Behavior2/5

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

With no annotations, the description carries full transparency responsibility. It states the tool downloads and returns data, but does not disclose whether the operation is destructive, requires specific permissions, or has rate limits. The read-only nature is implied but not explicit.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, focused sentence that concisely states the action and return value. It is front-loaded and avoids unnecessary words. However, it could be expanded slightly to include usage context without becoming verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given a single required parameter and no output schema, the description is insufficiently complete. It does not explain the return structure (what 'metadata' means), error conditions, or how to obtain the documentId. The tool is simple, but the description leaves important gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 0% description coverage, and the description does not explain the 'documentId' parameter beyond its name. No guidance is given on its format, origin, or acceptable values (e.g., ID from 'kairo_list_documents'). The description adds no semantic value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool downloads the original PDF and returns metadata plus base64 bytes. However, it does not differentiate from the sibling tool 'kairo_download_signed_pdf', which likely downloads a signed version. The verb and resource are specific, but the lack of distinction slightly reduces clarity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 over alternatives like 'kairo_download_signed_pdf' or 'kairo_get_document'. The description does not mention prerequisites, such as needing a document ID obtained from another tool, or context like permissible document states.

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