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

With no annotations, the description carries the full behavioral burden. It does disclose that the tool mutates the basket by removing a line and that it returns the updated basket. However, it omits other important behaviors such as idempotency, error handling if the item is not found, permissions, or whether removal is permanent.

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 short sentences with no filler. The core action is front-loaded and the return behavior is stated concisely; 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 two-parameter mutation, the description and schema cover the basics: what to provide, what it does, and what is returned. It is not fully complete because it lacks guidance on when to choose this tool over siblings and does not address failure or edge-case behavior, but the tool is simple enough that this is not a major omission.

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?

Input schema coverage is 100%, so the schema already fully documents both parameters, including their sources (view-basket and create-basket). The description adds no extra parameter semantics beyond restating 'line' and 'basket', so the baseline of 3 is appropriate.

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 names a specific verb ('Remove') and resource ('a line from a basket'), and 'Returns the updated basket' clarifies the operation's output. This makes it easy to distinguish from siblings like add-to-basket, update-basket-item, and view-basket.

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?

No guidance is given about when to use this tool versus alternatives such as update-basket-item or view-basket. There is no mention of when not to use it, prerequisites, or how it fits into the basket workflow beyond the schema parameter notes.

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