Quick reference for n8n patterns. Full docs /AGENTS.md

Authors and calibrates Instance AI evaluations that build standalone n8n Agents through Agent Builder. Use when a change under packages/cli/src/modules/agents affects build-agent routing, Agent setup, model or credential selection, tools, MCP servers,…

Authors a new Instance AI workflow or Agent eval case — written locally as JSON, calibrated against a real build, then pushed to the LangTracer suite CI runs — build cases, behaviour/process cases, credential cases, and seeded (mid-conversation) cases — with…

Guides work on `packages/frontend/editor-ui` experiments. Use when creating, extending, wiring, testing, reviewing, or retiring editor-ui experiments, PostHog feature flags, experiment key indexes, variants, stores/composables, persisted experiment state, or…

Deploy a temporary n8n test instance (or generate a local docker run command) via the internal "Nathan" bot, from the repo instead of Slack. Use after opening a PR to offer the user a live test instance, or whenever someone asks to spin up / deploy a test…

Adds, migrates, or updates n8n Public API v1 endpoints with @PublicApiController — public DTOs, API-key and RBAC scopes, cursor pagination, OpenAPI + coverage wiring, and tests. Use when working under packages/cli/src/public-api/v1/ or when exposing an…

Reproduce a bug from a Linear ticket with a failing test. Expects the full ticket context (title, description, comments) to be provided as input.

Use when you want to expose an n8n workflow as a tool the coding agent can call. Two cases. (1) Wrap n8n API capabilities the MCP doesn't natively expose: folder deletion, project create/rename, tag rename/delete, instance metadata, credential creation. (2)…

Use when working with n8n workflows in any capacity. The always-on protocol for the n8n-skills plugin, loaded by the SessionStart hook every session. Routes to the right skill, summarizes every n8n MCP tool (closing the deferred-description gap), and lists…

Use when starting, designing, organizing, finishing, or shipping an n8n workflow. Covers visual layout (sticky notes), descriptions that capture the *why*, node names, validation, testing, folders/projects, and publishing. Triggers on…

Use when building or editing any AI feature in n8n: AI Agents, Text Classifier, Information Extractor, Sentiment Analysis, Summarization Chain, Basic LLM Chain, embeddings, vector stores, single one-shot LLM calls, or AI media generation (image / audio /…

Use when handling files, images, attachments, or binary data in n8n, OR when an AI agent needs to take a user-uploaded file as tool input or return a generated file. For Data Tables (schemas, dedup, persistent state), see the separate n8n-data-tables-official…

Use when the user reaches for a Code node, mentions writing JavaScript or Python in n8n, or any custom logic comes up in workflow design. Triggers on "Code node", "Code", "JavaScript", "Python", "custom logic", "transform data", "$input", "$json…

Use when an n8n workflow isn't working, errors appear, results don't match what was expected, or the user says "this isn't working." Triggers on errors, unexpected output, "it's not working", "why is this happening", "the workflow stopped", failure…

Use when building any webhook-triggered workflow, scheduled/production-bound workflow, wiring a per-node error output, or any workflow where silent failure would drop user-visible work. Triggers on "webhook", "respond to webhook", "API", "production",…

Set up and verify the n8n MCP connection before using n8n tools. Run on the first turn touching n8n, or when tools are missing, OAuth fails, a request times out, or the user asks to connect a new instance. Uses a bundled public-client OAuth setup helper and…

Build an n8n workflow using the code open in the workspace, then validate and test it before calling it done. Use when the user asks to create, build, or change an n8n workflow, to automate a task, to add a scheduled job or a webhook, or to connect n8n to the…

Diagnose an n8n workflow that failed, produced the wrong result, or stopped running, working from execution data rather than the workflow definition. Use when the user reports a broken, failing, or flaky workflow, asks why a run failed, or asks what changed.…

Rules that make an LLM's output read like a person wrote it. They apply to everything the model produces: chat replies, blog drafts, emails, docs, summaries, commit messages. The register carries over to anything a human will read.

Maintain the n8n DevRel video-resources repo: the layout, naming, per-video folders, and the root README index. Use whenever adding resources for a new YouTube video (workflow JSON, prompts, notes), editing an existing video's folder, renaming or reorganizing…

Authors and reviews n8n documentation pages following the n8n docs style and contribution guides. Use when writing new doc pages, editing existing docs, reviewing doc PRs, or checking content against the style guide. Covers writing style, GitBook formatting…
