Delete a task or meeting

delete_agenda_item
Destructive

Delete a task or meeting by id. A meeting in Google Calendar is deleted there too (the attendees are told). Confirm with the user first.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "id": "<id>"
    },
    "name": "delete_agenda_item"
  }
}

Input Schema

NameRequiredDescriptionDefault
idYes
idempotencyKeyNoOptional. A unique id for this action (16-128 chars: letters, digits, _ : . -). If you are unsure whether a call went through (timeout, network error), repeat it with the SAME idempotencyKey and the same arguments: you get the original result and nothing is done twice.

A4/5.0
Behavior4/5

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

Annotations already flag destructiveHint=true and openWorldHint=true, but the description adds specifics they don't convey: the linked Google Calendar meeting is deleted externally and attendees are notified. That external side effect is exactly the kind of context an agent needs before deleting. It doesn't cover failure modes (e.g., nonexistent id) but adds real value beyond the annotations.

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

Conciseness5/5

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

Three short sentences, front-loaded with the action and identifier, then the external side effect, then the safety rule. No filler and nothing that could be trimmed without losing meaning.

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?

For a destructive, externally visible mutation with no output schema, the description covers the essential elements: what is removed, the calendar-side effect, attendee notification, and the confirmation requirement. Minor gaps remain around error behavior and any dependent resources, but the critical information is present.

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 coverage is only 50%: idempotencyKey is fully documented in the schema, while 'id' has no schema description. The description's 'by id' is the only semantic hint for the identifier and adds little beyond the parameter name, but the tricky retry parameter is well handled by the schema itself.

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 ('Delete a task or meeting by id') and disambiguates the vague term 'agenda item' into task/meeting, which distinguishes it from the delete_catalog_item and update/get_agenda_item siblings.

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?

Gives one concrete usage rule ('Confirm with the user first'), which is genuinely useful for a destructive action. However, it offers no when-not guidance or routing to alternatives such as update_agenda_item for modification, so an agent must infer the rest.

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