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

Annotations already declare readOnlyHint=true, destructiveHint=false and idempotentHint=true, and the description reinforces this by stating it 'opens nothing by itself', which is the key behavioral fact for an agent tempted to assume it triggers a refund. It also discloses the shape of the return ('screens, buttons, fields') and names where the follow-up work happens, adding value beyond the structured fields, though it does not say how long or how structured that guidance is.

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 core operational sentence is front-loaded and efficient, but 'from ChatGPT, Claude or any AI agent' is marketing filler and the API version plus 'checked 31 Oct 2026' footnote is background trivia that does not change how an agent calls the tool. The useful content would fit in roughly half the length.

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 parameters and no output schema, the description carries the burden of explaining the return value, and it does so at a high level (step-by-step screens, buttons, fields) while pointing to the companion browser tools needed to act on it. It is close to complete for a guidance-only tool; a note on whether the guide is account-specific or generic would close the last 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?

There are zero parameters and the schema is fully closed (additionalProperties: false), so there is nothing for the description to disambiguate. Baseline for a parameterless tool applies, and the description correctly implies no inputs are needed by framing the call as 'just ask for the steps'.

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 a specific verb and resource (refund tickets in the user's Humanitix account) and then corrects the likely misreading of the tool name by clarifying that it returns a step-by-step how-to rather than performing the refund. That correction makes the actual purpose unambiguous, though the name humanitix_refund_tickets still implies an action, so a reader must finish the first sentence to be sure.

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?

It gives an explicit sequence: call this to get the steps, then execute them with the cotlet_browser_* tools in the user's Humanitix Cloud Browser. What's missing is any exclusion or routing rule against the other humanitix_* siblings (e.g., list_orders, stop_ticket_sales), so the agent must infer that those are direct-API actions while this one is guidance-only.

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