insert_part_from_library

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

With no annotations, the description carries full responsibility for disclosing behavioral traits. It only states that it returns a success/failure message and a screenshot. It does not mention whether it modifies the current document, requires an active document, or has any side effects. This is insufficient for a mutation tool.

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 description is extremely concise and well-structured. It opens with a one-sentence purpose, then uses clear 'Args' and 'Returns' sections. Every sentence serves a purpose, and there is no wasted text.

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?

Given the tool's low complexity (one parameter) and the presence of an output schema, the description is somewhat adequate. However, it lacks usage context and any safety or side-effect information, especially since annotations are absent. For a simple insert operation, it covers the basics but leaves gaps.

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?

The schema description coverage is 0%, so the description must compensate. It provides one line: 'relative_path: The relative path of the part to insert.' This adds basic meaning over the schema's bare title 'Relative Path', but it is still minimal and does not explain the path's base directory or format.

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 clearly states the tool's action with a specific verb ('Insert') and resource ('a part from the parts library addon'). This distinguishes it from siblings like 'get_parts_list' (which lists parts) and 'create_object' (which creates from scratch).

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 alternatives. It does not mention any prerequisites, contexts, or specific scenarios where this tool should be preferred. The sibling list includes related tools like 'instantiate_family' and 'get_parts_list', but the description offers no differentiation.

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