Check all image updates

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

The description adds little beyond the annotations. It states the action but does not describe the return format, potential side effects (though annotations indicate none), or whether operation is synchronous or long-running. No output schema further limits transparency.

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 a single sentence without extraneous words. It is appropriately concise for a simple tool, though it could be slightly expanded to cover return behavior without losing conciseness.

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 one-parameter read-only tool, the description is adequate but incomplete. It does not mention what the agent should expect in response (e.g., a list of image updates or a status), which is important for invocation decisions. Annotations help but do not compensate for missing output details.

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 coverage is 100% with a clear description for 'environmentId'. The description adds minimal semantic value by reinforcing that the check occurs 'in an environment', which already matches the schema. No additional formatting, constraints, or examples are provided.

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 (check for updates) and scope (all images in an environment). However, it does not differentiate from similarly named siblings like 'arcane_image_update_check_all', which likely has an identical purpose.

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 (e.g., checking a single image, multiple images by ID, or getting an update summary). The description does not mention any prerequisites, exclusions, or context for selection.

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