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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds real behavioral context the annotations lack: newest-first sorting, hidden cleared artifacts, and the exact fields 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 tightly packed sentence front-loads the resource, ordering, and filtering before the fields. The trailing endpoint-twin reference is useful for mapping but slightly redundant.

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 compensates by enumerating returned fields, and it covers ordering and filtering. Pagination or result-size limits for a list endpoint are not addressed, which is the only notable gap for a simple one-parameter read.

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 the single request_id documented as 'the project (request) id'. The description's 'a project's ARTIFACT folder' adds no information beyond that schema text, 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?

States a specific verb and resource ('List a project's ARTIFACT folder'), plus ordering and returned fields. The plural/singular contrast with get_artifact and post_artifact is unmistakable without opening any schema.

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?

Ordering ('newest first') and the exclusion of cleared artifacts imply how the tool behaves when used, but there is no explicit when-to-use-this-vs-get_artifact guidance or stated prerequisites beyond the request id.

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