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

Beyond the destructiveHint/readOnlyHint annotations, the description discloses concrete side effects: verification of constraints and X positions, assembly regeneration and save, and recycling of older versions of the assembly family. It does not fully define what 'recycles' entails or failure behavior, but the core destructive behavior is clearly exposed.

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?

Three dense sentences with no filler; each clause contributes operational detail. The first word 'Read' slightly undersells the destructive write nature of the tool, but overall the structure is efficient and front-loaded for a complex six-parameter operation.

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?

The description covers the main workflow but omits return-value behavior, failure conditions, and exact prerequisites for what constitutes the 'current expected assembly'. With no output schema and a destructive mutation, an agent would still have meaningful uncertainty about how to invoke it correctly in edge cases.

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 only 17%, so the description must compensate. It adds meaning by identifying target_insert_surface_ids as the two cylindrical assembly surfaces and target_x_positions as X positions, and by referring to expected_assembly and component references. However, expected_component and source_component_feature_id are not clearly distinguished, so the parameter mapping remains incomplete.

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 precise operation: read one existing ALIGN+INSERT-constrained component instance and add two more while changing only specified cylindrical surfaces and X positions. This clearly distinguishes it from generic component-add siblings like creo_add_project_component_align_insert_three.

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 when to use it—when repeating an existing component instance in an expected assembly with a specific constraint method—but does not explicitly name alternatives or state when not to use it. The trigger context is present but differentiation is left to inference.

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