ensure_active_update_set

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

The description discloses the key behavioral trait: automatic creation if no active update set exists. This adds value beyond annotations (idempotentHint, destructiveHint) by explaining the conditional creation. The '[Scripting]' tag also hints at an intended execution 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 extremely concise: a single sentence covering the core functionality plus a brief context tag. Every word is meaningful, and the structure is front-loaded with the most important information.

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 simplicity of the tool and the existence of comprehensive annotations, the description is minimally adequate. However, it lacks any mention of the return value or how the tool's outcome is communicated, which would improve completeness for an agent relying solely on descriptions.

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 parameter 'default_name' is already well-documented in the schema. The tool description does not add any additional parameter information, justifying a baseline score of 3.

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's action: 'Ensure an Active Update Set exists; create one automatically if none is in progress.' It uses a specific verb ('Ensure...exists') and resource ('Active Update Set'), and distinguishes it from siblings like 'create_update_set' and 'get_current_update_set' by combining both find and create behaviors.

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?

The description provides no explicit guidance on when to use this tool versus alternatives. It does not mention when to prefer this over 'get_current_update_set' or 'create_update_set', nor does it exclude any scenarios. The usage context is implied but not clarified.

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