create_part_property

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It adds one useful constraint (parent must be a Block), but doesn't disclose what happens if the parent isn't a Block, whether the operation is validated, side effects, or the output. For a creation tool with zero annotation coverage, this is a meaningful gap.

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 efficient sentence with no wasted words. The core purpose is front-loaded and the clarifying parenthetical adds value without bloat.

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 values are covered. However, with two parameters at 0% schema coverage, no behavioral guidance, and no usage context, the description is incomplete for an agent deciding how to construct a valid call. More context on parameter semantics is needed.

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 0%, so the schema provides no parameter meaning. The description implies parent_id refers to a Block, which is a partial hint, but neither name nor parent_id is described in the schema or the description. It fails to state what name should contain (e.g., the part name) or the format of parent_id.

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 states a specific verb (Create), a specific resource (PartProperty), and its context ('under a Block'). The parenthetical '(typed composite part)' clarifies what a PartProperty is, helping distinguish it from siblings like create_value_property and create_reference_property. It's clear but doesn't explicitly name the siblings it differs from.

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 is given on when to use this tool versus the many sibling create_* tools (create_value_property, create_reference_property, create_constraint_property, etc.). The agent must infer the distinction from the resource type alone. There's no statement of preconditions or exclusions.

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