Create makes a new [Opening](/business/nouns/opening) from the inputs below. It is inherited: every [Noun](/business/nouns/noun) has `get`, `list`, `create`, `update` and `delete`.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `role` | [Role](/business/nouns/role) | Yes | The Role the Human joins, by taking a share of it. |
| `kind` | `string` | Yes | One of `floor`, `contractor`, `employee`, or `cofounder`. |
| `reason` | `string` | Yes | One of `floor`, `credential`, `edge`, `relationship`, `capital`, `capacity`, or `distribution`. |
| `hypothesis` | [Hypothesis](/business/nouns/hypothesis) | Yes | The result a hire must beat the incumbent Agent on. |
| `skills` | list of [Skill](/business/nouns/skill) | No | The Skills required, each citing the Evidence that shows the gap. |

| `opening` | [Opening](/business/nouns/opening) | Yes | The Opening. |

## Effects
- Emits `Opening.created`.
- Two-way: `try`, `send`, `do`.

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | [Opening.create](/business/nouns/opening/create) |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Low: two-way, nothing at stake |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | None: it runs once review passes. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
