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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered externally. The description adds status context (free, beta, future paid tier) which is mildly useful, but it discloses nothing about limits, input expectations, or what the 'evidence categories' output actually contains.

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?

Two short sentences, so it is compact, but the second sentence is purely commercial-tier marketing rather than selection-relevant information. It is terse without being informative.

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?

There is no output schema, so the description carries the burden of explaining returns, yet 'evidence categories and interpretation notes' is left undefined. Combined with the undocumented input parameter, the definition is too thin for an agent to invoke confidently.

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 single 'text' parameter has no schema description (0% coverage) and the description never mentions it at all — it does not say whether text is a tender document, a query, or a URL. With low coverage and no compensating detail, the agent is left guessing what to supply.

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 names a recognizable activity (tender screening) and adds that it returns evidence categories and interpretation notes. However, it never explains what distinguishes it from its obvious sibling tender_preflight_basic, so an agent cannot tell the two apart from the text alone. The purpose is vague rather than specific about scope.

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?

There is no when-to-use guidance, no exclusions, and no named alternative despite the surrounding basic/evidence sibling pattern. 'FREE beta' and 'intended future paid tier' are commercial status statements, not usage instructions.

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