Update autoscaling config

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

Annotations already indicate readOnlyHint=false, destructiveHint=false, and idempotentHint=true, which the description aligns with via 'Update'. The description adds the API call details but does not elaborate on side effects or behavior beyond what annotations provide. No contradiction.

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?

Two concise sentences, front-loaded with the purpose and then a link to documentation. No fluff, but could be slightly more specific about what the update entails (e.g., enabling autoscaling).

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 an update tool with nested objects, the description is minimal but references the API endpoint. It lacks details on return values, error states, or preconditions. Schema covers parameter details, but the description could be more complete given the tool's complexity.

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 covers 60% of parameters with descriptions (max, min, cpu, memory), but the description itself adds no parameter information. The nested `criteria` object lacks a top-level description, and the description does not compensate for this gap. Adequate but no added value.

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 'Update autoscaling config' and specifies the API endpoint (PUT /services/{serviceId}/autoscaling). It distinguishes from siblings like render_scale_service (manual scaling) and render_delete_autoscaling_config (deletion), making the tool's purpose 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?

The description does not explicitly state when to use this tool versus alternatives, nor does it mention prerequisites or conditions (e.g., service must exist). However, the context of updating autoscaling is implied, and the sibling list provides some implicit differentiation.

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