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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether this is a read or a mutation, not whether the agent must be registered first, not what the trust score range means, and not whether the score is cached or live.

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?

It is a single short tag-prefixed phrase with no waste, but the brevity comes from under-specification rather than tight writing; there is nothing front-loaded because there is nothing to front-load.

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?

With no annotations, no output schema, and no parameter documentation, the description leaves an agent unable to call this confidently or interpret the result. For a reputation/trust lookup it should at minimum state that it is a read and describe what score is returned.

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 is expected to compensate, but it says nothing about agent_id. The parameter name and example make the intent largely self-evident, but no format, lookup, or scoping semantics are added beyond the schema.

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 a resource (agent reputation/trust score) and the [agents] prefix ties it to the agents_* family, distinguishing it from the similarly named trust_score and receipt_reputation siblings. However, it states no verb, so an agent cannot tell whether this reads, computes, or updates a reputation 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?

There is no when-to-use guidance, no mention of prerequisites, and no routing hints toward alternatives such as trust_score, trust_history, or reputation_record. The agent must infer usage entirely from the tool name.

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