# Create an agent

`POST /agents`

Create an agent in the environment. Only `name` and `instructions` are required — `cadence` defaults to `manual`, which runs only when triggered via `POST /agents/{id}/runs`. Scheduled cadences require their time fields: `minute` for hourly, plus `hour` for daily/weekdays, plus `day_of_week` for weekly.

## Request body

- object
  - `name` string, required — Unique within the environment
  - `description` string
  - `instructions` string, required — The standing prompt every run executes
  - `model` string — Explicit model override. Omit to follow the platform default.
  - `cadence` 'manual' | 'hourly' | 'daily' | 'weekdays' | 'weekly'
  - `hour` integer
  - `minute` integer
  - `day_of_week` integer — 0 = Sunday
  - `timezone` string — IANA timezone the schedule is evaluated in
  - `active` boolean
  - `handles_file_drops` boolean — At most one active agent per environment can have this enabled
  - `delivery_enabled` boolean
  - `delivery_recipients` string[]
  - `delivery_file_pattern` string
  - `mentions` object[]
    - `type` 'reconciliation' | 'data_stream' | 'user', required
    - `id` string, required
    - `label` string, required
