description: >-
  Odoo 19 development knowledge base with 18 specialized guides covering
  Actions (ir.actions.*, cron jobs, server actions), Controllers (HTTP
  routing, endpoints, auth types), Data files (XML/CSV records, shortcuts,
  noupdate), API Decorators (@api.depends, @api.constrains, @api.ondelete,
  @api.onchange, @api.model, @api.private), SQL Constraints (models.Constraint
  replacing _sql_constraints), Database Indexes (models.Index), Module
  development (manifest, wizards, reports), Field types (Char, Text, Monetary,
  relational fields), Manifest configuration (__manifest__.py, dependencies,
  asset bundles), Mixins (mail.thread, mail.activity.mixin, mail.alias.mixin,
  utm.mixin), ORM Model methods (search, CRUD, domain filters, recordsets,
  CamelCase model naming), Migration scripts (pre/post/end hooks, data
  migration), OWL frontend components (hooks, services, lifecycle),
  Performance optimization (N+1 prevention, batch ops, _read_group), QWeb
  Reports (PDF/HTML, paper formats, barcodes, t-out), Security/ACL (record
  rules, field permissions, privilege-based groups, @api.private), Testing
  (TransactionCase, HttpCase, mocking, query count assertions), Transactions
  (savepoints, UniqueViolation, serialization failures), Translations (i18n,
  PO files, translatable fields), XML Views (list/form/search, kanban card
  templates, xpath inheritance, QWeb templates). Use when writing, reviewing,
  or debugging any Odoo 19 Python or XML code, creating or modifying modules,

## Coding Conventions

Before writing code, run the `odoo-workflow` skill if it is installed (trace the real
source, Context Brief with `file:line`, definition of done); install it alongside this pack.

Read `references/api-highlights.md` before writing code and apply its Quick review
checks: the ❌ items are what not to use in Odoo 19.

Apply the convention section in the guide you open. Odoo 19 runtime behavior,
then existing stable-addon style, takes precedence; keep diffs focused.

- Module naming, assets, JavaScript, CSS, and SCSS: development guide.
- XML formatting and IDs: data, actions, reports, security, and views guides.
- Python, recordsets, transactions, and translations: model, field, decorator,
  performance, transaction, and translation guides.
