Use the local Odoo source when $ODOO_SOURCE is available. Otherwise verify
version-sensitive examples against the official Odoo 20 source and
documentation before applying them to a module. Existing project conventions
and the target checkout take precedence over this reference pack.
The guide taxonomy follows these Odoo 20 source areas:
odoo/models.py - ORM implementationodoo/fields.py - Field typesodoo/api.py - Decoratorsodoo/http/ - HTTP layer internals; use public odoo.http APIs in addonsodoo/exceptions.py - Exception typesodoo/tools/translate.py - Translation systemodoo/addons/base/models/res_lang.py - Language modeladdons/web/static/src/core/l10n/translation.js - JS translationsOdoo 20 release-note-sensitive areas include Python 3.12+/PostgreSQL 16+, ir.access domains, access APIs, group privileges, OWL 3/frontend testing, website Interaction classes, engine-based reports, mail tracking, Material Symbols, offline web behavior, translation-aware import/export, and website/portal URL/form/SEO behavior. Read the relevant reference guide before applying older-version snippets.
For website and portal work, also compose this skill with odoo-website,
odoo-web-security, and odoo-web-testing.

Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallise. Use when the user wants to stress-test a plan against their project's language and documented decisions.

Find deepening opportunities in a codebase, informed by the domain language in CONTEXT.md and the decisions in docs/adr/. Use when the user wants to improve architecture, find refactoring opportunities, consolidate tightly-coupled modules, or make a codebase more testable and AI-navigable.

Odoo engineering workflows for addon development, codebase exploration, debugging, architecture/refactor review, manifest/docs sync, and routing to migration work. Use when the user mentions Odoo, addons, modules, manifests, models, XML views, security CSVs, record rules, Odoo shell, OWL/QWeb/assets, or when an Odoo codebase is detected.
