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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds only the two-mode behavior (all artifacts vs categorized errors); it says nothing about result volume, pagination, or how large artifact sets are returned.

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?

A single front-loaded sentence with zero filler. It is efficient, though bordering on under-specified for a tool with multiple retrieval modes and several sibling artifact tools.

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 simple read tool with annotations and no output schema, the description is minimally adequate. It does not define what 'categorized errors' contains or how this differs from downloadJobArtifact and getJobArtifactDetail, which is the main open question an agent would have.

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%, and the schema already states that taskId is optional and drives categorized errors. The description restates this rather than adding format, constraints, or interaction details, so the baseline 3 applies.

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?

Clear verb (Retrieve) plus resource (artifacts / categorized errors) scoped to a HyperExecute job or task. However, it does not distinguish itself from close siblings like downloadJobArtifact or getJobArtifactDetail, so an agent cannot tell which artifact-retrieval tool to pick from the description alone.

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?

Usage is only implied: passing taskId selects the 'categorized errors' mode while jobId alone returns all artifacts. There is no explicit when-to-use, no mention of alternatives such as downloadJobArtifact/getJobArtifactDetail, and no note on limits or size of results.

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