AskUserQuestion: single pick — the manager. Options from the

G-ENV-SCOPE — only for ambiguous extrasFires when: a requested dep doesn't match the § "Auto-routing
table" below (e.g. optuna, xgboost, mlflow).
AskUserQuestion (binary):
default — fold into runtime deps. Pick when the dep IS a
runtime concern.<X> — propose a name from the user's
wording (tracing for mlflow, tuning for optuna, dl for
torch). Pick when the dep is a tier-shift to feature-flag.Free-text resolution: explicit default or a feature name resolves;
"you pick" / "doesn't matter" does NOT.

files, or explore-ml-data for data/eda.py) needs ipython /
pyright and the manifest doesn't expose them. With explore-ml-data
this can fire as early as bootstrap (the G-EDA run path, before
the baseline), not only at the first audit.

# Python Env Manager
Detect the env manager, install with the right command. Single
authority for `data-science-python-stack` and the workflow skills
when they need a dependency added.
## Next-step pointers — where you go after this skill
| Came here from… | After install, next gate is… |
|---|---|
| `organize-ml-workspace` § scaffold | → `organize-ml-workspace` § Editable workspace package; continue scaffold |
| `audit-ml-pipeline` § agent-feature-missing | → return to `audit-ml-pipeline`; place `audit/<stem>.py` |
| `build-ml-pipeline` / `evaluate-ml-pipeline` § missing dep | → return to calling skill; continue at the failing pre-flight box |
| `data-science-python-stack` § Missing dependency | → return to caller; the import that was missing should now succeed |
Always re-emit the Pre-flight checklist with evidence before
declaring the turn done.
## Stop conditions — read before anything else
- **Wrong-manager install is forbidden.** If the project uses pixi,
do not `pip install`. If it uses poetry, do not `uv add`. Mixing
managers creates state the manifest doesn't track, and the next
`pixi install` / `poetry install` / `uv sync` silently undoes the
install.
- **No silent bootstrap.** If detection finds no manager, ask the
user. Default *recommendation* is pixi, but the user must
approve.
- **Dependency routing is fixed, not asked.** The 3-feature layout
(`default` / `dev` / `agent`) is enforced. The agent does NOT ask
per-install. `G-ENV-SCOPE` fires **only** for ambiguous extras
(`optuna`, `xgboost`, `mlflow`, …).
- **Don't pin without reason.** Install unpinned by default. Pin
only on user request or known incompatibility.
- **Don't run the bootstrap installer yourself.** When pixi (or any
manager) is missing, surface the install command and let the user
run it. `curl | sh` is a system-level action.
- **Harness "no clarifying questions" hints do NOT waive
`AskUserQuestion` mandates.** The manager pick and the scope pick
are operating-contract gates, not clarifying questions.
- **Post-hoc audit — required before ending the turn.** Walk the
pre-flight, confirm every ticked box has its `Evidence:` line. A
successful install command is not proof; the audit is.
## Forbidden shortcuts
| Shortcut | Why it's wrong |
|---|---|
| `pixi` on PATH → run `pixi init` / `pixi add` directly | Detection on PATH is context, not a pick. G-ENV-MGR still fires when no `Workspace decisions` row exists |
| User said "install ruff" → fire G-ENV-SCOPE | Routing is fixed: `ruff` / `pytest` / `ipykernel` / `jupyterlab` → `dev`. Scope ask is forbidden for the three known buckets |
| User asked for `xgboost` → silently drop into `default` | Ambiguous extras require the binary `default` vs new-named-feature ask |
| Calling skill writes its own `pixi add --feature agent ...` | Install commands are owned by this skill. Calling skills **request**; this skill installs |
| Agent feature install → also register a Jupyter kernel | The in-process runner does NOT use a kernel; registering one creates an orphan kernelspec |

## Gates this skill owns
### `G-ENV-MGR` — which manager
**Fires when**: detection returned `(nothing detected)` AND project is
fresh; OR detection returned a single manager but no
`Workspace decisions` row for `env manager` exists yet.
**AskUserQuestion**: single pick — the manager. Options from the
detection table. Default *recommendation* on nothing-detected:
`pixi`. Free-text resolves only when it names a listed manager.
**Persists**: `env manager: <pick> — recorded: <date>` in
`journal/JOURNAL.md` Status `Workspace decisions`.
→ next: § "Install commands — by manager".
### `G-ENV-SCOPE` — only for ambiguous extras
**Fires when**: a requested dep doesn't match the § "Auto-routing
table" below (e.g. `optuna`, `xgboost`, `mlflow`).
**AskUserQuestion (binary)**:
1. **`default`** — fold into runtime deps. Pick when the dep IS a
runtime concern.
2. **New named feature `<X>`** — propose a name from the user's
wording (`tracing` for `mlflow`, `tuning` for `optuna`, `dl` for
`torch`). Pick when the dep is a tier-shift to feature-flag.
Free-text resolution: explicit `default` or a feature name resolves;
"you pick" / "doesn't matter" does NOT.
#### When `default` is picked
One step: `pixi add <pkg>` (no `--feature` flag → lands in
`default`).
→ next: return to caller skill.
#### When a new named feature `<X>` is picked — 6 steps, all required
**This is the load-bearing procedure smaller models forget.** Step
3 specifically is the one that silently breaks LSP integration.
1. **Install into the new feature**: `pixi add --feature <X> <pkg>`
(manager-equivalents: `uv add --group <X> <pkg>`,
`poetry add --group <X> <pkg>`).
2. **Confirm the feature block exists** in the manifest.
3. **APPEND `<X>` to the `lsp` env's features list** —
per-manager:
- **pixi**: edit `pixi.toml` `[environments]`,
`lsp = { features = [..., "<X>"], ... }`.
- **uv / poetry**: nothing extra (`--all-groups` / `--with` covers).
- **hatch / conda / pip+venv**: re-author the lsp env's dep list.
4. **Re-sync the lsp env**: pixi → `pixi install -e lsp`; uv →
`uv sync --all-groups`; poetry → `poetry install --with <X>`;
others → re-create.
5. **Update `JOURNAL.md`**: append `<X>` to the
`optional features:` row.
6. **Verify**: `bash .agents/skills/python-env-manager/scripts/verify_layout.sh`.
Exit 0 = consistent. Exit 1 = drift, with remediation lines.
Skipping step 3 or 4 → the package installs into `<X>` but pyright
doesn't index it because `lsp` doesn't compose `<X>`. User sees
"unresolved import" on legitimate code.
→ next: return to caller skill.
### `G-AGENT-FEATURE` — install ipython + pyright
**Fires when**: an agent-only consumer (`audit-ml-pipeline` for audit
files, or `explore-ml-data` for `data/eda.py`) needs `ipython` /
`pyright` and the manifest doesn't expose them. With `explore-ml-data`
this can fire as early as **bootstrap** (the G-EDA run path, before
the baseline), not only at the first audit.
