SymPy-Calculate

A third-party 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_calculate executes 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.

• Each call is bounded by a 120-second timeout; stdout and stderr are each capped at 2,000,000 characters.

The tool defaults to ~/sympy-dev/sympy and its venv:

sudo apt install -y python3-venv
mkdir -p ~/sympy-dev
git clone https://github.com/sympy/sympy.git ~/sympy-dev/sympy
python3 -m venv ~/sympy-dev/sympy/venv
~/sympy-dev/sympy/venv/bin/python -m pip install -e ~/sympy-dev/sympy

For a different checkout or interpreter, set SYMPY_ROOT / SYMPY_PYTHON before starting DSH.

Among shipped profiles, install into web only. The web bundle provides the agent-preset-registry service the preset needs. A custom profile can use the preset if that profile provides the service as well.

The easiest way is from the Web UI: go to Plugins → Add plugin, enter @e_11350613/dsh-sympy-calculate@1.0.6, choose Custom address under Registry, and enter https://registry.npmjs.org/. Then select Install. No GitHub URL or SSH key is needed.

Alternatively, from the CLI, install @e_11350613/dsh-sympy-calculate from npm into the web profile. If dsh is already on your PATH, replace the npx --yes @deepseek-ai/dsh@0.2.1-rc.2 prefix with dsh.

npx --yes @deepseek-ai/dsh@0.2.1-rc.2 plugin --profile web add \
  @e_11350613/dsh-sympy-calculate@1.0.6

npx --yes @deepseek-ai/dsh@0.2.1-rc.2 plugin --profile web add \
  https://codeload.github.com/11350613/SymPy-Calculate/tar.gz/v1.0.6

npx --yes @deepseek-ai/dsh@0.2.1-rc.2 plugin --profile web add \
  github:11350613/SymPy-Calculate#v1.0.6

pnpm dsh plugin --profile web add \
  @e_11350613/dsh-sympy-calculate@1.0.6

Start or restart the web profile. SymPy Calculate will then be available as an agent preset for new tasks.

Check the composed profile:

npx --yes @deepseek-ai/dsh@0.2.1-rc.2 --profile web --dump-config \
  | grep "SymPy Calculate"

In the Web UI, confirm that SymPy Calculate appears as an agent preset without a Failed to load badge.

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
