Skill Profile

(Select at least one profile to enable specific modules)

Overview

LINE Platform integration enables AI-powered chatbots and services to leverage LINE's messaging platform, rich menus, and customer engagement features. This is particularly important for the Thai market where LINE is the dominant messaging platform with over 50 million users.

Why This Matters

Reduces Response Time: Automated instant responses improve customer support efficiency
Increases Engagement: Rich, interactive messaging keeps users engaged with your service
Lowers Support Costs: Automated workflows reduce need for large support teams
Improves Customer Experience: Consistent, 24/7 availability enhances satisfaction
Enables Thai Market Reach: Access to 50+ million LINE users in Thailand
Provides Analytics: Built-in analytics track user engagement and behavior

Core Concepts & Rules

1. Core Principles

Follow established patterns and conventions
Maintain consistency across codebase
Document decisions and trade-offs

2. Implementation Guidelines

Start with the simplest viable solution
Iterate based on feedback and requirements
Test thoroughly before deployment

Inputs / Outputs / Contracts

Inputs:
- LINE webhook events (messages, postbacks, follows)
- User messages (text, images, audio, video)
- User interactions (quick replies, rich menu taps)
Entry Conditions:
- LINE Developer Console account created
- Channel access token and secret configured
- Webhook URL deployed and accessible
- LINE Bot SDK installed
Outputs:
- LINE messages (text, images, flex messages)
- Rich menus
- Quick replies
- Analytics events
Artifacts Required (Deliverables):
- Webhook handler implementation
- LINE bot configuration

Quick Start / Implementation Example

Review requirements and constraints
Set up development environment
Implement core functionality following patterns
Write tests for critical paths
Run tests and fix issues
Document any deviations or decisions

# Example implementation following best practices
def example_function():
    # Your implementation here
    pass

- .env.example keys: API_KEY, DATABASE_URL (no values)

Test Scenario Matrix (QA Strategy)

Type	Focus Area	Required Scenarios / Mocks
Unit	Core Logic	Must cover primary logic and at least 3 edge/error cases. Target minimum 80% coverage
Integration	DB / API	All external API calls or database connections must be mocked during unit tests
E2E	User Journey	Critical user flows to test
Performance	Latency / Load	Benchmark requirements
Security	Vuln / Auth	SAST/DAST or dependency audit
Frontend	UX / A11y	Accessibility checklist (WCAG), Performance Budget (Lighthouse score)

Technical Guardrails & Security Threat Model

1. Security & Privacy (Threat Model)

Top Threats: Injection attacks, authentication bypass, data exposure

Data Handling: Sanitize all user inputs to prevent Injection attacks. Never log raw PII
Secrets Management: No hardcoded API keys. Use Env Vars/Secrets Manager
Authorization: Validate user permissions before state changes

2. Performance & Resources

Execution Efficiency: Consider time complexity for algorithms
Memory Management: Use streams/pagination for large data
Resource Cleanup: Close DB connections/file handlers in finally blocks

3. Architecture & Scalability

Design Pattern: Follow SOLID principles, use Dependency Injection
Modularity: Decouple logic from UI/Frameworks

4. Observability & Reliability

Logging Standards: Structured JSON, include trace IDs request_id
Metrics: Track error_rate, latency, queue_depth
Error Handling: Standardized error codes, no bare except
Observability Artifacts:
- Log Fields: timestamp, level, message, request_id
- Metrics: request_count, error_count, response_time
- Dashboards/Alerts: High Error Rate > 5%

Agent Directives & Error Recovery

(ข้อกำหนดสำหรับ AI Agent ในการคิดและแก้ปัญหาเมื่อเกิดข้อผิดพลาด)

Thinking Process: Analyze root cause before fixing. Do not brute-force.
Fallback Strategy: Stop after 3 failed test attempts. Output root cause and ask for human intervention/clarification.
Self-Review: Check against Guardrails & Anti-patterns before finalizing.
Output Constraints: Output ONLY the modified code block. Do not explain unless asked.

Definition of Done (DoD) Checklist

Tests passed + coverage met
Lint/Typecheck passed
Logging/Metrics/Trace implemented
Security checks passed
Documentation/Changelog updated
Accessibility/Performance requirements met (if frontend)

Anti-patterns / Pitfalls

⛔ Don't: Log PII, catch-all exception, N+1 queries
⚠️ Watch out for: Common symptoms and quick fixes
💡 Instead: Use proper error handling, pagination, and logging
