A DeepSeek Harness agent preset based on minimal. It adds one stateless
tool, sympy_calculate, which runs a complete Python script in a fresh
process against a local SymPy development checkout.
Security:
sympy_calculateexecutes arbitrary Python with the current user's permissions and inherited environment. It is not sandboxed. Enable it only in sessions whose model and permission policy you trust.
minimal plane plus sympy_calculate.| Requirement | Version / notes |
|---|---|
| DeepSeek Harness | 0.2.0-rc.2 |
| Node.js | ^22.19.0 or >=24.0.0 |
| pnpm | 11.7.0; install with npm install -g pnpm@11.7.0 if missing |
| git | Needed for the SymPy checkout; optional for the HTTPS install |
| Python | 3.x with venv and pip available |
| SymPy | Local checkout; default root ~/sympy-dev/sympy |
| Platform | Tested on Ubuntu 24.04.4 LTS only; other platforms are untested |
Among shipped profiles, install into web only. The preset needs the
agent-preset-registry service supplied by the web bundle; in headless,
sdk, sdk-minimal, or acp it will not be selectable. A custom profile
can use it if that profile supplies agent-preset-registry.
The tool uses this checkout root and interpreter candidates:
~/sympy-dev/sympy
~/sympy-dev/sympy/venv/bin/python
~/sympy-dev/sympy/venv/bin/python3
On Ubuntu, install the venv tooling first if it is missing:
sudo apt install -y python3-venv python3-pip
Then create the checkout:
mkdir -p ~/sympy-dev
git clone https://github.com/sympy/sympy.git ~/sympy-dev/sympy
# Optional: use the exact tested SymPy revision.
git -C ~/sympy-dev/sympy checkout 6aabf6ac9eddd1c5141ff9a3a35dcb53a7b02228
python3 -m venv ~/sympy-dev/sympy/venv
~/sympy-dev/sympy/venv/bin/python -m pip install -e ~/sympy-dev/sympy
echo 'venv/' >> ~/sympy-dev/sympy/.git/info/exclude
The editable install also installs SymPy's external mpmath dependency.
Confirm the checkout before installing the plugin:
~/sympy-dev/sympy/venv/bin/python -c "import sympy; print(sympy.__version__)"
To use another checkout or interpreter, set both variables in the environment that starts DeepSeek Harness:
| Variable | Default | Meaning |
|---|---|---|
SYMPY_ROOT | ~/sympy-dev/sympy | Checkout root; also the PYTHONPATH |
SYMPY_PYTHON | <root>/venv/bin/python, then python3 | Python interpreter |
Install into the web profile. The commands pin v1.0.4, the tested
plugin revision. If dsh is already on your PATH, replace the
npx --yes @deepseek-ai/dsh@0.2.0-rc.2 prefix with dsh.
HTTPS tarball, recommended because it needs no GitHub SSH key:
npx --yes @deepseek-ai/dsh@0.2.0-rc.2 plugin --profile web add \
https://codeload.github.com/11350613/SymPy-Calculate/tar.gz/v1.0.4
Git shorthand, when GitHub SSH access is already configured:
npx --yes @deepseek-ai/dsh@0.2.0-rc.2 plugin --profile web add \
github:11350613/SymPy-Calculate#v1.0.4
From a source checkout, use pnpm dsh and prefer the tarball form:
pnpm dsh plugin --profile web add \
https://codeload.github.com/11350613/SymPy-Calculate/tar.gz/v1.0.4
Start or restart the web profile, then select SymPy Calculate when creating a session.
Check that the bundle and preset are in the composed config:
npx --yes @deepseek-ai/dsh@0.2.0-rc.2 --profile web --dump-config \
| grep "SymPy Calculate"
Boot the profile once without a browser to surface plugin activation
errors. Wait for the dsh web: http://127.0.0.1:<port>/?token=... line, then
stop it with Ctrl-C. A plugin activation failure exits non-zero and prints the
loader diagnostic:
npx --yes @deepseek-ai/dsh@0.2.0-rc.2 --profile web --no-open --port 0
Then start the UI and confirm that SymPy Calculate appears in the preset picker without an error marker:
npx --yes @deepseek-ai/dsh@0.2.0-rc.2 --profile web --no-open
In a session using the SymPy Calculate preset, ask:
Use sympy_calculate to compute $\int_{-\infty}^{\infty} \frac{x^2}{1 + x^4}\,\mathrm{d}x$.
sympy_calculate expects one complete script:
{
"code": "from sympy import *\n\nx = symbols('x')\nprint(integrate(x**2 / (1 + x**4), (x, -oo, oo)))\n"
}
Output:
sqrt(2)*pi/2
Because every call starts a fresh interpreter and pays the SymPy import cost, batch related computations into one script instead of making many small calls. stdout and stderr are combined; a non-zero exit is returned as a tool error.
| Symptom | Fix |
|---|---|
sympy_calculate: no Python interpreter under ... | Run the SymPy setup above, or export SYMPY_ROOT / SYMPY_PYTHON before starting dsh. |
python3 -m venv fails with ensurepip is not available | Install python3-venv; on Ubuntu 24.04 also install python3.12-venv. |
ModuleNotFoundError: No module named 'mpmath' | Install the checkout with pip install -e; a bare git clone has no dependencies. |
| The preset is missing after installing | Restart the web profile, and check that dsh-sympy-calculate is listed in the profile's package.json dependencies and dsh.profile.bundles. |
| The preset shows a broken/error marker | Boot the web profile with npx --yes @deepseek-ai/dsh@0.2.0-rc.2 --profile web --no-open --port 0 and read the loader diagnostic. The usual cause is installing into a profile without agent-preset-registry. |
| Remove the plugin | npx --yes @deepseek-ai/dsh@0.2.0-rc.2 plugin --profile web remove dsh-sympy-calculate |
