delete_calendar_event

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

Annotations already flag destructiveHint=true, but the description goes further by stating the operation is IRREVERSIBLE and that it resolves `null` with a 204, i.e. no body is returned and there is no undo. That is genuine added context beyond the structured hints, though it says nothing about auth requirements or side effects on recurring events.

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?

Very short and front-loads the most important fact (irreversibility) before the technical detail. The word IRREVERSIBLE appears twice, which is mild redundancy, but the second instance is attached to an actionable instruction rather than pure repetition.

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 one-parameter destructive tool with no output schema, the description covers the essentials: it destroys data permanently, returns nothing (204), and requires user confirmation. Nothing critical to correct invocation is missing.

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 `eventId` parameter is documented as 'Numeric id'. The description mirrors this with the `{id}` path placeholder but adds no extra meaning such as accepted id sources or behavior for invalid ids, so baseline 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?

The description names the exact operation via the HTTP route `DELETE /calendar-service/event/{id}`, so the verb (delete) and resource (calendar event) are unambiguous even though the prose never spells out 'calendar event'. It does not distinguish itself from the many other `delete_*` siblings, but the operation itself is clear.

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 adds one real usage rule: 'confirm with the user before calling', which is a meaningful precondition for a destructive op. It gives no guidance on when to prefer deletion over `update_calendar_event`, nor any note about scope or dependencies, so usage is only implied by the name.

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