test_download_clients

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

With no annotations, the description carries the full behavioral burden. It discloses that omitting id tests every client, which is useful, but it does not mention potential side effects, required permissions, or what the test result looks like. Still, the operation is a connectivity test, so its non-destructive nature is reasonably implied.

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?

Two sentence, front-loaded with the action, then the key behavior, then the use case. Every word earns its place; no 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?

For a simple single-optional-parameter test tool, the description gives the purpose, the behavior when id is omitted, and the symptom it addresses. The only missing piece is explicit output/result semantics, but the simplicity of the tool makes this a minor 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?

Schema coverage is 100% and the id parameter is already well-described in the schema. The description reinforces the optionality and the 'test all' behavior, but adds no new parameter-level syntax or format details beyond the schema.

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 uses a specific verb ('Test') and resource ('download client connectivity'), clearly distinguishing this from list_download_clients and other test tools like test_indexers. The diagnostic purpose is immediately understandable.

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?

It gives a clear, concrete trigger: 'Run this when grabs never reach the queue.' It does not explicitly name alternative tools or when not to use it, but the diagnostic context is strong enough for an agent to route correctly.

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