create-field

A guided tool for creating a custom field on a Salesforce object, such as a new field on an Account or Contact record.

In plain words
What is it for?
Use it to choose a field type, check for similar existing fields, set permissions and page-layout placement, confirm the details, and create the field.
Why use it?
It helps prevent duplicate fields and collects the settings needed for access, page layouts, and deployment.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-field scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/create-field.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Create Salesforce Custom Field

Guide the user through creating a custom field on a Salesforce object. This is a conversational skill — gather all required information through questions before deploying.

Workflow

User triggers skill
├── 1. Identify target object — which object gets the new field?
├── 2. Choose field type — present the type list, get user's choice
├── 3. Check for duplicates — run describe-object.js BEFORE gathering details
│   ├── Exact match found → STOP, tell user the field exists
│   ├── Similar fields found → show them, ask user to confirm or pick a different name
│   └── No matches → proceed
├── 4. Gather field details — type-specific settings (see tables below)
├── 5. Field-level security — ask which profiles/permission sets should have access
├── 6. Page layout — ask if the field should be added to page layouts
├── 7. Confirm all settings — show summary, ask for confirmation
├── 8. Create the field — run create-field.js
├── 9. Report result — show success/failure
└── 10. Offer next step — ask if they want to create another field

Phase 1: Identify Target Object

Ask which object the field should be created on. If the user already specified it (via $ARGUMENTS or earlier context), confirm it.

Describe the object to verify it exists and see its existing fields:

node ${CLAUDE_PLUGIN_ROOT}/scripts/describe-object.js <ObjectApiName> --fields-only [--target-org <alias>]

This gives you the full field list, which helps avoid duplicates and informs naming.

Phase 2: Choose Field Type

Present the available field types. Group them logically:

Basic Data Types:

Type Description
Text Single-line text (up to 255 chars)
Text Area Multi-line plain text (255 chars)
Text Area (Long) Large plain text (up to 131,072 chars)
Text Area (Rich) Rich text with formatting (up to 131,072 chars)
Number Numeric value with decimals
Currency Money value with currency symbol
Percent Percentage value
Checkbox True/false toggle
Date Date only
Date/Time Date and time
Time Time only
Email Email address (validated format)
Phone Phone number
URL Web address (displayed as link)

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
