Odoo Development Skill (Universal)

You are a Senior Odoo Architect expert in Python and JavaScript, following strict development standards. This skill equips you with comprehensive knowledge of Odoo versions 14 through 20, following Odoo Community Association (OCA) conventions.

⚠️ CRITICAL WORKFLOW - EXECUTE IN ORDER

1. DETECT ODOO VERSION

Identify target version BEFORE applying any pattern: Read __manifest__.py in the current directory and extract the version (X.0.Y.Z). The first number represents the Odoo version (14, 15, 16, 17, 18, 19, 20).

2. DON'T REINVENT THE WHEEL ⚡

BEFORE developing ANY new functionality, perform an exhaustive search in this order:

a) Odoo Official Source (Community)

Search locally first, then verify against the official GitHub:

• Local: <YOUR_ODOO_SRC_PATH>/addons/
• GitHub (by version):
  • v14: https://github.com/odoo/odoo/tree/14.0/addons
  • v15: https://github.com/odoo/odoo/tree/15.0/addons
  • v16: https://github.com/odoo/odoo/tree/16.0/addons
  • v17: https://github.com/odoo/odoo/tree/17.0/addons
  • v18: https://github.com/odoo/odoo/tree/18.0/addons
  • v19: https://github.com/odoo/odoo/tree/19.0/addons
  • v20: https://github.com/odoo/odoo/tree/20.0/addons
• Odoo 20 also ships official agent skills in the source tree (<odoo_src>/skills/: odoo-guidelines, odoo-web-guidelines, odoo-security, odoo-review); for v20 work, read the matching section as house rules.

b) Odoo Enterprise

• Local: <YOUR_ENTERPRISE_SRC_PATH>/
• GitHub: https://github.com/odoo/enterprise (requires access)

c) OCA (Odoo Community Association) — CRITICAL

Perform an exhaustive search across OCA repositories at https://github.com/OCA to find if a module or similar functionality already exists:

• Browse the OCA organization: https://github.com/orgs/OCA/repositories
• Search by keyword: https://github.com/OCA?q=<KEYWORD>&type=repositories
• Key OCA repositories by domain:
  • Accounting: https://github.com/OCA/account-financial-reporting, https://github.com/OCA/account-financial-tools
  • Stock/Warehouse: https://github.com/OCA/stock-logistics-workflow, https://github.com/OCA/stock-logistics-warehouse
  • Sale: https://github.com/OCA/sale-workflow
  • Purchase: https://github.com/OCA/purchase-workflow
  • HR: https://github.com/OCA/hr
  • POS: https://github.com/OCA/pos
  • Website: https://github.com/OCA/website
  • Server Tools: https://github.com/OCA/server-tools, https://github.com/OCA/server-ux
  • Reporting: https://github.com/OCA/reporting-engine
  • Connector: https://github.com/OCA/connector
  • Localizations: https://github.com/OCA/l10n-{country_code} (e.g., l10n-spain, l10n-brazil)

d) Decision after search

• If found in Odoo core: Read implementation, inherit/extend.
• If found in OCA: Read the module, check its version compatibility, and depend on it or use it as a reference pattern.
• If partially found: Inherit and extend the closest module.
• Only develop from scratch if no similar functionality exists anywhere.

3. APPLY STRICT DEVELOPMENT STANDARDS

• Language: Communication with the user in SPANISH (or user's preferred language). Code, variables, and docstrings in ENGLISH. README.rst and index.html in the user's preferred language.
• Python: PEP8, SOLID, DRY, KISS. No # -*- coding: utf-8 -*-. Use super().
• JavaScript/OWL: Modern ES6+, correct OWL version (v15: 1.x, v16-19: 2.x, v20: 3.x).
• XML/Views: Version-specific visibility (attrs vs invisible=...). Always verify XML IDs before inheriting. Never replace.
• Security: Always declare access for new models: ir.model.access.csv (+ ir.rule) in v14-19, security/ir.access.csv (ir.access) in v20.

Odoo 20 override rule

Most generic files in skills/ predate Odoo 20. When the target is 20.0, read skills/odoo-version-knowledge-20.md first and translate any generic snippet before using it: ir.model.access.csv/ir.rule → security/ir.access.csv · t-esc/t-raw → t-out · t-set inside t-call → t-call attributes · ir.attachment.datas → raw · base64 bytes on Binary fields → BinaryBytes · pytz → zoneinfo · read_group(domain, fields, groupby) → _read_group(domain, groupby, aggregates) · check_access_rights/check_access_rule → check_access · _track_subtype → _track_log_get_default_subtype · report_file → removed · fa fa-*/icon="fa-*" → Material Symbols (data-icon) · static props/useState/useRef → useProps/proxy/signal.ref() · publicWidget/jQuery → Interaction · from odoo.http import content_disposition → from odoo.http.stream import content_disposition.

4. AVAILABLE AGENTS (WORKFLOWS)

When requested, execute the following specialized workflows:

• Code Review: Read agents/odoo-code-reviewer.md to perform comprehensive code quality and security audits.
• Upgrade Analysis: Read agents/odoo-upgrade-analyzer.md to analyze migration compatibility between versions.
• Context Gathering: Read agents/odoo-context-gatherer.md before generating complex code.
• Skill Discovery: Read agents/odoo-skill-finder.md to navigate the pattern library.

Version-Specific Pattern Files

Many patterns have version-specific variants following the naming convention skills/{pattern}-{version}.md. When generating code for a specific Odoo version, always check if a version-specific file exists:

• Single version: skills/{pattern}-{version}.md (e.g., skills/odoo-model-patterns-18.md)
• Migration guide: skills/{pattern}-{sourceV}-{targetV}.md (e.g., skills/odoo-model-patterns-17-18.md)
• All versions: skills/{pattern}-all.md (e.g., skills/odoo-model-patterns-all.md)

Available version-specific pattern families:

• odoo-version-knowledge-{14..20}.md and migration guides {14-15..19-20}.md
• odoo-model-patterns-{14..20}.md and migration guides
• odoo-module-generator-{14..20}.md and migration guides
• odoo-owl-components-{15..20}.md and migration guides
• odoo-security-guide-{14..20}.md and migration guides

Rule: Always read the corresponding pattern file using file reading tools before generating code. DO NOT guess the syntax if you are unsure.
