create_allocation

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states that it creates a relationship, but does not mention side effects, validation, return behavior, or whether it modifies the model permanently. The agent gets no insight into potential failure modes or constraints beyond the basic operation.

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 a single, efficient sentence with no redundancy. It front-loads the core purpose. However, it is almost too sparse, leaving out useful context, but for a simple tool this brevity is acceptable.

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 moderate complexity (3 parameters, no enums, output schema present), the description is insufficient. It does not explain which source and target elements are valid, whether the relationship has constraints, or how it integrates with the broader SysML modeling workflow. The description leaves too much to inference for an agent to use it reliably.

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 mentions 'from source to target' which loosely maps to source_id and target_id, but it does not explain the name parameter or clarify the expected types or formats of the IDs. The description adds minimal value over the schema titles.

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 creates a SysML Allocation relationship from source to target, which is specific and distinguishes it from other create_* tools by naming the relationship type. It does not explicitly contrast with siblings like add_dependency or create_generalization, but the purpose is unambiguous.

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?

There is no guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. It simply states what it does without context about which elements can be allocated or when an allocation is appropriate, leaving the agent to infer usage from the name and schema.

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