Create Update Set

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

Annotations already indicate this is not read-only (readOnlyHint=false) and has open world side effects (openWorldHint=true). The description adds only 'This creates a new update set on the instance,' which is redundant with the tool's name. It does not disclose potential side effects, permissions required, or implications of creation.

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 very short, but the 'IMPORTANT' sentence is somewhat redundant with the title and adds little value. It is not wasteful, but it could be more informative with the space used.

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 create operation with no output schema and minimal annotations, the description should explain prerequisites, potential side effects, or what happens on success. It lacks any contextual information beyond the action itself, making it incomplete for an agent to understand the full impact.

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?

The input schema covers 100% of parameters with detailed descriptions (name, instance, application, description). The tool description adds no additional parameter semantics beyond what the schema already provides, so baseline score of 3 is appropriate.

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 action: 'Create a new update set.' This is a specific verb+resource pair that distinguishes it from sibling tools like clone_update_set, list_update_sets, or set_current_update_set. The added 'IMPORTANT' clause reinforces that it operates on the instance.

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. It does not mention scenarios where creating an update set is appropriate or when to prefer clone_update_set or set_current_update_set. The description provides no context for selection.

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