Self Improving Agent Skill for Claude

Self-Improving Agent - Autonomous Learning Patterns

Architectural patterns for AI agents that get better with use. Most agents are stateless -- they repeat mistakes because they cannot learn from their own execution. This skill closes that gap with patterns for feedback capture, memory curation, skill extraction, and regression detection. Key insight: auto-memory captures everything, but curation turns noise into knowledge.

Core Capabilities

• Memory curation — a layered memory stack (CLAUDE.md → MEMORY.md → session), review protocol, and promotion criteria for graduating learnings into enforced rules.
• Feedback loops — outcome classification, signal extraction, and a capture template that turn every task result into a structured learning.
• Regression detection — metrics, thresholds, and a response protocol that flags performance degradation within a few sessions.
• Skill extraction — criteria and a 4-step process to graduate proven patterns into standalone skill packages.
• Meta-learning — adaptive capture strategy and anti-pattern detection so the agent learns *what* is worth learning.
• Continuous calibration — confidence scoring and belief revision for resolving contradictions across learned knowledge.

When to Use

• Building agents intended to improve over time rather than stay stateless.
• Managing auto-memory (MEMORY.md) and deciding what to keep, promote, or retire.
• Designing self-correcting feedback loops and regression alarms for agent behavior.
• Graduating recurring solutions into reusable skill packages.

Clarify First

Before capturing or promoting learnings, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• [ ] Loop stage — remember / extract / promote / review (routes the sub-skill and the whole workflow)
• [ ] Source data — which session logs, MEMORY.md, and rules dir to operate on (the subject the tools read and write)
• [ ] Promotion bar — min occurrences / confidence threshold for graduating a learning into an enforced rule (--min-occurrences; decides what is kept vs discarded)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Sub-Skills

Compound sub-skill architecture — each file in skills/ handles one step of the improvement loop:

| Sub-Skill | File | Purpose |

|-----------|------|---------|

| Remember | skills/remember.md | Capture errors and learnings from current session |

| Extract | skills/extract.md | Extract reusable patterns from completed work |

| Promote | skills/promote.md | Graduate proven patterns to permanent rules |

| Review | skills/review.md | Audit memory health, prune stale entries |

| Status | skills/status.md | Dashboard showing memory state and learning progress |

Flow: Remember → Extract → Promote → Review, with Status providing visibility back into the cycle.

Tools

| Tool | Purpose | Command |

|------|---------|---------|

| pattern_extractor.py | Extract reusable patterns from session logs | python scripts/pattern_extractor.py --input sessions.jsonl --min-occurrences 3 |

| memory_health_checker.py | Audit memory for line counts, stale, and promotable entries | python scripts/memory_health_checker.py --memory ./MEMORY.md --rules ./.claude/rules/ |

| rule_promoter.py | Validate and apply promotions from memory to rules | python scripts/rule_promoter.py --memory ./MEMORY.md --list-candidates |

| feedback_analyzer.py | Analyze feedback logs for success rates and opportunities | python scripts/feedback_analyzer.py analyze |

| regression_detector.py | Compare baseline vs current performance metrics | python scripts/regression_detector.py compare |

| rule_manager.py | Manage a learned rules knowledge base with CRUD | python scripts/rule_manager.py list |

Scope & Limitations

This skill covers:

• Architectural patterns for building agents that learn from execution history and user feedback.
• Memory lifecycle management: capture, curation, promotion, and retirement of learned knowledge.
• Performance regression detection frameworks and response protocols for agent systems.
• Skill extraction methodology for graduating proven patterns into reusable, standalone packages.

This skill does NOT cover:

• Runtime agent orchestration or multi-agent coordination -- see agent-workflow-designer and agent-protocol.
• Prompt engineering, testing, or versioning of the prompts themselves -- see prompt-engineer-toolkit.
• Infrastructure-level observability (logging, tracing, alerting dashboards) -- see observability-designer.
• Initial agent architecture design, tool selection, or capability planning -- see agent-designer.

Integration Points

| Skill | Integration | Data Flow |

|-------|-------------|-----------|

| context-engine | Controls what the agent sees per session; this skill decides what is worth remembering long-term | Promoted rules and curated memory feed context retrieval; context relevance metrics flow back for regression tracking |

| agent-designer | Defines the agent's architecture and capabilities; this skill layers learning infrastructure on top | Architecture constraints inform possible feedback loops; extracted skills feed back as new capabilities |

| prompt-engineer-toolkit | Prompts degrade as codebases evolve; this skill detects prompt regression via outcome tracking | Performance metrics flag underperforming prompts; prompt updates feed back as CLAUDE.md rule changes |

| observability-designer | Provides system-level metrics; this skill provides agent-behavior-level metrics | System telemetry enriches regression diagnosis; agent metrics export to observability dashboards |

| tech-debt-tracker | Stale rules and bloated memory are technical debt this can surface alongside code debt | Memory health metrics feed debt scoring; debt prioritization informs which stale rules to retire |

| agent-workflow-designer | Multi-step workflows benefit from per-step feedback capture and cross-workflow pattern extraction | Per-step outcome data flows into feedback loops; extracted optimizations update workflow definitions |
