rename_element

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'rename' with no mention of side effects (e.g., impact on references, reversibility, permissions, name uniqueness). A mutation tool with zero annotation coverage should provide more context.

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 short sentence, so it is front-loaded and waste-free, but it is too terse to be useful. While concise, it sacrifices necessary context, making it inadequate for the tool's complexity.

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 tool is a mutation with no annotations and no behavioral detail. It lacks information about return values, error conditions, or interactions with other model elements. Given the presence of a output schema (not shown), the description should at least hint at what the tool returns. This is incomplete for an agent to call correctly.

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 coverage is 0%, and the description adds no explanation of 'element_id' or 'new_name' beyond their titles. It does not clarify what an element ID is, what formats are acceptable, or whether the new name has constraints (e.g., uniqueness, allowed characters). The description fails to compensate for the schema's lack of detail.

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 specific verb ('rename') and a resource ('SysML v1 element'), clearly distinguishing it from creation/deletion/movement tools. However, it does not mention any scoping (e.g., which element types) or differentiate from the many set_* tools that also modify elements, so it's not perfect.

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 guidance on when to use this tool versus alternatives. It does not mention any prerequisites, constraints, or contexts where renaming is appropriate or forbidden. The agent must infer usage solely from the verb, which is inadequate.

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