- Document gantt.sh unified CLI covering all API endpoints
- Separate API-based vs Supabase-direct approaches
- Clear usage examples for both methods

 **Source of truth for the pattern:**
 - **Location:** `/Users/mattbruce/Documents/Projects/OpenClaw/Web/gantt-board/scripts/`
-- **Files:** `gantt-task-crud.sh`, `attach-file.sh`, `view-attachment.sh`
-- **Usage:**
+- **Files:** 
+  - `gantt.sh` - Unified CLI (API-based, all operations)
+  - `gantt-task-crud.sh` - Direct Supabase CRUD
+  - `attach-file.sh` - Direct Supabase file attachments
+  - `view-attachment.sh` - View attached files
+
+**Usage (Unified CLI - covers ALL API endpoints):**
 ```bash
-./scripts/gantt-task-crud.sh list [status]      # List all tasks
-./scripts/gantt-task-crud.sh get <task-id>      # Get specific task
-./scripts/gantt-task-crud.sh create "Title" [status] [priority]
-./scripts/gantt-task-crud.sh update <task-id> <field> <value>
-./scripts/gantt-task-crud.sh delete <task-id>
+# Tasks
+./scripts/gantt.sh task list [status]              # List tasks
+./scripts/gantt.sh task get <task-id>              # Get task
+./scripts/gantt.sh task create "Title" [status] [priority]  # Create task
+./scripts/gantt.sh task natural "Fix bug by Friday, high priority"  # Natural language
+./scripts/gantt.sh task update <id> <field> <val>  # Update field
+./scripts/gantt.sh task delete <task-id>           # Delete task
+./scripts/gantt.sh task comment <id> "text"        # Add comment
+./scripts/gantt.sh task attach <id> <file>         # Attach file
+
+# Projects & Sprints
+./scripts/gantt.sh project list                    # List projects
+./scripts/gantt.sh sprint list                     # List sprints
+
+# Auth
+./scripts/gantt.sh auth session                    # Check session
+./scripts/gantt.sh auth login <email> <pass>       # Log in
+```
+
+**Usage (Direct Supabase - works without web server):**
+```bash
+./scripts/gantt-task-crud.sh list [status]         # List tasks
+./scripts/gantt-task-crud.sh get <task-id>         # Get task
 ./scripts/attach-file.sh <task-id> <file-path>     # Attach file
 ./scripts/view-attachment.sh <task-id> [index]     # View attachment
 ```
 
-**How it works:** Uses Supabase service role key directly. Files stored as base64 data URLs.
+**How it works:** 
+- `gantt.sh` uses the REST API (requires web server running)
+- Direct scripts use Supabase service role key (works offline)
+- Files stored as base64 data URLs in database
