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

With no annotations, the description bears full responsibility for behavioral disclosure. It mentions the output format (CSV text) and fields, but does not disclose potential side effects, size limitations, or granularity of 'request history.' Basic behavior is clear but not deeply transparent.

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, front-loaded sentence: 'Export the full vendor document report as CSV text (vendor, doc type, due date, status, request history).' It includes the action, format, and content in a compact structure with no wasted words.

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 parameterless export tool with no output schema, the description adequately explains what is returned (CSV with listed columns) and that it is the 'full' report. It does not mention any limitations or edge cases, but the scope is simple enough that this is reasonably complete.

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 tool has zero parameters, so schema coverage is trivially 100%, triggering the baseline of 4. The description adds no parameter-specific semantics, but lists output fields, which is useful context though not parameter-related.

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 tool exports the full vendor document report as CSV text, with a specific verb (export), resource (vendor document report), and output format (CSV). It distinguishes from sibling tools like get_compliance_summary or list_missing_docs by emphasizing 'full' report.

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 use for complete report export (via 'full') but does not explicitly contrast with sibling tools such as search_vendor_docs or get_expiring_docs. No when-not guidance or alternative recommendations are provided.

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