## What it does

This skill handles custom object schemas in HubSpot CRM. It builds on `hubspot schemas` and its subcommands: `list`, `get`, `create`, `update` and `delete`. The first four run under OAuth login or a service key, while `delete` is service-key-only, so `HUBSPOT_ACCESS_TOKEN` has to be set.

Read `bulk-operations/SKILL.md` first. Every command here follows its JSONL conventions, and schema deletion uses the same dry-run, digest and confirm flow. Creating a schema starts from a JSON body: name, labels, `primaryDisplayProperty`, `requiredProperties`, properties and associated objects. Pipe it in or pass `--file`, and `--dry-run` previews the result before anything is applied.

Deletion is irreversible — it removes the schema and every record of that type. Run `--dry-run` first, then re-run with `--digest <hash> --confirm <name>` within 5 minutes. That is a good reason to double-check you are deleting the right schema. Once a schema exists, its `name` works as `--type` for the rest of the `hubspot objects` commands, so record CRUD, search and associations behave like they do on standard objects.

## Requirements
- Works with: HubSpot

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add HubSpot/agent-cli-skills --skill custom-object-management -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add HubSpot/agent-cli-skills --skill custom-object-management -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add HubSpot/agent-cli-skills --skill custom-object-management -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install HubSpot/agent-cli-skills custom-object-management
```

2. **Manually: put the files in place**
- File: `.github/skills/custom-object-management/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add HubSpot/agent-cli-skills --skill custom-object-management -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/HubSpot/agent-cli-skills --path custom-object-management
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add HubSpot/agent-cli-skills --skill custom-object-management -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/HubSpot/agent-cli-skills/tree/HEAD/custom-object-management/SKILL.md

## When to use it
- see which custom objects already exist in the CRM
- define a new object type with its properties
- rename schema labels without touching properties
- delete a schema along with all its records
- confirm that `--type` resolves to the right object

## Example prompts
- list the custom objects in HubSpot
- create the equipment schema from equipment-schema.json
- delete the pets schema using the three-step flow

name: custom-object-management
description: Discover, create, update, and delete custom CRM object schemas. Use when defining a new object type, inspecting existing schemas, or removing one. Record CRUD on custom objects is identical to standard objects — see `bulk-operations`.

  - "create custom object"
  - "custom object schema"
  - "define new object type"
  - "list object schemas"
  - "delete custom object"
  - "update schema labels"
  - "what custom objects exist"

## Source of truth

`hubspot schemas --help` is authoritative. Subcommands: `list`, `get`, `create`, `update` (metadata only), `delete` (destructive). `schemas list`/`get`/`create`/`update` work under OAuth login or a service key; `schemas delete` is service-key-only (`AppTokenOnly`) — set `HUBSPOT_ACCESS_TOKEN`. Read `bulk-operations/SKILL.md` first — every command here uses its JSONL conventions, and `schemas delete` uses its dry-run / digest / confirm flow.

## Discover existing schemas

```bash
hubspot schemas list                                       # JSONL: name, label, singular, objectTypeId, source
hubspot schemas list | jq 'select(.source=="custom")'      # custom only
hubspot objects types | jq -c 'select(.source=="custom")'  # same set, also shown to confirm `--type` resolves
```

`name` is what every other command takes. `objectTypeId` (e.g. `2-12345678`) is only needed for workflow `PLATFORM_FLOW` targets.

## Inspect one schema

```bash
hubspot schemas get --type pets
```

Returns the full definition — properties, associations, labels, `requiredProperties`, `primaryDisplayProperty`, `fullyQualifiedName`. Reshape with `jq` as needed (see `bulk-operations/resources/json-patterns.md`).

## Create a schema

Build a JSON body and pipe it (or pass `--file`). Minimal valid body:

```json
{
  "name": "equipment",
  "labels": {"singular": "Equipment", "plural": "Equipment"},
  "primaryDisplayProperty": "equipment_name",
  "requiredProperties": ["equipment_name"],
  "properties": [
    {"name": "equipment_name", "label": "Name", "type": "string", "fieldType": "text"}
  ],
  "associatedObjects": ["contacts"]
}
```

```bash
cat equipment-schema.json | hubspot schemas create --dry-run   # preview
hubspot schemas create --file equipment-schema.json            # execute
```

Add more properties later with `hubspot properties create --type <name> ...`.

## Update schema metadata

`update` patches labels / description only. Property edits go through `hubspot properties`.

```bash
````
