SetGDLParametersOfElements

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered structurally. The description adds nothing beyond that: it does not say whether existing parameter values are overwritten, whether array resizing is destructive, or what happens on partial failure, despite setting GDL values being an overwrite 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?

It is a single front-loaded sentence with no padding, which is good. It is arguably too terse for a destructive nested-schema tool, but there is no filler or redundancy.

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 destructive, nested-schema mutation tool with no output schema, the description is inadequate: it omits any behavioral context about overwriting, resizing, or failure modes. The annotations carry the safety signal but the description fails to add the context an agent needs to call this confidently.

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 100%, so the nested parameter details (name/index/value/index1/index2) are fully documented in the schema itself. The description adds no parameter-level meaning on top of that, which is the expected baseline when the schema does the heavy lifting.

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 concrete verb and resource ('Sets the given GDL parameters of the given elements'), so an agent knows it mutates parameter values. However, it does not differentiate itself from the obvious sibling GetGDLParametersOfElements, which would help confirm this is the write counterpart.

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 the read-only GetGDLParametersOfElements or other setter tools, and no prerequisites or conditions are mentioned. The only extra text, '(Tapir, Element Commands)', is a provenance tag, not usage guidance.

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