Week 2 Implementation Summary

Status: ✅ Complete

This document summarizes the Week 2 implementation of Developer Tools (Inspector, Recorder, Script Generator) for both Python and TypeScript SDKs.

What Was Implemented

Day 8: Inspector v1 ✅

Python (sentience/inspector.py):

• Console-based inspector that prints element info on mouse move
• Click detection that prints full element JSON
• Context manager support (with inspect(browser):)
• Integration with extension's element registry
• Shows: element id, role, text, bounding box

TypeScript (src/inspector.ts):

• Same functionality as Python version
• Type-safe implementation
• Async/await support

CLI Command:

• sentience inspect - Starts inspector mode
• Available in both Python and TypeScript

Day 9: Recorder v1 ✅

Python (sentience/recorder.py):

• Recorder class for capturing user actions
• Trace and TraceStep models matching spec
• Records: navigation, click, type, press events
• Text masking for sensitive data (password, email patterns)
• Optional snapshot capture at each step
• Save/load trace to/from JSON

TypeScript (src/recorder.ts):

• Same functionality as Python version
• Trace and TraceStep interfaces
• Async methods for recording

CLI Command:

• sentience record [--url URL] [--output trace.json] [--snapshots] [--mask pattern]
• Available in both Python and TypeScript

Day 10: Script Generator v1 ✅

Python (sentience/generator.py):

• ScriptGenerator class converts trace to code
• Generates Python scripts using SDK API
• Generates TypeScript scripts using SDK API
• Prefers semantic selectors over element IDs
• Falls back to element IDs with TODO comments
• Clean, readable output code

TypeScript (src/generator.ts):

• Same functionality as Python version
• Type-safe implementation

CLI Command:

• sentience gen <trace.json> [--lang py|ts] [--output script.py]
• Available in both Python and TypeScript

Day 11: Smart Selector Inference ✅

Python (sentience/recorder.py):

• _infer_selector() method with heuristics:
  • Builds selectors: role=... text~"..."
  • Uses name/aria-label/placeholder if text empty
  • Includes clickable=true when relevant
  • Validates selector against snapshot (should match 1 element)
  • Adds constraints if multiple matches

TypeScript (src/recorder.ts):

• inferSelector() method with same heuristics
• Integrated into recordClick() and recordType()

Features

Inspector

• ✅ Console output on mouse move (element id, role, text, bbox)
• ✅ Full element JSON on click
• ✅ Context manager support
• ✅ Cleanup on stop

Recorder

• ✅ Records navigation, click, type, press events
• ✅ Trace format matches spec (Trace, TraceStep)
• ✅ Text masking for sensitive data
• ✅ Optional snapshot capture
• ✅ Save/load trace to JSON
• ✅ Smart selector inference (Day 11)

Script Generator

• ✅ Generates Python code
• ✅ Generates TypeScript code
• ✅ Uses semantic selectors when available
• ✅ Falls back to element IDs with TODO comments
• ✅ Clean, executable output

Smart Selector Inference

• ✅ Heuristics for robust selectors
• ✅ Validates selectors against snapshots
• ✅ Handles edge cases (no text, multiple matches)

Testing

All features have comprehensive tests:

• Inspector: 4 test cases (start/stop, context manager, mouse move, click)
• Recorder: 8 test cases (start/stop, navigation, click, type, masking, press, save/load, format)
• Generator: 6 test cases (Python/TS generation, save, no selector, helper function)
• Smart Selector: 3 test cases (inference, with text, validation)

CLI Usage

Python

# Inspector
sentience inspect

# Recorder
sentience record --url https://example.com --output trace.json

# Generator
sentience gen trace.json --lang py --output script.py

TypeScript

# Inspector
npm run cli inspect

# Recorder
npm run cli record --url https://example.com --output trace.json

# Generator
npm run cli gen trace.json --lang ts --output script.ts

Next Steps

Week 2 is complete! Ready for:

• Week 3: Polish & Demo
• Phase 2: TypeScript SDK MVP (if not already done)
• Phase 3: Enhanced Query Engine
• Phase 4: Verified Action Layer
