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

With no annotations, the description carries the full behavioral burden. "Public" weakly implies no credentials are required and "honest" implies trustworthy/raw data, but there is no disclosure of cost, rate limits, latency, caching, or what the payload contains.

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 phrase with no filler sentences, so it is not bloated. However, the brevity comes from omission rather than efficiency, and the vague adjectives do not earn their place.

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?

There is no output schema and no annotations, so the description is the only source of information about this tool. It never says what the metrics are, what form the result takes, or when an agent should call it, leaving the definition materially incomplete.

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 tool takes zero parameters, so per the baseline there is nothing for the description to clarify. No penalty applies here.

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?

"AETHER metrics" essentially restates the tool name aether_stats; there is no verb and no indication of which metrics (identity counts, relationship stats, usage?). The adjectives "public, honest" add tone but not a distinguishable purpose, and nothing separates it from siblings like aether_identity or aether_relationship_status.

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 when-to-use, no when-not-to-use, and no mention of any alternative tool. "Public" is the only hint and it is about access, not invocation context.

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