owp_scope_compare

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It implies a read-only comparison but does not explain what 'compare' means operationally, whether there are side effects, what kinds of mismatches are reported, or whether expected observations need a specific format.

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 concise sentence with no filler, repetition, or unnecessary details. It is front-loaded with the action and clearly states the two inputs, earning every word.

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 tool is simple with two string parameters and an output schema present, so the description is minimally complete for basic invocation. However, without annotations or usage guidance, the description does not fully equip an agent to understand comparison semantics or when this is the correct tool among the many sibling validation 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?

Schema description coverage is 0%, so the description must compensate for the unannotated parameters. It does help by suggesting scope_json maps to the signed scope and observed_scope_json maps to the verifier observation, but it adds no detail about JSON structure, encoding, or how the v0.3 version applies to the parameters.

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 uses a specific verb ('Compare') and identifies the resources ('a signed v0.3 scope' and 'one verifier observation'), which clearly differentiates it from most siblings like owp_scope_validate or owp_integrity_observation_validate. The version qualifier 'v0.3' adds useful precision, though 'verifier observation' is somewhat domain-specific and could be clearer.

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 guidance about when to use this tool versus alternatives such as owp_scope_validate or other observation-validation tools. The description states what the tool does but provides no context on prerequisites, selection criteria, or when it should be avoided.

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