+]v0.3.1Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare destructiveHint=true, and the description adds a genuinely useful trait not in the annotations: the deletion is wrapped in an undo step, so it is reversible. It stops short of describing side effects such as what happens to children/tags of a deleted object or to materials still assigned to objects.
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 front-loaded sentence with the verb first and zero filler. Nothing can be trimmed without losing the undo-step fact.
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 one-parameter destructive tool with no output schema, the description covers the core action and reversibility, which is close to sufficient. It omits what the call returns on success and any failure behavior for unresolvable handles or cascade effects on related entities.
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% and the handle union is fully described in the schema, so the baseline is 3. 'The resolved entity' adds a small hint that the handle must come from a resolution step rather than being hand-constructed, but no format or example detail is added beyond the schema.
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+resource ('Delete the resolved entity'), which is unambiguous and clearly distinct from siblings like create_entity, move_entity, and clone_entity. It does not, however, explicitly name any sibling or scope limit (e.g., single entity only, not a batch operation like `batch`).
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 named alternative. The parenthetical about the undo step hints that the operation is reversible via the `undo` sibling, but the agent must infer that itself; nothing tells it when to prefer this over reset_scene or batch deletion.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
