upload_manual_compound_entry_file_file

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

The description adds no behavioral context beyond what the annotations already provide (readOnlyHint: false, destructiveHint: false). It does not mention file replacement behavior, upload constraints, or any side effects, leaving the agent to infer the tool's behavior solely from the name and schema.

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, front-loaded with the action and target. It contains no filler, but it is minimal to the point of being terse, which keeps it from a perfect score.

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 two-parameter upload tool, the description covers the core purpose, but it lacks context about the relationship between manual compound entries and manual entries, file constraints, or how the fileName array should be used. The absence of an output schema reduces the need for return-value documentation, but the missing usage nuances leave gaps.

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 input schema covers 100% of parameters with descriptions for both fileName (array of strings) and manual_entry_id (integer). The tool description adds no additional parameter semantics, so it meets the baseline for high schema coverage without enriching meaning.

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 'Add file to manual compound entry' uses a specific verb (Add) and resource (file) with a clear target (manual compound entry), which is distinct from the sibling 'upload_manual_entry_file_file'. However, it does not explicitly contrast with alternatives, so it misses the top score.

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 guidance is provided on when to use this tool versus alternatives like upload_manual_entry_file_file, nor any prerequisites or conditions. The only implied usage is from the description itself, which is insufficient.

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