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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered elsewhere. The description contributes the useful detail that the read surfaces errors and final output URLs, but says nothing about polling cadence, terminal states, or how long results persist.

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?

One compact, front-loaded sentence with no filler. It is terse to the point of being telegraphic, but nothing in it is wasted.

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?

With no output schema, the description does well to preview the return fields (status, overview URL, errors, output URLs). However, for a status-polling tool the omission of lifecycle semantics and the entirely undocumented group_id leave the definition only minimally complete.

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 0% and the single required parameter group_id is neither typed with meaning nor described anywhere. The description does not explain what a group_id is, where it comes from (presumably create_restyle), or its format, so it fails to compensate for the coverage gap.

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 uses a specific verb ('Check') and names a concrete resource (restyle job group), then lists the fields of interest (status, overview URL, errors, final output URLs). That is enough to separate it from create_restyle and approve_restyle, though it never names a sibling explicitly.

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 statement of when to call this, when not to, or which alternative to prefer. The polling-after-create workflow is only inferable from the phrase 'restyle job group' and the presence of create_restyle/approve_restyle siblings, not stated.

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