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

The description contradicts the annotations: it claims 'retries are safe' and that an already-deleted item counts as success, which implies idempotent behavior, while idempotentHint is false. This is a clear contradiction. The description does add transparency about permanence, but the contradiction is a severe issue.

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?

Two sentences with no filler. The core action is front-loaded, followed by a required prerequisite and critical warnings (permanence, retry safety). Every sentence earns its place.

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 simple 2-parameter delete with no output schema, the description covers the essentials: how to find the ID, the permanence, and retry behavior. It doesn't discuss errors or side effects, but given the simplicity and annotations, it's largely complete. The idempotency contradiction is noted but doesn't directly detract from this dimension.

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 both parameters already described in the schema. The description reiterates 'from item-list' but adds no new meaning beyond that, so it's at the baseline 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 clearly states the verb ('Remove') and resource ('item from actor's inventory') with a permanent consequence, distinguishing it from update/create tools and other delete tools. It is specific and unambiguous.

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?

Provides explicit sequencing ('Use item-list FIRST to find itemId') and retry guidance ('retries are safe'). It doesn't explicitly state when not to use, but the purpose is clear enough that alternatives aren't needed; the guidance is actionable and context-rich.

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