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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context beyond annotations by disclosing the $0.001 USDC per-successful-call price and the HTTPS POST 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?

The description is front-loaded with the core purpose, followed immediately by helpful examples, the input constraint, and operational details. Every sentence adds information without repetition or filler.

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 simple one-parameter read-only tool with no output schema, the description provides the purpose, input range, example outputs, pricing, and alternate HTTPS access. This is enough for an agent to understand what the tool does and how to invoke 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?

Schema description coverage is 0%, so the description must carry parameter meaning. It does so by stating 'n runs from 1 to 20' and by giving concrete examples for n=1 and n=3, which clarify both the valid input range and how n maps to the comma-separated result.

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 clearly states that the tool returns the juggler path from n through 1 as a comma-separated string, with examples for n=1 and n=3. It is specific enough to distinguish the full-path resource from sibling tools like juggler_step or juggler_max, but it does not explicitly name or contrast those alternatives.

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 implied by the examples and the statement 'n runs from 1 to 20', which show how to invoke the tool and what output to expect. However, there is no explicit guidance on when to use this versus juggler_step, juggler_steps, juggler_max, or juggler_odd.

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