parent_mesh_to_armature

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

With no annotations, the description carries the full burden. It mentions 'automatic weights or other methods' but does not disclose side effects (e.g., adding an armature modifier, creating vertex groups) or what happens to original data. Behavioral impacts are vague.

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 concise with a clear structure: purpose sentence, Args list, Returns line. Every sentence adds value with no redundancy or 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 tool with 3 parameters and no annotations, the description covers basic functionality and parameters. However, it lacks details on prerequisites (e.g., armature must be selected?), error handling, and return value specifics beyond 'Confirmation dict.' Sibling differentiation is absent.

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 input schema has 0% description coverage, but the description documents all three parameters (mesh_name, armature_name, type) with explanations and valid values for type. This adds significant meaning beyond the schema's bare names.

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 purpose: 'Parent a mesh object to an armature with automatic weights or other methods.' It specifies the verb (parent) and resources (mesh to armature), and distinguishes from the more general sibling tool parent_objects by focusing on armature parenting with weight options.

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 implies usage for rigging tasks but does not explicitly state when to use this tool versus alternatives like parent_objects or when not to use it. No context on prerequisites or exclusions is provided.

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