Tianyi Cui 7a11f5fde3 docs(python): define the standalone minimal profile

Record sdk-minimal as the narrow repository-owned exception to base-first profile composition: callers still launch only dsh and cannot provide an arbitrary Cordis tree, while the shipped bundle may own a complete explicit roster. Cross-link the launcher, profile-bundle, Python-runtime, minimal-agent, snapshot, and telemetry decisions; the supersession audit keeps each older note active because its remaining rationale is independent.

Update the CLI, architecture, Python tutorial/reference, example, runtime-wheel reference, and bundle documentation. The docs distinguish the full sdk profile from sdk-minimal, explain explicit-home/plugin/patch customization, state the minimal permission and persistence choices, and retain the separately packaged web profile and frontend assets for direct dsh use.

Correct dsh-base descriptions to cover base-backed profiles, make SDK startup configuration visible in the generated config catalog, add sdk-minimal to the module graph, and regenerate the base-composition graph. English and Chinese pairs are re-recorded at the exact reviewed contents.

Python contributor workflows

English | 中文

Follow the workflow for the contributor outcome you need: build runtime artifacts, validate the SDK, run against source, or build distributions. Package behavior belongs in the SDK reference and runtime carrier reference.

Build runtime artifacts

Platform executables are build artifacts and are not checked into git. Run the build from the repository root:

pnpm install
pnpm exec tsx scripts/build-exe-for-python-sdk.ts

Use --skip-build when the required lib/ artifacts already exist, or --targets=node24-linux-x64,node24-linux-arm64,node24-macos-arm64 to select platforms. Products land in dist-exe/ and the script syncs the selected carriers into python/sdk-runtime/. macOS builds also sync the matching spawn helper required by node-pty.

Validate the SDK

Keep the virtual environment outside python/, install the test group, and run the Python suite:

export UV_PROJECT_ENVIRONMENT="$PWD/tmp/py-sdk-venv"
uv sync --project python/sdk --group test
uv run --project python/sdk pytest

python/sdk/tests/test_bundled_runtime.py exercises available bundled carriers and skips a carrier when its artifact has not been built. For repository-wide test policy, see Testing.

That suite drives fake runtime peers. scripts/smoke-python-runtime.py drives the packaged runtime instead. The required python-runtime CI job builds every published native target, installs the matching SDK and runtime wheels into a new Python 3.10 virtual environment, runs outside the checkout with PYTHONPATH and DSH_RUNTIME_MODE unset, proves that both modules and the executable came from those distributions, and then runs every keyless scenario. A focused local source-SDK run can select one built executable and scenario:

uv run --project python/sdk python scripts/smoke-python-runtime.py \
  --scenario sdk-minimal --exe dist-exe/deepseek-harness-sdk-runtime-macos-arm64

Three scenarios compare committed expected output under scripts/snapshots/python-sdk-single-exe/. minimal/model-visible.json pins the shipped sdk-minimal profile's assembled system prompts, advertised tool schemas, and model-visible messages, so a plugin that contributes an unintended system section or user message fails the job. advanced/ pins one complex process's SDK result and parent/child session logs. restart/ launches two complete SDK runtime processes against one persistence root and snapshots their isolated model histories, high-level results, and separate durable logs. Rerun the owning scenario with --update-snapshots and review that diff before committing it.

Trusted pull requests also run --scenario sdk-live --installed-wheel on every native target. That scenario performs two tool-using turns against https://api.deepseek.com, verifies the created file externally, and fails when the repository secret is absent instead of self-skipping. Fork and Dependabot pull requests run the complete keyless installed-wheel path but receive no key.

An interactive smoke test needs DEEPSEEK_API_KEY in the environment or repository-root .env:

from deepseek_harness import DeepSeekHarness

with DeepSeekHarness(dsh_home="/absolute/path/to/test-dsh-home") as harness:
    print(harness.run("say hi").final_response)

Alternatively export a non-empty DSH_HOME. The SDK rejects a launch that would silently use ~/.dsh.

Run against Node source

Repository contributors can select either development route; both execute the normal dsh --profile sdk launcher:

Set DSH_RUNTIME_MODE=node to use the built Node carrier on system Node >=22.19. The build script refreshes this carrier, but distributions never include or auto-select it.
Set dsh_bin to the absolute built apps/cli/lib/bin.js path to exercise the checkout's CLI directly. Supply an explicit dsh_home, plus profile and ordered patches as needed.

python/sdk/tests/manual_sdk_agent_smoke.py uses the internal _launch_args test adapter to exercise the unbuilt TypeScript CLI under tsx. Arbitrary argv replacement is intentionally absent from the public SDK.

Build distributions

The root package.json version is authoritative for both Python distributions. The staging script injects that version into both wheels and pins the SDK to the same deepseek-harness-runtime-bin version.

Build the pure SDK wheel once and one runtime wheel on each native platform:

version="$(python - <<'PY'
import runpy

release = runpy.run_path("scripts/build-python-release.py")
print(release["pep440_version"](release["repository_version"]()))
PY
)"
python scripts/build-python-release.py --package sdk --output-dir dist-python
python scripts/build-python-release.py --package runtime --platform macos-arm64 --runtime-exe dist-exe/deepseek-harness-sdk-runtime-macos-arm64 --output-dir dist-python
pip install \
  "dist-python/deepseek_harness_sdk-$version-py3-none-any.whl" \
  "dist-python/deepseek_harness_runtime_bin-$version-py3-none-macosx_14_0_arm64.whl"

The runtime distribution is wheel-only. The release pipeline publishes three platform wheels with the pure SDK wheel: Linux x64, Linux arm64, and macOS 14 or newer on arm64. A python-v<repository-version> tag is accepted only when it matches the repository version; prerelease repository versions such as 0.0.1-rc.1 use their normalized PEP 440 spelling, such as 0.0.1rc1, inside wheel filenames and metadata.

Validate a release candidate

Manually run the GitHub Release (Python) workflow with publish=false to build all four wheels, install the Linux release set on Python 3.10 and 3.14, check exact filenames and metadata, enforce PyPI's default per-file size limit, and retain one aggregate artifact with SHA-256 hashes. The run has no registry credentials; a dry run cannot enter either publication job.

Public publication runs from the private automation repository; package metadata points to the separate read-only public source mirror, which does not run release Actions. The private repository defines the repository variable PYPI_PUBLISHER_REPOSITORY as its own owner/name and keeps PUBLIC_PYPI_RELEASE_ENABLED=false except during an intentional release.

Separate runtime and SDK jobs let an SDK upload failure resume without resending immutable runtime files. They accept publish=true only when the workflow runs from the configured publisher repository at the matching python-v* tag and the protected pypi-runtime and pypi environments approve the runtime and SDK jobs, respectively. PyPI Trusted Publishing still supplies short-lived OIDC credentials, but public attestations are disabled because they would disclose the private publisher identity.
