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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool downloads a file but lacks critical details: it doesn't specify the output format (e.g., file content, download link), error conditions (e.g., invalid path), permissions required, or rate limits. This leaves the agent uncertain about the tool's behavior beyond the basic action.

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, efficient sentence that directly states the tool's purpose without unnecessary words. It's front-loaded with the core action ('Download'), making it easy to parse quickly. There's no wasted verbiage or redundant information.

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 lack of annotations and output schema, the description is incomplete for a tool that performs a download operation. It doesn't explain what the tool returns (e.g., file data, download status), error handling, or authentication needs. For a tool with 3 parameters and no structured output information, this leaves significant gaps in understanding how to use it effectively.

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%, with clear descriptions for all three parameters (project_id, tag_name, direct_asset_path). The description adds no additional parameter semantics beyond what the schema provides, such as examples or usage context. Since the schema is comprehensive, the baseline score 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 action ('Download') and the target ('a release asset file by direct asset path'), making the purpose immediately understandable. However, it doesn't differentiate this tool from sibling tools like 'download_attachment' or 'get_file_contents', which might have overlapping functionality for retrieving 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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a release with assets), compare to sibling tools like 'get_release' or 'download_attachment', or specify scenarios where direct asset path is required over other methods.

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