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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety bar is partly met; the description adds genuinely new behavior: an explicit user-approval gate with confirmed=true, the credit-use tie-in, and the fact that writes are never auto-retried. It stops short of describing partial-failure or batch semantics for up to 10,000 IDs.

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?

Four short sentences, front-loaded with the action and then the constraints. No filler, though the redundant first two sentences restate the same removal action rather than adding information.

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 nested-body mutation with no output schema and low parameter coverage, the description covers approval and retry behavior but omits what a caller should expect on partial failures, whether removal is reversible, or how list_id relates to the returned state.

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 only 33%, and the two body fields carry no inline descriptions beyond the enum values. The description partially compensates by naming both ID kinds (property/person) and the confirmed flag, but it leaves the default id_type of internal_property_id and the 10,000-item cap unaddressed.

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 ('Remove items from list'), then narrows it to 'specific property or person IDs'. This cleanly separates it from dealmachine_delete_lists_list_id (which removes the list itself) and dealmachine_list_add_items.

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 description gives a precondition ('Requires user approval and confirmed=true') but never says when to choose this over list_add_items or the list-level delete, nor what conditions make removal appropriate. Usage context is implied rather than directed.

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