metering__verify_chain

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

With no annotations provided, the description must fully disclose behavior. It implies a read-only verification but does not mention side effects, return value, error conditions, or permission requirements. The agent is left guessing about output format and success criteria.

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 very short (one sentence plus a contextual prefix), which is efficient. It front-loads the namespace context, but the prefix could be seen as unnecessary overhead for the tool's core description.

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?

For a simple tool, key information is missing: what a meter is, what the chain comprises, and what the verification result means. Without output schema or annotations, the description leaves significant gaps for an agent to use the tool correctly.

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 entirely omits explanation of the 'meter_id' parameter (e.g., what it represents, how to obtain it, format constraints). The agent cannot infer the correct value without external knowledge.

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 action ('Verify') and resource ('tamper-evident event hash chain for a meter'), with a contextual prefix that distinguishes it from sibling verify tools in other namespaces.

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 guidance on when or why to use this tool versus alternatives (e.g., other metering tools or verification tools). The description does not specify prerequisites or expected input context.

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