DeepSeek Harness Plugin

seally-web/dsh-matlab-runner

Category Development & Runtime Added 2026-10-31

MATLAB in the sidebar: a VS Code-like .m editor backed by a persistent MATLAB session (first boot ~6–9 s, then 12–84 ms per run in the default session mode, where figures really open on the desktop), live workspace variables you can edit, .mlx preview, extra folder mounts, and an agent-facing matlab_run tool. Requires a local MATLAB installation.

Install

# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)

dsh plugin --profile web add github:seally-web/dsh-matlab-runner

Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).
