-Repo-specific stack and runbooks will be added here with spec 001 (issue #1).
+## What this repo is
+
+The shared tooling of the `dataset-*` repos: the source toolkit (spec 004) and, next, the input contract with its reference builder and validator (spec 001). Specs: [`docs/specs/ROADMAP.md`](docs/specs/ROADMAP.md). Decisions: [`docs/adr/`](docs/adr/).
+
+## Stack
+
+Python 3.12, `uv`, `pytest`, built with `hatchling`. Distribution `benchcommons-tools-dataset`, import package `datasettool` ([ADR 0003](docs/adr/0003-python-package-name.md)). Runtime dependencies pinned: `pyyaml==6.0.3`, `xlrd==2.0.2` ([ADR 0005](docs/adr/0005-source-toolkit-runtime-dependencies.md)); a new one needs an ADR.
+
+## Commands
+
+```sh
+uv sync --locked      # install
+uv run pytest -q      # tests (never use the network; downloads go to a server on 127.0.0.1)
+```
+
+## Releases
+
+SemVer tags `vX.Y.Z` on `main`, created by the maintainer after merge, never moved. `version` in `pyproject.toml` equals the tag without `v`. Dataset repos pin a tag through `[tool.uv.sources]` ([ADR 0004](docs/adr/0004-dataset-repos-depend-on-a-git-tag.md)).
+
+## Conventions
+
+- Docs, specs, ADRs, code, comments and messages in English.
+- Conventional Commits; signed commits; AI co-authorship only as a `Co-Authored-By:` trailer.
+- Code ported from another repo names its origin (`ported from BenchCommons/<repo>@<sha> <path>`) in the commit message.
+- Open items go in issues, never in docs or code.

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+# 0003. Python package name: `benchcommons-tools-dataset`, imported as `datasettool`
+
+## Status
+
+Accepted (2026-10-12). Spec [004](../specs/004-source-toolkit/spec.md).
+
+## Context
+
+Spec 004 makes this repo an installable Python package, first for the source toolkit and later for the reference builder and validator of spec 001. Spec 001's plan already places the code in `src/datasettool/`. The package needs a distribution name (what `uv` and `pip` install) and an import name (what code imports).
+
+This repo was renamed from `dataset-tool` to `tools-dataset` by [.product ADR 0005](https://github.com/BenchCommons/.product/blob/main/docs/adr/0005-tools-prefix.md). A bare `tools-dataset` is generic enough that an unrelated project on PyPI may hold it, and a git dependency still declares a distribution name that must not collide with anything a dataset repo also installs. Import names cannot contain `-`.
+
+Where the toolkit lives (here rather than in `tools-commons`) is [ADR 0007](0007-source-toolkit-lives-in-tools-dataset.md).
+
+## Decision
+
+- Distribution name: **`benchcommons-tools-dataset`**: the org prefix plus the repo name, so a lock file shows where the code comes from.
+- Import package: **`datasettool`**, as in spec 001's plan, so the two specs share one package and no import changes with the repo rename.
+- Layout: the source toolkit lives in the subpackage `datasettool.sources` (`cache`, `spreadsheet`, `adapters`, `registry`); helpers shared with spec 001 (checksums, row counts) live at the top level (`datasettool.files`). Spec 001 adds its own modules next to them.
+- The command name of spec 001's CLI is decided by spec 001.
+
+## Consequences
+
+- Dataset repos write `benchcommons-tools-dataset` in their dependencies and `from datasettool.sources import cache` in code.
+- The distribution and import names differ, which is common in Python but must be documented in `AGENTS.md` and `README.md`.
+- Renaming later breaks every dataset repo's imports and lock file, so the names are fixed from `v0.1.0`.
