owp_integrity_observation_validate

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

With no annotations present, the description carries the burden and does well by explicitly stating 'This read-only tool never signs, commits, accepts, or settles anything' and that 'Signer authority is reported as not_checked, never as authorized.' These are meaningful behavioral constraints beyond the basic assess action.

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 highly compact: one purpose sentence followed by two short behavioral clauses. Every sentence contributes new information, and there is no fluff or repetition.

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 tool's low complexity—one parameter, an output schema, and no annotations—the description provides solid coverage by clarifying the read-only nature and signer authority behavior. The main gap is the lack of parameter format details, but the output schema compensates for return-value expectations, making the description 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 only parameter `payload_json` has no schema description and 0% description coverage. The tool description never names the parameter or explains its required JSON structure, only indirectly implying that the payload is the population observation set. This leaves the agent without enough information to correctly construct the input.

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 opens with a specific verb 'Assess' and a precise object: 'one v0.5 population observation set against its contracts.' This differentiates it from sibling tools like owp_control_observation_validate, which presumably handles control observations, and clearly states both the resource and the action.

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?

No explicit guidance is given for when to use this tool versus alternatives. The read-only note is behavioral, not a usage instruction, and no sibling tool is mentioned as an alternative or exclusion case. The description only restates the tool's core purpose.

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