## What it does

The skill inventories custom fields for `contacts`, `companies`, and `deals` via HubSpot Properties API v3. It checks for filled values across records and inspects references inside active forms, lists, or workflows.

Attributes with zero filled records or names containing `test`, `temp`, or `old_` are queued for cleanup. Salesforce sync properties with the `hs_salesforce_*` prefix and calculated fields require explicit confirmation. The process archives fields first via API so historical data stays recoverable.

Execution requires Python 3.10+ with `uv` alongside a `HUBSPOT_ACCESS_TOKEN` set in `.env`. Without `crm.schemas.*.read` and `crm.schemas.*.write` scopes, the HubSpot API will reject the schema requests.

## Requirements
- Works with: HubSpot, Salesforce

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add TomGranot/hubspot-admin-skills --skill cleanup-properties -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add TomGranot/hubspot-admin-skills --skill cleanup-properties -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add TomGranot/hubspot-admin-skills --skill cleanup-properties -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install TomGranot/hubspot-admin-skills cleanup-properties
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add TomGranot/hubspot-admin-skills --skill cleanup-properties -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/TomGranot/hubspot-admin-skills --path skills/cleanup-properties
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add TomGranot/hubspot-admin-skills --skill cleanup-properties -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/TomGranot/hubspot-admin-skills/tree/HEAD/skills/cleanup-properties/SKILL.md

## When to use it
- audit unused custom properties across HubSpot records
- archive obsolete fields without losing reporting history
- inspect field dependencies in forms and automation workflows
- flag Salesforce sync properties before accidental removal

## Example prompts
- Scan deals for empty custom properties and prepare an archive list
- Find all contact properties containing test or temp in their names
- Check custom company properties before removing legacy integration fields

# Cleanup Properties

Remove or archive unused custom properties. Property bloat slows down forms, confuses users, and makes data mapping harder.

## Prerequisites

- A HubSpot service key (`HUBSPOT_ACCESS_TOKEN` in `.env`; an existing legacy private app token also works) with `crm.schemas.*.read` and `crm.schemas.*.write` scopes
- Python 3.10+ with [`uv`](https://github.com/astral-sh/uv)

## Step-by-Step Instructions

### Stage 1: Plan

Confirm with the user before starting:

1. Archive-first policy (recommended) or direct deletion for clearly dead test properties?
2. Is a Salesforce (or other CRM) sync active? If yes, get the sync property mapping before touching anything.

### Stage 2: Before

Inventory custom properties for each object type via the Properties API (v3):

```python
import os, requests
from dotenv import load_dotenv

load_dotenv()
TOKEN = os.environ["HUBSPOT_ACCESS_TOKEN"]
BASE = "https://api.hubapi.com"
HEADERS = {"Authorization": f"Bearer {TOKEN}", "Content-Type": "application/json"}

for obj_type in ["contacts", "companies", "deals"]:
    resp = requests.get(f"{BASE}/crm/v3/properties/{obj_type}", headers=HEADERS)
    resp.raise_for_status()
    custom_props = [p for p in resp.json()["results"] if not p.get("hubspotDefined")]
```

For each custom property, record: name, label, object type, type, group, number of records with a value (requires search queries), whether it is used in any form/workflow/list.

### Stage 3: Execute

**Safe to delete:**
- Properties with zero populated records and not used in any form, workflow, or list
- Properties with names containing "test", "temp", "old_", "copy_of"
- Properties created by deactivated integrations

**Handle with care:**
- **Salesforce sync properties** (`hs_salesforce_*` prefix or mapped in sync settings) — do not delete without coordinating with the Salesforce admin
- **Form fields** — check if the property is used on any active form before deleting
- **Workflow dependencies** — check if any workflow reads or sets this property
- **Calculated properties** — check if other calculated properties reference this one

**Archive instead of delete** when:
- The property has historical data that might be needed for reporting
- You are unsure whether anything depends on it

Archive candidates via `DELETE /crm/v3/properties/{objectType}/{propertyName}` (this archives — the property moves to the archived state) after presenting the list to the user and getting explicit confirmation.

### Stage 4: After
