Workflow State Memory (state-memory-mcp)

This project uses state-memory-mcp with project slug "world-model-mcp" to track tasks, decisions, blockers, and progress. ALWAYS update the state graph when performing work.

Mandatory Workflow

1. Start of session: Call manage_sessions(action: "start", agent_id: "..."), then run get_analytics(action: "summary") and manage_tasks(action: "next") BEFORE any coding.
2. Before work: Create or find the task node, set status to in_progress.
3. During work: Log decisions (manage_nodes(action: "create", type: "decision")), blockers (manage_nodes(action: "create", type: "blocker")), and notes (manage_nodes(action: "add_note")).
4. Visual Consistency (Dual Memory):
   • For UI / layout tasks, capture visual evidence using vision-memory-mcp:analyze_screenshot (pass trace_id: session_id for joint trajectory correlation).
   • Link visual proof via manage_edges(action: "link_visual", target_id: task_id, visual_state_id: vs_id, relationship: "renders_state").
   • Log visual blockers via manage_edges(action: "link_visual", target_id: blocker_id, visual_state_id: vs_id, relationship: "blocked_by_visual_state") or vision-memory-mcp:record_outcome(action_type: "blocker").
5. After work: Run run_diagnostics(action: "validate"), set task status to done via manage_tasks(action: "complete"), create artifact nodes, and call manage_sessions(action: "end").

Visual Memory (vision-memory-mcp)

This project utilizes vision-memory-mcp to cache visual states, record layout transitions, provide element grounding, and avoid repetitive LLM vision calls.

1. Mandatory Workflow & Priority

1. Orient: Call get_session_context to align your visual state context at the start of work.
2. Search: Call recall_memory (text/image search) before recreating duplicate UI state paths.
3. Ingest/Verify: ALWAYS call analyze_screenshot before querying any front-end vision models.
   • Cache Hit (is_known: true): Do NOT use vision models; read the returned description as context and use grounded_elements (selectors, coordinates) for action target selection.
   • Cache Miss (is_known: false): Query your vision model, then run analyze_screenshot with both the image and description to seed the cache.
4. Action Target Execution: Use predict_next_action to retrieve grounded_target handles (target_selector, target_coords) for deterministic UI clicks and typing.
5. Transitions: Call record_outcome after every click/type/scroll action to construct navigation paths.
6. Privacy & Cleanup: Call forget_state to purge sensitive or secret states from storage.

2. Tool Reference Summary (15 Core MCP Tools)

3. Agent Permissions & Auto-Run Configuration

To allow cache query and ingestion commands to run automatically without prompting:

• Google Antigravity (~/.gemini/config/config.json): Add these rules to your "globalPermissionGrants" -> "allow" list:
  • "command(vision-memory-mcp)" (Allow running the CLI without parameters prompts)
  • "read_file(.*\\.gemini/antigravity/brain/.*)" (Allow reading captured screenshots)
  • "write_file(.*\\.gemini/antigravity/brain/.*)" (Allow saving visual states)
• VS Code / Cursor IDE (settings.json): Ensure the agent has execution permissions for command(vision-memory-mcp) and read/write access to the workspace's local .vision-memory-mcp/ cache directory.

Spatial World Model (world-model-mcp)

This project uses world-model-mcp with project slug "world-model-mcp" to maintain a persistent 3D/2D spatial internal world model, entity tracking, object permanence, and movement simulation.

1. Mandatory Workflow & Priority

2. Entity Queries: Use query_entities (FTS5 search, proximity radius, or entity_id lookup) before creating duplicate objects.
3. Perception Bridging:
   • Ingest detected objects from vision models using ingest_observation.
   • Reconcile expected vs observed visual state using ingest_observation(reconcile: true).
4. Spatial Relations: Record topological containment, support, or proximity using set_relation (e.g. on, inside, next_to, contains).
5. Action Simulation & Validation: Before executing movement, call simulate_movement to verify path validity and avoid AABB obstacle collisions, or simulate_movement(mode: 'navigate') for waypoint planning.
