# Remember something

> Save something to memory that the next agent working here should know: how to build or test, a convention, a decision and why, a trap. scope project is for this codebase; scope workspace is for what holds across all of the workspace's projects, such as "we use pnpm everywhere" or where staging lives.

<div class="g1t-endpoint"><span class="g1t-method" data-method="post">POST</span><code>/repos/{owner}/{name}/memory</code></div>

One short fact per memory. Every g1t agent run is given memory at its start, pinned first. Never save a secret, key, token or password: text that looks like one is refused. Members of the workspace and g1t's agents only.

Text that looks like a key, a token or a password is refused with `invalid`: memory is read by every agent in the workspace. Saving the same text again in the same scope returns the memory already kept.

- **Authentication:** Required. Send an [access token](/reference/api/#authentication) as `Authorization: Bearer`.
- **MCP tool:** [`memory`](/reference/mcp/#memory) with `action` `remember`, and the same inputs
- **Scope:** An access token needs [`memory:write`](/guides/authentication/#scopes).

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `text` | string | Yes | What to remember, in one or two sentences. At most 1000 characters. |

## Example request

```sh
curl -X POST https://api.g1t.sh/repos/flagon-io/hello/memory \
  -H "Authorization: Bearer $G1T_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "The tests need TZ=UTC or the date tests fail.",
    "scope": "project",
    "kind": "gotcha",
    "from_number": 14
  }'
```

## Errors

A failed request answers with one of these statuses and a body like `{"error": {"code": "not_found", "message": "Repository not found."}}`. See [errors](/reference/api/#errors).

| Status | Code | When |
| --- | --- | --- |
| 401 | `unauthenticated` | A token is required, or the one sent is not valid. |
| 403 | `forbidden` | The token is valid but not allowed to do this, such as a member-only change or an agent token outside its repository. |
| 404 | `not_found` | It does not exist, or you cannot see it. |
| 409 | `conflict` | The request conflicts with the current state. |
| 422 | `invalid` | The input is not valid. `message` says which field and why. |
