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 structurally. The description adds genuinely new behavioral context: the action cannot be undone and the caller should confirm first, which is a workflow requirement not encoded in the annotations.

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 front-loaded sentence carrying purpose, parameter provenance, irreversibility, and a confirmation cue. No filler and nothing redundant.

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 annotations covering safety and an output schema covering returns, the description supplies the missing prerequisites and reversibility warning. Only the absence of alternative-tool routing keeps it from being fully complete.

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% and the single parameter's description already states it comes from list_bucket_lists, so the description largely repeats the schema. It adds no format, type, or validation detail beyond provenance. Baseline 3 is appropriate when the schema does the heavy lifting.

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 action on a specific resource (stop a bucket list) and its title matches 'Remove a bucket list'. The verb 'stop' is slightly softer than the actual destructive removal, but the reference to bucket_id from list_bucket_lists anchors it clearly against siblings like add_flight_bucket_list and update_bucket_list.

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 gives a clear precondition (obtain bucket_id from list_bucket_lists) and an operational instruction ('confirm first'), which is more than most definitions offer. It does not explicitly contrast itself with update_bucket_list or the add_* siblings, so it stops short of full when/when-not guidance.

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