v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavior. It only restates the creation action and gives an analogy, but does not explain effects on the model, required model state, potential failures, or what happens when validation fails.
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 short and free of redundancy, which aids readability. However, it is under-specified for a constraint-creation tool; the single sentence does not provide enough operational context, so conciseness comes at the cost of completeness.
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 complexity, the lack of annotations, and 0% schema description coverage, the description is incomplete. It does not explain prerequisites, how host_region and embedded_region relate, validation behavior, or when this constraint type is appropriate, leaving an agent to guess at correct invocation.
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. The example 'reinforcement in concrete' subtly clarifies that embedded_region is the inserted object and host_region is the surrounding material, but timeout and model_name receive no explanation, and this minimal hint is insufficient to fully document the parameters.
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 a specific action and resource: 'Create an embedded region constraint' and gives a concrete example ('reinforcement in concrete'). It is not a tautology and is distinguishable from sibling constraint-creation tools through the unique resource type, though it does not explicitly contrast with any sibling.
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 usage guidance is provided. The description does not state when to choose this tool over other constraint creators such as create_tie, create_coupling_constraint, or create_mpc_constraint, nor does it mention any prerequisites like needing the host and embedded regions to already exist.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
