parent_to_armature

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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It states the operation is to bind meshes, implying mutation, but does not disclose side effects like vertex group creation, weight assignment, or the need for existing armature bones. The method enumeration adds some detail but fails to warn about irreversible changes or dependencies.

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, using a single sentence and a list. It is front-loaded with the primary purpose. However, it could be better structured by separating the method details into a dedicated section, but overall it is efficient and has no wasted words.

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 mutation tool with no annotations and no output schema, the description is incomplete. It does not mention prerequisites (e.g., selection requirements), return values, or potential side effects. The agent is left without critical information needed to safely invoke the tool.

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 description coverage is 0%, so the description must compensate. It does explain the 'method' parameter with its possible values (AUTOMATIC, ENVELOPE, EMPTY_GROUPS, DEFORM), which adds meaningful context. However, 'objects' and 'armature' are only implicitly defined by the main sentence; there is no explicit clarification of expected types or format, so it only partially compensates for the schema gap.

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 action (bind mesh to armature) with a specific verb and resource. It distinguishes the tool as a skinning operation, though it does not explicitly contrast it with sibling tools like set_parent, so it is clear but not perfectly differentiated.

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, such as set_parent or other rigging tools. There are no conditions, prerequisites, or exclusions mentioned, leaving the agent to infer usage.

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