Odoo Knowledge Agent - Error Prevention & Auto-Fix System

When to Use This Skill

Use this skill when you need to:

• Prevent Odoo errors before deployment with guardrails
• Auto-heal production issues using community-validated fixes
• Build intelligence from Odoo forum solved threads (1000+ cases)
• Generate error code reference and troubleshooting guides
• Create preventive checks for module development
• Implement auto-patch systems for known failure patterns
• Reduce debugging time by learning from community solutions
• Build SOP library for common Odoo development errors

Core Capabilities

1. Forum Scraping Intelligence

Scrape Odoo Forum for Solved Threads

• Extract 1000+ solved issues across all categories
• Parse accepted answers and code fixes
• Identify error patterns and root causes
• Build searchable knowledge base

2. Guardrails Generation

Preventive Error Checks

• Block common mistakes before deployment
• Validate manifest files automatically
• Check field synchronization issues
• Enforce best practices (OCA standards)

3. Auto-Patch Scripts

Automated Error Fixes

• Apply community-validated solutions
• Fix known issues automatically
• Handle common migration problems
• Self-healing production systems

4. Vision-Based UI Automation

askui-Compatible Automation

• UI actions without brittle selectors
• Cross-browser compatibility
• Screenshot-based validation
• Self-healing test scripts

Prerequisites

Examples

Example 1: Pre-Deployment Validation

# Check module before deployment
python guardrails/check_all.py ./custom_modules/expense_management

# Output:
⚠️ 3 issues detected:
  - [CRITICAL] GR-INSTALL-004: Invalid __manifest__.py (missing version)
  - [HIGH] GR-POS-001: POS field sync missing for 'receipt_url'
  - [MEDIUM] GR-ACCT-002: Invoice numbering using auto-increment

✅ Auto-fixes available for all issues. Apply? [y/N]

Example 2: Production Auto-Heal

# Monitor production for known issues
from odoo_knowledge_agent import ProductionMonitor

monitor = ProductionMonitor(odoo_db_uri)

# Detect issues
issues = monitor.check_for_known_issues()

# Auto-apply community-validated fixes
for issue in issues:
    if issue['confidence'] > 0.8:
        monitor.apply_fix(issue['fix_id'])
        monitor.log_fix(issue)

Example 3: Knowledge Base Search

# Search for similar issues
from odoo_knowledge_agent import KnowledgeBase

kb = KnowledgeBase(supabase_url, supabase_key)

# Semantic search using pgvector
similar_issues = kb.search(
    query="POS session won't close after adding custom field",
    limit=5
)

for issue in similar_issues:
    print(f"Thread: {issue['title']}")
    print(f"Solution: {issue['answer'][:200]}...")
    print(f"Similarity: {issue['similarity']:.2f}")

Cost Savings

vs. Manual Debugging

Activity	Manual Time	With Agent	Savings
Debug POS issue	4 hours	5 minutes	$150
Fix manifest error	1 hour	2 minutes	$40
Research solution	2 hours	Instant	$80

Monthly Savings (10 issues/month): $2,700
Annual Savings: $32,400

vs. Paid Support

• Odoo Partner Support: $5,000/year
• Self-Healing System: $0 (open source)
• Savings: $5,000/year

Total Annual Value: $37,400

Best Practices

Scraping Frequency

✅ Weekly updates: Keep knowledge base current
✅ Monitor new threads: Catch emerging patterns
✅ Version-specific: Filter by Odoo version

Guardrail Deployment

✅ Pre-commit hooks: Block bad code before commit
✅ CI/CD integration: Validate in pipeline
✅ IDE plugins: Real-time error prevention

Auto-Patch Safety

✅ Test in staging first: Never auto-patch production directly
✅ Version control: All patches in Git
✅ Rollback plan: Keep fix history

Troubleshooting

Scraping Blocked

Issue: Odoo forum blocks scraper IP
Fix: Use Firecrawl with rotating proxies, add delays

False Positives

Issue: Guardrail blocks valid code
Fix: Whitelist patterns, tune regex

Auto-Fix Breaks Code

Issue: Patch causes new errors
Fix: Improve test coverage, manual review high-risk fixes
