Visual drag-and-drop workflow builder for DSH — orchestrate tool calls, sub-agents, and conditional branches on a React Flow canvas.
Install
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:PiedPiper911/dsh-workflow-canvas
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).
README
Visual workflow builder for DeepSeek Harness (DSH).
Drag and drop nodes to orchestrate tool calls, sub-agents, and conditional branches into a workflow that runs through DSH's ctx.workflows engine. Powered by React Flow (xyflow) and Zustand.
Install
dsh plugin add @piedpiper911/dsh-workflow-canvas
Node types
| Node | What it does |
|---|---|
| ▶ Trigger | Workflow entry point (a prompt). |
| ⚙ Tool | A single tool call (e.g. video_frames, bash). |
| 🤖 Agent | Delegate a step to a sub-agent with its own prompt. |
| ◇ Condition | Branch on an expression (then/else edges). |
| ✓ Output | Terminal result template. |
How it works
- Build a graph on the canvas: drag nodes from the toolbar, connect them with edges.
- The store compiles the graph into an ordered step list (breadth-first from triggers, conditions become branches) — this is the exact shape DSH's workflow engine consumes.
Runhands the steps toctx.workflows;Exportsaves a.workflow.jsonyou can reload later.
The data model is deliberately transport-agnostic: the canvas is a view over a plain-JSON workflow spec, so it composes with any DSH workflow provider.
