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

With no annotations, the description must carry the behavioral disclosure burden. It only says 'validate' and 'free', which implies a non-destructive check but gives no detail on failure behavior, side effects, or required permissions. The term 'free' is ambiguous and not explained.

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 extremely short, which is concise, but it is under-specified to the point of being insufficient. It lacks structure and fails to include necessary details. It is not efficiently written because it omits critical 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 complexity of an open-ended object parameter and no annotation coverage, the description is far from complete. It does not reference the v1 schema or the sibling tool 'honest_delivery_refusal_schema' that could provide schema details. An agent cannot correctly call this tool without additional information.

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 coverage is 0%, so the description must explain the 'refusal' parameter. It does not mention the parameter at all, nor the v1 schema structure. The schema only specifies an object with additionalProperties true, providing no guidance. The description adds zero value here.

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 verb 'validate' and the resource 'honest delivery refusal against the v1 schema', which is specific enough to distinguish from sibling validation tools (validate_relationship_memory, validate_tool_delivery_receipt). However, it does not explicitly differentiate from those siblings, so it misses the top score.

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 vs. alternatives, nor any prerequisites or context. It only states what it does, leaving the agent to infer usage from the name alone. No exclusions or alternatives are mentioned.

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