## What it does

The skill sets up ten foundational active dynamic lists in HubSpot using Lists API v3. Its `scripts/execute.py` script sends list definitions to `POST /crm/v3/lists`, categorizing contacts by lifecycle stages (Lead, MQL, SQL, Customer), marketing status, and recent activity. It also generates lists for target account tiers. Existing lists trigger HTTP 409 responses and are skipped cleanly. The script logs IDs into a CSV.

Execution requires Python 3.10+ and the `uv` package manager. Without `HUBSPOT_ACCESS_TOKEN` in `.env` holding `crm.lists.read` and `crm.lists.write` scopes, the script will fail immediately. It also expects the `company_segment` property on company records. Adjust the configuration if your portal uses a different property name.

Eight additional segments require manual setup in the HubSpot UI. The skill details criteria for master sendable lists, target job titles, and inactive contacts. You can adjust the engagement window by editing `ACTIVE_WINDOW_DAYS`.

## Requirements
- Works with: HubSpot

### Cursor

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

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

### GitHub Copilot

# Build Smart Lists for Segmentation

Create the core active (dynamic) lists that serve as the foundation for all marketing campaigns, sales prioritization, and database health monitoring. Ten foundation lists are created automatically via the Lists API (v3); a further set of advanced segments is built in the UI.

## Why This Matters

Without predefined lists, every email campaign requires building filters from scratch, there is no standardized definition of "who can we actually email", and there is no persona-based segmentation. The marketing team cannot quickly answer basic questions like "How many senior decision-makers can we email right now?" or "How many engaged contacts do we have?"

## Prerequisites

- Super Admin or Marketing Hub Admin permissions
- A HubSpot service key (`HUBSPOT_ACCESS_TOKEN` in `.env`; an existing legacy private app token also works) with `crm.lists.read` and `crm.lists.write` scopes
- Python 3.10+ with [`uv`](https://github.com/astral-sh/uv)
- ICP Tier property created and workflows processed (create-icp-tiers skill) — the script assumes the property name `company_segment` with values like `tier_1_primary_icp`; adjust its configuration block if yours differ
- Lead scoring model created (build-lead-scoring skill) is recommended but not required
- Lifecycle Stage property populated for customers and partners (fix-lifecycle-stages skill)

## Scripts

Script paths are relative to this skill's directory. Run them from your project directory so `.env`, `data/`, and `reports/` resolve there: prefix each path with wherever this skill is installed (`skills/build-smart-lists/` in a clone of the repo).

| Stage | Script | Run with |
|-------|--------|----------|
| Execute | [`scripts/execute.py`](./scripts/execute.py) | `uv run scripts/execute.py` |

`execute.py` creates the 10 foundation lists below via `POST /crm/v3/lists`, skips lists that already exist (409), and writes a CSV audit trail of created list IDs. There are no before/after scripts: the before-state inventory is a single Lists API query (see Before), and verification is a member-count review in the UI.
