Superwise Drift Detection Skill

When the user wants to set up drift detection for their model, guide them through the steps below in order. Complete each step before moving to the next.

What You Need From the User

Ask the user to provide the following before starting:

1. Superwise credentials — SUPERWISE_CLIENT_ID and SUPERWISE_SECRET_TOKEN (found in their Superwise account under Settings → API Keys)
2. Training CSV — the CSV file their model was trained on (feature columns only; a row_id column will be added automatically)
3. Model name — a short label with no spaces (e.g. my_churn_model); used to name datasets in Superwise
4. Inference endpoint — one of two options:
   • Option A: They already have a running model endpoint. Ask for the URL. It must return JSON shaped as {"records": [{...}, ...]} where each record contains the same columns as the training CSV.
   • Option B: They need to deploy one. Use the dc-bikeshare example in examples/dc-bikeshare-drift/app.py as a template. Guide them to adapt predict.py for their model, then run python app.py locally. Set INFERENCE_ENDPOINT_URL=http://localhost:5001/predict for local testing.

Step 1 — Install dependencies

pip install -r requirements.txt

Create a .env file in the skill root directory with the following contents, filling in the values the user provided:

SUPERWISE_CLIENT_ID=\x3Cfrom user>
SUPERWISE_SECRET_TOKEN=\x3Cfrom user>
MODEL_NAME=\x3Cmodel name>
INFERENCE_ENDPOINT_URL=\x3Cfrom user's answer to question 4>
SUPERWISE_AUTO_TRIGGER=true
SUPERWISE_TRAINING_DATASET_ID=
SUPERWISE_TRAINING_DATASET_NAME=
SUPERWISE_TRAINING_CUBE_NAME=
SUPERWISE_INFERENCE_DATASET_ID=
SUPERWISE_INFERENCE_DATASET_NAME=
SUPERWISE_INFERENCE_CUBE_NAME=
SUPERWISE_DRIFT_POLICY_ID=
SCHEDULE_HOUR_UTC=6
SCHEDULE_MINUTE_UTC=0
PORT=5000

The dataset and policy ID fields will be filled in after Steps 2 and 3.

Step 2 — Create Superwise datasets and upload training data

python setup_dataset.py \
    --training-csv path/to/training.csv \
    --model-name their_model_name

This creates a training dataset and an inference dataset in Superwise, uploads the training CSV row by row, and prints the dataset IDs and cube names.

Copy the printed values into .env:

SUPERWISE_TRAINING_DATASET_ID=\x3Cprinted value>
SUPERWISE_TRAINING_DATASET_NAME=\x3Cprinted value>
SUPERWISE_TRAINING_CUBE_NAME=\x3Cprinted value>
SUPERWISE_INFERENCE_DATASET_ID=\x3Cprinted value>
SUPERWISE_INFERENCE_DATASET_NAME=\x3Cprinted value>
SUPERWISE_INFERENCE_CUBE_NAME=\x3Cprinted value>

Note: training CSV column names must use only letters, numbers, and underscores, and must start with a letter. Warn the user if any column names violate this.

Step 3 — Create drift policies

python setup_drift_policy.py \
    --training-csv path/to/training.csv \
    --policy-name their_model_drift

This creates one Jensen-Shannon divergence policy per categorical (string/boolean) column in the training CSV, comparing the training dataset against the inference dataset. Numeric columns are skipped with a warning — this is a known Superwise platform limitation (wasserstein distance for numeric columns is not yet supported).

Copy the primary printed policy ID into .env:

SUPERWISE_DRIFT_POLICY_ID=\x3Cprinted value>

If the user wants to monitor only specific columns, add --columns col1 col2 col3.

Step 4 — Run an end-to-end drift check

python -c "
import os; os.chdir('.')
from dotenv import load_dotenv; load_dotenv()
from skill import run
result = run()
print(result)
"

This will:

1. Fetch inference records from INFERENCE_ENDPOINT_URL
2. Ingest them into the Superwise inference dataset
3. Trigger the drift policy evaluation
4. Poll until the evaluation completes
5. Send an alert via OpenClaw's Telegram connection if drift is detected
6. Print a summary

Step 5 — Schedule recurring drift checks

Register the skill with OpenClaw using the metadata in skill.py:

• Trigger command: /drift_check
• Schedule: 0 6 * * * (06:00 UTC daily — adjust to the user's inference cadence)
• Alerts: routed through OpenClaw's existing Telegram connection

For a production deployment, guide the user to deploy scheduler.py to Render using the included render.yaml. Set all .env values as Render environment variables.

Telegram Alerts

This skill uses OpenClaw's existing Telegram connection — no separate bot setup needed. The _send_telegram() function in skill.py uses TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID from the user's OpenClaw environment. If the user does not have Telegram set up in OpenClaw yet, point them to OpenClaw's Telegram setup docs.

Drift alerts look like:

• Unhealthy: lists features with high drift (score > 0.2), flags that predictions may be unreliable
• Healthy: confirms no significant drift with per-feature scores

Reference Example: DC Bikeshare

examples/dc-bikeshare-drift/ is a complete working example the user can run to verify the skill end-to-end before connecting their own model:

cd examples/dc-bikeshare-drift
pip install -r requirements.txt
python collect_training_data.py   # fetch real station data, generate synthetic history
python train.py                   # train RandomForest classifier
python app.py                     # start local Flask inference server on port 5001

Then run the drift check from the skill root with:

INFERENCE_ENDPOINT_URL=http://localhost:5001/predict

This example uses only categorical features (station size, e-bike presence, hour of day, day type, season) to predict bike availability — all suitable for JSD drift detection.

Retraining

When the user retrains their model:

python setup_dataset.py \
    --training-csv path/to/new_training.csv \
    --model-name their_model_name \
    --retrain

This creates a versioned replacement training dataset and preserves the inference history. Update .env with the new training dataset ID and cube name, then re-run setup_drift_policy.py to create a new policy pointing at the updated baseline.

Troubleshooting

• Policy stays pending forever: Check that inference records were successfully ingested before triggering. The inference dataset must have data for the policy to evaluate.
• unhealthy on first run: Expected if inference records are a single time-slice snapshot (all same hour/day/season). Accumulate inference records over time for a more representative distribution.
• Numeric columns skipped: Wasserstein distance for numeric dimensions is a known Superwise platform bug. Use categorical bucketing as a workaround, or wait for the Superwise platform fix.
• CubeJS cube not found after upload: New datasets take a few minutes to register in Superwise's CubeJS layer. Wait 2–3 minutes and retry verification.
