-Inference Script Example
-===================================
+Inference Script — AI Response Evaluation Environment
+=====================================================
 MANDATORY
-- Before submitting, ensure the following variables are defined in your environment configuration:
-    API_BASE_URL   The API endpoint for the LLM.
-    MODEL_NAME     The model identifier to use for inference.
-    HF_TOKEN       Your Hugging Face / API key.
-    LOCAL_IMAGE_NAME The name of the local image to use for the environment if you are using from_docker_image()
-                     method
-
-- Defaults are set only for API_BASE_URL and MODEL_NAME 
-    (and should reflect your active inference setup):
-    API_BASE_URL = os.getenv("API_BASE_URL", "<your-active-endpoint>")
-    MODEL_NAME = os.getenv("MODEL_NAME", "<your-active-model>")
-    
-- The inference script must be named `inference.py` and placed in the root directory of the project
-- Participants must use OpenAI Client for all LLM calls using above variables
+- Variables: API_BASE_URL, MODEL_NAME, HF_TOKEN, LOCAL_IMAGE_NAME
+- Defaults set only for API_BASE_URL and MODEL_NAME (not HF_TOKEN)
+- Must be named inference.py at repo root
+- Must use OpenAI client for all LLM calls
 
 STDOUT FORMAT
-- The script must emit exactly three line types to stdout, in this order:
-
     [START] task=<task_name> env=<benchmark> model=<model_name>
     [STEP]  step=<n> action=<action_str> reward=<0.00> done=<true|false> error=<msg|null>
     [END]   success=<true|false> steps=<n> rewards=<r1,r2,...,rn>
-
-  Rules:
-    - One [START] line at episode begin.
-    - One [STEP] line per step, immediately after env.step() returns.
-    - One [END] line after env.close(), always emitted (even on exception).
-    - reward and rewards are formatted to 2 decimal places.
-    - done and success are lowercase booleans: true or false.
-    - error is the raw last_action_error string, or null if none.
-    - All fields on a single line with no newlines within a line.
-
-  Example:
-    [START] task=click-test env=miniwob model=Qwen3-VL-30B
-    [STEP] step=1 action=click('123') reward=0.00 done=false error=null
-    [STEP] step=2 action=fill('456','text') reward=0.00 done=false error=null
-    [STEP] step=3 action=click('789') reward=1.00 done=true error=null
-    [END] success=true steps=3 rewards=0.00,0.00,1.00
