# n8n Workflows

Running on `n8n-agent` at port `18808`. See [[Infrastructure/Services/Docker Services]] for service details.

## Division of labor

- **n8n:** schedules, webhooks, polling, retries, credentials, native integrations, and lightweight HTTP/API glue.
- **Atlas / Hermes:** reasoning-heavy decisions, debugging, code/config changes, workflow repair, and higher-quality synthesis.
- **Swarm local services:** cheap local LLM (`llama.cpp` on host `0.0.0.0:18806`, reached from n8n as `http://172.19.0.1:18806`), embeddings (`Ollama` on `18807`), transcription (`Whisper` on `18811`), TTS (`Kokoro` on `18805`), and search (`SearXNG` on `18803`, Brave MCP on `18802`).
- **Obsidian:** durable human-readable notes and summaries.
- **Telegram / Discord:** notifications and quick approval loops.

## Core workflows

### IMAP Inbox Triage + Obsidian Notes
- **ID:** `9sFwRyUDz51csAp7`
- **Status:** ✅ Active
- **Trigger:** Schedule polling every 15 minutes
- **Account:** `wills_portal` IMAP
- **Local LLM:** `gemma-4-26B-A4B-it-UD-IQ2_M.gguf` via `llama.cpp` on `18806`
- **Purpose:** reads unseen IMAP mail, drops obvious noise, judges ambiguous mail with the local LLM, sends signal digests to Telegram, and writes per-email notes to the shared Obsidian vault
- **Details:** see [[Infrastructure/Automation/n8n IMAP Triage Pipeline]]

### Gmail Inbox Monitor + Obsidian Notes
- **ID:** `whtdorf7yJMVYeHm`
- **Status:** ⚠️ Active, but startup logs still report a Gmail Trigger warning (`undefined`)
- **Trigger:** Gmail-triggered monitor flow
- **Purpose:** watches Gmail, applies local triage, writes signal notes to Obsidian, and supports notification routing

### Calendar to Obsidian Notes
- **ID:** `QRCCdHNXZUHc2Oz4`
- **Status:** ✅ Active
- **Trigger:** scheduled sync
- **Purpose:** fetches upcoming calendar events and writes/updates notes in the shared vault
- **Credential:** `Google Calendar account`

### Nightly Obsidian Vault Sync
- **ID:** `75JCevkdgkyCr2qH`
- **Status:** ✅ Active
- **Trigger:** nightly cron (`45 23 * * *`)
- **Local LLM:** `gemma-4-26B-A4B-it-UD-IQ2_M.gguf` via `llama.cpp` on `18806`
- **Purpose:** fetches key operational notes plus live n8n/LLM health, uses the local LLM to generate a concise nightly vault sync note, and writes it to `Notes/YYYY-MM-DD Nightly Vault Sync.md`
- **Details:** see [[Infrastructure/Automation/n8n Nightly Vault Sync]]

### OpenClaw Action Bus
- **ID:** `Jwi54VWMdlLqYnRo`
- **Status:** ✅ Active
- **Type:** webhook / action router
- **Purpose:** controlled execution path for approved actions and structured OpenClaw-to-n8n integration

### OpenClaw Reminder Webhook
- **ID:** `RUR1CGn0ikkxbPin`
- **Status:** ✅ Active
- **Type:** webhook
- **Purpose:** reminder ingress path for simple reminder-style automation

## Near-term personal ops workflows

### Swarm Health Watchdog
- **ID:** `lDKocSFXBQWQrDd3`
- **Status:** ✅ Active
- **Trigger:** every 15 minutes
- **Purpose:** checks the core swarm endpoints from inside the n8n container and sends Telegram + Discord alerts after two consecutive failures, plus recovery messages.
- **Checks:** Brave MCP `18802`, SearXNG `18803`, LiteLLM `18804`, Kokoro `18805`, llama.cpp `18806`, Ollama embeddings `18807`, n8n `18808`, Whisper `18811`.
- **Implementation note:** uses the Docker bridge gateway `172.19.0.1` for host-published services and `127.0.0.1:5678` for n8n self-health.
- **Limitation:** Docker health state is not yet available inside n8n because the Docker socket is not mounted; alerts include endpoint status and suggested host-side checks instead.

### n8n Failure Digest
- **ID:** `G9ylNbHbnJ6fWX2C`
- **Status:** ✅ Active
- **Trigger:** hourly plus manual trigger
- **Purpose:** queries recent failed n8n executions, groups failures by workflow/node/error, and sends a concise Telegram digest.

### Voice Memo Capture (Audio URL + Local Whisper)
- **ID:** `El1BHJZ56JlzhrRZ`
- **Status:** ✅ Active
- **Type:** webhook
- **Purpose:** accepts an audio URL, downloads the audio, transcribes with local Whisper on `18811`, summarizes with local llama.cpp, writes transcript/summary/action items to Obsidian, and sends a Telegram notification.

### Web-to-Notes Capture (Local LLM + Obsidian)
- **ID:** `GSmzuA5dgGgyRg5v`
- **Status:** ✅ Active
- **Type:** webhook
- **Purpose:** accepts a URL, fetches the page, extracts readable text, summarizes with local llama.cpp, and writes a clean markdown note to Obsidian.

### Daily OpenClaw Session Digest
- **ID:** `qqYwAD05AvRHrHPc`
- **Status:** ✅ Active
- **Trigger:** nightly cron (`15 23 * * *`, 11:15 PM Pacific)
- **Local LLM:** local llama.cpp path
- **Purpose:** pulls recent OpenClaw sessions via gateway RPC, curates transcripts with the local LLM into a structured daily note (Summary, Decisions, Tasks, Follow-ups, Durable Facts), and writes it to `Notes/YYYY-MM-DD OpenClaw Session Digest.md` in the shared vault.
- **Fallback:** if the local LLM fails, writes a metadata-only note instead of silently dropping.

## Archived / recovery notes

### IMAP Inbox Triage + Obsidian Notes (squareffect)
- **ID:** `xjUoQf97TkBrawc8`
- **Status:** 🗄️ Archived on 2026-05-12 after SQLite recovery because workflow JSON was empty/unrecoverable.

### IMAP Inbox Triage + Obsidian Notes (wills-portal duplicate)
- **ID:** `kHDK9QdUSiAJ8rCM`
- **Status:** 🗄️ Archived on 2026-05-12 after SQLite recovery because workflow JSON was empty/unrecoverable.

## Operational notes

- n8n DB was recovered on 2026-05-12 from a `SQLITE_CORRUPT: database disk image is malformed` crash loop using SQLite `.recover`, then repaired until `n8n export:workflow --all` succeeded.
- Host-side DB backups from the repair were stored under `/home/will/lab/swarm/.n8n-db-backups/` and should remain untracked.
- `n8n export:workflow --all` was re-verified on 2026-05-12 and exported 13 workflows successfully.
- n8n health after recovery: `http://127.0.0.1:18808/healthz` returns `{"status":"ok"}` and the container is healthy.
- Startup still logs the known Gmail Trigger warning (`undefined`) for `Gmail Inbox Monitor + Obsidian Notes`; this is the next cleanup target.
- On 2026-05-28, `llama-server.service` was rebound from `127.0.0.1:18806` to `0.0.0.0:18806` so n8n workflows can call the local LLM through the Docker bridge gateway at `172.19.0.1:18806`. Verification commands: host `curl http://127.0.0.1:18806/v1/models`; container `docker exec n8n-agent wget -qO- http://172.19.0.1:18806/v1/models`.
