n8n:testmax-assistant-ui

n8n-io/n8n/.agents/skills/testmax-assistant-ui/SKILL.md

Tests an n8n Assistant (Instance AI) UI feature end to end. Drafts the test paths from the feature and the diff, writes one Playwright script for each path, runs the paths in parallel on fresh n8n instances with a real LLM, and compares the main Assistant screens with master to find visual regressions. Shows live screenshots during the run, and builds one HTML report with video replays, step screenshots, LLM steps, tokens, cost and visual diffs. Use when the user wants to test an Instance AI or Assistant UI feature end to end, check that a UI change does not break existing screens, or says /testmax-assistant-ui.

Use whenever adding, modifying, or reviewing any Copilot, agent, LLM, AI, tool, permission, sandbox, MCP, model, telemetry, feature-gate, setting, configuration, or enterprise control—especially anything an organization or administrator may need to manage.

Run on every new Copilot/agent/LLM control and ANY change that adds a `policy:` field.

claude-api

anthropics/skills/skills/claude-api/SKILL.md

Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it "looks like a one-liner" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens). SKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).
