Workflow Run is an agent skill from ruvnet/ruflo. Run a workflow — drive an MCP workflow lifecycle (execute/pause/resume/cancel) or invoke + resume a native .claude/workflows/.js orchestration via the Workflow tool
Its SKILL.md is about 630 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 Agent Workflows. It works with Model Context Protocol. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit de590e1. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:

No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Workflow Run loads about 630 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 177 words of instructions outside code blocks.
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.
The automated check noted patterns worth knowing about, such as sudo or a known installer.

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.

Run a workflow — drive an MCP workflow lifecycle (execute/pause/resume/cancel) or invoke + resume a native .claude/workflows/.js orchestration via the Workflow tool. Workflow Run is an agent skill from ruvnet/ruflo.
Workflow Run fits situations like: agent Workflows work in your project.
Run `npx skills add ruvnet/ruflo --skill workflow-run -a claude-code`. Or copy the skill folder (plugins/ruflo-workflows/skills/workflow-run in ruvnet/ruflo) into .claude/skills/workflow-run in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ruvnet/ruflo --skill workflow-run -a codex`. Or copy the skill folder (plugins/ruflo-workflows/skills/workflow-run in ruvnet/ruflo) into .agents/skills/workflow-run in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ruvnet/ruflo --skill workflow-run -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/workflow-run, .gemini/skills/workflow-run, .github/skills/workflow-run and .opencode/skills/workflow-run in your project.
SKILL.md names no scripts, command-line tools or credentials: Workflow Run is instructions for the agent only. Its frontmatter pre-approves these tools: mcp__plugin_ruflo-core_ruflo__workflow_execute, mcp__plugin_ruflo-core_ruflo__workflow_run, mcp__plugin_ruflo-core_ruflo__workflow_pause, mcp__plugin_ruflo-core_ruflo__workflow_resume, mcp__plugin_ruflo-core_ruflo__workflow_cancel, mcp__plugin_ruflo-core_ruflo__workflow_status, Workflow, Read, Bash.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Workflow Run is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 630 tokens (SKILL.md is roughly 2.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Workflow Run: MCP Server Builder (anthropics/skills, 180k stars), MCP Server Builder (shareAI-lab/learn-claude-code, 78k stars), MCP Integration for Plugins (anthropics/claude-plugins-official, 37k stars) and Fastmcp Client CLI (PrefectHQ/fastmcp, 28k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
