smokeball_get_file_download_url

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the routing-authority constraint and the notable detail that `effect` must be "read" and Spring verifies it, which is useful behavioral context. The approval_ref note mentioning "resuming a write" is slightly incongruous in a read-only tool, but it does not formally contradict the annotations.

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 efficiently structured: an identity line, a one-sentence routing constraint, then a clean Args block with each parameter on its own line. There is minimal waste; the only redundancy is the first line duplicating the tool name.

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?

An output schema exists, so return values are handled, and the description covers routing plus all parameter names. The significant gap is the absent semantics of the `arguments` payload, which is the actual instruction for obtaining a download URL — the single most important knowledge an agent needs. The confusing "resuming a write" phrasing for approval_ref also adds noise without clarifying when that field matters.

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 0%, so the description carries the full burden and does enumerate all 7 parameters with one-line definitions, which is credit-worthy. However, the crucial `arguments` parameter is described circularly as "JSON string of arguments for the connector operation" — it does not say what content the operation expects (e.g., which file identifier is needed), leaving the agent unable to construct the actual payload.

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 opens with "Smokeball connector operation `get_file_download_url`" which merely restates the tool's name without defining what it accomplishes. It never explicitly says the tool retrieves a download URL for a Smokeball file, and the only additional clause about routing authority doesn't clarify the verb+resource relationship. The purpose is only inferable from the name itself.

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 only usage signal is "Routes only through the exact project/account governed connector authority," which constrains how invocation happens but not when to choose this tool versus siblings. There is no mention of alternatives like smokeball_get_file, smokeball_list_files, or smokeball_api_request, and no when-not-to-use conditions.

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