npx skills add https://github.com/n8n-io/n8n --skill planning
Use this skill to design a dependency-aware task graph in the orchestrator and
submit it with create-tasks. Do not spawn another agent and do not use
incremental plan item tools.
Before calling create-tasks, load it via load_tool (search "create tasks" if
it is not visible).
Stop and use workflow-builder + build-workflow instead when the request is:
Do not call create-tasks just to get approval, verification, or a checklist for
a single workflow. Workflow verification is automatic from structured build
outcomes after build-workflow.
Planning is only for work that needs coordination: multiple workflows,
dependencies between workflows, shared data-table schema or migration work across
tasks, multiple durable artifacts, broad best-practice research across many
sources, genuinely ambiguous business-process architecture that cannot be
resolved with one build-workflow call, or an explicit user request to review a
plan first.
If shared data tables are involved, load data-table-manager before this skill
and carry the relevant table guidance into workflow task specs. Clear
single-workflow builds and existing-workflow edits use workflow-builder with
build-workflow directly. Standalone data-table work uses data-table-manager
with direct data-tables and parse-file calls.
Consult the knowledge base before planning. Read the relevant .md guides
and templates for each technique the request involves (knowledge-base/index.json,
knowledge-base/best-practices/index.json, and linked files). Use
workspace_execute_command with rg or find under knowledge-base/templates/
to locate matching SDK examples — never load templates/index.json wholesale.

Done when.
Required effects, list every observable action the user asked for, suchas send email, send Telegram, write Google Sheets, create Notion pages, upsert
Data Table rows, or post one Slack summary.
Required branches, state partial-failure behavior when multiple effectsstart from the same trigger, and state whether no-results or invalid-input
paths need an explicit notification, fallback, log, or no-op.
Required data, name fields needed by later conditions, filters, ranking,response messages, or downstream effects, and note when those fields must
remain available after side-effect nodes that replace item JSON.
Explicit constraints, preserve concrete user-provided resource names,channels, tables, labels, URLs, and required node families or mechanisms. If
the user explicitly says to use a node family or mechanism such as HTTP
Request, webhook, form, MCP, or a service-native node, treat that as a hard
requirement unless it is impossible or contradicts another stated requirement.
Do not move those values to assumptions, replace them with placeholders, or
silently swap them for a more convenient alternative.
Empty/invalid behavior, distinguish data that invalidates the whole itemfrom data that only affects one requested effect. For multi-effect intake
workflows, do not turn a field into a workflow-wide rejection requirement
merely because one message or side effect uses it.
Done when, write observable acceptance checks, including final actionsand branch behavior. Do not write node-by-node wiring or fake user data.

sub-workflows that are only intermediate artifacts inside a larger main

for example validating a named Slack channel that affects the architecture. Do
not turn resource lookup into a credential-choice question unless the
multiple-credentials rule applies.
Workflow verification is automatic from structured build outcomes. Do not add
routine "verify this workflow" checkpoint tasks for every workflow.
Checkpoint tasks are exceptional semantic checks. Use them for cross-workflow
contracts, confirming a report combines upstream data correctly, validating a
business invariant across deliverables, or checking a condition that cannot be
covered by normal runtime verification.
Do not add checkpoints for routine verification-only work.
If the user rejects the plan with requested changes, revise surgically, load
create-tasks via load_tool if needed, and call create-tasks again in the
same orchestrator run with
planningContext.source: "planning-skill".
If the user denies the plan outright, stop. Do not call create-tasks again in
the same message group.
