flix_get_transfer_status

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits, but it only says 'Get' with no mention of side effects, safety, return format, or potential errors. The tool's behavior is essentially opaque.

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 a single, concise sentence with no unnecessary words. It is efficiently front-loaded and does not waste characters, earning high marks for conciseness.

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?

Given the simplicity of one parameter and no output schema, the description is minimal but lacks essential context such as what statuses are possible, how to interpret results, and whether any prerequisites exist. A more complete description would mention typical usage or expected output.

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 fully documents the single parameter 'transferId' with description 'Transfer ID to check', so schema coverage is 100%. The tool description adds no extra meaning beyond the schema, and the baseline of 3 is appropriate since the schema handles parameter semantics.

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 'Get file transfer status' clearly states the action (get) and resource (file transfer status), making the tool's purpose evident. It is distinct from sibling transfer tools like cancel/pause/resume which focus on control actions, though it does not elaborate on what 'status' entails.

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 guidance on when to use this tool versus alternatives, such as after starting a transfer or in conjunction with send/receive operations. No prerequisites or context for use are implied, leaving the agent without directional cues.

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