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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe/public-read profile is covered. The description adds genuine behavioral context beyond that: the ordering rule ('featured agents first'), the ranking dimensions, and that access is free (no auth/cost barrier). It does not explain pagination or what happens when limit is omitted, which leaves some gaps for a list endpoint.

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 front-loads the resource and then lists the ranking criteria, with no filler. The trailing 'Free' is a little abrupt but carries real information. Sized appropriately for the tool's simplicity.

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 one-parameter read tool with no output schema, the description covers what is ranked and in what order, and annotations cover safety. However, it omits the limit parameter and gives no hint of the return shape or default page size, leaving the agent guessing about the response. Adequate but with clear gaps.

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?

There is a single parameter, limit, with 0% schema description coverage, so the description must carry the burden of explaining it. The description never mentions limit at all, leaving its range, default, and effect on the ranking unexplained. With one undocumented parameter, the definition fails to compensate for the coverage gap.

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 specific resource (agents and desk strategies sold on OwlChart) and characterizes it as a public ranking by sales, usage, verified desk hit rate and member ratings, with featured agents first. This is clearly a leaderboard rather than a raw product list like get_desk_strategies or a single-agent report like get_track_record. It stops short of explicitly contrasting itself with those siblings, so it earns a 4 rather than a 5.

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 description says the data is public and free, which implies an open read use case, but never states when to reach for this tool versus get_desk_strategies, get_owl_score, or get_track_record. There are no prerequisites, exclusions, or alternative-routing hints, so an agent must infer the use case from the ranking criteria alone.

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