Discover the public API of any installed Python package, cache what matters, never trust training-data memory.
Three durable rules:
scratch/api/<lib>/<version>/<topic>.md so the
next agent doesn't repeat the probe.references/ ≠ workspace cache. Bundled refs are
durable workflow patterns; cache files are per-version extracts.| Came here for… | After lookup, next is… |
|---|---|
| Symbol signature for code about to be written | → continue caller's flow (e.g. build-ml-pipeline § next step) |
| "Which library / which entry?" | → continue with the picked symbol; cache lands |
| Bootstrap turn (first workspace) | → required minimum cache lands; see references/bootstrap_cache.md |
| Failure debugging (KeyError / AttributeError) | → see Stop condition "Lookup failure ≠ artifact missing" |
Pick the shape by question type before picking a tool. Wrong shape produces a wrong-looking cache file and burns a turn.
| The user's question is shaped like… | Shape |
|---|---|
"What's in scratch/api/<lib>/<version>/?" (always check first) | 0 cache hit |
| "Which entry point for <task>?" | Stack orientation below, then Shape 1 / 1b to confirm |
| "What's the signature of X?" / "What args does X take?" / "What's the return type?" | 1b LSP hover (fast) → fall through to 1 if hover is sparse |
| "What does X do?" / "Full docstring of X?" (need Parameters / Examples / See Also) | 1 symbol card (pydoc) |
| "What's in module Y?" (open-ended discovery) | 2 module surface |
"Search for symbols matching foo* across the env" | 2b LSP workspace symbol |
| "How does X work?" / "Which of A or B should I use?" | 3 narrative |
"What does X return when <arg> is <value>?" | 3 narrative |
| "What's the recommended pattern for …?" | 3 narrative |
Shape 3 is the right answer when the question depends on a
condition over an argument. help() carries a Returns
section but typically does not enumerate dispatch behaviour under
each argument value — that lives in narrative docs.
Shape 1b vs Shape 1. Pyright hover gives the type signature
(richer inferred return types than inspect.signature) + the first
paragraph of the docstring — fast, no Python execution. Pydoc gives
the full docstring with all sections — slower but authoritative.
Default escalation: 1b first for "what's the signature"; fall
through to 1 if hover is empty / one-liner.
Prerequisites for Shape 1b / 2b (LSP shapes). Pyright available
via opencode LSP AND pyrightconfig.json pointing at the lsp env.
If either is missing, LSP shapes are unavailable — use Shape 1 / 2
directly. The agent feature: installed row in JOURNAL.md
Status Workspace decisions is the precondition; see
python-env-manager § Agent feature.
inspect.signature, a
scratch/api/<lib>/<version>/ file, or a fresh WebFetch.
Recognition does not count. Sticky named cases — full list in
references/named_traps.md:
tabular_learner → tabular_pipeline in 0.7+.mark_as_y(target_column) → signature dropped the
positional arg in 0.9+; use .skb.select("...") before mark.Project.get(...) is by id, not user-facing key;
enumerate via project.summarize() first.Signature / help() sections must remain blank or marked
<pending probe execution>. Same rule for Shape 3: do not
paraphrase docs from memory; cache file holds verbatim extracts.<pkg>.__version__ before any
lookup. The version subfolder is the cache freshness key.scratch/api/<lib>/<version>/ before Shape 1 / 2 / 3.KeyError /
AttributeError on a registry-style API (project.get(key),
getattr(obj, name), dict[key]) is almost always the lookup
shape (id vs key, wrong accessor) — not a missing artifact.
Named instance: skore.Project.get(...) resolves by id, not
by user-facing key; project.summarize() enumerates
(key, id) pairs. Never substitute by re-creating the
artifact — that lands a duplicate row.scratch/<YYYY-MM-DD>_<HHMMSS>_<short>.py. No exceptions.
Every Python command — pixi run python -c, python -c,
heredoc-style python << 'EOF', or any inline Python — is
forbidden, regardless of length. Write to scratch first, then
execute via pixi run python scratch/<ts>_<short>.py. Applies
to version checks, import smokes, signature lookups, module
surface dumps, docstring extraction, anything. If you catch
yourself typing python -c — STOP and write the file.| Shortcut | Why it's wrong |
|---|---|
| Recognise the symbol name from training data → write the call | Memory keyed to arbitrary version; install may have renamed / re-signatured |
| Probe ran, answer on screen → stop without writing the cache | Probe is investigation; cache is conclusion. Next session repeats the probe |
Bundled references/X.md exists → treat as the cache | References are workflow patterns; cache is per-version extracts. Both must exist |
| Version subfolder missing → write into the latest existing one | Subfolder is the freshness key. Create the right one |
Multi-symbol → string several inspect.signature into one inline python -c | All Python execution goes to scratch — no inline -c allowance. Multi-symbol → one scratch file → one consolidated cache file |
Used python -c "import <pkg>; print(<pkg>.__version__)" for a quick version check | Rule is unconditional. Length is not the criterion — traceability is. Version checks go to scratch/<ts>_version_<pkg>.py |
Cache exists for the topic; ran inline inspect.signature(X) to re-confirm one arg name | No inline single-signature carve-out exists. Every Shape 1 lookup uses the probe template |
Used python -c "...inspect.signature..." instead of writing the Shape 1 probe | Probe records the investigation; cache records the conclusion. Next session needs the file, not your transcript |
| User pasted a docs URL → treat as the answer | Lookup still requires inspect or WebFetch + cache write. URLs are leads |
Use __doc__ instead of pydoc.render_doc | __doc__ is empty on many accessors; cache file must be readable standalone |

# python-api
Discover the public API of any installed Python package, cache what
matters, never trust training-data memory.
Three durable rules:
1. **Lookup against the installed version, never memory.**
Recognition is not a lookup. The version may have renamed /
re-signatured / deprecated the symbol you remember.
2. **Cache to `scratch/api/<lib>/<version>/<topic>.md`** so the
next agent doesn't repeat the probe.
3. **Bundled `references/` ≠ workspace cache.** Bundled refs are
durable workflow patterns; cache files are per-version extracts.
## Next-step pointers
| Came here for… | After lookup, next is… |
|---|---|
| Symbol signature for code about to be written | → continue caller's flow (e.g. `build-ml-pipeline` § next step) |
| "Which library / which entry?" | → continue with the picked symbol; cache lands |
| Bootstrap turn (first workspace) | → required minimum cache lands; see `references/bootstrap_cache.md` |
| Failure debugging (KeyError / AttributeError) | → see Stop condition "Lookup failure ≠ artifact missing" |
## What kind of question? → Shape
Pick the shape **by question type** before picking a tool. Wrong
shape produces a wrong-looking cache file and burns a turn.
| The user's question is shaped like… | Shape |
|---|---|
| "What's in `scratch/api/<lib>/<version>/`?" (always check first) | **0** cache hit |
| "Which entry point for <task>?" | **Stack orientation** below, then Shape 1 / 1b to confirm |
| "What's the signature of X?" / "What args does X take?" / "What's the return type?" | **1b** LSP hover (fast) → fall through to **1** if hover is sparse |
| "What does X do?" / "Full docstring of X?" (need Parameters / Examples / See Also) | **1** symbol card (pydoc) |
| "What's in module Y?" (open-ended discovery) | **2** module surface |
| "Search for symbols matching `foo*` across the env" | **2b** LSP workspace symbol |
| "How does X work?" / "Which of A or B should I use?" | **3** narrative |
| **"What does X return when `<arg>` is `<value>`?"** | **3** narrative |
| "What's the recommended pattern for …?" | **3** narrative |
**Shape 3 is the right answer when the question depends on a
*condition* over an argument.** `help()` carries a `Returns`
section but typically does not enumerate dispatch behaviour under
each argument value — that lives in narrative docs.
**Shape 1b vs Shape 1.** Pyright hover gives the type signature
(richer inferred return types than `inspect.signature`) + the first
paragraph of the docstring — fast, no Python execution. Pydoc gives
the **full** docstring with all sections — slower but authoritative.
Default escalation: 1b first for "what's the signature"; fall
through to 1 if hover is empty / one-liner.
**Prerequisites for Shape 1b / 2b (LSP shapes).** Pyright available
via opencode LSP AND `pyrightconfig.json` pointing at the `lsp` env.
If either is missing, LSP shapes are unavailable — use Shape 1 / 2
directly. The `agent feature: installed` row in `JOURNAL.md`
Status `Workspace decisions` is the precondition; see
`python-env-manager` § Agent feature.
## Stop conditions — read before any lookup
- **No symbols from memory.** Every function / class / method / arg
must come from a lookup *this turn* — `inspect.signature`, a
`scratch/api/<lib>/<version>/` file, or a fresh WebFetch.
Recognition does not count. Sticky named cases — full list in
`references/named_traps.md`:
- skrub: `tabular_learner` → `tabular_pipeline` in 0.7+.
- skrub: `mark_as_y(target_column)` → signature dropped the
positional arg in 0.9+; use `.skb.select("...")` before mark.
- skore: `Project.get(...)` is by **id**, not user-facing `key`;
enumerate via `project.summarize()` first.
- **Never fabricate a probe result.** If the probe hasn't executed,
the `Signature` / `help()` sections must remain blank or marked
`<pending probe execution>`. Same rule for Shape 3: do not
paraphrase docs from memory; cache file holds verbatim extracts.
- **Version-correct first.** Resolve `<pkg>.__version__` before any
lookup. The version subfolder is the cache freshness key.
- **Cache hit before fresh fetch.** List
`scratch/api/<lib>/<version>/` before Shape 1 / 2 / 3.
- **Lookup failure ≠ artifact missing.** A `KeyError` /
`AttributeError` on a registry-style API (`project.get(key)`,
`getattr(obj, name)`, `dict[key]`) is almost always the **lookup
shape** (id vs key, wrong accessor) — not a missing artifact.
Named instance: `skore.Project.get(...)` resolves by **id**, not
by user-facing `key`; `project.summarize()` enumerates
`(key, id)` pairs. **Never substitute by re-creating the
artifact** — that lands a duplicate row.
- **All Python execution goes to
`scratch/<YYYY-MM-DD>_<HHMMSS>_<short>.py`. No exceptions.**
Every Python command — `pixi run python -c`, `python -c`,
heredoc-style `python << 'EOF'`, or any inline Python — is
forbidden, regardless of length. Write to scratch first, then
execute via `pixi run python scratch/<ts>_<short>.py`. Applies
to version checks, import smokes, signature lookups, module
surface dumps, docstring extraction, anything. If you catch
yourself typing `python -c` — STOP and write the file.
- **`inspect.signature` / `dir(...)` / `pydoc.render_doc` /
`help(...)` executed inline is NOT a python-api consultation.**
These are the exact APIs this skill wraps. Running them via
`python -c` does NOT satisfy the "python-api consulted"
pre-flight row in sibling skills. The deliverable is a
`scratch/api/<lib>/<version>/<topic>.md` file written this turn.
- **`pydoc.render_doc`, not `__doc__`.** `__doc__` is empty /
misleading on properties, descriptors, decorated callables, and
accessors — exactly the cases the cache disambiguates.
- **Narrative findings get cached.** A WebFetch result read and
discarded is forbidden. Land it in
`scratch/api/<lib>/<version>/<topic>.md` with the source URL on
the first line.
- **A probe without a cache write is not a completed lookup.**
Probe records the *investigation*; cache file records the
*conclusion*. Turn end without
`scratch/api/<lib>/<version>/<topic>.md` on disk = incomplete.
## Forbidden shortcuts
| Shortcut | Why it's wrong |
|---|---|
| Recognise the symbol name from training data → write the call | Memory keyed to arbitrary version; install may have renamed / re-signatured |
| Probe ran, answer on screen → stop without writing the cache | Probe is investigation; cache is conclusion. Next session repeats the probe |
| Bundled `references/X.md` exists → treat as the cache | References are workflow patterns; cache is per-version extracts. Both must exist |
| Version subfolder missing → write into the latest existing one | Subfolder is the freshness key. Create the right one |
| Multi-symbol → string several `inspect.signature` into one inline `python -c` | All Python execution goes to scratch — no inline `-c` allowance. Multi-symbol → one scratch file → one consolidated cache file |
| Used `python -c "import <pkg>; print(<pkg>.__version__)"` for a quick version check | Rule is unconditional. Length is not the criterion — traceability is. Version checks go to `scratch/<ts>_version_<pkg>.py` |

| Use `__doc__` instead of `pydoc.render_doc` | `__doc__` is empty on many accessors; cache file must be readable standalone |
## First action — every turn that triggers this skill
1. **Resolve the version.** Write
`scratch/<YYYY-MM-DD>_<HHMMSS>_version_<pkg>.py` with
`import <pkg>; print(<pkg>.__version__)`, run via
`pixi run python scratch/<ts>_version_<pkg>.py`. **No inline
`python -c`.**
2. **List the cache:** `ls scratch/api/<lib>/<version>/`.
3. **Cache hit?** Read the matching file. Done.
4. **Cache miss?** Classify the question (table above) → run Shape
1 / 1b / 2 / 2b / 3.
5. **Emit the pre-flight checklist** with each box marked.
## Pre-flight — emit before any lookup

Skill purpose: Look up the public API of a Python package against the *installed version* and cache what's worth keeping.

Never write a symbol from training-data memory — recognition is not a lookup. TRIGGER — any of: - About to name a symbol (function / class / method / arg) in code. - User asks \"what's the signature of X?\", \"what's in module Y?\", \"how do I call X?\", \"which of A/B should I use?\". - User asks \"what does X return when <condition>?\" (Shape 3 — see decision table). - Another workflow skill (`build-ml-pipeline`, `evaluate-ml-pipeline`, `iterate-from-skore`, `smoke-test-ml-pipeline`) says \"consult the API skill\". - About to reach for a library's \"obvious\" pattern from memory.
