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

Annotations already declare readOnly, idempotent, non-destructive, non-open-world behavior, so the safety profile is covered. The description adds real value beyond that by enumerating what the response contains (what you sell, earnings note, setup, rules, stop rule, risks, public link), which is otherwise undocumented since there is no output schema.

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?

One front-loaded sentence that leads with the purpose before the parenthetical clarification. It is a long enumerated list, but every element maps to content the agent needs, so little is wasted.

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?

With no output schema, the description carries the burden of describing the return payload, and it does so by listing the guide's sections and the public link. Combined with the search_ways provenance, an agent has enough to call it correctly and know what to expect back.

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 coverage is 100% and the single parameter is already documented with an example and the 'part of its name' flexibility. The description mostly repeats this ('id from search_ways, or its name'), adding only the provenance detail about where the id comes from, so the baseline of 3 applies.

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 and resource ('Full detail for one way to earn') and immediately disambiguates from the sibling search_ways by noting the id originates there. An agent can distinguish it from search_ways and get_platform_rules without opening any schema.

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?

Explicitly signals the workflow context ('id from search_ways'), telling the agent this is the follow-up to a search. It does not state when-not to use it or how it differs from get_platform_rules, even though it claims to include 'the platform rules', which leaves slight overlap ambiguity.

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