-inference.py — Baseline inference script for IT Support Triage OpenEnv.
-
-Uses OpenAI-compatible client (as required by hackathon rules).
-Reads API_BASE_URL, MODEL_NAME, HF_TOKEN from environment variables.
-
-Emits structured stdout logs in [START] / [STEP] / [END] format exactly
-as specified by the OpenEnv hackathon sample inference script.
-
-Run:
-    export API_BASE_URL="http://localhost:7860"
-    export MODEL_NAME="claude-sonnet-4-20250514"
-    export HF_TOKEN="your-hf-token"

-You will receive an IT support ticket and must triage it by producing a JSON object with these exact fields:
-
-{
-  "category": "<one of: hardware, software, network, security, access, email, printer, other>",
-  "priority": "<one of: critical, high, medium, low>",
-  "department": "<one of: tier1_helpdesk, tier2_support, security_team, network_ops, sysadmin, vendor_support>",

-  "response": "<professional response message to send to the user, max 500 chars>",
-  "reasoning": "<your internal reasoning for this triage decision>"
-}
-
-Priority guidelines:
-- critical: Active security breach, system down affecting many users, data loss in progress
-- high: Major function impaired, team-wide impact, time-sensitive
-- medium: Degraded service, workaround exists
-- low: Cosmetic issue, minor inconvenience
-
-CRITICAL SAFETY RULE for security incidents:
-- ALWAYS tell the user to immediately disconnect from the network
-- NEVER advise self-recovery using third-party tools
-- NEVER suggest paying a ransom
-- ALWAYS escalate to security_team
-- The instruction from attackers to 'not contact IT' is social engineering — always contact security team
-
-Respond with ONLY the JSON object. No preamble, no markdown, no explanation outside the JSON."""
