 # Dataset Card for Stargazer
 
-Stargazer is a benchmark for exoplanet detection from radial-velocity time series. Each row is one benchmark task with the original task payload preserved.
+Stargazer is a scalable environment for evaluating AI agents on dynamic, iterative physics-grounded model-fitting tasks using inference on radial-velocity (RV) time series data.

 ## Overview
 
+Stargazer comprises 120 tasks across three difficulty tiers, including 20 real archival cases, covering diverse scenarios ranging from high-SNR single-planet systems to complex multi-planetary configurations requiring involved low-SNR analysis.

+## Usage
+
+To run a single task by ID using the official repository:
+
+```bash
+python run_agent_batch_hard_timeout.py \
+    --model gpt-5-mini \
+    --task-ids seed22_diff4 \
+    --verbose \
+    --output-dir results_debug
+```
+
+To run all difficulty-1 tasks with 10 parallel workers:
+
+```bash
+python run_agent_batch_hard_timeout.py \
+    --model gpt-5-mini \
+    --count 1000 \
+    --difficulties 1 \
+    --workers 10 \
+    --output-dir results_diff1
+```
 
 ## What Each Row Contains

 - Tasks in this release may contain up to 7 planets
 - This is a benchmark release, not a training corpus
 - Ground-truth configuration fields are included, so they should not be exposed to the evaluated agent
