Get image update summary

arcane_image_get_update_summary
Read-onlyIdempotent

Retrieve a summary of available image updates across all containers in an environment. Quickly identify which containers have pending updates.

Instructions

Get a summary of available image updates across all containers

Input Schema

NameRequiredDescriptionDefault
environmentIdYesEnvironment ID
Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, covering key behavioral traits. The description adds minimal context ('across all containers') but does not detail response format, pagination, or other behaviors beyond the annotation-provided safety profile.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no wasted words. It efficiently conveys the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool lacks an output schema and the description does not elaborate on what the summary contains (e.g., list of images, update counts, etc.). An agent would have incomplete information to fully predict the tool's output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with a single parameter 'environmentId' described as 'Environment ID'. The description adds no additional meaning or constraints beyond what the schema provides, meeting the baseline but not exceeding it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool gets a summary of available image updates across all containers. It uses a specific verb ('Get') and resource ('summary of available image updates'), but does not differentiate from similar sibling tools like arcane_image_check_updates_all, which likely also deals with image updates.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, use cases, or scenarios where this tool is preferred over other image update tools.

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