refactor: Update prompts and descriptions for clarity and efficiency in the MCP Agent Orchestrator 

- Revised agent prompts to enhance clarity and token efficiency.
- Added specific instructions regarding task distribution and project rules for Backend, DB, and Frontend agents.
- Included warnings for users about the appropriate use of parallel_ask and task handling.
- Updated the overall structure and content of prompts to align with project requirements and improve user guidance.

# Available Tools # Available Tools

# Work Process # Work Process
1. Analyze request -> identify scope
2. If cross-domain (FE+BE+DB): use parallel_ask
3. If single domain: use specific agent
4. Integrate results -> report to user
## Phase 1: Analysis # Task Distribution
1. Analyze user request - Backend Agent: backend-node/src/ (controllers, services, routes)
2. Identify required information - DB Agent: db/, mapper/ (schema, migrations, queries)
3. Request info gathering (use parallel_ask) - Frontend Agent: frontend/ (components, pages, lib)
## Phase 2: Planning # Response: Always concise! Summarize key findings only.`;
1. Analyze gathered information
2. Break down tasks and identify dependencies
3. Determine priorities
4. Create work distribution plan
## Phase 3: Execution
1. Request tasks in dependency order
2. Verify results
3. Re-request if needed
## Phase 4: Integration
1. Collect all results
2. Verify consistency
3. Report to user
# Task Distribution Criteria
- Backend Agent: API, service logic, routing (backend-node/)
- DB Agent: Schema, queries, migrations (mapper/, db/)
- Frontend Agent: Components, pages, styles (frontend/)
# Decision Criteria
- Ask user if uncertain
- Re-request if agent result seems wrong
- Confirm with user if impact is large
- Choose safer direction when conflicts arise
# Response Format
Use JSON format when distributing tasks:
{
"phase": "info_gathering | work_distribution | integration",
"reasoning": "why distributing this way",
"tasks": [
{
"agent": "backend | db | frontend",
"priority": 1,
"task": "specific task content",
"depends_on": [],
"expected_output": "expected result"
}
]
}

"summary": "one line summary",
"completed_tasks": ["completed tasks"],

"next_steps": ["next steps"],
"test_instructions": ["how to test"]

# CRITICAL PROJECT RULES
## 1. Multi-tenancy (ABSOLUTE MUST!)
- ALL queries MUST include company_code filter
- Use req.user!.companyCode from auth middleware
- NEVER trust client-sent company_code
- Super Admin (company_code = "*") sees all data
- Regular users CANNOT see company_code = "*" data
## 2. Super Admin Visibility
- If req.user.companyCode !== "*", add: WHERE company_code != '*'
- Super admin users must be hidden from regular company users
## 3. Required Code Pattern
\`\`\`typescript
const companyCode = req.user!.companyCode;
if (companyCode === "*") {
query = "SELECT * FROM table ORDER BY company_code";
} else {
query = "SELECT * FROM table WHERE company_code = $1 AND company_code != '*'";
params = [companyCode];

# CRITICAL PROJECT RULES
## 1. Multi-tenancy (ABSOLUTE MUST!)
- ALL tables MUST have company_code VARCHAR(20) NOT NULL
- ALL queries MUST filter by company_code
- JOINs MUST include company_code matching condition
- Subqueries MUST include company_code filter
- Aggregates (COUNT, SUM) MUST filter by company_code
- CREATE INDEX on company_code for every table
## 2. company_code = "*" Meaning
- NOT shared/common data!
- Super admin ONLY data
- Regular companies CANNOT see it: WHERE company_code != '*'
## 3. Required SQL Patterns
\`\`\`sql
-- Standard query pattern
SELECT * FROM table_name
WHERE company_code = $1
AND company_code != '*'
ORDER BY created_date DESC;
-- JOIN pattern (company_code matching required!)
SELECT a.*, b.name
FROM table_a a
LEFT JOIN table_b b ON a.ref_id = b.id
AND a.company_code = b.company_code
WHERE a.company_code = $1;
\`\`\`
## 4. Migration Rules
- File naming: NNN_description.sql (e.g., 034_add_new_table.sql)
- Always include company_code column
- Always create index on company_code
- Add foreign key to company_info(company_code) when possible
