owp_control_observation_validate

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

Even with no annotations, the description discloses critical behavior: it never signs, commits, accepts, or settles, and it reports signer authority as not_checked, never authorized. This clearly communicates what the tool does not do and what limitation exists.

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?

Three short sentences, first sentence introduces the core purpose, remaining sentences add essential safety semantics. No wasted or redundant text.

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?

The description is mostly complete for a single-parameter validation tool with an output schema: it conveys purpose, read-only nature, and the signer-authority limitation. It falls short only in parameter guidance and explicit mention of when to prefer this over sibling tools.

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?

There is one required parameter, payload_json, with 0% schema description coverage. The description implies the payload is the control observation set, but does not explain the expected JSON structure, required fields, or encoding, so it does not compensate for the missing parameter documentation.

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 the specific resource: one v0.5 control observation set, and the action: assess against contracts. This clearly distinguishes it from siblings like owp_integrity_observation_validate by the resource type and version.

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 read-only statement provides clear contextual guidance: this tool can validate without side effects. It does not explicitly list when not to use it or name alternatives, so it stops short of a full 5.

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