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

Annotations already declare destructiveHint=true, so the safety profile is partly covered. The description adds genuinely useful context by stating the deletion is permanent and limited to addresses owned by the connected account, but it says nothing about reversibility guarantees, confirmations, or failure modes.

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?

One sentence, front-loaded with the destructive verb, zero filler. Nothing could be trimmed without losing meaning.

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 single-parameter mutation with no output schema, the description covers irreversibility and ownership scope but leaves the parameter unexplained. Adequate but with a clear gap on how to supply 'code'.

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% and the single parameter 'code' is never mentioned in the description. An agent gets only the name and the regex pattern from the schema, so the description does not compensate for the missing semantic explanation of what 'code' identifies.

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 gives a specific verb ('Permanently delete') and resource ('an address'), plus a scope qualifier ('owned by the connected account'). It is unambiguously distinct from siblings like patch_address or list_addresses, though it never names an alternative explicitly.

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?

There is no when-to-use guidance and no mention of alternatives such as patch_address for modification or share_address for delegation. The only implied condition is ownership by the connected account, which is a constraint, not usage guidance.

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