Give the SDK JSON-RPC server a per-root tool filter and let deployments mark the configured persona as the complete system prompt. The checked-in minimal overlay now names only bash and str_replace_editor, so later global tools and unrelated guidance from dsh-base cannot appear implicitly. Keep the shared SDK host services and packaged Web capability intact. Only workspace instructions, compaction, and the conflicting one-shot Bash row remain disabled. Unit coverage pins the configuration paths, and a real dsh profile smoke proves the assembled prompt and exact two-tool request.

Runnable Python SDK example over the sole application launcher, dsh --profile sdk. The Python client owns JSON-RPC stdio; the profile owns the agent composition, persistence, permissions, and plugins.
Run the minimal agent
Install deepseek-harness-sdk, export a model credential, then supply an isolated Harness home and workspace:
export DEEPSEEK_API_KEY=sk-your-key-here
python examples/python-sdk-agent/minimal.py \
--dsh-home /absolute/path/to/example-dsh-home \
--workspace /absolute/path/to/disposable-workspace \
--session-id example-001 \
"Inspect the repository and fix the failing tests."
Set DEEPSEEK_BASE_URL for a compatible proxy, DSH_MODEL for the default model, or DSH_SYSTEM_PROMPT for the deployment persona. --model and --profile override their script defaults. The selected home stores the generated profile and Zstandard session logs under sessions/; the script never reads ~/.dsh implicitly.
minimal.patch.yml is an ordered overlay on the shipped SDK profile. Its root-agent tool allowlist exposes exactly:
- owner-scoped persistent
bash str_replace_editorwithview,create,str_replace, andinsert
The allowlist excludes every other current or later global tool without requiring a disable entry for each base row. A complete deployment persona suppresses unrelated tool-guidance sections; runtime-context messages, local instruction discovery, compaction, and the conflicting one-shot Bash row are disabled separately. The overlay inserts the local PTY and persistent Bash providers and sets the editor output limit to 16,000 characters. Other SDK-profile services remain mounted, including persistence, policy, settings, credentials, and providers.
This variant is intentionally POSIX-only. Its persistent PTY and editor can modify any path available to the runtime process, so use a disposable checkout or container.
Add plugins
Use the runtime wheel's dsh command against the same explicit home for persistent profile changes:
export DSH_HOME=/absolute/path/to/example-dsh-home
dsh plugin --profile sdk add file:/absolute/path/to/my-plugin-bundle
The Python call can also pass additional absolute patch paths in patches=(...); later files win. A selected profile must retain @deepseek-ai/dsh-sdk-app or another JSON-RPC server row. Complete standalone Cordis files in this directory remain test fixtures for lower-level composition coverage; they are not Python SDK launch interfaces.
