Delete User Profile

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

No annotations are supplied, so the description carries the full behavioral burden. It usefully discloses that deletion is 'complete' and spans both virtual and persistent storage, which is real added context. But it omits critical traits for a destructive operation: whether deletion is permanent or recoverable, what happens if the profile does not exist, and whether related data is cascaded.

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?

The core two sentences are front-loaded and clear, but the trailing bulleted list adds bulk without information: 'Cleaning up old profiles' and 'Removing profiles no longer needed' are effectively the same case. The definition could be half as long with no loss.

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?

An output schema exists, so return-value explanation is rightly omitted. Still, for an unannotated destructive tool with a nested input object, the definition should address irreversibility, no-op/not-found behavior, and whether the deletion can be undone—none of which appear.

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% with a single well-described profile_id, so the schema already does the work. The description adds no format, sourcing, or validation meaning beyond 'the profile to delete,' which is the expected baseline of 3 when the schema is fully documented.

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 opens with a specific verb+resource ('Delete a user profile') and clarifies scope by saying it searches both virtual and persistent storage. Siblings like create_user_profile, get_user_profile, and list_user_profiles are distinguishable by name, though the description never explicitly contrasts itself with them.

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 'Use this tool when' list gives usage contexts, which is better than nothing. However, the four bullets are largely restatements of each other (cleaning up, removing no-longer-needed profiles), and there is no guidance on when NOT to use it, no prerequisites, and no mention of alternatives.

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