Skill Discovery And Chaining
Skill Profile
(Select at least one profile to enable specific modules)
Overview
Skill discovery and chaining is the process of finding appropriate skills for tasks, analyzing compatibility between skills, and chaining skills together to solve complex problems, including handling failures and optimizing sequences.
Why This Matters
- Efficiency: Select most appropriate skills for each task
- Flexibility: Chain skills in multiple ways without limiting patterns
- Reliability: Handle skill failures gracefully with fallback mechanisms
- Optimization: Reduce redundant skill calls and improve performance
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:
- Task descriptions and requirements
- Skill registry with available skills
- Chain definitions
- Fallback skill definitions
- Entry Conditions:
- Skill registry is initialized
- Embedding service is available
- Fallback skills are defined
- Outputs:
- Matched skills with relevance scores
- Executed skill chains with results
- Optimization recommendations
- Failure reports
- Artifacts Required (Deliverables):
- Skill registry implementation
- Skill matcher with semantic similarity
- Skill chainer with execution logic
- Failure handler with retry logic
- Sequence optimizer
- Acceptance Evidence:
- Skills are discovered and indexed
- Matches are scored by relevance
- Chains execute successfully
- Fallback mechanisms work correctly
- Success Criteria:
- 100% of tasks find matching skills
- 100% of chains execute without errors
- Fallback success rate > 80%
- Sequence optimization reduces redundant calls by > 30%
Skill Composition
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

Technical Guardrails & Security Threat Model
1. Security & Privacy (Threat Model)
- Top Threats: Injection attacks, authentication bypass, data exposure
2. Performance & Resources
3. Architecture & Scalability
4. Observability & Reliability
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
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
Reference Links & Examples
