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

The description adds value beyond annotations: it explains that the action deletes the entry and cleans up counters, and that it only affects guest-list entries, not tickets. It also specifies the host requirement. This complements the destructiveHint=true annotation.

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?

Two sentences, no unnecessary words, front-loaded with the core action. Every sentence contributes meaningful information.

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 simple destructive nature and good annotations, the description is mostly complete. However, it lacks information about return values or behavior on failure/not found. For a delete operation, this could be considered a minor 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?

Schema description coverage is 0%, so the description must compensate. It mentions the required parameters (event_id, guest_id) but does not explain their semantics, format, or relationship beyond the names. The description provides minimal additional meaning over the schema.

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 clearly states the action (remove a guest-list entry), specifies the context (live event you manage), and distinguishes from purchased tickets. It also differentiates from siblings like edit_guest and add_guest.

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?

The description tells when to use (removing a guest-list entry) and when not to use (never purchased tickets). It also states prerequisites (event_id + guest_id, must be host). However, it does not explicitly name an alternative tool for removing tickets, but the 'only guest-list entries' serves as a clear exclusion.

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