download_artifact

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

Despite having no annotations, the description discloses key behaviors: it checks artifact status before downloading, only includes 'path' on success, and defaults to the latest artifact. It could detail what happens when the artifact is incomplete, but the output shape and conditional presence of path cover the main concerns.

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 compact and well-structured, with a clear purpose-first opening and concise follow-up sentences about default behavior and return format. No filler or redundancy.

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?

The tool is simple, and the description covers the primary workflow and return shape. Minor gaps like incomplete status handling and dest_dir specifics remain, but the output schema and brevity reduce the overall completeness gap.

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?

The schema has 0% description coverage, so the description must compensate. It adds important semantics for artifact_id (None means latest) and implies dest_dir's role via 'download to disk'. However, dest_dir itself is not explicitly explained, and notebook_id is left to the reader.

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 identifies the tool's action: check status and download an artifact to disk. It also specifies the default behavior when artifact_id is None, making the tool's scope unambiguous and distinct from siblings.

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 provides clear context for when to use the tool, including the option to omit artifact_id to fetch the most recent artifact. It doesn't mention alternatives or exclusions, but the use case is well implied.

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