# Runbook: Budget import from N26 CSV → Yuvomi

Distil a bank-export CSV into Yuvomi's Budget and Subscriptions modules using
the `yuvomi-mcp` tools. Run this whenever a new CSV period needs to be
summarised into targets and fixed costs.

---

## Prerequisites

- `yuvomi-mcp` is running on LXC 129 and connected as an MCP server in Claude.
- The CSV is an N26 export (columns: Booking Date, Value Date, Partner Name,
  Partner Iban, Type, Payment Reference, Account Name, Amount (EUR), …).
- API token: `homelab secret yuvomi-api-token` (decrypts on any enrolled client).
- Direct API base: `https://house.hubris.network/api/v1`

---

## API quirks (Yuvomi ≤ 0.77.x)

- **Subscriptions live under `/budget/subscriptions`**, NOT `/subscriptions/`.
  A top-level `/subscriptions` route returns 404.
- `GET /budget/subscriptions` → `{ data: { subscriptions: [...], summary: {...} } }`
- `GET /budget/subscriptions/meta` → `{ data: { categories: [...], payment_methods: [...] } }`
- `POST /budget/subscriptions` → create a subscription (name, amount, billing_cycle,
  cycle_interval, next_payment_date, currency, category_id, payment_method_id required)
- `GET /budget/` (no month) → returns only **non-recurring** base entries.
  Use `GET /budget/?month=YYYY-MM` to get all entries (recurring + one-time) for a month.
- `GET /budget/categories` → expense category keys + income category names (German keys
  like `"Erwerbseinkommen"`, `"Sozialleistungen"`, `"Geschenke & Transfers"`).
- Budget entries: `amount` positive = income, negative = expense.
- Recurring entries: set `is_recurring: 1` + `recurrence_interval: "monthly"`.
  The `date` field sets the start month.
- `recurrence_virtual: 1` smooths non-monthly amounts across all months in the summary
  (e.g. 55.08 € quarterly → shows as ~18.36 €/month).
- Custom RRULE strings (`recurrence_rule`) are **not accepted** by the API — use
  `cycle_interval` on the subscription instead, or `recurrence_interval` on budget entries.

## Step 1 — Categorise the transactions

Skip these as internal/already-covered:
- Fixed costs you'll enter as **subscriptions** (Miete, SWM, SYNVIA, Hundefutter,
  Netflix, Grover, Rundfunk ARD, KuKita, Lillydoo)
- Internal transfers (The Joy Pot ↔ Cookie, Hauptkonto, Tagesgeldkonto splits)
- Identified income (Cookie Share, Kindergeld, Pocket Money credits, Distributor)
- Fun Money pass-throughs (in and out same month → net zero)

**Variable expense taxonomy:**

| Category key | Subcategory key | Examples |
|---|---|---|
| `food` | `groceries` | E-Center, Knuspr, EDEKA, Tegut, VollCorner, Lidl, Netto, REWE, KoRo, Roast Market |
| `food` | `restaurants_bars` | Restaurants, Lieferando, Cafes, Zeit für Brot, Baobab, Höflinger |
| `personal_health` | `beauty_cosmetics` | DM, Rossmann |
| `personal_health` | `pharmacy` | Apotheke, MVZ Dermatologie |
| `transport` | `apps_taxi` | Uber, RYD GMBH, MVG, Handyparken |
| `shopping_clothing` | `gifts` | Children products: Schlummersack, Catchy Kids, SP EVERY., Dukal, Berger-Lernwelt |
| `shopping_clothing` | `clothes_shoes` | Zalando, Ernsting's, Schuhmair, Thalia, Vinted, Airbnb, Hotel at Booking.com |
| `shopping_clothing` | `electronics` | Amazon, AMZN Mktp DE |
| `housing` | `renovation_maintenance` | IKEA, Markus Festl, Granit, Sostrene Grene, Mol* tischdecken, Gaertnerei, Dehner |
| `education` | `courses_college` | Kathrin Orlob (PEKiP), Nerina Aupperle |
| `leisure` | `streaming` | WOW wowtv.de |
| `financial_other` | `bank_fees` | Unidentified PayPal, Ratepay, N26 fees |
| `Geschenke & Transfers` | *(income)* | One-off incoming transfers |

---

## Step 2 — Create subscriptions

```
get_subscriptions_meta()    ← get category_id and payment_method_id
```

**Standard Cookie household subscriptions (as of 2026-07):**

| Name | Amount | billing_cycle | cycle_interval | category_id | payment_method_id |
|---|---|---|---|---|---|
| Miete | 1080.00 | monthly | 1 | 6 (Other) | 6 (Bank Transfer) |
| Strom (SWM) | 79.00 | monthly | 1 | 3 (Utilities) | 6 |
| Internet / TV / Telefon | 29.99 | monthly | 1 | 3 (Utilities) | 6 |
| Hundefutter | 75.00 | monthly | 1 | 6 (Other) | 6 |
| Netflix | 8.00 | monthly | 1 | 1 (Entertainment) | 6 |
| Grover | 16.90 | monthly | 1 | 6 (Other) | 2 (Debit Card) |
| Rundfunk ARD / ZDF | 55.08 | monthly | 3 | 1 (Entertainment) | 6 |
| KuKita Daycare (Leon) | 503.00 | monthly | 1 | 5 (Education) | 6 |
| Lillydoo diapers | 56.70 | monthly | 2 | 4 (Health) | 3 (PayPal) |

Monthly equivalent total: **1,838.60 €** (Yuvomi applies cycle_interval to prorate).

---

## Step 3 — Add recurring income entries

```
stage_add_budget_entry(
    title="Kindergeld",
    amount=55.00,
    category="Sozialleistungen",
    date="YYYY-MM-01",
    is_recurring=True,
    recurrence_interval="monthly",
)
commit_pending(pending_id)
```

**Standard recurring income:**

| Title | Amount | category |
|---|---|---|
| Kindergeld | +55.00 | Sozialleistungen |
| Cookie Share | +2650.00 | Erwerbseinkommen *(see recommended amount below)* |

---

## Step 4 — Post variable transactions

For each non-skipped CSV row, call `stage_add_budget_entry` with the mapped
category/subcategory and the actual transaction amount and date. Use the Partner
Name + Payment Reference as the title (truncate to 100 chars).

---

## Step 5 — Verify

```
get_budget_summary("YYYY-MM")
list_subscriptions()
```

Expected for a full month with KuKita:
- Fixed expenses ≥ 1,838 € (subscriptions)
- Variable expenses ≥ 500 € (groceries alone)

---

## Cookie Share: how much to transfer monthly

Calculated from Jan–Jun 2026 data (Cookie account, one-offs stripped):

| | €/month |
|---|---|
| **Fixed costs (subscriptions)** | **1,839** |
| Miete | 1,080 |
| KuKita *(permanent from Jul 2026)* | 503 |
| Strom + SYNVIA + Rundfunk + Netflix + Grover + Hundefutter + Lillydoo | 256 |
| **Variable (6-month averages)** | **1,032** |
| Groceries | 595 |
| Children products | 142 |
| Dining & cafes | 100 |
| Transport | 66 |
| Drugstore | 52 |
| Clothing, Amazon, Pharmacy | 77 |
| **Total monthly spend** | **≈ 2,871** |
| Minus Kindergeld (fixed income) | −55 |
| Minus Pocket Money (conservative ~600 €) | −600 |
| **→ Recommended Cookie Share** | **≈ 2,650 €** |
| With 200 € buffer | **≈ 2,850 €** |

**Current Cookie Share (Jun 2026): 1,995 € — shortfall ~655 €.**

The gap was covered by irregular Pocket Money top-ups (avg 962 €/mo over 6 months, but
highly variable: 121 €–3,000 €). KuKita starting in June is the biggest step-up; raising
Cookie Share to **2,650 €** makes the budget self-sufficient without relying on top-ups.

## Changelog

### 2026-06-29 — Corrections from first real import
- Subscriptions endpoint is `/budget/subscriptions`, NOT `/subscriptions/` (404).
- `recurrence_rule` RRULE strings are rejected by the API; use `cycle_interval` instead.
- `GET /budget/` (no filter) returns only non-recurring entries; use `?month=` for full view.
- Added Cookie Share recommendation (2,650 €/month) based on 6-month expense analysis.
- Added full category taxonomy table.
