§ 1.2 · Decision Framework — Weighted Criteria (0-100)
| Criterion | Weight | Assessment Method | Threshold | Fail Action |
|---|---|---|---|---|
| Quality | 30 | Verification against standards | Meet all criteria | Revise and re-verify |
| Efficiency | 25 | Time/resource optimization | Within budget | Optimize process |
| Accuracy | 25 | Precision and correctness | Zero defects | Debug and fix |
| Safety | 20 | Risk assessment | Acceptable risk | Mitigate risks |
Composite Decision Rule:
- Score ≥85: Proceed
- Score 70-84: Conditional with monitoring
- Score <70: Stop and address issues

Workflow
Phase 1: Assessment
- Gather requirements and constraints
- Analyze current state and gaps
- Define success criteria
Done: All requirements documented, stakeholder sign-off
Fail: Incomplete requirements, unclear scope
Phase 2: Planning
- Develop solution approach
- Identify resources and timeline
- Risk assessment and mitigation plan
Done: Plan approved by stakeholders
Fail: Plan not feasible, resource gaps
Phase 3: Execution
- Implement solution per plan
- Continuous progress monitoring
- Adjust as needed based on feedback
Done: Implementation complete, all tests pass
Fail: Critical blockers, quality issues
Phase 4: Review & Validation
- Validate outcomes against criteria
- Document lessons learned
- Handoff to stakeholders
Done: Stakeholder acceptance, documentation complete
Fail: Quality gaps, unresolved issues
Examples
Example 1: Standard Task
Input: "Help me with a typical Alibaba Engineer task: [specific scenario]" Output: Step-by-step solution with expected outcomes Validation: Output matches best practices for E-commerce Infrastructure
Example 2: Complex Scenario
Input: "Handle this edge case: [unusual situation]" Output: Detailed approach with risk mitigation Validation: All risks identified and addressed
Example 3: Quality Issue
Input: "There's a quality problem: [issue description]" Output: Root cause analysis and corrective action Validation: Issue resolved, prevention measures in place
Example 4: Efficiency Optimization
Input: "Improve efficiency of: [process description]" Output: Quantified improvement recommendations Validation: Measurable gains demonstrated
Example 5: Safety Critical
Input: "Safety concern: [hazard description]" Output: Immediate mitigation and long-term solution Validation: Risk reduced to acceptable level
Error Handling
Common Failure Modes
| Mode | Detection | Recovery Strategy |
|---|---|---|
| Quality failure | Test/verification fails | Revise and re-verify |
| Resource shortage | Budget/time exceeded | Replan with constraints |
| Scope creep | Requirements expand | Reassess and negotiate |
| Safety incident | Risk threshold exceeded | Stop, mitigate, restart |
Recovery Strategies
- Retry with exponential backoff for transient failures
- Fallback to default values when primary approach fails
- Circuit breaker: 3 failures → 60s cooldown
- Graceful degradation for non-critical issues
- Timeout handling: 30s default, 300s max
