feat(n8n-catalog): add 8 curated workflows and 4 new categories to catalog.json

[buddy0323]

Summary

• Expand config/n8n/catalog.json from version 1 → 2 with 8 production-ready curated workflows and 4 new categories
• Every new entry includes a diagram object (typed nodes + edges) surfaced by GET /api/workflows for dashboard visualisation
• All entries validated against the schema implied by routers/workflows.py: required fields (id, file, name, description, icon, category, dependencies, setupTime, featured), plus diagram

New workflows

ID	Name	Category	Key dependencies
llm-summarizer	LLM Summarizer	productivity	llama-server
rag-pipeline-trigger	RAG Pipeline Trigger	development	llama-server, qdrant
whisper-to-notes	Whisper Transcription to Notes	productivity	whisper, llama-server
scheduled-web-search	Scheduled Web Search	automation	llama-server
email-to-task	Email-to-Task via LiteLLM	automation	litellm
image-gen-webhook	Image Generation on Webhook	creative	comfyui
privacy-shield-test	Privacy-Shield Proxy Test	privacy	privacy-shield
openclaw-agent-trigger	OpenClaw Agent Trigger	agents	openclaw, llama-server

New categories

ID	Display name	Description
automation	Automation	Scheduled jobs, polling loops, and trigger-driven pipelines
creative	Creative	Image generation, art, and generative media
privacy	Privacy	PII redaction, compliance testing, and data protection
agents	Agents	Autonomous AI agents and multi-step reasoning workflows

Test plan

• GET /api/workflows returns all 17 entries with correct id, name, category, dependencies, and diagram fields
• GET /api/workflows/categories returns all 7 categories including the 4 new ones
• Each new workflow's category resolves to a valid key in categories
• POST /api/workflows/llm-summarizer/enable → 404 (workflow file not yet imported) — confirms dependency check runs before file check
• POST /api/workflows/email-to-task/enable with litellm service down → 400 with missing-dependency message
• POST /api/workflows/privacy-shield-test/enable with privacy-shield service down → 400 with missing-dependency message
• Diagram nodes and edges are present and non-empty for all 8 new entries
• Existing 9 workflows are unmodified (ids, files, descriptions, featured flags unchanged)

Review: Approve with caveat

The catalog changes are clean — additive only, valid JSON, no production code touched.

One issue to track

The 8 new entries reference .json workflow files (e.g., llm-summarizer.json) that are not included in this PR. The catalog will list workflows that can't be loaded. Are these files coming in a follow-up PR, or are they loaded from another source?

Minor note

email-to-task depends on litellm while others use llama-server — just confirming that's intentional.

Happy to merge once the workflow files question is clarified.

Thanks for the review — appreciate the thorough pass.

Workflow JSON files
You’re right to call this out. The catalog file fields point at exports under config/n8n/ on disk; the dashboard install path reads those files locally and they aren’t loaded from another source in this PR. The eight new entries follow the same pattern as the existing catalog rows, but the corresponding .json workflow exports aren’t included here yet.

Next step: I’ll follow up with a PR that adds those eight workflow files (or we can align on holding the merge until they land in the same branch — whichever you prefer) so “Enable” doesn’t 404 on missing files.

email-to-task / LiteLLM
Yes, that’s intentional. This template is named and described as “Email-to-Task via LiteLLM” (IMAP polling + LLM extraction through the LiteLLM gateway), so litellm is listed as the dependency instead of llama-server, which matches the other templates that use the local llama endpoint directly.

Happy to merge once the workflow-file follow-up is agreed — thanks again.
