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

With no annotations provided, the description carries full burden. It states this is a parenting operation (implies mutation) and mentions different methods, but doesn't disclose permission requirements, whether changes are reversible, potential side effects, or rate limits. For a mutation tool with zero annotation coverage, this leaves significant behavioral gaps.

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 efficiently structured with a clear purpose statement followed by parameter explanations. Every sentence earns its place, though the 'Returns' section could be more informative given no output schema exists.

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 3-parameter mutation tool with no annotations and no output schema, the description does well on parameters but lacks behavioral context. The 'Returns' section is minimal ('Confirmation dict'), leaving the agent uncertain about response format. It's adequate but has clear gaps in behavioral disclosure.

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?

With 0% schema description coverage, the description fully compensates by explaining all 3 parameters: mesh_name ('Name of the mesh object to parent'), armature_name ('Name of the armature object'), and type with its enum values and meanings. This adds crucial semantic meaning beyond the bare 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 clearly states the specific action ('Parent a mesh object to an armature') and distinguishes it from the generic 'parent_objects' sibling tool by specifying the specialized armature parenting with weight methods. It provides verb+resource+method specificity.

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 armature-specific parenting but doesn't explicitly state when to use this vs. the generic 'parent_objects' tool or other alternatives. It mentions 'automatic weights or other methods' which gives some context but lacks explicit comparison or exclusion guidance.

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