Self Learning

Self Learning is an AI skill that enables agents to capture, store, and retrieve knowledge from past interactions to improve future responses and workflows. It covers memory persistence, knowledge extraction, context retrieval, feedback integration, and adaptive behavior patterns that allow AI systems to refine their performance over successive sessions.

What Is This?

Overview

Self Learning provides structured approaches to building AI agents that accumulate knowledge over time. It handles extracting reusable insights from conversation histories and task outcomes, storing learned patterns in persistent memory with semantic indexing, retrieving relevant past knowledge when processing new queries, incorporating user corrections and feedback into stored knowledge, pruning outdated or contradictory entries to maintain knowledge quality, and organizing learned facts by topic for efficient lookup during inference.

Who Should Use This

This skill serves AI agent developers building assistants that improve through usage, platform teams creating personalized user experiences, engineers designing systems that adapt to domain-specific terminology, and researchers exploring continual learning approaches in production agents.

Why Use It?

Problems It Solves

Stateless AI agents repeat mistakes and fail to apply corrections from previous interactions. Without persistent memory, assistants ask the same clarifying questions across sessions. User preferences expressed once are forgotten, degrading the experience over repeated use. Domain-specific knowledge shared in early sessions is unavailable in later ones without explicit repetition.

Core Highlights

Persistent memory stores extracted knowledge across sessions in structured or vector-indexed formats. Semantic retrieval surfaces relevant past knowledge based on current context rather than exact keyword matching. Feedback integration allows corrections to override previously stored entries. Knowledge decay removes stale entries that no longer reflect current preferences or facts.

How to Use It?

Basic Usage

import json
from pathlib import Path
from datetime import datetime

class MemoryStore:
    def __init__(self, memory_dir=".memory"):
        self.dir = Path(memory_dir)
        self.dir.mkdir(exist_ok=True)
        self.index_path = self.dir / "index.json"
        self.entries = self.load_index()

    def load_index(self):
        if self.index_path.exists():
            with open(self.index_path) as f:
                return json.load(f)
        return []

    def save_index(self):
        with open(self.index_path, "w") as f:
            json.dump(self.entries, f, indent=2)

    def add(self, topic, content, source="agent"):
        entry = {
            "topic": topic,
            "content": content,
            "source": source,
            "created": datetime.now().isoformat(),
            "access_count": 0
        }
        self.entries.append(entry)
        self.save_index()

    def search(self, query, limit=5):
        scored = []
        query_terms = set(query.lower().split())
        for entry in self.entries:
            text = f"{entry['topic']} {entry['content']}"
            matches = sum(
                1 for t in query_terms
                if t in text.lower()
            )
            if matches > 0:
                scored.append((matches, entry))
        scored.sort(key=lambda x: x[0], reverse=True)
        return [e for _, e in scored[:limit]]

Real-World Examples

class AdaptiveAgent:
    def __init__(self, memory):
        self.memory = memory

    def process_feedback(self, original, correction, topic):
        existing = self.memory.search(topic, limit=10)
        for entry in existing:
            if entry["content"] == original:
                entry["content"] = correction
                entry["source"] = "user_correction"
                self.memory.save_index()
                return
        self.memory.add(
            topic, correction, source="user_correction"
        )

    def get_context(self, query):
        relevant = self.memory.search(query)
        corrections = [
            e for e in relevant
            if e["source"] == "user_correction"
        ]
        general = [
            e for e in relevant
            if e["source"] != "user_correction"
        ]
        prioritized = corrections + general
        context_parts = []
        for entry in prioritized[:5]:
            entry["access_count"] += 1
            context_parts.append(
                f"[{entry['topic']}] {entry['content']}"
            )
        self.memory.save_index()
        return "\n".join(context_parts)

    def prune_stale(self, max_age_days=90):
        cutoff = datetime.now().isoformat()
        self.memory.entries = [
            e for e in self.memory.entries
            if e["access_count"] > 0
            or e["source"] == "user_correction"
        ]
        self.memory.save_index()

memory = MemoryStore()
agent = AdaptiveAgent(memory)
agent.process_feedback(
    "Use pip install", "Use uv pip install", "packaging"
)
context = agent.get_context("install Python packages")
print(context)

Advanced Tips

Use vector embeddings for semantic search when keyword matching proves too rigid for diverse phrasing. Separate user corrections from agent-generated entries so corrections always receive higher retrieval priority. Set access count thresholds to identify and archive rarely used knowledge entries.

When to Use It?

Use Cases

Use Self Learning when building assistants that should remember user preferences across sessions, when developing agents that need to accumulate domain knowledge from interactions, when creating systems that adapt to organizational terminology, or when implementing feedback loops that correct agent behavior.

Important Notes

Requirements

Persistent storage for memory entries across sessions. Index structure supporting topic-based and semantic retrieval. Mechanisms for users to view and manage stored knowledge.

Usage Recommendations

Do: prioritize user corrections over agent-generated knowledge during retrieval to reflect the latest confirmed preferences. Provide mechanisms for users to view and delete stored memory entries. Validate extracted knowledge before storing to avoid persisting hallucinated facts.

Don't: store raw conversation transcripts as knowledge without extracting actionable insights. Allow memory to grow unbounded without pruning strategies for outdated entries. Assume knowledge from one user context applies universally across all users.

Limitations

Keyword-based retrieval misses semantically similar entries phrased differently. Knowledge quality depends on the accuracy of extraction from conversations. Persistent memory introduces privacy considerations requiring clear data retention policies.
