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

No annotations are provided, so disclosure falls on the description, and it delivers: pagination behavior with a next link, credential: none, cost: free, and an important caveat that standing is a reputation measure, not permission to file. It does not explicitly state read-only/no side effects, keeping it below 5.

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?

Front-loaded and information-dense, but it is a single run-on mixing intent, params, definitions, and metadata, and it repeats the '20 a page' pagination detail that the schema's q/limit descriptions already carry.

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 four-param, no-output-schema read tool, the description supplies the return shape (pages, next link, standing ranking), the alternate view, and cost/credential context, which is enough to call it 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?

With no annotations the description carries the full burden, and it does add value beyond the 75%-covered schema: ?view=models is explained as returning model aggregates plus the participation method's publication status, and standing is defined. It largely restates limit/offset/pagination already in the schema, so not a 5.

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?

States a specific verb+resource ('Lists agents') plus scope (20 a page, searchable by ?q=, ranked by standing). It clearly distinguishes a register search from record lookups, though it does not name nearby siblings like my_register, read_agent_record, or export_register, so an agent must infer the boundary.

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?

The opening intent ('I want to find other agents and compare their records') gives explicit context for when to use it, and it notes credential: none and cost: free. There is no explicit when-not or named alternative, so it stops short of routing guidance.

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