Conversation

Conversation Skill

Provides natural language processing for understanding user intent, managing conversation context, resolving references, and maintaining conversation history.

Responsibilities

1. Intent Classification - Determine what the user wants
2. Reference Resolution - Resolve "it", "that", "this" to actual feature names
3. Entity Extraction - Extract features, domains, subtasks mentioned
4. Ambiguity Detection - Identify unclear requests and ask clarifying questions
5. Context Management - Track conversation state, detect context loss
6. Routing - Route to appropriate handler
7. History Tracking - Maintain conversation history for context

Intent Classification

function classify_intent(
  message: string,
  conversation_history: ConversationMessage[],
  product_spec: ProductSpec
): IntentClassification {
  const patterns = {
    feature_request: /(?:add|create|implement|build|new|feature|support|enable)/i,
    bug_report: /(?:bug|broken|error|issue|problem|wrong|doesn't work|fix)/i,
    question: /(?:how|what|where|when|why|who|which|can you|explain)/i,
    clarification: /(?:what do you mean|clarify|elaborate|more detail)/i,
    status_update: /(?:status|progress|where are we|what's left)/i,
    mind_change: /(?:actually|wait|never mind|forget that|change|instead)/i,
    context_switch: /(?:let's talk about|switching to|moving on|about)/i,
    approval: /(?:yes|ok|sure|go ahead|approved|sounds good|let's do it)/i,
    rejection: /(?:no|stop|don't|cancel|never mind)/i,
    pause: /(?:pause|hold on|wait|brb|later)/i,
    continue: /(?:continue|resume|let's continue|back)/i
  };

  const scores = {};
  for (const [intent, pattern] of Object.entries(patterns)) {
    const matches = message.match(pattern);
    scores[intent] = matches ? matches.length * 0.3 : 0;
  }

  const topIntent = Object.entries(scores).reduce((a, b) => a[1] > b[1] ? a : b);

  return {
    intent: topIntent[0],
    confidence: topIntent[1],
    alternative_intents: Object.entries(scores)
      .filter(([_, score]) => score > 0.3)
      .sort((a, b) => b[1] - a[1])
      .slice(1, 4)
      .map(([intent, score]) => ({ intent, confidence: score }))
  };
}

Entity Extraction

function extract_feature_mention(
  message: string,
  product_spec: ProductSpec
): FeatureMention {
  const mentioned = [];

  // Direct feature name matches
  if (product_spec.features) {
    for (const [featureId, feature] of Object.entries(product_spec.features)) {
      const featureName = feature.name || featureId;
      if (message.toLowerCase().includes(featureName.toLowerCase())) {
        mentioned.push({
          type: 'direct',
          feature_id: featureId,
          feature_name: featureName,
          confidence: 0.9
        });
      }
    }
  }

  // Domain and nested feature matches
  if (product_spec.domains) {
    for (const [domainId, domain] of Object.entries(product_spec.domains)) {
      if (message.toLowerCase().includes(domain.name.toLowerCase())) {
        mentioned.push({
          type: 'domain',
          domain_id: domainId,
          domain_name: domain.name,
          confidence: 0.85
        });
      }

      if (domain.features) {
        for (const [featureId, feature] of Object.entries(domain.features)) {
          const featureName = feature.name || featureId;
          if (message.toLowerCase().includes(featureName.toLowerCase())) {
            mentioned.push({
              type: 'feature',
              domain_id: domainId,
              feature_id: featureId,
              feature_name: featureName,
              confidence: 0.9
            });
          }
        }
      }
    }
  }

  // Subtask references
  const subtaskMatch = message.match(/(?:subtask|task|item)\s+(\d+)/i);
  if (subtaskMatch) {
    mentioned.push({
      type: 'subtask_reference',
      reference: subtaskMatch[1],
      confidence: 0.7
    });
  }

  if (mentioned.length === 0) return { type: 'none', confidence: 0 };
  return mentioned.sort((a, b) => b.confidence - a.confidence)[0];
}

Ambiguity Detection

function detect_ambiguity(message: string): AmbiguityAnalysis {
  const ambiguities = [];
  let confidence = 0;

  // Pronouns without context
  const pronouns = message.match(/\b(it|that|this|they|them|those)\b/gi);

      severity: 'high',
      text: pronouns[0],
      message: 'Pronoun at start of message without clear referent'
    });
    confidence = 0.8;
  }

  // Vague actions
  const vagueMatch = message.match(/\b(fix|update|change|improve|handle)\b\s+(?:it|that|this)/i);
  if (vagueMatch) {
    ambiguities.push({
      type: 'vague_action',
      severity: 'medium',
      text: vagueMatch[0],
      message: 'Action verb without specific target'
    });
    confidence = Math.max(confidence, 0.6);
  }

  // Multiple actions
  const actionWords = message.split(/\s+/).filter(word =>
    /^(add|create|fix|update|delete|remove|test|check|verify|deploy|build|run)/i.test(word)
  );
  if (actionWords.length > 2) {
    ambiguities.push({
      type: 'multiple_actions',
      severity: 'medium',
      text: actionWords.join(', '),
      message: 'Multiple actions detected, unclear priority'
    });
    confidence = Math.max(confidence, 0.7);
  }

  return {
    is_ambiguous: ambiguities.length > 0,
    confidence,
    ambiguities,
    suggestion: ambiguities.length > 0 ? 'Could you please provide more specific details?' : null
  };
}

Reference Resolution

function resolve_references(
  message: string,
  conversation_history: ConversationMessage[],
  state: ConversationState
): ResolvedMessage {
  let resolved = message;
  const references = [];

  // Replace pronouns with actual referents
  const pronounMap = {

    if (referent) {
      const pattern = new RegExp(`\\b${pronoun}\\b`, 'gi');
      if (pattern.test(message)) {
        resolved = resolved.replace(pattern, referent);
        references.push({ original: pronoun, resolved: referent, type: 'pronoun' });
      }
    }
  }

  // Replace definite references
  const definiteReferences = {
    'the feature': state.current_feature?.feature_name,
    'the bug': state.last_action?.type === 'bug_fix' ? state.last_action.description : null,
    'the task': state.current_feature?.subtask_id
  };

  for (const [phrase, referent] of Object.entries(definiteReferences)) {
    if (referent) {
      resolved = resolved.replace(new RegExp(phrase, 'gi'), referent);
      references.push({ original: phrase, resolved: referent, type: 'definite_reference' });
    }
  }

  return {
    original: message,
    resolved,
    references,
    confidence: references.length > 0 ? 0.85 : 1.0
  };
}

Context Management
