Get registry stats

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered and the bar for the description is lower. The description adds value by enumerating which dimensions are aggregated, but says nothing about data freshness, caching, or whether the totals are global or scoped.

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?

A single dense sentence that front-loads the scope ('Totals across the AIDEN index') and then enumerates the returned dimensions. No filler, no repetition of the title, nothing that fails to earn its 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, so the description must carry the burden of saying what comes back, and it does list the five aggregate dimensions. It falls short only in not indicating the shape of the response (single object of numeric totals vs. nested breakdown) or whether values are counts versus currency.

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 and schema coverage is reported at 100%, so there is nothing for the description to disambiguate. With no parameters, the baseline of 4 applies and the description introduces no conflicting or confusing parameter claims.

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 concrete resource (the AIDEN index) and the exact aggregates returned (agents, owners, feedback, validations, settled USDG), which is far more specific than a tautological restatement of the title. It implicitly distinguishes itself from siblings like get_agent and get_agent_feedback, though it never explicitly contrasts with get_indexer_health, the closest neighbor.

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?

Usage is only implied: the name and description suggest a lightweight overview call, and a zero-parameter stats tool is nearly self-selecting. There is no explicit when-to-use statement, no mention of get_indexer_health as the alternative for health-style checks, and no stated prerequisites or exclusions.

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