在 n8n 的程式碼節點中撰寫 Python 程式碼。當使用者明確指定使用 Python 於 n8n 程式碼節點時使用此技能。
此技能專為在 n8n 工作流程中的程式碼節點內撰寫 Python 程式碼而設計。它適用於需要利用 Python 標準函式庫（例如 regex、hashlib、statistics）的場景，或當使用者明確偏好 Python 而非 JavaScript 時。技能文件強調，95% 的用例建議使用 JavaScript，僅在特定需求下才採用 Python。它涵蓋了 `_input`、`_json`、`_node` 語法的使用，以及 Python 在 n8n 程式碼節點中的限制。特別地，對於 AI 代理可呼叫的自訂程式碼工具（`@n8n/n8n-nodes-langchain.toolCode`），應使用 `n8n-code-tool` 技能，因為其輸入為 `_query`，且回傳必須是字串。此技能支援 n8n 平台，並提供開發者撰寫 Python 程式碼的指引。

在 n8n 的程式碼節點中撰寫 Python 程式碼。當在 n8n 中撰寫 Python、使用 _input/_json/_node 語法、操作標準函式庫，或需要了解 Python 在 n8n 程式碼節點中的限制時使用。請在此技能中用於使用者明確要求 n8n 程式碼節點使用 Python 的情況。注意 — 對於 95% 的用例，建議使用 JavaScript — 僅在使用者明確偏好 Python，或任務需要 Python 特定的標準函式庫能力（regex、hashlib、statistics）時，才使用 Python。例外 — 對於 AI 代理可呼叫的自訂程式碼工具（@n8n/n8n-nodes-langchain.toolCode），請改用 n8n-code-tool 技能（輸入為 _query，回傳必須是字串）。
This repo contains 6 individual skills — each has its own dedicated page.
Write JavaScript code in n8n Code nodes. Use when writing JavaScript in n8n, using $input/$json/$node syntax, making HTTP requests with this.helpers / the $helpers global, working with dates using DateTime, troubleshooting Code node errors, choosing between Code node modes, or doing any custom data transformation in n8n. Always use this skill when a workflow needs a Code node — whether for data aggregation, filtering, API calls, format conversion, batch processing logic, or any custom JavaScript. Covers SplitInBatches loop patterns, cross-iteration data, pairedItem, and real-world production patterns. Also use when asked why a Code node or workflow is slow, which execution mode is faster, or how to cut per-item overhead on large datasets. EXCEPTION — for the AI-agent-callable Custom Code Tool (@n8n/n8n-nodes-langchain.toolCode, a tool attached to an AI Agent), use the n8n-code-tool skill instead; it has a different runtime contract.
Validate n8n expression syntax and fix common errors. Use when writing n8n expressions, using {{}} syntax, accessing $json/$node variables, troubleshooting expression errors, mapping data between nodes, or referencing webhook data in workflows. Use this skill whenever configuring node fields that reference data from previous nodes — expressions are how n8n passes data between nodes, and getting the syntax wrong is the most common source of workflow errors. Also use when asked whether a complex expression hurts performance.
Expert guide for using n8n-mcp MCP tools effectively. Use when searching for nodes, validating configurations, accessing templates, managing workflows, managing credentials, auditing instance security, or using any n8n-mcp tool. Provides tool selection guidance, parameter formats, and common patterns. IMPORTANT — Always consult this skill before calling any n8n-mcp tool — it prevents common mistakes like wrong nodeType formats, incorrect parameter structures, and inefficient tool usage. If the user mentions n8n, workflows, nodes, or automation and you have n8n MCP tools available, use this skill first.
Operation-aware node configuration guidance. Use when configuring nodes, understanding property dependencies, determining required fields, choosing between get_node detail levels, or learning common configuration patterns by node type. Always use this skill when setting up node parameters — it explains which fields are required for each operation, how displayOptions control field visibility, and when to use patchNodeField for surgical edits vs full node updates.
Interpret validation errors and guide fixing them. Use when encountering validation errors, validation warnings, false positives, operator structure issues, or need help understanding validation results. Also use when asking about validation profiles, error types, the validation loop process, or auto-fix capabilities. Consult this skill whenever a validate_node or validate_workflow call returns errors or warnings — it knows which warnings are false positives and which errors need real fixes.
Proven workflow architectural patterns from real n8n workflows. Use when building new workflows, designing workflow structure, choosing workflow patterns, planning workflow architecture, or asking about webhook processing, HTTP API integration, database operations, AI agent workflows, batch processing, or scheduled tasks. Always consult this skill when the user asks to create, build, or design an n8n workflow, automate a process, or connect services — even if they don't explicitly mention 'patterns'. Covers webhook, API, database, AI, batch processing, and scheduled automation architectures. Also use when optimizing a slow workflow or speeding up large-item-count processing (node count, batchSize, all-items vs per-item).
Gemini CLI one-shot prompts, summaries, generation, skills, hooks, MCP, or Gemma routing.
Fetch GitHub issues, select candidates, spawn background fix agents, open PRs, and optionally process PR review comments.
Create, edit, audit, tidy, validate, or restructure AgentSkills and SKILL.md files.
Search, install, update, sync, or publish agent skills with the ClawHub CLI and registry.
Delegate coding work to Codex, Claude Code, or OpenCode as background workers; not simple edits or read-only code lookup.
List, configure, authenticate, call, and inspect MCP servers/tools with mcporter over HTTP or stdio.
