Use this skill when the online UI chat assistant must guide a user through designing a ChengOS workflow and generate an importable workflow JSON file. The assistant uses Workflow API endpoints for templates, node schemas, and LLM model lists.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Workflow JSON Builder Use this skill in the online UI chat dialog when the goal is to help the user design a workflow and produce a JSON artifact they can import into the workflow editor. The assistant calls the separately deployed Workflow API to gather context, then returns workflow JSON to the user. > **Authoritative contract:** all generated workflow JSON must follow the > **Workflow JSON Contract** (`docs/workflow-json-generation-guide.md`) — the > single source of truth for structure, field names, port handling, and > `skipValidation` semantics. This skill is the UI-chat front end to that > contract; when in doubt, defer to the contract. > > **Scope & contract boundary:** this skill targets the **UI/REST API DTO** path > (the endpoints below), which is distinct from the canonical **file-import** > contract (`workflow.json` = `WorkflowFileV1`: camelCase, required top-level > `name`, nested `definition`). `skipValidation` affects only this API/DTO path, > **not** the file importer. Use the same field names (`nodeId`, `nodeType`, > `sourceNode`/`sourcePort`/`targetNode`/`targetPort`) and identity rules (all …

How to install
mdr add chengrouter/chengos/workflow-json-builder@sha256:e9b4c27830327760The line at the top of this page pins the label git:20260725.902055e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
