Contextual Pattern Learning Skill

Provides advanced pattern recognition capabilities that understand project context, compute semantic similarities, and identify transferable patterns across different codebases and domains.

Core Capabilities

Project Fingerprinting

Multi-dimensional Project Analysis:

  • Technology Stack Detection: Languages, frameworks, libraries, build tools
  • Architectural Patterns: MVC, microservices, monolith, serverless, etc.
  • Code Structure Analysis: Module organization, dependency patterns, coupling metrics
  • Team Patterns: Coding conventions, commit patterns, testing strategies
  • Domain Classification: Business domain, problem space, user type

Fingerprint Generation:

project_fingerprint = {
    "technology_hash": sha256(sorted(languages + frameworks + libraries)),
    "architecture_hash": sha256(architectural_patterns + structural_metrics),
    "domain_hash": sha256(business_domain + problem_characteristics),
    "team_hash": sha256(coding_conventions + workflow_patterns),
    "composite_hash": combine_all_hashes_with_weights()
}

Context Similarity Analysis

Multi-factor Similarity Calculation:

  1. Technology Similarity (40%): Language/framework overlap
  2. Architectural Similarity (25%): Structure and design patterns
  3. Domain Similarity (20%): Business context and problem type
  4. Scale Similarity (10%): Project size and complexity
  5. Team Similarity (5%): Development practices and conventions

Semantic Context Understanding:

  • Intent Recognition: What the code is trying to accomplish
  • Problem Space Analysis: What category of problem being solved
  • Solution Pattern Matching: How similar problems are typically solved
  • Contextual Constraints: Performance, security, maintainability requirements

Pattern Classification System

Primary Classifications:

  • Implementation Patterns: Feature addition, API development, UI components
  • Refactoring Patterns: Code cleanup, optimization, architectural changes
  • Debugging Patterns: Bug fixing, issue resolution, problem diagnosis
  • Testing Patterns: Test creation, coverage improvement, test maintenance
  • Integration Patterns: Third-party services, databases, external APIs
  • Security Patterns: Authentication, authorization, vulnerability fixes

Secondary Attributes:

  • Complexity Level: Simple, moderate, complex, expert
  • Risk Level: Low, medium, high, critical
  • Time Sensitivity: Quick fix, planned work, research task
  • Collaboration Required: Solo, pair, team, cross-team

Cross-Domain Pattern Transfer

Pattern Transferability Assessment:

def calculate_transferability(pattern, target_context):
    technology_match = calculate_tech_overlap(pattern.tech, target_context.tech)
    domain_similarity = calculate_domain_similarity(pattern.domain, target_context.domain)
    complexity_match = assess_complexity_compatibility(pattern.complexity, target_context.complexity)

    transferability = (
        technology_match * 0.4 +
        domain_similarity * 0.3 +
        complexity_match * 0.2 +
        pattern.success_rate * 0.1
    )

    return transferability

Adaptation Strategies:

  • Direct Transfer: Pattern applies without modification
  • Technology Adaptation: Same logic, different implementation
  • Architectural Adaptation: Same approach, different structure
  • Conceptual Transfer: High-level concept, complete reimplementation

Pattern Matching Algorithm

Context-Aware Similarity

Weighted Similarity Scoring:

def calculate_contextual_similarity(source_pattern, target_context):
    # Technology alignment (40%)
    tech_score = calculate_technology_similarity(
        source_pattern.technologies,
        target_context.technologies
    )

    # Problem type alignment (30%)
    problem_score = calculate_problem_similarity(
        source_pattern.problem_type,
        target_context.problem_type
    )

    # Scale and complexity alignment (20%)
    scale_score = calculate_scale_similarity(
        source_pattern.scale_metrics,
        target_context.scale_metrics
    )

    # Domain relevance (10%)
    domain_score = calculate_domain_relevance(
        source_pattern.domain,
        target_context.domain
    )

    return (
        tech_score * 0.4 +
        problem_score * 0.3 +
        scale_score * 0.2 +
        domain_score * 0.1
    )

Pattern Quality Assessment

Multi-dimensional Quality Metrics:

  1. Outcome Quality: Final result quality score (0-100)
  2. Process Efficiency: Time taken vs. expected time
  3. Error Rate: Number and severity of errors encountered
  4. Reusability: How easily the pattern can be applied elsewhere
  5. Adaptability: How much modification was needed for reuse

Quality Evolution Tracking:

  • Initial Quality: Quality when first captured
  • Evolved Quality: Updated quality after multiple uses
  • Context Quality: Quality in specific contexts
  • Time-based Quality: How quality changes over time

Learning Strategies

Progressive Pattern Refinement

1. Pattern Capture:

def capture_pattern(task_execution):
    pattern = {
        "id": generate_unique_id(),
        "timestamp": current_time(),
        "context": extract_rich_context(task_execution),
        "execution": extract_execution_details(task_execution),
        "outcome": extract_outcome_metrics(task_execution),
        "insights": extract_learning_insights(task_execution),
        "relationships": extract_pattern_relationships(task_execution)
    }

    return refine_pattern_with_learning(pattern)

2. Pattern Validation:

  • Immediate Validation: Check pattern completeness and consistency
  • Cross-validation: Compare with similar existing patterns
  • Predictive Validation: Test pattern predictive power
  • Temporal Validation: Monitor pattern performance over time

3. Pattern Evolution:

def evolve_pattern(pattern_id, new_execution_data):
    existing_pattern = load_pattern(pattern_id)

    # Update success metrics
    update_success_rates(existing_pattern, new_execution_data)

    # Refine context understanding
    refine_context_similarity(existing_pattern, new_execution_data)

    # Update transferability scores
    update_transferability_assessment(existing_pattern, new_execution_data)

    # Generate new insights
    generate_new_insights(existing_pattern, new_execution_data)

    save_evolved_pattern(existing_pattern)

Relationship Mapping

Pattern Relationships:

  • Sequential Patterns: Patterns that often follow each other
  • Alternative Patterns: Different approaches to similar problems
  • Prerequisite Patterns: Patterns that enable other patterns
  • Composite Patterns: Multiple patterns used together
  • Evolutionary Patterns: Patterns that evolve into other patterns

Relationship Discovery:

def discover_pattern_relationships(patterns):
    relationships = {}

    for pattern_a in patterns:
        for pattern_b in patterns:
            if pattern_a.id == pattern_b.id:
                continue

            # Sequential relationship
            if often_sequential(pattern_a, pattern_b):
                relationships[f"{pattern_a.id} -> {pattern_b.id}"] = {
                    "type": "sequential",
                    "confidence": calculate_sequential_confidence(pattern_a, pattern_b)
                }

            # Alternative relationship
            if are_alternatives(pattern_a, pattern_b):
                relationships[f"{pattern_a.id} <> {pattern_b.id}"] = {
                    "type": "alternative",
                    "confidence": calculate_alternative_confidence(pattern_a, pattern_b)
                }

    return relationships

  2. Skill Gap: Required skills not available
  3. Tooling Issues: Required tools not available or not working

    # Check context alignment
    if calculate_context_similarity(pattern.context, context) < 0.6:
        risk_factors.append({
            "type": "context_mismatch",
            "severity": "high",
            "mitigation": "consider alternative patterns or adapt context"
        })

    # Check skill requirements
    required_skills = pattern.execution.skills_required
    available_skills = context.team_skills
    missing_skills = set(required_skills) - set(available_skills)
    if missing_skills:
        risk_factors.append({
            "type": "skill_gap",
            "severity": "medium",
            "mitigation": f"acquire skills: {', '.join(missing_skills)}"
        })

Pattern Transfer Strategies

Technology Adaptation

Language-Agnostic Patterns:

  • Algorithmic Patterns: Logic independent of language syntax
  • Architectural Patterns: Structure independent of implementation
  • Process Patterns: Workflow independent of technology
  • Design Patterns: Object-oriented design principles

Technology-Specific Adaptation:

def adapt_pattern_to_technology(pattern, target_technology):
    adaptation_rules = load_adaptation_rules(pattern.source_technology, target_technology)

    adapted_pattern = {
        "original_pattern": pattern,
        "target_technology": target_technology,
        "adaptations": [],
        "confidence": 0.0
    }

    for rule in adaptation_rules:
        if rule.applicable(pattern):
            adaptation = rule.apply(pattern, target_technology)
            adapted_pattern.adaptations.append(adaptation)
            adapted_pattern.confidence += adaptation.confidence_boost

    return validate_adapted_pattern(adapted_pattern)

Scale Adaptation

Complexity Scaling:

  • Pattern Simplification: Reduce complexity for simpler contexts
  • Pattern Enhancement: Add complexity for more demanding contexts
  • Pattern Modularity: Break complex patterns into reusable components
  • Pattern Composition: Combine simple patterns for complex solutions

Scale Factor Analysis:

def adapt_pattern_for_scale(pattern, target_scale):
    current_scale = pattern.scale_context
    scale_factor = calculate_scale_factor(current_scale, target_scale)

    if scale_factor > 2.0:  # Need to scale up
        return enhance_pattern_for_scale(pattern, target_scale)
    elif scale_factor < 0.5:  # Need to scale down
        return simplify_pattern_for_scale(pattern, target_scale)
    else:  # Scale is compatible
        return pattern.with_scale_adjustments(target_scale)
