Delete a sip user

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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, and the description's single word "Destructive" merely restates that rather than adding context. The endpoint path is mildly useful disclosure, but nothing is said about irreversibility, side effects on dependent objects (short codes, routing targets) or failure behavior when the id is unknown.

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?

Front-loaded verb+resource with the endpoint in parentheses and the risk note last; there is no filler. It is arguably over-terse for a destructive operation, but nothing is wasted.

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 mutation with no output schema, the definition leaves important gaps: what a successful response looks like, what happens to dependent entities, and whether the operation is recoverable. The annotations carry the safety profile, but the description should still warn about consequences of an irreversible delete.

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 100%, so the id and response_format parameters are already documented, including the enum for output format. The description adds no syntax, format or constraint detail beyond the schema, which is the expected baseline here.

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 and resource ("Delete a sip user") and adds the underlying endpoint DELETE /sip_users/{id}, so the agent knows exactly which object is removed and that it targets the sip_users collection rather than generic users. It does not explicitly contrast with sibling placetel_delete_user, but the name and path make the distinction inferable.

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 on when to use this versus alternatives such as placetel_delete_user, or when deletion is inappropriate (e.g., deactivate instead). No prerequisites, no preconditions (does the sip user need to exist, must related short codes be removed first).

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