# Explore ML Data
Understand the dataset before designing a model. One project-level
EDA per workspace: an executable `data/eda.py`, a persisted
`data/eda.md` narrative, rich `data/eda_<table>.html` reports, and a
short JOURNAL section that links them. The findings feed the baseline
design note's learner / splitter / metric choices.
## Next-step pointers — where you go after this skill
| You came here for… | → next |
|---|---|
| Bootstrap, before the first baseline | → back to `iterate-ml-experiment` § 0; the EDA findings inform the auto-drafted `01_baseline.md` |
| User free-text ("explore the data") | → surface the findings; no further dispatch unless the user asks to model |
| Re-understand a changed data source | → re-run, overwrite `data/eda.*`, refresh the JOURNAL EDA section |
Always re-emit the Pre-flight checklist with evidence before
declaring the turn done.
## Where this sits in the loop
EDA is a **bootstrap-time gate (G-EDA)** owned by this skill and
fired by `iterate-ml-experiment` § 0 **before** the baseline design
note. Ordering matters: the dataset facts (class balance, datetime /
group columns, missingness, cardinality) are exactly what justifies
the splitter (`G-CV-SPLITTER`), the metric default, and the learner
default. Running EDA after the model is designed defeats the purpose.

## Where things live — visual map
Two locations are kept separate: the **raw data source** (read-only,
may live anywhere) and the **EDA deliverables** (always under
`<project>/data/`).
| Path | Durability | Who writes it | What it holds |
|---|---|---|---|
| raw data source (`data/`, `raw/`, an absolute path, external) | user-owned, **READ-ONLY** | the user | The dataset. EDA reads it; never modifies it. May be anywhere — not assumed to be `data/` |
| `data/eda.py` | **Durable** (committed) | This skill, once per workspace | The jupytext `# %%` EDA cells. Source of truth. Openable as a notebook for the rich view |
| `data/eda.md` | **Durable** (committed) | This skill (authored from the digest) | The prose narrative: findings + **modelling implications** that the baseline note cites |
| `data/eda_<table>.html` | **Durable** (committed) | `data/eda.py` via `TableReport.write_html(...)` | The rich, interactive skrub report per table — for the human |
| `scratch/eda/eda.md` | Ephemeral (gitignored), optional | `run_cells.py` when given a 2nd arg | Per-cell digest the agent reads. Same content as stdout |
| `journal/JOURNAL.md` § Data understanding (EDA) | **Durable** (committed) | This skill | 2–4 line summary + link to `data/eda.md` |
**Mnemonic:** the raw data is *read-only and lives wherever the user
keeps it*; `data/eda.py` is *source*; `data/eda.md` + the HTML are the
*durable deliverables, always under `data/`*; `scratch/eda/` and
stdout are the *ephemeral run digest*.
## Read-only-against-raw-data contract
The central rule. Surfaced as the first Stop condition below.
**Allowed — this skill writes ONLY (deliverables always under
`<project>/data/`, created if absent):**
- `data/eda.py` — the EDA script (created / overwritten in place).
- `data/eda.md` — the authored narrative.
- `data/eda_<table>.html` — the skrub `TableReport` pages.
- `scratch/eda/` — the ephemeral digest.
- `journal/JOURNAL.md` § Data understanding (EDA).
**Forbidden:**
- Modifying, deleting, renaming, re-encoding, or "cleaning" the
user's raw data files — **wherever they live** (`data/`, another
folder, an absolute/external path). EDA **reads** them; it never
rewrites them. Data cleaning is the pipeline's job
(`build-ml-pipeline`), declared at fit time, not a one-off mutation.
- Writing anywhere outside the five paths above — no `src/<pkg>/`
edits, no `reports/` writes, no new experiment files.
- Designing the model: no `skore.evaluate(...)`, no `project.put(...)`,
no learner selection here. EDA *informs* those; it does not make
them.
## Stop conditions — read before anything else
- **Read-only against the user's raw data.** See § Read-only-
against-raw-data contract. `data/eda.py` reads the raw files
(wherever they live) and writes only the `data/eda.*` deliverables.
- **Deliverables always under `<project>/data/`; the raw source is
separate.** Write `data/eda.py` / `data/eda.md` /
`data/eda_<table>.html` under `<project>/data/` (create the folder
if absent). The raw data the script *reads* may live anywhere
(`data/`, another in-repo folder, an absolute or external path) —
decouple the two: a `RAW = <LOAD_RAW_DATA>` source vs an `EDA_DIR`
output. Never assume the raw data is in `data/`.
- **EDA precedes model design (G-EDA).** In bootstrap, the gate fires
**before** `journal/01_baseline.md` is drafted. It is binary:
**run** (place + execute `data/eda.py`, write the deliverables) or
**skip** (record `Status: skipped — <date>` in the JOURNAL section
and proceed). Do not silently bypass — fire the `AskUserQuestion`.
Free-text "go fast" / "quick baseline" does NOT resolve it.
- **Agent feature required to execute.** The cell runner needs
`ipython`. If it is missing and the user chose **run**, STOP and
delegate to `python-env-manager` § "Agent feature"
(`G-AGENT-FEATURE`). Do NOT type `pixi add ... ipython` yourself;
do NOT fabricate EDA output with hand-written `print()`s. If the
user declines the agent feature, **fall back to the skip path**
(record `Status: skipped`) — never loop between run and install.
- **Symbol from memory is forbidden.** Any `skrub` / `pandas` /
`polars` symbol (`TableReport`, `TableReport.json`, `write_html`,
`column_associations`, the tabular reader, …) must come from
`python-api` *this turn*. Cache hits under
`scratch/api/<lib>/<version>/` count; inline memory does not.
**`TableReport.json()`'s key names are not formally documented and
drift across skrub versions — confirm them via `python-api` and
parse defensively (`.get(...)`).**
- **Library-agnostic — read facts off skrub, not pandas/polars.** The
workspace may use pandas OR polars (G-TABULAR), whose summary
methods differ (`select_dtypes` doesn't even exist in polars). The
structured facts come from `skrub` (`TableReport(...).json()`,
`column_associations`), which accept both. The ONLY library-
specific line is `RAW = <LOAD_RAW_DATA>`. Do not write
`df.isna()`/`df.nunique()`/`df.select_dtypes(...)` etc.
- **`skrub.TableReport` for dataframe overviews.** Every table gets a
`TableReport(RAW, title=..., verbose=0)` written to
`data/eda_<table>.html` (the user-facing artifact) AND read via
`.json()` for the digest. `verbose=0` keeps progress prints out of
the digest.
- **Never end a cell on a bare `TableReport`.** Outside a notebook,
`repr(TableReport(df))` is the useless `<TableReport: use .open()
to display>`. Use `report.write_html(...)` (a statement) for the
HTML, and end cells on **text-friendly** expressions (`RAW.shape`,
a `dict`/`list` built from `report.json()`,
`skrub.column_associations(RAW)`) so the digest carries real
values. Mirrors audit's `.frame()` rule.
- **Never gitignore the whole `data/`; ask about the inputs.** The
deliverables live in `data/` and must stay committable, so the
whole `data/` folder must never be in `.gitignore`. If the raw
inputs should be kept out of git (large / local-only), fire an
`AskUserQuestion` offering to ignore **specific input patterns**
(e.g. `data/raw/`, `data/*.parquet`) — default: don't. Then verify
the deliverables are tracked (`git check-ignore data/eda.md` must
return nothing). Never auto-edit `.gitignore` — that is
`organize-ml-workspace`'s to write; surface the patch and ask.
- **One project-level EDA.** A single `data/eda.py` covers the whole
dataset; multi-table data gets one `TableReport` cell per table
inside that one file (run the target/structure cells on the
target-bearing table). No `eda_v2.py`, no per-experiment EDA files,
not part of the four-way stem pairing. Re-understanding overwrites
`data/eda.py` in place.
- **Don't design the model here.** No splitter pick, no metric pick,
no learner pick. Record *implications* in `data/eda.md`; the picks
happen in their owning gates (`G-CV-SPLITTER`, the baseline note).
- **Harness "no clarifying questions" hints do NOT waive G-EDA or
G-AGENT-FEATURE.** Both fire regardless.
- **Post-hoc audit — required before ending the turn.** Walk every
pre-flight row; surface unfilled Evidence cells explicitly.

select_dtypesskrubTableReport(...).json()column_associationsRAW = <LOAD_RAW_DATA>df.isna()df.nunique()df.select_dtypes(...)skrub.TableReport for dataframe overviews. Every table gets a
TableReport(RAW, title=..., verbose=0) written to
data/eda_<table>.html (the user-facing artifact) AND read via
.json() for the digest. verbose=0 keeps progress prints out of
the digest.TableReport. Outside a notebook,
repr(TableReport(df)) is the useless <TableReport: use .open() to display>. Use report.write_html(...) (a statement) for the
HTML, and end cells on text-friendly expressions (RAW.shape,
a dict/list built from report.json(),
skrub.column_associations(RAW)) so the digest carries real
values. Mirrors audit's .frame() rule.data/; ask about the inputs. The
deliverables live in data/ and must stay committable, so the
whole data/ folder must never be in .gitignore. If the raw
inputs should be kept out of git (large / local-only), fire an
AskUserQuestion offering to ignore specific input patterns
(e.g. data/raw/, data/*.parquet) — default: don't. Then verify
the deliverables are tracked (git check-ignore data/eda.md must
return nothing). Never auto-edit .gitignore — that is
organize-ml-workspace's to write; surface the patch and ask.data/eda.py covers the whole
dataset; multi-table data gets one TableReport cell per table
inside that one file (run the target/structure cells on the
target-bearing table). No eda_v2.py, no per-experiment EDA files,
not part of the four-way stem pairing. Re-understanding overwrites
data/eda.py in place.data/eda.md; the picks
happen in their owning gates (G-CV-SPLITTER, the baseline note).Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
