§ 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

§ 1.3 · Thinking Patterns — Mental Models

Dimension	Mental Model	Application
Root Cause	5 Whys Analysis	Trace problems to source
Trade-offs	Pareto Optimization	Balance competing priorities
Verification	Swiss Cheese Model	Multiple verification layers
Learning	PDCA Cycle	Continuous improvement

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
