fetch_artifact

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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses almost nothing beyond the one-line action. It does not say what 'verified' means, whether an existing file at the destination is overwritten, what permissions are required, or what happens when verification fails.

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?

It is a single, front-loaded sentence with no filler, which is appropriate sizing for a narrow tool. The terseness borders on under-specification, but that is penalized elsewhere rather than here.

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 annotations, no output schema, and three required parameters, the description leaves key gaps: the meaning of 'verified', the relation to siblings like task_artifacts, and any failure or overwrite semantics. An agent can guess the happy path but cannot call this confidently in edge cases.

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 reported at 100%, so the structured schema already documents the parameters and the baseline of 3 applies. The description adds only the loose notion that the fetched artifact lands on the coordinator host, which partially maps to 'destination' but adds no syntax or format detail.

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 states a specific verb (fetch), resource (one verified artifact) and destination (the coordinator host), so the action is unambiguous. It does not, however, distinguish itself from related siblings such as task_artifacts or stage_bundle, which an agent must infer from names 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?

There is no when-to-use guidance, no prerequisites, and no named alternative for retrieving artifacts (e.g. task_artifacts for listing). The word 'verified' hints at a gating condition but the description never explains it or says when this tool should be preferred.

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