What it does
Workflow Builder is an agent skill from n8n-io/n8n, published by the product's own GitHub organization. Load before calling build-workflow. Default path for all single-workflow work: new one-off workflows, existing-workflow edits, verification repairs, and workflow-local data tables. Write or edit a workspace source file, run workflow-sdk validate via workspaceexecutecommand, then call build-workflow with filePath. When the workflow creates or writes Data Tables, load data-table-manager first, then this skill. Do not load planning or create-tasks first. Load planning only when multiple coordinated workflows or…
Its SKILL.md is about 15k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `references/compositional-workflows.md`, `references/config-eval-playbook.md` and `references/config-evals.md`).
It sits in Productivity & Automation, covering Workflow automation. It works with n8n, TypeScript and Model Context Protocol. The repository describes itself as: Fair-code workflow automation platform with native AI capabilities. Combine visual building with custom code, self-host or cloud, 400+ integrations.
When your agent uses it
- Explicit one-off tasks that can be done by a single node execution: load one-off-operations and run the node with nodes(action=execute)
- Tasks that involve Workflow automation
Example prompts
- “execute”
- “/workflow-builder”
Requirements
- A credential in YOUR_API_KEY
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Knowledge base — consult before
- Runtime skills — when another skill matches (e.g. data-table-manager,
- Official n8n docs — for credential setup, product features, hosting, or
What it can do on your machine
Read from SKILL.md and the folder at commit 60ad29f. 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
Shell commands in SKILL.md call:
node
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 Builder loads about 15k tokens when it runs, and up to ~35k if it reads all its reference files. Until then it costs about 229 tokens; SKILL.md has 7,525 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.
Safety
Auto-check: warnings
The automated check found patterns that need a careful read before installing.
- WarningContains instruction-override wording (e.g. “without asking the user”)SKILL.md:1043
ired, say plainly that setup is needed; do not tell the user to open a setup
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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 7,525 words (~14,510 tokens).

With the skills CLI, run `npx skills add n8n-io/n8n --skill workflow-builder -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-builder, .gemini/skills/workflow-builder, .github/skills/workflow-builder and .opencode/skills/workflow-builder in your project.
What does Workflow Builder need to run?
Going by SKILL.md and its folder, Workflow Builder needs the command-line tools its instructions call (node). Our summary lists: A credential in YOUR_API_KEY.
Does Workflow Builder access the network?
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.
Is Workflow Builder safe to install?
Our automated static check of SKILL.md flagged 1 warning(s): contains instruction-override wording (e.g. “without asking the user”). Read the flagged lines before installing; the check is not a guarantee either way.
What licence does Workflow Builder use?
