## What it does

The skill pulls transactions with an empty category, applies the rules you already saved, and reports how many rows it handled. Whatever is left gets grouped by similar vendor names, with a suggested category per group. You confirm or adjust before anything is written.

Two Wilson tools do the work: `transaction_search` finds the uncategorized rows, `categorize` applies the rules. Matching is case-insensitive and looks at any part of the description. When a transaction fits several rules, the earliest one wins. Categories that are already set stay untouched unless you ask for an overwrite.

Confirmed rules can be saved — Wilson keeps them in the `categorization_rules` table, so they survive the session and apply to later imports. Without Wilson the skill walks through doing it by hand in Excel or Google Sheets: a rules sheet with pattern-category pairs and formulas built on `REGEXMATCH`. One catch there: `VLOOKUP` in Google Sheets does not support wildcards, so exact matching only gets you so far.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add openaccountant/skills --skill smart-categorize -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/smart-categorize/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/smart-categorize/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add openaccountant/skills --skill smart-categorize -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/smart-categorize/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add openaccountant/skills --skill smart-categorize -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/smart-categorize/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openaccountant/skills smart-categorize
```

2. **Manually: put the files in place**
- File: `.github/skills/smart-categorize/SKILL.md`

```bash
npx skills add openaccountant/skills --skill smart-categorize -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/openaccountant/skills --path shared/smart-categorize
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/smart-categorize/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add openaccountant/skills --skill smart-categorize -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/openaccountant/skills/tree/HEAD/shared/smart-categorize/SKILL.md

## When to use it
- find transactions with no category set
- apply saved rules to a fresh import
- group leftover rows by vendor name
- suggest a category for each vendor group
- save new rules so the same vendors stop coming back

## Example prompts
- categorize my uncategorized transactions
- show what's still uncategorized and suggest rules
- save the confirmed rules for future imports

# Smart Categorize

## Overview
Automatically categorize uncategorized transactions by matching vendor/description patterns against known rules. Uses existing categorization rules first, then suggests new rules for unmatched transactions based on common vendor names.

## Wilson Tools Used
- `categorize` — apply pattern-based categorization rules to transactions
- `transaction_search` — find uncategorized transactions

## Workflow
1. Use `transaction_search` to find all transactions where `category` is null or empty.
2. Run `categorize` to apply existing categorization rules (pattern matching on description field).
3. Report how many transactions were categorized by existing rules.
4. For remaining uncategorized transactions, group by vendor/description similarity.
5. Suggest category assignments for each vendor group (e.g., "SPOTIFY" -> Entertainment, "SHELL OIL" -> Transportation).
6. Ask the user to confirm or adjust the suggested categories.
7. Apply confirmed categories and optionally save new categorization rules for future imports.

## Without Wilson
You can categorize transactions manually in a spreadsheet:

### Setting Up Category Rules in Excel/Sheets
1. Create a reference sheet called "Rules" with two columns: `Pattern` and `Category`.
2. Add your vendor patterns:
   | Pattern | Category |
   |---------|----------|
   | AMAZON | Shopping |
   | WHOLE FOODS | Groceries |
   | SHELL | Transportation |
   | NETFLIX | Entertainment |
   | STARBUCKS | Dining |

3. In your transactions sheet, use a lookup formula in the Category column:
   - **Excel**: `=IFERROR(INDEX(Rules!B:B,MATCH("*"&"AMAZON"&"*",Rules!A:A,0)),"Uncategorized")` — but this only works for exact matches.
   - **Better approach with Excel**: Use a helper column with `=SUMPRODUCT` or VBA macro to do partial matching.
   - **Google Sheets**: `=IFERROR(VLOOKUP("*"&A2&"*",Rules!A:B,2,FALSE),"Uncategorized")` does not support wildcards in VLOOKUP.
   - **Practical Google Sheets approach**:
     ```
     =IF(REGEXMATCH(A2,"(?i)amazon"),"Shopping",
      IF(REGEXMATCH(A2,"(?i)whole foods|trader joe"),"Groceries",
      IF(REGEXMATCH(A2,"(?i)shell|chevron|exxon"),"Transportation",
      "Uncategorized")))
     ```

### Common Category Mapping
| Vendor Pattern | Suggested Category |
|---|---|
| AMAZON, TARGET, WALMART | Shopping |
| WHOLE FOODS, TRADER JOE, KROGER, SAFEWAY | Groceries |
| UBER EATS, DOORDASH, GRUBHUB | Dining |
| NETFLIX, SPOTIFY, HULU, DISNEY+ | Entertainment |
| SHELL, CHEVRON, BP, EXXON | Transportation |
| AT&T, VERIZON, T-MOBILE, COMCAST | Utilities |
| CVS, WALGREENS, PHARMACY | Healthcare |
| VENMO, ZELLE, PAYPAL (person-to-person) | Transfers |
