What it does

Workflow JSON Builder is an agent skill from chengrouter/chengos. 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.

Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering REST APIs. The repository describes itself as: ChengOS is a visual AI data processing and agent workflow system. This directory contains deployment scripts, infrastructure configs, and runtime resources for production and…

Workflow steps

5 steps, taken from the step headings in SKILL.md.

Analyze node wiring for the user
Create workflow JSON from natural language
Configure or switch LLM models
Generate from templates
Explain workflows and node capabilities

What it can do on your machine

Read from SKILL.md and the folder at commit 3311be1. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Workflow JSON Builder loads about 3.2k tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 1,531 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~66
When it runs · the whole SKILL.md, loaded when a task matches: ~3.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,531 words (~3,229 tokens).

“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.”
