=== HABIT TRACKER FEATURE PROGRESS === Date: 2026-02-10 Branch: feature/habit-tracker Repo: /home/moltbot/clawd ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ COMPLETED STORIES: [✓] Story 1.0: Define habits.json data schema Commit: ee8727a Date: 2026-02-10 Implementation: - Created dashboard/habits.json with proper schema - Root structure: lastUpdated (ISO timestamp) + habits (array) - Habit schema: id (string), name (string), frequency (daily/weekly), createdAt (ISO), completions (array of ISO dates) - Initial file contains empty habits array with current timestamp - All JSON validation passes Tests: - Created dashboard/test_habits_schema.py - Tests for file existence, valid JSON, root structure - Tests for lastUpdated ISO format validation - Tests for habits array type - Tests for complete habit schema (all required fields + types) - Tests for initial empty state - All tests pass ✓ Files modified: - dashboard/habits.json (created) - dashboard/test_habits_schema.py (created) [✓] Story 2.0: Backend API - GET /api/habits Commit: fc5ebf2 Date: 2026-02-10 Implementation: - Added GET /api/habits endpoint to dashboard/api.py - Endpoint returns habits array and lastUpdated timestamp - Graceful error handling: returns empty array if file missing/corrupt - Follows existing API patterns (similar to /api/git, /api/status) - Returns 200 status for all valid requests Tests: - Created dashboard/test_habits_api.py - Tests for endpoint existence (returns 200) - Tests for valid JSON response - Tests for response structure (habits array + lastUpdated) - Tests for ISO timestamp validation - Tests for empty file handling (returns [], not error) - Tests for habits with data - All 6 tests pass ✓ Files modified: - dashboard/api.py (added handle_habits_get method + route) - dashboard/test_habits_api.py (created) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CODEBASE PATTERNS: 1. JSON Data Files - Location: dashboard/*.json - Pattern: Similar structure to tasks.json, todos.json, issues.json - All use ISO timestamps for dates - Root objects contain metadata + data arrays 2. Testing Approach - Python test files in dashboard/ directory - Test naming: test_*.py - Comprehensive validation: existence, JSON validity, schema, types - Run tests from repo root with: python3 dashboard/test_*.py 3. Build Validation - Command: python3 -m py_compile dashboard/api.py - Validates Python syntax without executing 4. Utility Functions in api.py - Standalone utility functions placed before TaskBoardHandler class - Documented with docstrings (Args, Returns, Rules/behavior) - ISO timestamp parsing pattern: datetime.fromisoformat(ts.replace('Z', '+00:00')) - Convert to date only when time doesn't matter: dt.date() - Use try/except for robust parsing with sensible defaults (return 0, [], etc.) [✓] Story 3.0: Backend API - POST /api/habits (create habit) Commit: 3a09e6c Date: 2026-02-10 Implementation: - Added POST /api/habits endpoint to dashboard/api.py - Accepts {name, frequency} in request body - Returns 400 for missing name or empty name (after trim) - Returns 400 for invalid frequency (must be 'daily' or 'weekly') - Generates unique id following format 'habit-{millisecond_timestamp}' - Sets createdAt to current ISO timestamp - Initializes completions array as empty - Persists new habit to habits.json - Updates lastUpdated timestamp in habits.json - Returns 201 status with created habit object - Graceful handling of missing/corrupt habits.json file Tests: - Created dashboard/test_habits_post.py - Tests for successful habit creation (returns 201 + full habit object) - Tests for habit persistence to habits.json - Tests for correct id format (habit-{timestamp}) - Tests for missing name validation (400) - Tests for empty name validation (400) - Tests for invalid frequency validation (400) - Tests for missing frequency validation (400) - Tests for creating multiple habits (unique IDs) - Tests for lastUpdated timestamp update - All 9 tests pass ✓ Files modified: - dashboard/api.py (added handle_habits_post method + route) - dashboard/test_habits_post.py (created) [✓] Story 4.0: Backend API - Streak calculation utility Commit: 3927b7c Date: 2026-02-10 Implementation: - Created calculate_streak(completions, frequency) utility function - Added to dashboard/api.py as standalone function (before TaskBoardHandler class) - Accepts completions array (ISO timestamps) and frequency ('daily' or 'weekly') - Returns integer streak count (days for daily, weeks for weekly) - Daily habits: counts consecutive days without gaps - Weekly habits: counts consecutive weeks (7-day periods) - Returns 0 for no completions, invalid dates, or broken streaks - Edge case: today's completion counts even if streak was 0 yesterday - Edge case: multiple completions same day/week count as one period - Robust date parsing with error handling for invalid ISO timestamps Tests: - Created dashboard/test_habits_streak.py - Tests for no completions (returns 0) - Tests for daily single completion (today and yesterday) - Tests for daily consecutive days (5 days streak) - Tests for daily broken streak (gap detection) - Tests for daily old completion (>1 day ago returns 0) - Tests for weekly single completion (this week) - Tests for weekly consecutive weeks (4 weeks streak) - Tests for weekly broken streak (missing week) - Tests for weekly old completion (>7 days ago returns 0) - Tests for multiple completions same day (deduplicated) - Tests for today counting despite yesterday missing - Tests for invalid date format handling - Tests for weekly multiple in same week (deduplicated) - All 14 tests pass ✓ - All previous tests (schema, GET, POST) still pass ✓ Files modified: - dashboard/api.py (added calculate_streak function) - dashboard/test_habits_streak.py (created) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ NEXT STEPS: - Continue with remaining 14 stories ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
