get_manual_compound_entry_file

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is known. The description adds no behavioral detail beyond the basic fetch action, leaving ambiguity about the response format (e.g., whether it returns binary content or a file URL). There is no contradiction with 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 extremely short—a single fragment—which makes it easy to scan. However, it is under-specified and grammatically awkward ('Fetch file of manual compound entry'), so it doesn't earn full marks for structure.

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 two-parameter fetch tool with no output schema, the description is incomplete. It does not explain what the returned file looks like, how to use the two IDs, or when to prefer this over sibling tools like get_manual_entry_file. The openWorldHint and idempotent annotations add some context, but the description itself is minimal.

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?

Both parameters are fully described in the schema (100% coverage), so the description need not add parameter details. It does not add any extra meaning or relationship between manual_entry_id and file_id, but the baseline of 3 is appropriate given complete schema descriptions.

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 the verb 'Fetch' and identifies the resource as 'file of manual compound entry', which is clear at a basic level. However, it does not clarify whether the tool returns file metadata or binary content, and it does not distinguish from sibling tools like get_manual_entry_file or list_manual_compound_entry_files.

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?

No when-to-use or alternative guidance is provided. The description gives no context on when to use this tool versus related file tools such as get_manual_entry_file or download_file.

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