 All notable changes to the `toolchain` plugin are documented here. Format follows
 [Keep a Changelog](https://keepachangelog.com/en/1.1.0/); this plugin uses semantic versioning.
 
+## [0.7.0]
+
+### Added
+
+- **`pyright` added to the bundled Python ecosystem default's `check-cmd`.** Local `/toolchain:check`
+  now runs `uv run pyright` alongside the existing ruff lint/format check, closing the gap where CI
+  gated pyright but the local batch was ruff-only. Rung-4 fallback only — a consumer's own
+  `.claude/ecosystems/python.yaml` overrides `check-cmd` key-by-key and is unaffected. `fix-cmd` is
+  unchanged (pyright has no fix mode). `context/python.md` documents the default standard-mode gotcha
+  for untyped projects.
+
 ## [0.6.0]

 - **Use `uv run` prefix in uv-managed projects** (a `uv.lock` is the signal) — it ensures the managed virtualenv is used. In pip/poetry projects, use that project's documented invocation instead
 - **E501 (line-too-long) is not auto-fixable** — the formatter handles code wrapping, but docstrings/comments/string literals exceeding the configured `line-length` must be shortened manually
+- **pyright runs in its default standard mode absent a `pyrightconfig.json` or `pyproject.toml [tool.pyright]`** — on an untyped or partially-typed project this can surface genuine type errors; set `typeCheckingMode` (e.g. `basic` or `off`) or add project config to tune the strictness rather than suppressing findings ad hoc
 - **Run from project directory** — each `pyproject.toml` defines an independent project root. Always `cd` to the directory containing `pyproject.toml` before running commands
 - **`encoding='utf-8'`** — always specify on Windows `open()` calls
