get-trace-attachment

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

No annotations are provided, and the description does not disclose behavioral traits beyond the basic action. There is no mention of idempotency, error handling (e.g., what happens if attachment not found), permissions, or whether content is returned as binary or URL. For a read operation, more context about the response would be valuable.

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 sentence of 10 words that efficiently states the purpose. It front-loads the key information (action and resource) and avoids any unnecessary wording.

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 output schema, the description should ideally indicate what is returned (e.g., file content, metadata). It does not. Additionally, no information about error conditions or edge cases is provided. For a simple get operation, this is minimally acceptable but incomplete.

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 100% (both parameters have descriptions in the schema). The description adds the version requirement but does not provide additional meaning for the parameters beyond what the schema already offers. Baseline 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 verb 'Get', the resource 'attachment on a trace', and the identifier method 'by ID'. It also includes a version note (MLflow 3.9+), which is helpful context. This distinguishes it from sibling tools like 'list-trace-attachments' that list attachments.

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 implies usage requires trace and attachment IDs but does not explicitly state when to use this tool versus alternatives like 'list-trace-attachments'. It lacks guidance on prerequisites or situations where other tools are preferable.

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