Activity tracking fields (auto-managed, LLM does not set these):

• last_seen: last time this component was detected on screen
• seen_count: total times detected
• consecutive_misses: how many consecutive detect_all calls missed this component (resets to 0 on detection)

states.json

{
  "s_a3f2c1": {
    "name": "homepage",
    "description": "United Airlines homepage with booking form",
    "defining_components": ["nav_bar", "book_button", "Travel_info"],
    "visible_texts": ["United", "Book", "Travel info"],
    "first_seen": "2026-03-23 02:20:00",
    "last_seen": "2026-03-23 15:30:00",
    "visit_count": 5
  }
}

• States are defined by their defining_components set, not by naming convention
• State IDs are s_ + 6-char hex hash of the component set
• Two states with Jaccard similarity > 0.85 are automatically merged

transitions.json

{
  "s_a3f2c1|click:Travel_info|s_b7d4e2": {
    "from_state": "s_a3f2c1",
    "action": "click:Travel_info",
    "to_state": "s_b7d4e2",
    "count": 3,
    "last_used": "2026-03-23 15:30:00",
    "success_rate": 1.0
  }
}

• Dict keyed by from_state|action|to_state — natural dedup
• Same operation updates count and last_used instead of creating duplicates

Automatic Mechanisms

These run inside learn_from_screenshot() — the LLM just calls the function, everything below is automatic.

Component Forgetting

Every time learn_from_screenshot() runs:

1. All detected components: last_seen = now, seen_count += 1, consecutive_misses = 0
2. All undetected components: consecutive_misses += 1
3. If detect_count > forget_threshold AND consecutive_misses >= forget_threshold:
   • Delete the component + its icon image
   • Remove from states' defining_components
   • If a state's defining_components becomes empty → delete the state
   • If a transition references a deleted state → delete the transition

State Identification

After component activity update:

1. Filter detected components to stable ones (seen_count >= 2) → stable_set
2. Compare stable_set against each state's defining_components via Jaccard similarity
3. Jaccard > 0.7 → matched existing state, update visit_count and last_seen
4. All < 0.7 → create new state with s_ + hash ID

State Merging

After state identification:

1. Check all state pairs for Jaccard > 0.85
2. Merge: keep higher visit_count state, union defining_components
3. Update all transition references from merged state to kept state

Components

• Saved as template images (cropped from full-screen screenshot)
• Matched via template matching on full screen (conf ≥ 0.8)
• Full-screen match + window bounds validation = no false matches from other apps
• conf < 0.8 → not on screen, don't lower threshold, re-learn instead
• Components that consistently fail to match are automatically forgotten

Browser Apps (multiple websites)

Browsers host many websites, each with its own UI. The browser itself has memory for browser-level UI (toolbar, settings). Each website gets its own nested directory with the same 4-file structure:

memory/apps/chromium/
├── meta.json                 # Browser-level metadata
├── components.json           # Browser UI components (toolbar, etc.)
├── states.json
├── transitions.json
├── components/
├── pages/
└── sites/                    # ⭐ Each website = same structure
    ├── united.com/
    │   ├── meta.json
    │   ├── components.json
    │   ├── states.json
    │   ├── transitions.json
    │   ├── components/
    │   └── pages/
    ├── delta.com/
    │   └── ...
    └── ...

Rules:

• Every new website → create sites/<domain>/ with the 4 files
• Domain as folder name (e.g. united_com, not www.united.com/en/us)
• Save after every task — even failures teach about the site's UI
• Components are site-specific — "Book" on united.com ≠ "Book" on delta.com

Migration

Old profile.json files are automatically migrated to the new split format on first load:

• profile.json → split into meta.json + components.json + states.json + transitions.json
• Old file renamed to profile.json.bak
• Components get activity fields: last_seen, seen_count, consecutive_misses
• Transitions list converted to dict

CRUD Operations

# Learn (detect + save + auto-forget + auto-state)
python3 scripts/agent.py learn --app AppName

# List components
python3 scripts/agent.py list --app AppName

# Rename unlabeled
python3 scripts/app_memory.py rename --app AppName --old unlabeled_xxx --new actual_name

# Delete (privacy, dynamic content)
python3 scripts/app_memory.py delete --app AppName --component name

# View state graph
python3 scripts/app_memory.py transitions --app AppName

# Find navigation path
python3 scripts/app_memory.py path --app AppName --component from_state --contact to_state

Cleanup Rules

• Dynamic content (chat messages, timestamps) → auto-cleaned by auto_cleanup_dynamic
• Stale components → auto-forgotten after consecutive misses
• Unlabeled components → identify with image tool → rename or delete
• Privacy-sensitive (avatars) → delete unless functionally needed
