## Why Fast instance commands run in the ArgoCD **PreSync** hook, before the new pods roll. A bulk `UPDATE`/`INSERT`/`DELETE` held in the **same transaction** as an `ADD COLUMN`/`ALTER` keeps an `ACCESS EXCLUSIVE` lock on the table for the whole write, blocking every read of it. That is what froze prod during the 2.13 `isUIReadOnly → isUIEditable` rename — a bulk `UPDATE "fieldMetadata"` inside the same `up()` transaction as the `ADD COLUMN`s → read timeouts → failed PreSync → aborted sync. @charlesBochet already caught this exact pattern by hand on #21527 ("data migration => make a slow instance command :)"). This turns that manual review into something CI enforces. ## What New oxlint rule **`twenty/no-data-mutation-in-fast-instance-command`**: - Flags statement-leading `UPDATE`/`INSERT`/`DELETE`/`MERGE` passed to `.query(...)` **inside `up()`** of a `*-instance-command-fast-*` file. - Allows: schema DDL (`ALTER`/`CREATE`/`DROP`); `ON DELETE CASCADE` / a column named `updatedAt` (not statement-leading, so never matched); rollback DML in `down()`; and data migrations in **slow** commands' `runDataMigration()`. - The error message points the author straight at the slow-command pattern. Enabled as `error` in `twenty-server`. ## Grandfathering Scoping to `up()` means **only one** existing file violates the rule: the already-shipped 2.13 rename command. It's recorded complete in cloud and must not be rewritten, so it's grandfathered with a documented file-level `oxlint-disable` (the comment makes clear it's an exception, not a precedent). The four other fast commands that contain DML keep theirs in `down()` and are correctly unaffected. ## Tests - 9 RuleTester cases — valid: DDL, FK cascade, `updatedAt`, `down()` DML, slow-command DML, non-upgrade files; invalid: `UPDATE`/`INSERT`/`DELETE` in `up()`. - Verified end-to-end with oxlint: a throwaway violating file → 1 error; all 141 upgrade-command files → 0 errors; full oxlint-rules suite 225/225; typecheck clean. Part of the v2.13 deploy post-mortem follow-ups. https://claude.ai/code/session_013Az1etaGyxWRRVhgjhPWeB --- _Generated by [Claude Code](https://claude.ai/code/session_013Az1etaGyxWRRVhgjhPWeB)_ <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/21547?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. --> --------- Co-authored-by: Claude <noreply@anthropic.com>

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
