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

The annotations already declare readOnlyHint=true and destructiveHint=false, but the description adds the genuinely important fact that the tool 'opens nothing by itself' and only returns screen/button/field instructions. That is behavior an agent could not infer from the annotation booleans alone. It does not mention limits such as whether the guidance is event-scoped or what happens if the user lacks permissions.

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 operative content is front-loaded and clear, but the sentence 'from ChatGPT, Claude or any AI agent' is marketing filler, and the closing note about Humanitix's public API v1.29.3 and the 'checked 31 Oct 2026' timestamp adds nothing an agent needs to select or invoke the tool.

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 zero-parameter tool with no output schema, the description covers what an agent needs: what it returns (step-by-step screens/buttons/fields) and that nothing is executed. The only gap is that it does not describe how the returned guidance is scoped or formatted.

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, so the baseline applies; nothing in the schema needs explaining. The description does not need to add parameter meaning, though it could have noted that the target event/user context comes purely from ambient session state.

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 names a specific verb and resource (create complimentary order in the user's Humanitix account) and immediately clarifies the surprising twist that it returns a step-by-step guide rather than performing the write. That clarification separates it from the humanitix_* action siblings such as humanitix_refund_tickets or humanitix_create_discount_code.

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 explicitly hands off the actual execution to 'the cotlet_browser_* tools in the user's Humanitix Cloud Browser', which is concrete when-to-use-which guidance for the follow-up step. It does not state any exclusion condition (e.g. when to prefer a different order-creation path), so it stops short of full 5-level routing.

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