Manage Event

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

Annotations already declare readOnlyHint=false, destructiveHint=true, openWorldHint=true, and idempotentHint=false; the description's create/update/delete operations are consistent with them, so there is no contradiction. Yet the description adds no behavioral context of its own — nothing about irreversibility of deletion, notification side effects, or the RSVP state change — leaving the annotations to carry the full burden.

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 sentences with zero filler, and the resource 'calendar events' is front-loaded. It is efficiently written, though for a 32-parameter, four-mode tool the description could carry more useful signal without becoming verbose.

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 tool this complex, the description is thin: it offers no usage routing, no authentication note, and no cross-action parameter guidance. The 100%-covered schema and the presence of an output schema compensate substantially, so the tool remains correctly invokable, but the description alone leaves an agent under-informed about prerequisites and action-specific expectations.

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 100% with detailed per-parameter docstrings (e.g., 'required for create', 'rsvp action only'), so the baseline of 3 applies. The description merely enumerates the four action values already defined in the schema and adds no additional parameter-level meaning.

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 identifies the resource ('calendar events') and the operations ('creating, updating, deleting, and RSVP'), which tells an agent this is the write/management tool for events rather than the read-only get_events. However, 'manages' is a generic verb and no sibling is named explicitly, so differentiation is conveyed only through the action list rather than a direct contrast.

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 operation list ('creating, updating, deleting, and RSVP') implies when the tool applies, which is the minimum viable usage signal. But the description gives no explicit when-to-use vs alternatives — notably get_events for reading, create_calendar for calendar-level work — and no mention of the start_google_auth prerequisite.

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