Instructions

Returns the API's response resource as JSON — request body is a JSON Event object accepting anyoneCanAddSelf, attachments, attendees, attendeesOmitted, birthdayProperties, colorId, conferenceData, created and 36 more fields; pass it via params or whole via body_file Siblings over the same resource: delete, get, import, instances, list, move, patch, quickAdd, update, watch.

Input Schema

NameRequiredDescriptionDefault
queryNoExtra KEY=VALUE query pairs for endpoints whose parameters Discovery does not describe.
paramsNoParameter map merged into the request; typed parameters win.
dry_runNoReturn the request that would be sent, without sending it.
body_fileNoRead the request body from this file ('-' for stdin) instead of building one from the parameters. The body is a JSON Event object.
calendarIdYes[URL path segment] Calendar identifier. To retrieve calendar IDs call the calendarList.list method. If you want to access the primary calendar of the currently logged in user, use

Values: `all` = Notifications are sent to all guests.; `externalOnly` = Notifications are sent to non-Google Calendar guests only.; `none` = No notifications are sent. Warning: Using the value none can have significant adverse effects, including events not syncing to external calendars or events being lost altogether for some users. For calendar migration tasks, consider using the events.import method instead..

request_bodyNoRequest body of type Event: pass it via `params` (merged into the built body) or whole via `body_file`.

supportsAttachmentsNo[query parameter] Whether API client performing operation supports event attachments. Optional. The default is False.

  3. First observed

TDQS

A3.8/5.0
Behavior4/5

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

No annotations are provided, so the description carries the full burden, and it does disclose the key traits: this is a mutation ('creates or triggers a change'), it is 'refused under --readonly safety profiles', and it returns the API response resource as JSON. It stops short of noting side effects such as guest notifications being sent (that lives only in the sendUpdates schema description) or required auth scopes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The lead ('Creates an event — creates or triggers a change; refused under --readonly safety profiles') is well front-loaded, but the middle sentence enumerates nine verbose field names ('anyoneCanAddSelf, attachments, attendeesOmitted, birthdayProperties...and 36 more') that add no selection or invocation value and bloat an otherwise tight definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 12 params, a deep nested request body, an output schema, and no annotations, the description covers the essentials: mutation semantics, safety-profile refusal, body-passing mechanics, and sibling context. Minor gaps (guest notification side effects, auth requirements) remain, but the output schema and full param coverage carry the rest.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents every parameter including calendarId, sendUpdates, and the request body. The description adds only the mechanics of passing the body via `params` or `body_file`, which is largely restated in the request_body schema description — baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Creates an event') and explicitly says it is the create operation among siblings over the same resource. An agent can distinguish it from events.patch/update/import without opening a schema, aided by the explicit sibling enumeration.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description lists the sibling operations (delete, get, import, instances, list, move, patch, quickAdd, update, watch) but gives no routing rule — nothing says when to choose insert over import (e.g. migrations) or quickAdd (natural-language events). Usage is implied by the sibling list rather than stated.

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