get-file-by-id

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

No annotations are provided, so the description must disclose behavioral traits. It only states that it finds a file by ID, implying a read operation but not disclosing any details such as response format, error behavior, or how the 'includes' parameter affects results. This is minimal behavioral disclosure, so score 2.

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 front-loaded sentence with no unnecessary words. It efficiently states the core purpose, though it may be too brief for other dimensions. For conciseness and structure, it earns 5.

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?

The tool description is extremely minimal. It lacks context about the optional 'includes' parameter, return behavior, or when to choose this over the sibling get-files or other file tools. Given the simplicity of the schema and lack of annotations/output schema, the description is not adequately complete for an agent to fully understand usage, so score 2.

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 covers the only parameter with a description ('includes parameter'), providing 100% coverage. Since the description adds no parameter semantics beyond the schema, a baseline of 3 is appropriate.

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 clearly states the tool's function with a specific verb ('Find') and resource ('file') identified by ID. This inherently distinguishes it from sibling tools like add-file, update-file-by-id, and delete-file-by-id, though it doesn't explicitly name alternatives. The purpose is unambiguous but lacks explicit sibling differentiation, so 4.

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 description provides no guidance on when to use this tool versus alternatives. It does not mention that get-files lists files without an ID, or that this tool requires a known ID. There is no when-to-use or when-not-to-use context, so score 2.

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