Odoo OWL

Use this skill for OWL frontend work in Odoo addons or standalone Owl applications.

First Move

Do not assume OWL 3. First detect the actual OWL/Odoo frontend version from local source and project code:

• Odoo version from branch, manifests, docs, or config.
• Local OWL source under $ODOO_SOURCE when set, especially addons/web/static/lib/owl or equivalent.
• Existing imports from @odoo/owl, owl, @web/*, and local frontend conventions.
• Asset declarations in __manifest__.py and existing static/src/js, static/src/xml, and static/src/scss patterns.

Use the OWL 3 references only when the target project actually uses OWL 3. For older Odoo versions, local source and existing project conventions supersede this skill's OWL 3 notes.

Route The Task

• Build or change OWL components: use OWL3-CORE.md, OWL3-TEMPLATES.md, and OWL3-STATE-LIFECYCLE.md.
• Integrate with Odoo assets/web client: use OWL3-ODOO-INTEGRATION.md and ASSETS.md.
• Build or review field widgets: use FIELD-WIDGETS.md.
• Migrate OWL 1/2 code toward OWL 3: use OWL3-MIGRATION.md, but verify local compatibility first.
• Review frontend guideline/style concerns: compose with odoo-code-review.
• Debug broken Odoo frontend behavior: use OWL-DEBUGGING.md, compose with odoo debugging workflow, and inspect browser/asset/test seams.
• Test OWL components, widgets, services, and registries: compose with odoo-web-testing and OWL-TESTING.md.

Always Apply

Keep UI state explicit and reactive. Prefer small components with clear props and events. Avoid mutating props. Clean up listeners and external resources with lifecycle hooks. Treat unsafe HTML as a security boundary. Verify asset bundle registration and template loading before blaming OWL behavior.
