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

The description adds behavioral info beyond annotations: it creates payment links and can generate charges ('gera cobrança, mexe em dinheiro'). This provides context about financial impact, which annotations alone (readOnlyHint=false, destructiveHint=false) do not convey. No contradiction with annotations.

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 moderately concise but includes a list of five actions, most of which are irrelevant to this specific tool. The bullet list format is clear, but the inclusion of extra actions and the 'Flattened action' note add unnecessary complexity for a tool that only performs the create action.

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?

Given the lack of output schema and 0% schema coverage, the description should explain the full context: what the create operation returns, how to use parameters correctly, and the effect on the system. It only provides an overview of actions and minimal parameter info, leaving significant gaps for an agent to understand the tool's complete behavior.

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 0%, so parameters have no descriptions in schema. The description only vaguely explains the 'data' parameter for the create action ('data com a config do link'), but does not explain 'account' or 'payment_link_ucode'. This is insufficient for an agent to correctly supply parameter values.

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 states it handles mutations on Hotmart payment links and mentions creating a link as one action, but it also lists four other actions that are not relevant to this tool, causing ambiguity. The name 'write_create' and the flattened action note clarify it is for create, but the inclusion of other actions weakens clarity.

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?

No explicit guidance on when to use this tool vs sibling tools like hotmart_payment_links_write_add_offer. The 'Flattened action: create' note implies it's for create, but does not explain when this is appropriate or mention alternatives.

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