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

With no annotations, the description must carry the behavioral burden; 'Return' does communicate a read-only retrieval behavior. Yet it does not disclose what the value model contains, whether parameters filter or influence output, or any side effects, so transparency is adequate but shallow.

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 sentence with no filler and puts the action first. It is appropriately short, though the brevity borders on under-specification rather than elegant conciseness.

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?

With six optional parameters, zero schema descriptions, and no usage guidance, the description alone is insufficient for correct invocation. The existence of an output schema reduces the need to describe return values, but the missing parameter semantics and absent filter behavior still leave material 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?

Schema description coverage is 0%, and the description does not mention any of the six parameters. The nullable, optional identifier fields such as wedge_id, driver_id, segment_id, question_id, and scenario_id are left entirely unexplained, so the agent cannot determine their meaning or how they affect the returned model.

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 specific action ('Return') and a specific resource ('secure context value model') with a domain context ('buyer, ROI, and acquisition diligence'). It distinguishes itself from siblings like attestation, evidence, and trust packs, though the term 'value model' remains somewhat undefined.

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?

It implies when to use it: when a value model for buyer, ROI, or acquisition diligence is needed. However, it does not provide explicit when-not-to-use guidance or name alternatives from the large recipes_secure_context family, leaving selection partly to inference.

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