+# Support Ticket Triage Environment
+
+A real-world customer support ticket management environment for AI agents built with the OpenEnv framework. This environment simulates a customer support workflow where AI agents must triage, categorize, prioritize, and respond to support tickets.
+
+## 🎯 Overview
+
+This environment tests an AI agent's ability to handle realistic customer support scenarios including:
+
+- **Ticket Categorization**: Classifying tickets into correct departments (Technical, Billing, Account, etc.)
+- **Priority Assignment**: Determining urgency levels based on ticket content
+- **Response Generation**: Crafting appropriate customer responses
+- **Escalation Decisions**: Knowing when to escalate to specialized teams
+- **Workflow Management**: Handling multiple tickets efficiently
+
+## 📋 Tasks
+
+The environment includes three tasks with increasing difficulty:
+
+### 1. Ticket Categorization (Easy)
+- **Task ID**: `categorize_ticket`
+- **Max Steps**: 5
+- **Description**: Categorize incoming support tickets into the correct department and priority level
+- **Skills Tested**: Content analysis, classification, priority assessment
+
+### 2. Prioritize and Route (Medium)
+- **Task ID**: `prioritize_and_route`
+- **Max Steps**: 10
+- **Description**: Handle multiple tickets by prioritizing them correctly and routing to appropriate teams
+- **Skills Tested**: Multi-task management, prioritization, routing decisions
+
+### 3. Full Support Workflow (Hard)
+- **Task ID**: `full_workflow`
+- **Max Steps**: 15
+- **Description**: Complete end-to-end support workflow including categorization, prioritization, drafting responses, and escalation when necessary
+- **Skills Tested**: Complete customer support workflow, professional communication, judgment
+
+## 🏗️ Architecture
+
+### Observation Space
+
+The agent receives observations containing:
+
+```python
+{
+    "tickets": [
+        {
+            "id": "ticket_id",
+            "customer_name": "Customer Name",
+            "customer_email": "customer@example.com",
+            "subject": "Ticket subject",
+            "content": "Full ticket content",
+            "status": "new|in_progress|waiting_customer|resolved|escalated|closed",
+            "category": "technical|billing|account|general|sales|urgent",  # if set
+            "priority": "low|medium|high|critical",  # if set
+            "responses": ["response1", "response2"],  # if any
+            "assigned_team": "team_name"  # if escalated
+        }
+    ],
+    "current_step": 0,
+    "max_steps": 10,
+    "queue_status": {
+        "new": 2,
+        "in_progress": 1,
+        "resolved": 0,
+        "escalated": 0
+    },
+    "available_actions": ["categorize", "prioritize", "respond", "escalate", "request_info", "close"],
+    "instructions": "Task description",
+    "last_action_result": "Result of previous action"
+}
+```
+
+### Action Space
+
+The agent can take the following actions:
+
+```python
+{
+    "action_type": "categorize|prioritize|respond|escalate|request_info|close",
+    "ticket_id": "ticket_id_to_act_on",
+    "category": "technical|billing|account|general|sales|urgent",  # for categorize
+    "priority": "low|medium|high|critical",  # for categorize/prioritize
+    "response_text": "Response message to customer",  # for respond/request_info
+    "escalation_reason": "Reason for escalation",  # for escalate
+    "target_team": "senior_support|engineering|management|billing_team"  # for escalate
+}
+```
+
+### Reward Function
+
+The environment provides dense rewards (0.0 to 1.0) based on:
+
+1. **Categorization Accuracy** (60% weight):
+   - Correct category: 0.6 points
+   - Related category: 0.3 points

+4. Draft professional responses
+5. Make escalation decisions when needed
+6. Manage ticket lifecycle from new to closed
+
+### Task Progression
+
+1. **Easy Task** - Single skill focus: Categorization accuracy
+2. **Medium Task** - Multi-skill: Categorization + Prioritization + Routing
+3. **Hard Task** - Full workflow: All skills including responses and escalations
+
+### Grading System
+
+**Categorization (60% weight)**:
+- Correct category: 0.6 points
+- Related category: 0.3 points
+- Correct priority: 0.4 points
+- Close priority: 0.2 points
+
+**Response Quality**:
+- Relevant keywords: 60% of score
+- Professionalism: 20% of score
+- Appropriate length: 20% of score
+
+**Escalation Judgment**:
+- Appropriate escalation: 0.5-0.7 points
+- Over-escalation penalty: 0.1 points

+### Support Ticket Triage Environment
+
+This environment simulates a customer support workflow where AI agents must:
+1. **Categorize** tickets into correct departments
+2. **Prioritize** based on urgency
+3. **Respond** to customers professionally
+4. **Escalate** when necessary
+5. **Close** resolved tickets
+
+#### Available Actions:
+
+1. **categorize** - Set category and priority for a ticket
+   ```json
+   {"action_type": "categorize", "ticket_id": "abc123", "category": "technical", "priority": "high"}
+   ```
+
+2. **prioritize** - Set priority for a ticket
+   ```json
+   {"action_type": "prioritize", "ticket_id": "abc123", "priority": "critical"}
+   ```
+
+3. **respond** - Send a response to the customer
+   ```json
+   {"action_type": "respond", "ticket_id": "abc123", "response_text": "Thank you for contacting support..."}
+   ```
+
+4. **escalate** - Escalate to a specialized team
+   ```json
+   {"action_type": "escalate", "ticket_id": "abc123", "escalation_reason": "Complex technical issue", "target_team": "engineering"}
+   ```
+
+5. **request_info** - Ask customer for more information
+   ```json
+   {"action_type": "request_info", "ticket_id": "abc123", "response_text": "Could you please provide more details..."}
+   ```
+
+6. **close** - Close a resolved ticket
+   ```json
+   {"action_type": "close", "ticket_id": "abc123"}
+   ```
+
+#### Categories:
+- technical, billing, account, general, sales, urgent

+# Checks that your HF Space is live, Docker image builds, and openenv validate passes.
+#
+# Prerequisites:
+#   - Docker:       https://docs.docker.com/get-docker/
+#   - openenv-core: pip install openenv-core
+#   - curl (usually pre-installed)
+#
+# Run:
+#   ./validate-submission.sh <ping_url> [repo_dir]
+#
+#   Or download and run locally:

+#     ./validate-submission.sh <ping_url> [repo_dir]
+#
+# Arguments:
+#   ping_url   Your HuggingFace Space URL (e.g. https://your-space.hf.space)
+#   repo_dir   Path to your repo (default: current directory)
+#
+# Examples:
