pp-n8n
Every n8n Public API endpoint, plus a local mirror that answers what is failing, what uses what, and what changed. Trigger phrases: `what n8n workflows are failing`, `which workflows use this credential`, `diff this workflow against prod`, `list my n8n workflows`, `use n8n`, `run n8n-pp-cli`.

What this skill does
n8n — Printing Press CLI Prerequisites: Install the CLI This skill drives the n8n-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: n8n-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.9 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead: If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. Manage workflows, executions, credentials, data tables, projects, and more on any self-hosted or cloud n8n instance. Sync once and get offline search, failure triage with 'executions failures', cross-workflow usage lookups with 'workflows uses', and node-level diffs between instances with 'workflows diff'. When to Use This CLI Use this CLI to operate an n8n instance from a terminal or agent: list and edit workflows, triage failed executions, find which workflows use a credential or node, compare workflows between instances, and manage data tables, tags, variables, and projects through the public API. Anti-triggers Do not use this CLI for: Designing new workflows from scratch with node documentation lookup; use n8n-mcp or the n8n editor Instance administration that needs the server shell (database backups, encryption keys, n8n export:credentials --decrypted) Reading credential secret values; the public API never returns them Unique Capabilities The local-store commands (workflows uses, workflows stale, credentials usage, executions failures) read the synced mirror. …
