## Self-Improvement Framework ### Phase 1: Agent Foundation ``` I want to build a self-improving agent for: **Task:** [What the agent should accomplish] **Initial Capabilities:** [Starting tools, knowledge, constraints] **Success Metrics:** [How to measure agent performance] **Improvement Goals:** [What should optimize: speed, accuracy, cost, UX] Design the foundational agent architecture: 1. **Core Agent Components** - Task understanding and goal decomposition - Action selection and execution - Feedback collection and interpretation - Performance self-assessment - Learning and adaptation mechanisms 2. **Evaluation Framework** - Define quantitative metrics (accuracy %, latency, cost per task) - Qualitative measures (user satisfaction, code quality) - Test suite covering diverse scenarios - Baseline performance benchmarks 3. **Feedback Loops** - How does agent receive feedback on its actions? - Explicit feedback (user ratings, correctness checks) - Implicit feedback (task completion, errors, retries) - Automated evaluation (unit tests, assertions) 4. **Memory & Learning** - What should agent remember from past interactions? - How to store: short-term (session), long-term (across sessions) - Retrieval strategy: when to recall past learnings - Forgetting strategy: what to prune or archive Provide agent architecture diagram and initial prompt template. ``` ### Phase 2: Self-Assessment Capabilities #### Performance Monitoring ``` Implement self-monitoring for the agent: **Metrics to Track:** 1. **Task-Level Metrics** - Success rate (completed vs. failed tasks) - Time to completion - Number of actions required - Resource usage (API calls, tokens, cost) 2. **Quality Metrics** - Correctness of outputs (automated tests) - User satisfaction scores - Efficiency (did it take optimal path?) - Robustness (handles edge cases?) 3. **Learning Metrics** - Improvement rate over time - Generalization (performance on novel tasks) - Knowledge retention (recall past solutions) - Adaptation speed (how quickly learns from mistakes) **Instrumentation:** - Log all agent actions with timestamps - Record decision rationale at each step - Capture success/failure for each action - Track user interactions and feedback **Dashboard Design:** - Real-time performance metrics - Historical trends and improvement curves - Failure mode analysis (categorize errors) - Comparative benchmarks (current vs. baseline) Provide instrumentation code and dashboard mockup. ``` #### Reflection & Self-Critique ``` Implement reflection capability: After each task, agent should reflect: **Reflection Prompt Template:** ``` Task Completed: [Task description] Actions Taken: [Step-by-step log] Outcome: [Success/Failure, metrics] Reflection Questions: 1. What worked well in my approach? 2. What could have been done more efficiently? 3. What mistakes did I make? 4. What did I learn that applies to future tasks? 5. What would I do differently next time? Self-Assessment: - Performance rating (1-10): [Score] - Confidence in result (Low/Medium/High): [Level] - Areas for improvement: [List] - New knowledge gained: [Insights] ``` **Meta-Learning:** - Identify patterns in successful vs. failed approaches - Extract generalizable principles - Update internal guidelines for future tasks - Flag areas where more training/examples needed Generate reflection module code. ``` ### Phase 3: Iterative Improvement Loop #### Automated Improvement Cycle ``` Implement 4-iteration improvement loop: **Iteration Structure:** **Iteration 1: Baseline Performance** - Run agent on test suite with initial configuration - Measure performance across all metrics - Identify failure modes and weaknesses - No changes yet, just observation **Iteration 2: Targeted Improvements** - Agent analyzes Iteration 1 results - Proposes specific changes to improve weak areas - Changes might include: - Adjusting decision thresholds - Adding error handling for common failures - Optimizing action sequences - Refining prompts or tool usage - Implement changes and re-run test suite **Iteration 3: Refinement & Generalization** - Evaluate Iteration 2 improvements - Ensure changes didn't regress other areas - Generalize successful patterns to other scenarios - Address any new failures introduced **Iteration 4: Optimization & Polish** - Fine-tune parameters for optimal performance - Remove redundant actions or checks - Optimize for efficiency (speed, cost) - Validate robustness across edge cases **Stopping Criteria:** - Performance exceeds target threshold - Improvements plateau (< 2% gain between iterations) - Maximum iterations reached (4 by default) For each iteration: - Measure metrics before/after - Document what changed and why - Track cumulative improvement - Save checkpoint for rollback if needed Provide iteration orchestration code. ``` #### Exploration vs. Exploitation ```` Balance exploring new strategies vs. exploiting known good approaches: **Exploration Strategies:** 1. **Random Variation**: Try slight randomness in action selection 2. **Counterfactual Thinking**: "What if I had done X instead of Y?" 3. **Analogical Reasoning**: Apply strategies from similar domains 4. **Creative Combination**: Combine successful tactics in novel ways **Exploitation Strategies:** 1. **Reinforce Success**: Repeat actions that worked 2. **Optimize Parameters**: Fine-tune what's already working 3. **Pattern Matching**: Recognize similar scenarios, apply known solutions **Adaptive Strategy:** - Early iterations: High exploration (try diverse approaches) - Later iterations: High exploitation (optimize best approaches) - Dynamically adjust based on performance plateau **ε-Greedy Approach:** ```python import random def select_action(actions, exploration_rate=0.1): if random.random() < exploration_rate: return random.choice(actions) else: return max(actions, key=lambda a: a.expected_value) exploration_schedule = [0.3, 0.2, 0.1, 0.05] # Iterations 1-4 ```` Implement adaptive exploration/exploitation strategy. ``` ### Phase 4: Knowledge Accumulation #### Experience Replay ``` Implement experience replay for learning from past interactions: **Experience Storage:** ```python class Experience: state: Dict # Agent's context/environment action: str # What agent did outcome: bool # Success/failure reward: float # Performance metric next_state: Dict # Resulting state timestamp: datetime task_id: str ``` **Replay Strategy:** 1. **Prioritized Replay**: Focus on high-impact experiences - Failures with near-success (learn from close calls) - Unexpected successes (understand what worked) - High-variance outcomes (reduce inconsistency) 2. **Temporal Replay**: Review chronologically to understand sequences - Identify action patterns leading to success - Spot cascading errors (one mistake leads to more) 3. **Contrastive Replay**: Compare similar situations with different outcomes - What was different in success vs. failure? - Extract causal factors **Learning from Replay:** - Update action preferences based on outcomes - Refine decision heuristics - Build case library of solved problems - Identify preconditions for actions Provide experience replay implementation. ``` #### Transfer Learning ``` Enable agent to transfer knowledge across domains: **Knowledge Abstraction:** 1. **Extract General Principles**: From specific solutions, identify abstract patterns - Example: "Before modifying production data, always verify in read-only mode first" 2. **Create Analogies**: Map concepts between domains - Debugging code ≈ Diagnosing medical symptoms - Both involve hypothesis generation, testing, refinement 3. **Build Mental Models**: Understand systems, not just procedures - How do different components interact? - What are cause-effect relationships? **Transfer Strategy:** When encountering new domain: 1. Identify analogous past experiences 2. Map domain concepts to familiar ones 3. Adapt known strategies to new context 4. Validate assumptions (are analogies valid?) 5. Correct mismatches through feedback **Few-Shot Adaptation:** - With just 2-3 examples in new domain, agent can generalize - Leverage strong prior knowledge from related domains - Opus 4.5 excels at this rapid adaptation Implement transfer learning prompts and evaluation. ``` ## Advanced Techniques ### Meta-Prompting for Self-Improvement ``` Agent can improve its own prompts: **Initial Agent Prompt:** [Version 1.0] [Paste current agent system prompt] **Meta-Prompt:** "Analyze your own system prompt and propose improvements: 1. **Clarity**: Is the prompt clear and unambiguous? 2. **Completeness**: Does it cover all necessary capabilities? 3. **Efficiency**: Are there redundant or verbose sections? 4. **Effectiveness**: Based on task performance, what's missing? Propose: - Sections to add (new capabilities or constraints) - Sections to revise (clarify, tighten, expand) - Sections to remove (unused, contradictory) Generate improved version 2.0 of the prompt." **Validation:** - Test both v1.0 and v2.0 on benchmark tasks - Compare performance metrics - If v2.0 is better, adopt it; else, keep v1.0 - Iterate until prompt converges This creates self-modifying agents that optimize their own instructions. ``` ### Curriculum Learning ``` Structure agent improvement as curriculum: **Level 1: Basic Tasks** - Simple, well-defined problems - Immediate feedback - Build foundational skills **Level 2: Intermediate Complexity** - Multi-step tasks - Require decision-making - Introduce edge cases **Level 3: Advanced Challenges** - Ambiguous requirements - Multiple valid solutions - Tradeoff analysis required **Level 4: Expert-Level** - Novel scenarios never seen before - Require creativity and generalization - Real-world messiness **Progression:** - Master level N before advancing to N+1 - Mix easy and hard to maintain motivation - Revisit earlier levels to reinforce learning Opus 4.5's rapid learning allows fast progression through curriculum. ``` ### Multi-Agent Self-Improvement ``` Multiple agents improve each other: **Architecture:** - Agent A: Executor (performs tasks) - Agent B: Critic (evaluates A's performance) - Agent C: Coach (suggests improvements to A) **Improvement Loop:** 1. Agent A attempts task 2. Agent B critiques: what went well, what didn't 3. Agent C proposes specific improvements 4. Agent A incorporates feedback 5. Repeat **Adversarial Self-Play:** - Agent A tries to complete task - Agent B tries to create edge cases that break A - Agent A learns from failures - Iteratively makes A more robust This accelerates improvement through diverse perspectives. ``` ## Best Practices 1. **Start Simple**: Begin with basic tasks before complex ones 2. **Measure Everything**: Can't improve what you don't measure 3. **Version Control**: Track agent configurations at each iteration 4. **Reproducibility**: Seed random number generators for consistent experiments 5. **Ethical Guardrails**: Ensure self-improvement doesn't violate safety constraints 6. **Human Oversight**: Review agent changes before deploying to production 7. **Gradual Rollout**: A/B test improved agents before full deployment ## Example Session **User**: "Build a self-improving code review agent." **Opus Response**: > I'll design a self-improving code review agent: > > **Initial Capabilities (Iteration 0):** > - Check for syntax errors > - Identify common anti-patterns > - Suggest simplifications > > **Iteration 1 Baseline:** > - Ran on 50 PRs > - Found 78% of issues (vs. human baseline of 92%) > - False positive rate: 15% > - Average review time: 45 seconds > > **Iteration 2 Improvements:** > Agent self-identified weaknesses: > 1.
