kappa 860e36a688 feat: add memory system and troubleshoot agent
Memory System:
- Add category-based memory storage (company, tech, role, location, server)
- Silent background saving via saveMemorySilently()
- Category-based overwrite (same category replaces old memory)
- Server-related pattern detection (AWS, GCP, k8s, traffic info)
- Memory management tool (list, delete)

Troubleshoot Agent:
- Session-based troubleshooting conversation (KV, 1h TTL)
- 20-year DevOps/SRE expert persona
- Support for server/infra, domain/DNS, code/deploy, network, database issues
- Internal tools: search_solution (Brave), lookup_docs (Context7)
- Auto-trigger on error-related keywords
- Session completion and cancellation support

Database Migrations

This directory contains database migration scripts for the Telegram Bot Workers project.

Files

File Purpose
001_schema_enhancements.sql Migration script - adds CHECK constraints and audit logging
001_rollback.sql Rollback script - reverts migration 001
AUDIT_LOG_EXAMPLES.ts TypeScript examples for using audit logs
TEST_RESULTS.md Local test results and verification
README.md This file

Quick Start

Local Testing

# Initialize local database
npm run db:init:local

# Add test data
wrangler d1 execute telegram-conversations --local \
  --command "INSERT INTO users (telegram_id, username) VALUES ('123', 'test')"

# Run migration
wrangler d1 execute telegram-conversations --local \
  --file migrations/001_schema_enhancements.sql

# Verify constraints work
wrangler d1 execute telegram-conversations --local \
  --command "INSERT INTO user_deposits (user_id, balance) VALUES (999, -1000)"
# Expected: CHECK constraint failed

Production Deployment

⚠️ MANDATORY: Read SCHEMA_MIGRATION_GUIDE.md first

# 1. Backup database
wrangler d1 execute telegram-conversations \
  --command ".dump" > backup_$(date +%Y%m%d_%H%M%S).sql

# 2. Run migration
wrangler d1 execute telegram-conversations \
  --file migrations/001_schema_enhancements.sql

# 3. Verify success
wrangler d1 execute telegram-conversations \
  --command "SELECT 'Migration completed' as status, datetime('now') as timestamp"

Migration 001: Schema Enhancements

Date: 2026-01-19

Changes

  1. user_deposits: Add balance >= 0 CHECK constraint
  2. deposit_transactions: Add depositor_name length <= 50 CHECK constraint
  3. audit_logs: Create new table for operation tracking

Benefits

  • Prevent negative balances at database level
  • Enforce depositor name length limit
  • Track all critical operations for compliance and debugging
  • Improved data integrity and auditability

Risk Level

  • Low: No breaking changes to application code
  • No downtime: Migration completes in < 1 second for typical datasets
  • Reversible: Rollback script available

Files

  • Migration: 001_schema_enhancements.sql
  • Rollback: 001_rollback.sql
  • Guide: ../SCHEMA_MIGRATION_GUIDE.md
  • Examples: AUDIT_LOG_EXAMPLES.ts
  • Tests: TEST_RESULTS.md

Documentation

For detailed information, see:

  • SCHEMA_MIGRATION_GUIDE.md: Complete deployment guide
  • TEST_RESULTS.md: Local test results and verification
  • AUDIT_LOG_EXAMPLES.ts: Usage examples for audit logs

Support

If issues occur during migration:

  1. Check logs: wrangler tail
  2. Review SCHEMA_MIGRATION_GUIDE.md troubleshooting section
  3. Rollback if necessary: 001_rollback.sql
  4. Restore from backup if critical failure
