern. It still omits what happens to the removed copy (irreversible? returned in the response?), so the destructive consequence is asserted but not described.

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?

Four short sentences, front-loaded with the action and then the guardrails; nothing is padded. The telegraphic fragments ('There is no delete_all') read as preemptive error prevention rather than filler, though the quantity:0 remark is cryptic without context.

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, 3-parameter tool with no output schema, the safety guardrails are decent but the definition leaves gaps: copyId is undefined, and the return behavior after a successful removal is unstated. An agent could call it correctly but would not fully understand what it is destroying.

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?

With schema coverage at 33%, only removeOne is documented in the schema, and the description usefully repeats its true/false semantics and default while stressing that confirm must be true. copyId, the most important identifier, is never explained — no hint whether it is a card, printing, or stack identifier — and the quantity:0 warning references a parameter that does not exist in the schema.

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 opens with a specific verb and resource ('Remove copies'), and the parenthetical '(one copy from the stack)' clarifies the unit of removal, implicitly distinguishing it from bulk or sealed-item removal siblings like remove_sealed. It stops short of naming a sibling explicitly, so an agent must infer the boundary itself.

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?

It does give operative conditions: default removeOne=true removes a single copy, removeOne=false targets the whole stack, and confirm=true is always required. However it never states when to prefer this over update_copy or how it relates to collection listings, so guidance is implied rather than explicit.

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