| Origin hint   | core is Weaviate Database. A client short name such as py means the message was raised before the request left your application. |
| Category hint | The topic: mem for memory, dep for a deprecation, auth for authentication.                                                       |
| Number hint   | Unique within its origin and category.                                                                                           |

Ids are permanent. The message text and the page it points to can both change, but an id that shipped in a release keeps meaning the same thing forever, so it is safe to search for, to alert on, and to quote in a support ticket.

:::callout{intent="note" title="Bare legacy ids"}
Released Python clients print the id without the origin, so what you see today is `Dep024`, not `py-dep024`. Both forms lead to the same entry, and bare ids are never reassigned.

## Missing an entry?

This section is being filled in message by message. An id whose entry is not written yet lands you on this page rather than on a dead link. Every id printed by a released version has an entry planned. Until it exists, quote the id in a [support request](../support/overview.md); it names the message exactly.

:::callout{intent="info" title="Rolling out"}
The `docs_url` field and the link suffix ship with Weaviate Database v1.40. The Python client prints a bare id such as `Dep024` today, and the other clients none yet. The messages themselves are not new: the entries describe what current releases already print.

# Agent Instructions

This portal answers questions programmatically. To receive a synthesized,
source-cited answer instead of crawling page by page, append the `?ask=`
query parameter to any page URL on this site:

    /guides/quickstart?ask=how+do+I+authenticate

Optional parameters:

- `&goal=<what-you-are-trying-to-do>` steers the answer toward your
  objective (e.g. `&goal=write+a+python+client`).
- `&version=<label>` scopes the answer to a mounted version when the
  portal publishes more than one.

The response is `text/markdown`: the answer followed by a `# Sources` list
of the portal pages it was grounded in. Status codes are the contract:

- `200` — the answer; `402` — the portal owner’s plan or answer credits are
  exhausted (surface this to your operator; do NOT retry); `429` — you are
  rate-limited; back off for the `Retry-After` seconds; `503` — the answer
  lane is temporarily unavailable; fall back to crawling the `.md` pages.

For the full corpus map read `llms.txt` at the site root; for the tool
surface (search + page fetch as MCP tools) see `/mcp`.
