+# Dynamic Analyzer Implementation Summary
+
+## Overview
+
+Successfully implemented a comprehensive dynamic documentation analyzer that combines LLM-powered analysis with live browser execution to generate validated, canonical Doc Detective tests from unclear documentation.
+
+## Implementation Completed
+
+### Core Modules Created
+
+1. **`src/analyzer/browser-context.js`** (235 lines)
+   - `extractBrowserContext(driver)` - Extracts comprehensive page state via WebDriver
+   - `formatContextForPrompt(context)` - Formats browser context for LLM consumption
+   - Queries: URL, title, forms, inputs, buttons, links, headings, visible text
+   - Robust error handling with graceful fallback
+
+2. **`src/analyzer/user-query.js`** (267 lines)
+   - `queryUser(message, options)` - General user prompt with inquirer
+   - `queryLowConfidenceStep(step, confidence, browserContext)` - Handles low-confidence steps
+   - `queryCredentials(credentialNames, envFilePath)` - Manages credential placeholders
+   - `queryStepFailure(step, result, retryCount, maxRetries)` - Failure decision prompts
+   - `queryInitialUrl(suggestedUrl, instruction)` - Initial URL confirmation
+   - Rich console UI with emojis and formatting
+
+3. **`src/analyzer/dynamic-prompt-builder.js`** (170 lines)
+   - `buildDynamicPrompt(instruction, browserContext, previousResult, completedSteps)` - Context-aware prompts

+
+4. **`src/analyzer/step-executor.js`** (215 lines)
+   - `executeStepWithRetry(step, driver, config, runStepFn, context, options)` - Retry orchestration
+   - `validateStepPreExecution(step, driver)` - Pre-execution element validation
+   - `applyHeuristicRefinement(step, result, retryCount)` - Intelligent selector adjustments
+   - `refineWithLlm(step, result, browserContext, config)` - LLM-guided refinement (optional)
+   - Three retry strategies: wait, selector adjustment, final attempt
+
+5. **`src/analyzer/dynamic-analyzer.js`** (475 lines)
+   - `dynamicAnalyze(document, config, driver)` - Main orchestrator
+   - Complete workflow: static analysis → iterative refinement → execution → validation

+   - Comprehensive metadata tracking (tokens, retries, interventions, timing)
+   - Error handling and recovery
+
+### Supporting Files

+
+### Dependencies Added
+
+- **`doc-detective-core@^3.4.1`** - Test execution engine
+- **`inquirer@^8.2.6`** - Interactive CLI prompts
+- **`chai@^4.3.10`** - Test assertions (downgraded from 6.x for CommonJS compatibility)
+
+### Exports Updated
+
+Added to `src/index.js`:
+```javascript
+exports.dynamicAnalyze = require("./analyzer/dynamic-analyzer").dynamicAnalyze;
+```
+
+## Key Features Implemented
+
+### 1. Context-Aware Step Generation
+- Extracts live DOM state (forms, inputs, buttons, links)
+- Builds prompts with current page structure
+- LLM generates precise selectors based on actual elements
+- Confidence scoring (0-1) for every generated step
+
+### 2. Interactive User Queries
+- **Low Confidence (<0.7)**: Prompts user to continue/skip/abort
+- **Credentials Detected**: Guides placeholder usage and .env setup
+- **Step Failures**: Asks to retry/skip/abort after max retries
+- **Initial URL**: Confirms/modifies starting URL if not detected
+- JSON view option for technical users
+
+### 3. Intelligent Retry Logic
+Three heuristic refinement strategies:
+- **Retry 1**: Add implicit wait (timing issues)
+- **Retry 2**: Adjust selectors (`#id` → `[id="id"]`, `.class` → `[class*="class"]`)
+- **Retry 3**: Final attempt with most flexible selectors
+- Optional LLM-guided refinement (`useLlmRefinement: true`)
+
+### 4. Credential Management
+- Detects `$USERNAME`, `$PASSWORD`, `$API_KEY`, etc.
+- Generates placeholder variables
+- Injects `loadVariables` step automatically
+- Provides .env file instructions
+
+### 5. Comprehensive Metadata
+Tracks and returns:
+- Token usage (prompt, completion, total)
+- Retry counts per step
+- User interventions (type, timestamp, decision)
+- Execution time
+- Steps analyzed/executed/failed/skipped
+
+### 6. Robust Error Handling
+- Graceful fallback for browser context extraction failures
+- Exception handling in step execution
+- LLM call error recovery
+- Driver session management
+

+## Usage Example
+
+```javascript
+const { dynamicAnalyze } = require('doc-detective-resolver');
+
+// Initialize driver (from doc-detective-core)
+const driver = await initializeDriver(config);
+
+// Documentation to analyze
+const doc = `
+Sign in to Heretto CCMS with credentials.
+In the left pane, click Content folder.
+Create a new folder named Testing.
+`;
+
+// Configuration
+const config = {
+  provider: 'anthropic',
+  apiKey: process.env.ANTHROPIC_API_KEY,
+  userQueryThreshold: 0.7,
+  maxRetries: 3,
+  useLlmRefinement: false
+};
+
+// Run dynamic analysis
+const result = await dynamicAnalyze(doc, config, driver);
+
+console.log(result.test.steps);     // Validated steps
+console.log(result.metadata);       // Execution metadata
+```
+
+## Output Format
+
+```javascript
+{
+  test: {
+    testId: "uuid",
+    description: "Dynamic test generated from...",
+    steps: [

+## Known Limitations
+
+1. **Requires Initialized Driver**: Caller must provide WebDriverIO driver instance
+2. **Interactive Mode Only**: Requires user input, not fully automated
+3. **LLM API Required**: Needs API key for Anthropic/OpenAI/Google
+4. **Token Costs**: Each step refinement consumes API tokens
+5. **Single Browser Session**: Assumes clean state, doesn't handle complex auth flows
+6. **Mock Execution**: Uses fallback mock when doc-detective-core unavailable (for dev)
