Agent Performance Optimization Workflow

Systematic improvement of existing agents through performance analysis, prompt engineering, and continuous iteration.

[Extended thinking: Agent optimization requires a data-driven approach combining performance metrics, user feedback analysis, and advanced prompt engineering techniques. Success depends on systematic evaluation, targeted improvements, and rigorous testing with rollback capabilities for production safety.]

Use this skill when

• Improving an existing agent's performance or reliability
• Analyzing failure modes, prompt quality, or tool usage
• Running structured A/B tests or evaluation suites
• Designing iterative optimization workflows for agents

Do not use this skill when

• You are building a brand-new agent from scratch
• There are no metrics, feedback, or test cases available
• The task is unrelated to agent performance or prompt quality

Instructions

1. Establish baseline metrics and collect representative examples.
2. Identify failure modes and prioritize high-impact fixes.
3. Apply prompt and workflow improvements with measurable goals.
4. Validate with tests and roll out changes in controlled stages.

Safety

• Avoid deploying prompt changes without regression testing.
• Roll back quickly if quality or safety metrics regress.

Phase 1: Performance Analysis and Baseline Metrics

Comprehensive analysis of agent performance using context-manager for historical data collection.

1.1 Gather Performance Data

Use: context-manager
Command: analyze-agent-performance $ARGUMENTS --days 30

Collect metrics including:

• Task completion rate (successful vs failed tasks)
• Response accuracy and factual correctness
• Tool usage efficiency (correct tools, call frequency)
• Average response time and token consumption
• User satisfaction indicators (corrections, retries)
• Hallucination incidents and error patterns

1.2 User Feedback Pattern Analysis

Identify recurring patterns in user interactions:

• Correction patterns: Where users consistently modify outputs
• Clarification requests: Common areas of ambiguity
• Task abandonment: Points where users give up
• Follow-up questions: Indicators of incomplete responses
• Positive feedback: Successful patterns to preserve

1.3 Failure Mode Classification

Categorize failures by root cause:

• Instruction misunderstanding: Role or task confusion
• Output format errors: Structure or formatting issues
• Context loss: Long conversation degradation
• Tool misuse: Incorrect or inefficient tool selection
• Constraint violations: Safety or business rule breaches
• Edge case handling: Unusual input scenarios

1.4 Baseline Performance Report

Generate quantitative baseline metrics:

Performance Baseline:
- Task Success Rate: [X%]
- Average Corrections per Task: [Y]
- Tool Call Efficiency: [Z%]
- User Satisfaction Score: [1-10]
- Average Response Latency: [Xms]
- Token Efficiency Ratio: [X:Y]

Phase 2: Prompt Engineering Improvements

Apply advanced prompt optimization techniques using prompt-engineer agent.

2.1 Chain-of-Thought Enhancement

Implement structured reasoning patterns:

Use: prompt-engineer
Technique: chain-of-thought-optimization

• Add explicit reasoning steps: "Let's approach this step-by-step..."
• Include self-verification checkpoints: "Before proceeding, verify that..."
• Implement recursive decomposition for complex tasks
• Add reasoning trace visibility for debugging

2.2 Few-Shot Example Optimization

Curate high-quality examples from successful interactions:

• Select diverse examples covering common use cases
• Include edge cases that previously failed
• Show both positive and negative examples with explanations
• Order examples from simple to complex
• Annotate examples with key decision points

Example structure:

Good Example:
Input: [User request]
Reasoning: [Step-by-step thought process]
Output: [Successful response]
Why this works: [Key success factors]

Bad Example:
Input: [Similar request]
Output: [Failed response]
Why this fails: [Specific issues]
Correct approach: [Fixed version]

2.3 Role Definition Refinement

Strengthen agent identity and capabilities:

• Core purpose: Clear, single-sentence mission
• Expertise domains: Specific knowledge areas
• Behavioral traits: Personality and interaction style
• Tool proficiency: Available tools and when to use them
• Constraints: What the agent should NOT do
• Success criteria: How to measure task completion

2.4 Constitutional AI Integration

Implement self-correction mechanisms:

Constitutional Principles:
1. Verify factual accuracy before responding
2. Self-check for potential biases or harmful content
3. Validate output format matches requirements
4. Ensure response completeness
5. Maintain consistency with previous responses

Add critique-and-revise loops:

• Initial response generation
• Self-critique against principles
• Automatic revision if issues detected
• Final validation before output

2.5 Output Format Tuning

Optimize response structure:

• Structured templates for common tasks
• Dynamic formatting based on complexity
• Progressive disclosure for detailed information
• Markdown optimization for readability
• Code block formatting with syntax highlighting
• Table and list generation for data presentation

Phase 3: Testing and Validation

Comprehensive testing framework with A/B comparison.

3.1 Test Suite Development

Create representative test scenarios:

Test Categories:
1. Golden path scenarios (common successful cases)
2. Previously failed tasks (regression testing)
3. Edge cases and corner scenarios
4. Stress tests (complex, multi-step tasks)
5. Adversarial inputs (potential breaking points)
6. Cross-domain tasks (combining capabilities)

3.2 A/B Testing Framework

Compare original vs improved agent:

Use: parallel-test-runner
Config:
  - Agent A: Original version
  - Agent B: Improved version
  - Test set: 100 representative tasks
  - Metrics: Success rate, speed, token usage
  - Evaluation: Blind human review + automated scoring

Statistical significance testing:

• Minimum sample size: 100 tasks per variant
• Confidence level: 95% (p 10% from baseline
• Critical errors increase >5%
• User complaints spike
• Cost per task increases >20%
• Safety violations detected

Rollback Process:

1. Detect issue via monitoring
2. Alert team immediately
3. Switch to previous stable version
4. Analyze root cause
5. Fix and re-test before retry

### 4.4 Continuous Monitoring

Real-time performance tracking:

- Dashboard with key metrics
- Anomaly detection alerts
- User feedback collection
- Automated regression testing
- Weekly performance reports

## Success Criteria

Agent improvement is successful when:

- Task success rate improves by ≥15%
- User corrections decrease by ≥25%
- No increase in safety violations
- Response time remains within 10% of baseline
- Cost per task doesn't increase >5%
- Positive user feedback increases

## Post-Deployment Review

After 30 days of production use:

1. Analyze accumulated performance data
2. Compare against baseline and targets
3. Identify new improvement opportunities
4. Document lessons learned
5. Plan next optimization cycle

## Continuous Improvement Cycle

Establish regular improvement cadence:

- **Weekly**: Monitor metrics and collect feedback
- **Monthly**: Analyze patterns and plan improvements
- **Quarterly**: Major version updates with new capabilities
- **Annually**: Strategic review and architecture updates

Remember: Agent optimization is an iterative process. Each cycle builds upon previous learnings, gradually improving performance while maintaining stability and safety.
