vibo_leave_event

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

The 'confirm-gated' phrase discloses the confirmation behavior beyond the annotation's readOnlyHint=false. No contradictions; it adds useful context about the mutation.

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 short, direct sentences convey the essential information with zero waste. Perfectly front-loaded.

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 simple mutation tool with two parameters and no output schema, the description and schema together cover all necessary aspects: what action, on which resource, and with what safeguard.

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% with clear parameter descriptions. The description repeats the confirmation gate but adds no new details beyond the schema, so baseline 3 is appropriate.

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 verb 'Leave' and the resource 'event', and the phrase 'you previously joined' distinguishes it from joining or viewing events.

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 indicates when to use (leaving a joined event) and the 'confirm-gated' note gives guidance on required confirmation. It implicitly excludes non-joined events but does not list alternatives.

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