Declare the pipeline from data source to predictor as a **skrub DataOps graph** (not as a bare `sklearn.Pipeline`). Every step is either a pure-Python function (stateless) attached via `.skb.apply_func`, or a sklearn-compatible estimator (stateful) attached via `.skb.apply`. Stops at the declared object — no fit, split, tuning, persistence, or evaluation. TRIGGER — any of: - Writing or editing code that declares any link in the chain *data source → predictor*: loaders, preprocessing, encoders / imputers / scalers, feature steps, composition objects (`Pipeline`, `ColumnTransformer`, skrub `tabular_pipeline`, `nn.Module`), or the final estimator. - A pure-Python data-processing function destined for the pipeline path (cleans / derives / reshapes) — whether wrapped via `FunctionTransformer`, `skrub.@deferred` / `skrub.var`, a custom `BaseEstimator` subclass, or just called in the training path before the estimator. - A step is added, removed, swapped, or reordered inside an existing pipel

Build ML Pipeline (Declaration)

Declarative shape of a Python ML pipeline from data source to predictor.

Terms used in this skill

Read these once; they're referenced throughout.

  • X marker — the .skb.mark_as_X() call that anchors the predict-time slice. Everything upstream runs identically at fit and predict; everything downstream is per-prediction work.
  • Predict grid — the rows you want predictions for at predict time. For IID flat tables: the loaded frame itself. For time-series / panels: a (group, time) set.
  • Cold-start row — a predict-grid row that has no in-slice history available (typical for lags at the start of the slice).
  • Predict-time replay — re-binding the graph to a fresh source identifier at predict (e.g. learner.predict({"data_dir": …})).
  • Cross-row step — a feature whose output for a row reads values from other rows (lag, rolling window, group aggregation, side-table join by time/group, drop_nulls on a shifted column).
  • Layers 1 / 2 / 3 — source / predict-grid + X-marker / features after the marker. Defined in Rule 2.

Next-step pointers — where you go after this skill

You came here for…→ next
Declared pipeline → CV strategy→ evaluate-ml-pipeline (the G-CV-SPLITTER gate, rule 3)
Declared pipeline → smoke test→ test-ml-pipeline → smoke-test-ml-pipeline
Symbol lookup mid-declaration→ python-api (Shape 1 / 1b / 3)
Missing skrub/sklearn import→ python-env-manager § install
Modified pipeline.py / features.py / data.py→ python-code-style (ruff + NumPyDoc)

Always re-emit the Pre-flight checklist with evidence before declaring the turn done.

Canonical pipeline shape — IID flat-table

The 90% case. Copy + adapt; replace TARGET_COL and the regressor.

import skrub
from sklearn.ensemble import HistGradientBoostingRegressor

from <pkg>.data import TARGET_COL, load_raw


def build_learner(data_dir_preview=None):
    """Return the unfit learner (skrub SkrubLearner)."""
    data_dir = (
        skrub.var("data_dir", value=str(data_dir_preview))
        if data_dir_preview is not None
        else skrub.var("data_dir")
    )

    # Layer 1 + 2: load + mark X / y on the source frame.
    # No cross-row feature steps → marker sits here.
    data = data_dir.skb.apply_func(load_raw)
    X = data.drop(columns=[TARGET_COL]).skb.mark_as_X()
    y = data[TARGET_COL].skb.mark_as_y()

    # Layer 3: estimator at the tail. Feature engineering (if any)
    # chains between mark_as_X and the final .skb.apply.
    predictions = X.skb.apply(
        HistGradientBoostingRegressor(random_state=0), y=y
    )
    return predictions.skb.make_learner()

Stop conditions — read before anything else

Each Stop condition: rule → symptom → recovery. Scan top to bottom; any match means STOP.

S1. Missing dependency
  • Rule: import skrub raising means python-env-manager is next, not a substitute library.
  • Symptom: ModuleNotFoundError: No module named 'skrub'.
  • Recovery: invoke python-env-manager for the install command. Do NOT substitute with sklearn.Pipeline / make_pipeline / FunctionTransformer — that silently rewrites this skill out of the project.
S2. Symbol from memory is forbidden
  • Rule: every skrub / scikit-learn / skore name must come from a python-api lookup this turn.
  • Symptom: you type tabular_learner (renamed in 0.7+), mark_as_y(col) (signature dropped the positional in 0.9+), or any name "you remember".
  • Recovery: invoke python-api. Recognition is not a lookup; names drift between releases.
S3. Splitter selection is out of scope
  • Rule: no KFold / StratifiedKFold / train_test_split / any splitter import in pipeline code.
  • Symptom: you're about to type from sklearn.model_selection import KFold in pipeline.py.
  • Recovery: that's evaluate-ml-pipeline's territory. This skill only wires split_kwargs AT the X marker (see Rule 2).
S4. skrub.X(...) / skrub.y(...) are not acceptable graph roots
  • Rule: root on skrub.var("<source>", value=preview) instead.
  • Symptom: code starts with skrub.X(df) / skrub.y(s).
  • Recovery: rewrite to skrub.var("data_dir", value=...) → .skb.apply_func(load_fn) → .skb.mark_as_X(). The shortcuts (1) bake the marker at the source — defeating Layer 1; (2) force a pre-loaded binding, breaking predict-time replay; (3) silently re-enable the late-mark_as_X bug for cross-row features.
S5. Late mark_as_X is forbidden when any feature step is cross-row
  • Rule: for any cross-row step (lag, rolling, group-agg, target shift, side-join, drop_nulls on shifted col), the X marker goes UPSTREAM of that step. The step references the cross-row source as an additional apply_func argument (Layer 1 source → Layer 3 feature, via the marker bypass).
  • Symptom: the smoke test fails on len(predictions) != n_predict_grid_rows; OR a feature_steps=[] toggle appears in build_learner "to make predict work for cold-start"; OR a temp-dir gymnastic at predict time to fake history; OR a wrapper estimator whose only job is to filter NaN rows the pipeline itself produced. (Don't be misled by syntax — pl.col("x").shift(k) IS cross-row.)
  • Recovery: fix the graph topology via Rule 2's three-layer model. Don't loosen the smoke-test assertion. Don't wrap the predictor. Don't feature_steps=[].
  • Proof: smoke test (smoke-test-ml-pipeline) — pipeline with marker in the right place passes by construction.
S6. Layer 1 doesn't know the question
  • Rule: Layer 1 (sources + loaders) describes what data exists. Anything that requires knowing which rows we want predictions for — any horizon / lag / window / shift — belongs to Layer 2 or downstream, never Layer 1.
  • Symptom: the loader's body contains a target.shift(-HORIZON), a drop_nulls("y"), or any task-specific filter.
  • Recovery: push the task-specific operation past the marker into Layer 2 (target derivation via a stateful estimator) or Layer 3 (history-dependent feature). The smoke test passes trivially when the bug is fused into Layer 1 — CV looks fine, and the structural debt only surfaces when the next experiment composes against the raw source.
  • Constructive test: would an external consumer — a SQL view, a feature store, a second model — derive this same output without knowing your task? No → push it past the marker.
S7. All Python execution goes to scratch/
  • Rule: every Python command (version check, signature lookup, data inspection, loader sanity-check, anything) lands in scratch/<YYYY-MM-DD>_<HHMMSS>_<short>.py and runs via pixi run python scratch/<ts>_<short>.py.
  • Symptom: you catch yourself typing pixi run python -c or python -c.
  • Recovery: write the file first, then execute. Inline is forbidden regardless of length (see python-api § Stop conditions). No 2-line carve-out.
S8. Don't filter warnings
  • Rule: no warnings.filterwarnings(...) in pipeline.py or scratch probes unless the user explicitly asks. See python-code-style § Stop conditions.

## Stop conditions — read before anything else

Each Stop condition: **rule → symptom → recovery**. Scan top to
bottom; any match means STOP.

### S1. Missing dependency

- **Rule:** `import skrub` raising means `python-env-manager` is
  next, not a substitute library.
- **Symptom:** `ModuleNotFoundError: No module named 'skrub'`.
- **Recovery:** invoke `python-env-manager` for the install
  command. Do NOT substitute with `sklearn.Pipeline` /
  `make_pipeline` / `FunctionTransformer` — that silently rewrites
  this skill out of the project.

### S2. Symbol from memory is forbidden

- **Rule:** every skrub / scikit-learn / skore name must come from
  a `python-api` lookup *this turn*.
- **Symptom:** you type `tabular_learner` (renamed in 0.7+),
  `mark_as_y(col)` (signature dropped the positional in 0.9+), or
  any name "you remember".
- **Recovery:** invoke `python-api`. Recognition is not a lookup;
  names drift between releases.

### S3. Splitter selection is out of scope

- **Rule:** no `KFold` / `StratifiedKFold` / `train_test_split` /
  any splitter import in pipeline code.
- **Symptom:** you're about to type `from sklearn.model_selection
  import KFold` in `pipeline.py`.
- **Recovery:** that's `evaluate-ml-pipeline`'s territory. This
  skill only wires `split_kwargs` AT the X marker (see Rule 2).

### S4. `skrub.X(...)` / `skrub.y(...)` are not acceptable graph roots

- **Rule:** root on `skrub.var("<source>", value=preview)` instead.
- **Symptom:** code starts with `skrub.X(df)` / `skrub.y(s)`.
- **Recovery:** rewrite to `skrub.var("data_dir", value=...)` →
  `.skb.apply_func(load_fn)` → `.skb.mark_as_X()`. The shortcuts
  (1) bake the marker at the source — defeating Layer 1; (2)
  force a pre-loaded binding, breaking predict-time replay;
  (3) silently re-enable the late-`mark_as_X` bug for cross-row
  features.

### S5. Late `mark_as_X` is forbidden when any feature step is cross-row

- **Rule:** for any cross-row step (lag, rolling, group-agg,
  target shift, side-join, `drop_nulls` on shifted col), the
  X marker goes UPSTREAM of that step. The step references the
  cross-row source as an additional `apply_func` argument
  (Layer 1 source → Layer 3 feature, via the marker bypass).
- **Symptom:** the smoke test fails on `len(predictions) !=
  n_predict_grid_rows`; OR a `feature_steps=[]` toggle appears
  in `build_learner` "to make predict work for cold-start"; OR
  a temp-dir gymnastic at predict time to fake history; OR a
  wrapper estimator whose only job is to filter NaN rows the
  pipeline itself produced. (Don't be misled by syntax —
  `pl.col("x").shift(k)` IS cross-row.)
- **Recovery:** fix the graph topology via Rule 2's three-layer
  model. Don't loosen the smoke-test assertion. Don't wrap the
  predictor. Don't `feature_steps=[]`.
- **Proof:** smoke test (`smoke-test-ml-pipeline`) — pipeline
  with marker in the right place passes by construction.

### S6. Layer 1 doesn't know the question

- **Rule:** Layer 1 (sources + loaders) describes *what data
  exists*. Anything that requires knowing *which rows we want
  predictions for* — any horizon / lag / window / shift — belongs
  to Layer 2 or downstream, never Layer 1.
- **Symptom:** the loader's body contains a `target.shift(-HORIZON)`,
  a `drop_nulls("y")`, or any task-specific filter.
- **Recovery:** push the task-specific operation past the marker
  into Layer 2 (target derivation via a stateful estimator) or
  Layer 3 (history-dependent feature). The smoke test passes
  trivially when the bug is fused into Layer 1 — CV looks fine,
  and the structural debt only surfaces when the *next*
  experiment composes against the raw source.
- **Constructive test:** *would an external consumer — a SQL
  view, a feature store, a second model — derive this same
  output without knowing your task?* No → push it past the
  marker.

### S7. All Python execution goes to `scratch/`

- **Rule:** every Python command (version check, signature
  lookup, data inspection, loader sanity-check, anything) lands
  in `scratch/<YYYY-MM-DD>_<HHMMSS>_<short>.py` and runs via
  `pixi run python scratch/<ts>_<short>.py`.
- **Symptom:** you catch yourself typing `pixi run python -c`
  or `python -c`.
- **Recovery:** write the file first, then execute. **Inline is
  forbidden regardless of length** (see `python-api` § Stop
  conditions). No 2-line carve-out.

### S8. Don't filter warnings

- **Rule:** no `warnings.filterwarnings(...)` in `pipeline.py` or
  scratch probes unless the user explicitly asks. See
  `python-code-style` § Stop conditions.
