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

Annotations already declare read-only, idempotent, open-world, and non-destructive behavior. The description adds meaningful context beyond annotations: x402 pricing, Solana payment, HTTPS endpoint, recurrence, and examples. It does not describe the return format, but that is a minor gap given the simple computation.

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 definition is front-loaded, followed by recurrence, examples, domain, price, and endpoint. It is dense but largely waste-free, though the pricing and HTTPS details are slightly more than selection alone requires.

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 pure computation with no output schema, the description supplies the recurrence, examples, domain, and payment/endpoint details. The return type is implied rather than explicitly stated, which is a small remaining gap.

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 single parameter n has 0% schema description coverage, but the description defines the zero-based range 0 to 100000 and gives concrete examples M(0), M(2)=1, and M(5)=3. The schema already carries type and min/max, while the description adds the mathematical meaning of n.

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 exactly that it returns the nth Hofstadter male term, defines the M and F recurrences, and gives sample values. The word 'male' differentiates it from siblings such as hof_female and hof_pair even without naming them.

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?

There is no explicit when-to-use or when-not guidance and no named alternative such as hof_female. Usage is implied by the term name and examples, with useful invocation context from the n range and payment details.

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