n8n-loops

Skill1 starsChanged 3 months agoMITView on GitHub

Use for batching, pagination, "for each", Loop Over Items, Split Out, Aggregate, rate limits, or processing arrays in n8n. Default per-item execution often removes the need for an explicit loop node.

We split this skill into the rules it gives an agent

2 rules. About 0 are common, 2 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Use Split Out to explode arrays into items.

    line 18
  2. Distinctive:

    Use Loop Over Items when you need controlled batch size, wait-between, or partial commit.

    line 19

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

n8n Loops & Pagination

Author: Taghi Molavi

Defaults

  1. Most nodes already iterate items — do not add Loop Over Items just to "process each row".
  2. Use Split Out to explode arrays into items; Aggregate to recombine.
  3. Use Loop Over Items when you need controlled batch size, wait-between, or partial commit.
  4. HTTP pagination: prefer node built-in pagination options; else loop with cursor/page + clear exit condition.
  5. Fan-out on canvas is not parallel CPU — see lifecycle execution model. True concurrency → sub-workflows with async dispatch patterns.

Pagination checklist

  • Exit when next_cursor empty / page empty / has_more=false
  • Cap max pages as safety
  • Respect Retry-After / rate limits
  • Persist checkpoint for huge backfills (Data Table)

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
