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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description's 'explicit confirmation' largely restates the schema's confirmed const:true constraint and adds no further behavioral detail such as permanence of deletion or effect on defaults.

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 tight sentence with the destructive action front-loaded and no filler. Nothing is wasted, though its brevity leaves gaps it could have filled given the low schema coverage.

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, non-read-only mutation with no output schema, the entry covers the confirmation requirement but omits consequences: whether deletion is permanent, what happens to a default address, or what the response indicates. Annotations cover the safety hints, so this is minimally 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 description coverage is 0% for two parameters, so the description must carry meaning. It maps implicitly onto both: 'one saved delivery address' corresponds to addressId and 'explicit confirmation' to confirmed. This is adequate but adds no format, identity, or semantics beyond what the schema's uuid pattern and const already convey.

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?

States a specific verb (delete) and a precisely scoped resource (one saved delivery address), which distinguishes it from the sibling customer_address_update/list/create tools. It is clear and direct, though it does not explicitly name an alternative tool.

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?

The phrase 'after explicit confirmation' implies a precondition for use, matching the required confirmed=true parameter, but there is no guidance on when to delete versus update, or what to do when an address is the default. Usage context is implied rather than stated.

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